EG4 6000XP compatible with 4 x 12v Renogy 200ah Lithium batteries in series to make 48v??

[deardustin]

I'm curious if the EG4 6000XP is compatible with running 4 x 12v Renogy 200ah Lithium batteries run in series to make 48v as the battery bank for this all-in-one unit?

Sure, it will work no problem.
But four 12V batteries in series will cause you problem soon or later.

No problem for the 6kxp. But rebalancing the batteries occasionally, will get old quickly.

 

[deardustin]

What kinds of problems and how fast do you think?

Is there some way to auto balance them in line? How often will this be an issue do you think? It will be my main system living off grid...

What kinds of problems do you imagine? why would the 4 x batteries in series have a harder time than a server mount or wall bank?

Gotcha, is there anything to be done about that while the 4 batteries are run in series to achieve the 48v?

You can add a battery balancer. But it's much better to just use the correct voltage battery.
How often is different for everyone. It depends on how much you work the batteries.

Fair enough, basically what I'm trying to solve for is that I already have 3 x 12v Renogy 200ah LiPo batteries... we are realizing that our power needs are going to increase and so I'm trying to just add another battery and upgrade the system from 12v to 48v by adding the EG4 6000XP, in the hopes that solves for upgrading the charge controller and inverter all-in-one etc. If we add the 4th Renogy battery and run them in series it all adds up to that 48v current needed for the EG4 6KXP.

This is a waste of your hard earned money. Renogy batteries suck. Just ask me how I know that. Don't spend another nickel going down that rabbit hole.
For a bit more cash than a single 12v 200ah Core series battery you can buy a 48v 100ah rackmount battery. Then sell your junk three batteries you have to the highest bidder and then buy a second rackmount with that money.

I understand.
But when you are ready to expand your battery capacity, buy 48v batteries.
