I have two EG4-LifePower4 48v Lithium Batteries, and one Growatt 3kW Stackable Off-Grid Inverter (the 2nd inverter in the photo is for future expansion). I have Bus bars to arrive soon in the mail.
My questions are:
Do I need to Top Balance the batteries?
If yes, what is the best way to do this?
(I have a EG4 Battery Charger - 48V 18A)
Then this question:
Even though this is an Off-grid system, I have easy access to 120v 20amps of power – Is it a good idea to keep the charger connected to the bus bar so to always have the batteries topped off?
(I was told not to do this as the as it would hinder the batteries from cycling normally)
