Transcripts

hey thanks for joining me this is just a

quick video kind of a followup to the

video that I did on this uh Dobson DBS

3500 about a month or maybe five or six

weeks ago but then I showed you uh how

you could use this with an expansion

battery and it makes a very nice

versatile budget portable home backup

system or portable power station either

way you can kind of take it with you

it's got a dolly handle and wheels and

uh it's got battery expansions and and

terms of cost per wat hour it's one of

the the better budget options out there

that I have seen well in today's video

we're going to take a look at how you

can connect two of these DBS 3500s

together to get a split phase 240 volt

output and to do that you obviously have

to have two of the DBS 3500s and by the

way if you haven't seen the the

individual video that I did on it uh

I'll put that in the video description

below and you can go check that out I

highly recommend that this will make a

whole lot more sense if you if you do go

watch that but uh back back to this

topic where we're going to look at this

240 volt split phase configuration now

you do need this parallel box that that

they ship with this and on this it has

an l450 connector even though this

really is a 30 amp output it's a maximum

of 30 amps but it does have an l450 type

kind of the same thing you would use for

a a dryer also very common for uh for

RVs as well and then it's got an l1430

twist lock over here and uh and you can

actually get 240 vol Vols out of either

one of these two or you can get 20 amps

120 volts out of either one of these two

but again uh maximum 30 amps out of the

the whole thing and basically there's

just two cables coming off this as you

can see on the top and those wrap around

and they plug into each of these DBS

3500 Infinity ports on the side and they

just plug right in there and then all

you have to do is power up the units

it'll detect that there's this parallel

box attached and then you will kind of

reboot itself to set the split phase for

you and then you're off to the races so

let's uh let's go ahead and do

that and like I said they'll kind of

boot up and then they'll shut off and

then they'll boot up

again now they're powering

down and they are coming back

up all right so they're pretty close in

charge 98% 99% now typically when you're

you're trying to get 240 volt output is

because you want to be able to power

larger appliances in your house like

your dryer or some big monster electric

water here like this or your furnace

which actually doesn't typically take

240 volts but your central AC will but

do be aware even though these are rated

for a continuous 3600 watts of AC output

uh each at 30 amp Max is not going to be

enough to allow you to handle the inrush

current on a typical sort of uh two to 4

ton U house residential uh central air

conditioning unit so this would not

typically be appropriate for that kind

of use uh but it would be appropriate if

you wanted to use it for a window air

conditioner or a floor air conditioner

something like that now um you have a

couple of options as I said you could

you could use a standard generator cable

which is usually these l1430 twist locks

and actually that's what I've got there

that's what I've got plugged into my

manual transfer switch and it's got a uh

a maale end on this side side here but

before we do that we're going to check

and make sure we're actually getting 240

volts out of both of these ports um now

if you wanted to use the

l450 to connect to an l1430 on your uh

manual transfer switch

well you can do that with a simple uh

adapter like this where this would go

into the manual transfer switch and then

this would just this l450 end the dyer

style plug would just Connect into there

now since I happen to have a longer

generator cable any anyway it actually

came with my manual transfer switch up

there I'm just going to use that rather

than than this adapter I just picked

this up so I'd have another option if I

ever needed it and also to be able to

show you that these things are out there

and they're easy to find now um you do

when you're setting up your manual

transfer switch and by the way I I will

leave a link to that video as well in

the description below it's much easier

to do than you might think uh although

check with code in your area to make

sure it's not required that you use a

licensed electrician for that or that a

inspection is not uh required but it's

always recommended even if it's not

required have it inspected make sure you

didn't violate any codes things like

that because you do not want to burn

down your house or injure yourself or

anybody that you care about so all that

uh disclaimer aside yeah you do want to

make sure you get your circuits

relatively balanced off of the two 120

volt legs that are coming into your

residential service I know I have some

viewers in Australia and you guys are

running off of 240 so this is different

for you this is uh applicable to here in

the US uh but you do want to make sure

that your circuits are relatively evenly

distributed in terms of load across

those two legs and that's especially

important when you're using split phase

240 where you have two units two

separate AC inverters up giving you the

the power for those two legs because if

you have them imbalanced it will drain

the capacity of one faster than the

other and then it's the lowest common

denominator the one that runs out first

the whole thing is going to shut down

since it's in 240 240 mode so just be

aware that you can add expansion

batteries but uh you wouldn't want to

add one expansion battery to this with

