Hi guys,
Looking into this unit as well for new off-grid system in Italy. Found some recent
firmware updates and statements from Victron:
UPDATE 2023-5-26: fw v1.12, that adds parallel and three phase capability for the Inverter RS (not yet Multi RS) was released last week. Includes parallel redundancy. For now see changelog; and in a few days we’ll announce on
https://professional.victronenergy.com/news/ as well. Next up is three phase for Multi RS, which is expected to take take a while.
Scanning through that thread I also see more support for US users is coming (although it has been taking longer than planned):
being able to operate the Inverter RS in parallel, split- and three-phase it will happen some day. Using the VE.Can comms port.
It might be in 2022 or maybe in 2023. Its clearly something we want and are working on.
Scanning through tech specs for
Multi RS Solar (hybrid) Parallell and 3-phase operation is indeed NOT yet supported
BUT: It is supported for the product of this thread,
Inverter RS Smart Solar (off-grid).
I'm still a beginner and would like to learn more about this model, and try to find all the components to go with this system. Grateful for any help and suggestions of recommended/required components to go with it!
- Will it integrate well with seplos EVE cells and BMS. Something like
Apexium DIY Kits or
Seplos mason kit?
- I feel like 4kW of PV input is a little low. I guess the "6000" is referring to the inverter.. I'm wondering if I have to parallell with the same unit, or if it would be possible to combine it with a pure charge controller like
SmartSolar MPPT RS if I only need more input? Do you think the Input/Output spec seems balanced on this unit? Comparing to growatt SPF5000ES they instead offer 6kW input and 5kW output. I think I would have preferred that..
- I'm confused about the optional PV array in the picture mentioned earlier (below). I don't understand what this is intended for or how to use it.
@mrdavvv mentions: "If your loads are mostly during the night, or you are not connected to the grid, probably the separate MPPT chargers would be better." So I should just add another unit to add more PV input instead of using this feature?
In the instruction manual of the RS 48/6000 230V I found this picture:

Either way, after comparing options of buying separate Victron modules, this unit still seems to offer clear value for off-grid at 2250€.
- A separate charge-controller
MPPT RS 450|100 would cost ca 1200€ (with 5.7kW max PV input though, 2x 3kW tracks?)
- A MultiPlus-II Inverter/Charger (5000W so 1000W less) seems to cost around 1800€.
- So tot ca 3000€ for similar performance modular.
Are there any other benefits/spec details to consider in this unit compared to other products?
Thank you for you time!
