RE: battery to inverter wiring
Cabling is your bottleneck, a very common problem that causes grief for the poor 2000w inverter…Early on, I learned this the hard way, but now likely a bit overkill at 0004, 3’ with silver soldered and crimped copper lugs, but no more inverter alarms!!
3 tons
Got it. Thanks all.

RE: battery to inverter wiring
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.
I built the wiring 20 years ago without a large inverter in mind. The price of flexible welding cable has jumped a bunch. Just was quoted $6.89 a foot for 0/2 flexible! I will ponder the options and do whatever makes sense. Thanks again.

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 the inverter to the first pair of batteries and they are less than 3 feet in length. They are wired to the nearest pair. The batteries are connected with #2 awg cables. Given the price of flexible copper welding cable I am reluctant to build new cables for the batteries unless I know it is going to make a big difference. If we really need the microwave, I can fire up the Honda but I would like to be getting the 2000 watts off the inverter.
(I am also toying with getting an inverter microwave to run at lower power as an alternative.)
