Keywords

💡Inverter

An inverter is an electronic device that converts direct current (DC) from sources like batteries or solar panels into alternating current (AC), which is used by most home appliances. In the video, the inverter plays a central role in the setup of the energy system, managing the power distribution between the grid, battery, and home appliances. The video focuses on configuring this inverter to ensure it doesn't feed excess power back to the grid.

💡Battery settings

Battery settings refer to the configuration options available for managing the inverter's interaction with the connected battery. These settings determine how the battery charges and discharges, and protect the battery from being overused. For example, the script mentions setting the shutdown level at 10% and ensuring that the battery doesn't discharge below 35% to avoid draining it excessively.

💡Zero export

Zero export is a setting on the inverter that prevents excess energy generated by the system from being sent back to the electrical grid. This is important for systems that are designed to manage self-consumption without feeding energy back into the grid. In the video, this feature ensures that all the power produced by the solar system is used within the house, and none is returned to the grid.

💡Asymmetric phase feeding

Asymmetric phase feeding allows the inverter to distribute power unevenly across three phases based on the actual consumption demand, rather than distributing power equally across each phase. This is useful in optimizing the system’s efficiency. The video explains how this setting is enabled to meet the varying power demands of different appliances connected to the inverter.

💡DIE Cloud

DIE Cloud refers to the cloud-based platform used to monitor and manage the inverter remotely. In the video, the DIE Cloud app is introduced as a tool to connect the inverter to the local network via Wi-Fi, and monitor power generation, battery status, and consumption through a smartphone interface. This feature enhances the user’s ability to oversee the energy system.

💡Grid settings

Grid settings refer to the parameters that define how the inverter interacts with the electrical grid. These settings involve configuring the voltage, phase rotations, and frequency to ensure compatibility with the local grid infrastructure. The video mentions that the default setting (vde 4105) is typically appropriate for home use, and it ensures that the inverter can synchronize correctly with the grid.

💡Hybrid inverter

A hybrid inverter is a type of inverter that can manage both solar power and energy from a battery while also interacting with the electrical grid. This type of inverter allows for more flexible power management. In the video, the hybrid inverter is showcased in a test setup where it manages energy from solar panels, a battery, and the grid, depending on the system’s configuration.

💡Shutdown and restart levels

Shutdown and restart levels are safety thresholds that manage when the battery should stop discharging (shutdown) and when it should start recharging (restart). These are critical to avoid damaging the battery. For instance, the video mentions setting the shutdown level at 10% to prevent over-discharging during off-grid conditions, and restarting the battery charge at 50%.

💡Time of use table

The time of use table is a scheduling feature in the inverter that allows the user to define when the battery should charge and discharge, based on the time of day. This is particularly useful for optimizing energy usage during peak and off-peak hours. In the video, it’s mentioned that the default setting discharges the battery up to 80%, and adjustments can be made to lower it to 35%.

💡Wi-Fi configuration

Wi-Fi configuration is the process of connecting the inverter to the local network, enabling remote management and monitoring via the DIE Cloud app. The video provides a step-by-step guide on how to scan the inverter’s QR code and connect it to Wi-Fi, which is crucial for accessing real-time data about the system's performance and status.

hi everyone I'm Norby babos the

technical manager at solar kit in

today's video we'll be setting up a die

inverter what makes this unique is that

we're here in Ningbo at the D Factory

behind me you can see a small test wall

with this hybrid inverter connected to a

battery as you saw when we turn on the

inverter it immediately starts beeping

indicating there's an issue so let's fix

this first so we can hear the rest of

the video clearly normally you can find

the settings in the top right corner in

the basic settings we need to disable

the beep function so the inverter won't

make that noise basically it's important

to know that the electrical Network here

is the same as home

so we have 230 volts between neutral and

phase and 400 volts between phases so

there won't be any differences in the

network so the basic settings that we

have to go through and set up are

assuming a back wattage system where we

have a battery we can't feed back to the

grid we have to feed back asymmetrically

and we want to power the house with

solar energy both day and night so by

default in the battery

settings we have a 5.1 prob die battery

so that's because the inverter

communicates via cable so we can select

the lithium battery option here in the

battery mode

[Music]

[Music]

we select the lithium

check back to battery settings there's a

lot of menus underneath here actually

gen charge gen signal and grid charge

grid signal which tells you from the

generator if connected to it or or from

the mains to charge the battery

by default these are we don't want to do

these because we're just putting

together a relatively simple system so

here we need to uncheck all the

boxes to make sure the battery doesn't

charge from the generator or the grid

now the next menu item here is battery

settings lithium mode is the 0 0 this

basically tells you if you're

communicating with the battery via cable

then uh which protocol the inverter uses

to to communicate with the battery the

whole charging and discharging if we set

it correctly then it will tell us here

that we have a die type battery on it

and the percentage values underneath

this is shut down low battery restart

and this is are given as Factory values

now if we come up from the bottom the

50%

is value where if battery is discharged

then the inverter will then charge it to

at least 50% and then it'll just draw it

down before it touches It Low battery is

35% that's the value which is for Main's

operation so if you have a network it

will allow the battery to discharge up

to

35% and at that 35% it will turn it off

and start charging it to at least

50% shut down the 10% is the value when

we have a power outage or we're in off

grid and we don't have AC power it'll

let you discharge up to

10% the battery and then it will start

charging ing to 50 by default we don't

have to touch that it's set up just fine

system work

[Music]

