I have an as yet uninstalled growatt 12k low frequency inverter. I was planning on using the grid bypass function but after reading half a dozen threads on how to handle the neutral I'm having my doubts.
So I'm wondering if I can just run "off grid" but use an external battery charger running off grid power to keep my batteries from getting too low. I'm thinking of controlling it with a smart plug and home/solar assistant to turn on and off at certain states of charge or possibly when the loads are high relative to pv input.
Will this just unnecessary stress my batteries (30kwh lithium) and should I just get a different inverter instead?
