Is a Victron Multiplus-II a good option for this?

[Deudorix]

Hi all,

I've been experimenting with off-grid all-in-one setups for a few years now, mostly with used lead-acid and AGM batteries that I have been given and then combined into 48V battery banks. I've used the EG4 3000EHV-48 inverter, and have had a good experience with it.

I've decided to purchase a new battery bank, which will be a 48V battery bank made up of U.S. Battery 2200 XC2 6 volt batteries. I've chosen that specific battery because I live in a remote location where I can't get batteries shipped to me (due to hazmat limitations), but I can get these from a local business.

I'd like to set my new system up properly to get the maximum life out of these new batteries, and I need to purchase a new all-in-one 48V charger / inverter to go with these new batteries. I'd like to get a high quality inverter, and I like Victron products, and so I was considering a Victron MultiPlus-II 3000VA.

The 2200 XC2 6V batteries are a flooded lead-acid battery, and the manufacturer recommends using either three-stage charging (constant current, constant voltage, constant current) or two-stage charging (constant current, constant voltage). There is good documentation for these batteries, with specific voltages for Bulk charging, etc (constant current to 58.8V)

My questions:

• Is the Victron MultiPlus-II a good option for this new battery bank? Looking at the Victron manual I see values for absorption and float voltages that don't match the batteries (Victron for example says 57.6V for Absorption). Can these be changed to match the battery specs?
• I'm limited to using these specific batteries. Is there a different all-in-one inverter that would be a better option than the Victron MltiPlus-II?

Thanks!

Yes its is
But not a 3000ve model .
The really watts are about 2200watt .
So go for the 5000ve model that do 4000watts .
The ve means if you use halve sinus wave electric stuf.

Are u use 120 or 230 volts in your house ?

For the rest .
Victron support use setup
Means you can adjust all volts for charging how you like it.

Go to the app store
Go for Victron connect app
Its have a demo option from all the Victron unit.
This way you can see how to adjust and how it works.
For you go a pay one .

Thanks so much @Suijkerbuijk, that's really helpful. I used the demo version of the app, and it was great. I'm 120V in the house, and will look to get the 5000 model.
