Obviously I need to balance my batteries with this setup.
I’ve looked at the Victron Battery balancer, and I have a few questions about it.
It will at most balance with 1A current between the batteries, and only when the solar panels are charging the batteries. Is 1A really enough for such large batteries? In 1 day it could at best balance around 10 amps between them (5% of rated battery capacity).
Is it any way to make it balance when not charging? I would rather have it start to balance when the voltage between them pass a certain difference, for instance 0,2v.
Are there any better options for me than the Victron Battery Balancer?
Not sure if this helps I have four 135ah lifepo4 batteries at 12v running in series parallel to give me 24v. I use a Victron battery balancer and it has been installed for3 years now. It appears that it only works when charging either by solar, Shore charger, or dcdc charger.
Sorry I should have said that prior to installing I was having issues with one of my batteries being undercharged
How many you need does depend on how fast you charge and how different they are in internal resistance.
It is always best to top balance not balance all the way through the voltages.
Yes you can connect 2 to the same bank.
And yes, on a 24v system. I have done it.
It literally says you can on the product page.
The shunt also has midpoint monitoring, so you can monitor it.