mode we have a lot of things connected

to the inverter right now but let's

assume that our load Port is not

connected and we only have a simple grid

tide system so we have zero export to CT

enabled which means it will monitor the

pad loocks on the load port to ensure

they're being used and it won't send any

Excess power to the grid if we had

selling first enabled it would send all

the energy back to the grid it wouldn't

measure anything or care whether there's

any reverse power everything would just

go directly to the grid with zero export

to load enabled no energy will be sent

to the grid instead all the energy will

uh be directed to the load Port

depending on how much consumption we

have there we have zero export to CT

enabled and since our system has reverse

power

we don't check the solar cell option

this option is for when we can feed

excess energy back into the grid this is

not relevant for us

here the next menu maxel power is the

one that gives the power when uh we can

set the maximum amount of energy that

can be sent to the Grid on the AC side

this is a 12 kilowatt inverter so a

total of 12 KW can be sent back

obviously that if it were allowed to

back feed and next to that is zero

export power that's 020 that's in Watts

this is the minimum amount the inverter

we'll always draw from the grid to

ensure there's no feed in that um

there's no feed in acting as a small

buffer or reserve on the consumption

side this can be set up to a maximum of

500 watt so we can set it so that if our

power demands on the

consumption side change rapidly we all

always draw 500 WS from the grid this

gives the inverter enough time to adjust

and compensate for the fluctuations this

way we can prevent any unintentional

momentary feeding when the consumption

suddenly drops ensuring no excess energy

is accidentally sent back to the grid by

default this is set to 20 wats and the

manufacturer doesn't recommend changing

that they design and optimize the system

around this 20 W

setting it's only worth adjusting this

if you notice that some energy is a

tionally being fed back into the

grid the grid Peak shaving feature which

we don't need to use at the moment

allows us to set a limit on the amount

of energy that uh that can be drowned

from the grid this can also be limited

in Watts for example if we want to

ensure that no more than 5 KW are are

drawn from the grid then we would enter

5,000 WS into this setting this menu

point is checked off since we've set

everything up

the next page is time of use

table now by default if the time of use

table is not

checked the inverter can only charge the

battery as long as it's connected to the

grid but it can't discharge it if we

want to enable the feature to switch it

on obviously it's to discharge the

battery in systems with reverse power

not just charge it we need to check the

time of use table this allows us to

manage battery discharge by default the

factory settings for the battery value

here are set to

80% these configuring values specify how

much the system will discharge the

energy stored in the battery while also

protecting its longevity so in this case

it will allow the battery to discharge

up to 80% so it's worth adjusting this

to the 35% that was set in the battery

settings menu so here we'll just click

on the 80% value and start decreasing it

until it reaches the allowed limit it

will automatically stop at 35%

% because that is the preset limit for

the battery we'll lower these values

down to

35% and once we've got all the

percentages down to 35 we can save the

settings by checking the Box we don't

need to check the grid charge and

Generator boxes here as they specify

whether we want to charge the battery

from the Grid or the generator during

the specified time period at the moment

this is not an option for us so we don't

need to adjust anything else we just

need to Simply check the box in the menu

below we have all the days from Monday

to Sunday selected allowing us to use

the battery every day of the week this

setup is perfectly fine as it is and

ensures that the battery is available

for use at all times next menu item is

the grid settings it has automatically

detected the vde 4105 which is the same

network setup we have at home this is

what we need to set it to we have 50 HZ

and the phase type should be either 0

120 240 or 0 24010 it depends on how the

phase rotations are connected at the

specific Transformer where the house is

located so I would suggest that we leave

it at the default factory

settings if the system indicates off

grid and doesn't start we need to switch

to the other setting after that it

should work fine we won't be able to

determine in advance how the three

phases are connected with

truffle here at the grid level we need

to set

Ln to 230 volts meaning we have 230

volts between the neutral and the phase

between phase and the phase it should be

around 400 volts and this is what needs

to be set here and uh if everything is

set correctly here we can check this off

as well in the grid settings there are

many more options further down but we

don't need to change them by

default these settings are all

automatically configured with the grid

code so there's no need to adjust

anything in the grid settings after that

in the advanced

functions there's really only one thing

that's important for us at home the

asymmetric phase feeding this setting

allows the system to feed power back

asymmetrically based on the consumption

demand across the three phases rather

than symmetrically with an equal amount

on each phase so we enable the

asymmetric phase feeding and with a

check of the box it is already activated

the signal Island mode is necessary when

operating in off- Grid mode without the

connection to the main grid

in this case it will bond the neutral

and ground at the output it is advisable

to enable this feature when in such a

setup in the advanced functions there's

also the wind turbine option currently

this feature is not included in the

latest firmware of the new inverters

because the manufacturers are still

developing a small control box that will

