Have a friend who has bought a Victron Multiplus -II 48/5000/70 for their offgrid house and wants to use their generator on the AC input to charge the battery bank via the inbuilt charger, BUT- their generator is only 4kVA- and the charger seems to be set at 32A (so 7400W ie nearly double what the generator can handle…) Is there a way of changing that limit WITHOUT a laptop or internet access (its a remote location with no internet access, and neither of us owns a laptop with windows) ie can it be done via the phone app in any way???
Done a lot of offgrid installs, but never used Victron before- their apps seem quite limited on what they can do in comparison the the inverters I prefer to use- from my glancing over the manuals- it appears I need a windows laptop and a special lead to program them???
Sure hope not…
OUCH another 300 bucks???
Be cheaper to buy a new generator…
Seriously- the inverters I normally use its literally done from the phone app- so far I’ve not been impressed with what they got for the money they have spent so far…
Now I need to drive for three hours to the nearest dealer and shell out more of their money just to gain access to the settings???
There is no way to access the settings without all this???- its literally a ‘do it once and never touch it again’ thing- something that ‘should’ be easily done without needing anything extra…
If thats the only option, I might recommend them sell it for whatever they can get and I’ll put in my preferred brand…
Been looking at this- seems to be usable with windows computer only sighs I’d have to see if I can borrow one (the last windows computer I owned was still running XP- I use Linux…) Seriously over this POS, i’m so tempted to rip the whole lot out and fit a decent system that doesnt need ‘special gear’ to be able to do anything with it…
They paid about a third more for that blue paintjob, and its been a nightmare from the start…
For me Victron is better, cheaper and easier to handle then the other main brands, has a great support, lots of information on their website and, and, and…
They paid as much for a 5kw inverter as I do for a 12kw one, and now it looks like they got to shell out more to do basic stuff like accessing the settings- stuff that I can do on the Sigineers just from a phone app locally via the inverters hotspot API with nothing more needed… (so far I have found the mk3 (needs windows or apple computer) or the $$$ Multicontrol, or the remote VEConfigure (needs internet access… which there isnt at his location…)
The victron MultiPlus 48/5000/70-100 (MPN PMP485021010) is a combination of 48V 4000W inverter and battery charger. The integrated battery charger provides 70A which allows quick charging even for bigger batteries as long as there is a grid connection.
The 48V sine inverter converts your DC battery current into a 230V AC current. Thanks to a pure sine wave this inverter is also suitable for sensitive electronic devices. Besides those two components there is also an integrated transfer switch that enables you to realize many grid-tied solutions.

Thats the price in Australia for the blue…
Plus it doesn’t have inbuild MPPT (the Sigineer has two 60A 250v MPPT charge controllers built in), there’s close to another grand…

I suspect I found my answer lol- found a 48v 60a forklift battery charger they can plug into the genny and just ignore the inverters inbuilt one- costs $80 less than the victron controller to boot…
Sighs, thanks for the help…
Thats what the inverter draws from the mains supply- 32A at 230v at 100% charge output, according to the manual (and it definitely trips the genny out after nearly stalling it lol)- I was hoping to throttle the charge rate back to the point it didn’t stall/trip the genny out, which the Victron is supposed to be able to do- but with what I have available, it seems its way more trouble (and $$$) than simply ignoring its inbuilt charger and simply using an external one…
