I am not familiar enough with the RT inverter/charger but what caused the inverter to shut off when the charge ports all disconnected?

The transfer relay only activates when the inverter is on. When the inverter is off it does nothing, no pass through, no battery charging, no inverting, nothing operates.

Looks good, does the BMS report accurate battery SOC or would it make sense to add a shunt and Victron Battery Meter to get SOC?

All true except in this case the warranty was simply a marketing tool unrelated to actual future costs for warranty coverage. It is pretty clear that EHGNA was not doing business in a financially...

Yes, the minus is not having inverted 120v power when the solar and GU chargers are providing more charge current than you are currently using and they get the batteries full. I guess you would get...

I assume so too, a 6 year warranty was a major marketing tool to convince owners to take a chance on Ecotreks. KS2 is not giving anything close to that on the ones they are now supplying and the...

In the ARV system there are only 2 of these Tyco relays so the parasitic drain is not very significant for the typical 800-1200 AH lithium systems they were installing. Reliability may have been the...

Won’t there be continuous charge currents greater than 100 amps from the GU when you only have on battery connected. With both online you could still get higher current when one gets full.
