Just finished my inverter install and am testing capacity with some disappointment.. I'm trying to run microwave even for a few seconds before I get a low voltage alarm and shutdown. My battery bank (2-6v 255Ah LA Duracell in series) is currently a joke but am upgrading soon. My settings in the inverter are to shutdown at 12.50v which it hits almost instantly after starting the microwave even with 100% battery SOC,.. (can I set these limits lower?) I realize this is discharging the batteries at almost 1C and perhaps the batteries cannot take it but I didn't see a discharge limit in the charge specs Deka sent me so am not sure. All cables are to the inverter are 4/0 and returning to battery (shunt first) are 4/0 and are about 6' long, my main chassis ground is only 2guage though but would this play a factor if to/from inverter goes straight to battery? Ive attached the battery specs below. And should say I have 565 watts on the roof which don't seem to be offsetting much when trying the microwave.
Any thoughts are greatly appreciated.