two units you'd want to add two so both

of these units had the same capacity to

draw from so just be aware of that or

you could add two expansion batteries

and uh two to each one so total of four

if you really wanted to go nuts with

this now by themselves they have uh I

think they the capacity is 3,420 W hours

I believe so you have almost 7,000 wat

hours of capacity which just two two of

these main DBS 3500s and then combined

it will give you a maximum 240 volt

service of up to 7,000 Watts uh actually

probably 7200 Watts because you're

getting 3600 watts each uh unit all

right let me get my multimeter here and

let's uh let's test the output and make

sure we are actually getting 240 volts

make sure I'm in AC

mode

oh use your error you actually do have

to turn on the AC inverters just because

it came up like this it's ready to to

start the timing but you have to turn on

the AC inverter for both

units there heard both relays kick on we

should be good to go now let me check

the voltage there we are

238.9

volts so we're getting our 240 volts let

me go ahead and plug

in my manual transfer switch I'm going

to use the l1430

connector since I can only get 30 amps

anyway all right and I do have there's a

little red light a little red LED on

here by the way that tells you that this

thing is

live right now I can switch over my

loads up here so I'll start with my hot

water heater and uh let's just go ahead

and start loading this

up all right so I pretty much put this

entire subpanel or at least the 10

circuits that I have mapped over here

onto this this and I don't have a lot

running right now so I'm only pulling

137 Watts let me see if I can get the uh

hot water heater kick on make sure we

can run

that all right I'm running some hot

water to kick my hot water heater on

here hopefully here in just a little bit

but this is a an example here one of my

legs uh off of one of the phases of that

240 volt I'm pulling 138 Watts so pretty

small load but I'm not pulling anything

off the other side right now on all the

circuits that I've flipped over now

that's going to change in just a little

bit once the hot water heater kicks on

but this kind of illustrates why it's

important to make sure that you're

relatively balanced otherwise like I

said you'll drain one of the units

faster than you drain the other and then

whichever one drains uh empty first or

goes to the low state of charge first

and has to shut down it's all shut down

so just be aware of that by the way this

is absolutely plenty of power to be able

to run your furnace in the winter time

if you just need heat if you have a gas

or propane furnace this will definitely

handle that because that actually runs

off of 120 and those typically pull

about uh somewhere between 600 to 700

Watts when they when they run it's

mostly the blower that is consuming that

power and then some of the other

electronics around that but definitely

possible to power furnace uh with one of

these at least a gas furnace if you

happen to have electric heat in your

house you have a sense for how much uh

how much watt power that actually draws

I'd be curious to know I'm guessing it's

going to be quite a bit more than 7,000

Watts uh but I don't have electric heat

so I'm not really quite sure how much

those actually draw I'm just guessing

it's a lot more than this so as you can

see and possibly here the uh big

electric water heater here to my left uh

is actually running now we are pulling

2800 watts here on this one and uh 2600

Watts here on this one while I was off

camera my my sewage pump actually kicked

on because I was running a bunch of hot

water down here in the downstairs

basement and this bottom one spiked up

to 3900 Watts for just about 3 or 4

seconds as the pump ran and then it went

back down and there it goes right

there so we are at temporarily it spun

up to 3900 Watts but it did not shut the

system down it was able to handle that

pump surge while the electric water

heater was also running now one thing to

keep in mind when it is actually

providing AC power in Split phase mode

you cannot recharge it via AC you can

only recharge it via DC so that's kind

of an important thing to be aware of so

if you're going to be using this long

term you need to be prepared to recharge

it uh in a power an extended power AIO

situation you need to be prepared to

recharge these things via solar uh or

some other DC input in order to recharge

them not via AC because you'd have to

disconnect them in order to uh recharge

them in AC mode which you could

certainly do uh but you have to take

these uh take this little uh parallel

junction box and disconnect connected in

order to do that so just be aware there

is that limitation but I do find this to

be an extremely capable Budget Home

backup power system uh despite its

actual budget price and I've been very

happy and and really delightfully

surprised at how this unit performs in

the four plus months that I've had it

just uh seems to tick all the boxes yeah

so I'll put information in the video

description below if you want to go

check it out and I do highly recommend

you check out the video that I did it

was a little bit longer format on on the

single unit with an expansion battery

just so you get a better sense of what

the specs are uh but highly recommend

checking that out and the links I've got

for you in the description below so hey

if you found anything of use uh or you

learned anything in the video you found

interesting please consider giving me a

thumbs up on it I'd very much appreciate

that and I do thank you for joining me

for this video I do hope to see you in

the next one as well until then have fun

out there
