Hi
i have recently installed a Multiplus 24/3000 in my RV and have a question regarding charging.
prior, I would adjust my charge current based on my needs on the day. I.e on grid it may be 50amps, on generator 20 etc.
I can’t seem to find a way to do this off the CC GX . I see I canuse ESS but I don’t want to limit solar charge etc, just the Multiplus Charger.
is there something I can enable to do this?
thanks
DVCC and ESS limits are global, so will affect all charge sources.
You can change the inverter AC input current limit on the GX, but the DC charge limit can only be done via a config change - pushed remotely via VRM, or with a mk3 and victron connect/veconfigure.
You can try use the large image (don't think it is supported on the old CCGX) and node red. With the custom control node for the vebus system you can probably set it via /DC/0/MaxChargeCurrent (haven't tried it myself). If that works you would be able to change it via a custom dashboard that is web accessible locally and remotely via VRM.
Hi @ryang1979
Given you're fairly new to a Multiplus, I think you need to clarify whether you need to set this "current limit" on your battery charge or your system as a whole.
You mention setting 20A on a generator. That's easily set in several places as it's quite common to do this. It's called 'Input Current Limit", and will allow the genset to operate at stable output. That AC power is first used to serve loads on the Multi, and the remainder to charge batteries. On a day you use a genset your batteries will effectively be '20A' better off.
A 'Charge Limit' is for limiting charge to the batteries only. The Multi's limit needs to be set there, and DVCC can be used to limit the total of multiple charge sources to the battery.
What is this limit you see in the CCGX that you can't change? Screenpic?
You can use the use the motorhome as below to limit the AC input for the shore / generator as you mentioned. Enable in display setting and then swipe from overview screen to it.
Cool. Thanks guys
i get it now, a different way to solve the same problem.
thanks for the responses.