be connected on the DC side to allow for

the integration of wind turbines once

this control box is available the wind

turbine option will be reintroduced in

the latest firmware updates at that

point it will be possible to connect a

wind turbine directly to the invert on

the DC side using this control box for

now since the control box is still under

development we won't go into this

feature and finally we have the parallel

menu if we have multiple inverters

connected in parallel we can enable this

feature here in this menu we specify

whether each device is a master or a

slave and assign its serial number

essentially the master inverter is set

as number one and then the subsequent

slave inverters are number 2 3 4 5 and

so on these settings need to be

configured accordingly

and here is the last function the X

meter for CT this option needs to be

checked if we are using an external

current meter such as a smart meter

instead of the factory clamps included

in the package in this case we need to

check this option and specify the make

of the smart meter we are using so

that's basically all we need to set up

in the advanced functions

menu uh we don't need to worry about the

Gen Port used for now because it's

connected but not currently in use we

also don't use the smart load output for

a simple grid tide system with reverse

power we don't need to adjust these

settings at all leaving them at the

default Factory values will ensure

everything works

perfectly now in this video we can begin

using the die Cloud for managing and

monitoring which will be fully

operational and available for use

starting around May so we open the

dcloud app on the phone and from this

point on you'll be be able to see the

phone screen to get a better idea of how

everything looks and works so we open

our dcloud interface at the top left

you'll see our company name and at the

bottom right there's some information

about the company and your user account

click on the three little lines at the

top right then select Wi-Fi

configuration to connect your device to

the local network

Wi-Fi now it's best to log into the app

while already connected to the local

Wi-Fi network doing so ensures a

smoother setup process because you won't

have to enter the Wi-Fi password twice

once you're on the network scan the QR

code of the inverter or its

antenna then press confirm to verify the

number displayed under

SN it will immediately recognize that

your phone is connected to the local

Wi-Fi network you just need

to enter the password for the local

Wi-Fi

network the logger's password will be on

the bottom of the logger

itself the serial number is on top and

the password is below it you just need

to enter the code that is printed on the

dongle

itself once we connect we immediately go

back to the die Cloud app Grant it all

the necessary permissions and allow it

to access the devices the app will then

guide us through the steps to connect

the logger to

the local Wi-Fi network if this process

is

successful it will confirm the

connection indicating that our device is

now on Wi-Fi from there we can proceed

to create a site so we successfully

connected to the Wi-Fi from this point

on our device is online to create a new

site go back to the main menu click on

the three lines at the top right and

select create

plant it will then take you to the

screen where you can create a new

site it's a good idea to disconnect from

the inverter's wi-fi at this point since

it won't have much internet access

instead use your local Wi-Fi or mobile

network for a more reliable connection

for plant name we now enter D test

center it's very important to set the

correct time zone for the location if

you enter the wrong time zone this

mismatch will result in discrepancies

between the data and the actual time

accurate time settings ensure that the

monitoring do is synchronized correctly

with real-time events providing precise

and reliable

information

so this is important and

then for system

type select storage system because we

have a battery for insert capacity into

the amount of solar power on the roof in

kwp let's say it's 10 KW yes for

longitude and latitude enter the

coordinates it will fetch the necessary

details which should be accurate for our

needs we're at the die

Factory now it shows that our site has

been created but no logger is associated

with it yet so we click on ADD now and

scan the QR code of the logger we check

the SN to make sure it matches the one

on the

logger the last digit should be 884 and

if they match we confirm the system will

then add this logger to our site at this

point the site setup is complete with

the device integrated the final step is

to assign an end user to the site to do

this click on the three dots at the up

right corner of the screen select manage

access then go to authorize users here

click the plus sign and enter the email

address of the user you want to assign

this will grant them access to Monitor

and manage the

system once it finds the user we can add

them and choose their permission level

permission level only view can edit or

and manage for the end user only view is

usually sufficient for them to see the

site statistical data however if we want

to provide deeper access we can give

them full administrative rights allowing

them to manage the site from their phone

entirely this depends on individual

preferences and what access they need uh

by default only view is enough for most

users the can view option is more than

enough for users to check the

statistical data with this setup we have

successfully commissioned our inverter

created the site and added the user the

system is now fully operational this

covers the basic setup of the inverter

for a reverse power system with a

battery allowing a symmetric feeding to

only cover consumption without without

feeding energy back to the grid broadly

speaking I think we have covered all the

important

information

so if you have any questions feel free

to contact our team you can reach us by

phone and we're happy to assist with any

commissioning issues

so good luck with your die

system see you in the next video
