Can't really use anything bigger without upgrading my battery bank 'cause of voltage drop (short 1/0 cables are ok). This inverter starts whining at ~11.6V.
I currently still only have a single, 9 yr old G27 Interstate on my trailer and found that load supporting this 1000 watt Cdn Tire PSW inverter with my truck (running) solved that excessive voltage drop issue entirely. On battery alone the inverter runs my coffee maker without protest but the toaster does eventually draw voltage down to the point where the inverter will squeal ... still runs, but does squeal. If I plug the trailer's Bargman into the truck voltage never drops below 12.3 volts under load, if I connect the truck's battery directly to the camper battery with 4 gauge booster cables voltage never drops below 13.3 volts ... in either case the inverter handles the loads I present to it just fine. I'm thinking for next season I might just cut the booster cables to a shorter length and terminate them with Anderson connectors which I already have so I can quick connect the truck battery to the camper battery. I'll eventually have to replace this battery and will probably go with a couple of G31s or GC-2s but in the meantime load support with the truck seems to work just fine for the limited number of times I need it.
