battery to inverter wiring
I have a 2000 watt inverter charger running off 4 GCU 6 volt, fully charged golf cart batteries. High load appliances like the microwave quickly cause a low voltage overload. I have 2/0 cables from...

Check each cable voltage end to end under load. Load test your batteries as they could be weak. Unbalanced loading causes more usage on the nearest pair and shorter life.
Thanks for your replies. Yes, I regularly check the cells with a hydrometer and all are good. The voltage at the inverter drops to 11.8 which is where it will drop off line
Also can you lower the cutoff voltage on the inverter?
