[RE-wrenches] Li Replacements for Lead-acid Bank

[Jay]

I agree with John

A pretty simple fix is to install a relay on the AC side controlled by the AUX of the inverter.

Have had to manually restart the batteries.  Problem only occurs if generator doesn’t start as programmed or manually started.  I install an iota 48v charger wired into the dc bus to jump start the system in worst case scenario where charge controllers are also shut down and generator can feed in bypass mode to provide a hot outlet for the IOTA.  The IOTA charger also serves as a small backup generator input pathway without having to change any charger settings in the inverter.

I'd like to offer them a Li option, but they have a suite of older electronics and I'm writing to ask the list if anyone feels like they've settled on a Li brand that works well with pre-Li electronics.  Glad for any suggestions.  Thanks in advance!
