I've read the posts about folks using an inline resister to pre-energize an inverter before connecting directly to an LiFePO4 bank. (problem was capacitors blew because they received power too quickly). And yes I plan on having a breaker in there so not exactly directly.
Is this still necessary with Daly BMS's controlling a 200amp relay on the load from the LiFePO4 bank, and the current passing thru it?
Are my inverters small enough to NOT require it?
Here is the system I am implementing (top diagram):
And if I need to pre-energize, any idea how to automatically and momentarily pre-energize the inverters? Seems missing from this diagram... I intend to have only 1 inverter attached at any time in case that matters.
Thanks for any info or ideas!
The more I read, the more questions i have... isn't it supposed to be the opposite?
My system:
200AH 12v LiFePO4
Daly 45amp Separate Port BMS
Inverter #1: Giandel 12v 1200watt Pure Sine Wave
Inverter #2: Xantrex Pro Watt 12v 600watt Pure Sine Wave
Inverter #3: Samlex 12v 400watt Pure Sine Wave
