Easy Solar vs Multi RS Solar: Which Victron Product is Better for You?

Summary

In this video, Mike Hayden compares Victron's Easy Solar and Multi RS Solar systems, offering insights from over a decade of installation experience. He discusses the features, benefits, and limitations of both units, such as their voltage capacity, ease of installation, and remote monitoring options. While the Easy Solar is ideal for smaller applications like tiny houses or motorhomes, the Multi RS offers more flexibility with higher voltage input, dual trackers, and better usability in complex systems. Mike also touches on common challenges, including issues with generator auto-start and panel voltage requirements for RVs.

Takeaways

• 😀 Easy Solar comes with a built-in solar regulator (250V) and is available in 24V and 48V options, making it ideal for smaller off-grid applications like tiny houses and motorhomes.
• 😀 Multi RS has a higher input voltage (450V), making it more suitable for larger systems that require more solar panels and flexibility in panel configurations.
• 😀 Easy Solar is a simple, all-in-one unit that includes an inverter, charger, and solar regulator, making it easy to install and use in basic off-grid setups.
• 😀 Multi RS allows for multiple tracking inputs, supporting east and west-facing solar arrays, which increases system efficiency and flexibility.
• 😀 Both Easy Solar and Multi RS are integrated with Victron’s Venus operating system for monitoring and control through the VRM portal and Victron Connect app.
• 😀 Easy Solar is ideal for basic applications, but you can scale it by adding additional units like a MultiPlus inverter or an external MPPT solar regulator if needed.
• 😀 Multi RS offers more powerful performance (6 KVA vs. Easy Solar’s 5 KVA) and is better suited for larger energy demands, but it requires more complex installation and setup.
• 😀 Easy Solar is great for systems where AC coupling isn’t needed, but Multi RS can be used with AC-coupled inverters for more advanced integration with grid systems.
• 😀 Easy Solar is limited by its startup voltage requirement (120V), which can be problematic for RVs and smaller vehicles with limited roof space for solar panels.
• 😀 Multi RS can be used in three-phase systems, offering flexibility to manage multiple inverters across different phases, but it cannot be paralleled on a single-phase setup.
• 😀 Both products have been used successfully in off-grid setups, but the Multi RS provides more control and flexibility for larger, more complex installations, while Easy Solar is more suited to simple, standalone applications.

Q & A

What are the main differences between the Victron Easy Solar and the Multi RS Solar?

The Victron Easy Solar is an all-in-one unit with a built-in solar regulator and comes in 24V and 48V configurations with 3KVA or 5KVA inverter chargers. The Multi RS Solar, on the other hand, offers a higher 450V input for solar panels and is more suitable for larger systems, though it cannot be easily paralleled in single-phase configurations.

How does the Easy Solar handle solar input and voltage?

The Easy Solar supports a 250V solar input, which is more suitable for smaller systems, typically in the 24V configuration. It includes an internal Venus operating system for remote management via the VRM portal, making it easy to monitor and control.

Can you use multiple Easy Solar units together in one system?

Yes, multiple Easy Solar units can be used in parallel, but there are limitations on the number of inputs and the flexibility in monitoring, especially as the system grows. This is ideal for simple, smaller setups like tiny houses or motorhomes.

What are the benefits of the Multi RS Solar compared to the Easy Solar?

The Multi RS offers higher voltage support (450V), allowing for larger and more flexible solar panel configurations. It also supports dual MPPTs, which allows for independent tracking of panels facing different directions, offering more efficient energy capture.

Is the Multi RS suitable for three-phase systems?

Yes, the Multi RS can be used in a three-phase configuration, making it ideal for larger setups or commercial applications. However, it cannot be paralleled in a single-phase system.

What installation challenges exist with the Easy Solar?

One challenge with the Easy Solar is its limitations when scaling up beyond a certain size. The system's built-in Venus device restricts the number of inputs, which may lead to complications when trying to expand or integrate with more complex setups.

How do you manage remote monitoring with both the Easy Solar and Multi RS?

Both systems support remote monitoring through Victron’s VRM portal. The Easy Solar has the Venus operating system built in, while the Multi RS may require the addition of a Serbo device for expanded remote control and program management.

What is the main downside of the Easy Solar's generator auto-start feature?

The generator auto-start feature on the Easy Solar has been described as clunky and difficult to program, especially in newer models. It lacks the flexibility of a color screen, which complicates the programming process compared to older units.

Can the Multi RS be used for off-grid applications?

Yes, the Multi RS is suitable for off-grid applications, offering high-frequency technology for a lighter and more powerful 6KVA inverter. It is particularly well-suited for larger off-grid setups and can still be AC-coupled with grid-connected inverters.

Why might the Easy Solar not be ideal for RV or motorhome applications?

The Easy Solar requires a minimum solar panel input voltage of 120V, which may be difficult to achieve in an RV or motorhome setup due to limited space for solar panels. This makes it unsuitable for many RV applications unless the voltage requirements can be met.
