He meant the low voltage alarm that inverters have. Typically 11v for the alarm to sound, and 10.5v for the inverter to shut off.

11.6v alarm is quite high. Of course that would be as "seen" by the inverter at its end of the wires to the battery.

It is a modern inverter like most these days, not the old heavy type.

Yes, I was wondering if others are seeing the low voltage LUP(?) and hearing the squeal at 11.6V? It's essentially the battery voltage in my case as I recently upgraded to short 1/0 cable and heavy soldered lugs.

No, that's not a good price for solar in Canada.

I suppose not if you live close to a solar wholesaler, many don't and must factor in transport. Around here rv dealers still charge over 5$ a watt for panels. For many it is a good price.

Ouch. I paid ~$1/watt here around Toronto, Ontario, but they were the higher voltage type used in big installations and on houses, and I picked them up myself. An MPPT controller is required. Really wouldn't expect a good price from an RV dealer.

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.

Hmmm, good idea. Except my Cummins is so noisy!:(

If I'm running a heavy load, it's usually because it's too hot to cook inside, which usually means the sun is shining outside so the solar can provide load support. I was getting over 500W peak solar in a partially shady site in the Everglades. And that 950W for boiling water was to make Iced Coffee in the afternoon; solar probably provided a few hundred watts then.

The rest of the cooking is lower watts over a longer period of time which my 400Ah of batts can do. Once you get the water/stew/whatever heated up (we also use an induction hotplate), keeping it hot takes a lot less watts.

Thank you BFL13, for your kind answer, below :)

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.

As I posted earlier, mine ran my "700w" Danby MW that wants 1050w input, showing 1050w on overload, but after a few times the inverter went poof.

Maybe buy another as a spare during this sale, if you are going to keep doing that :)

Thanks good to know theres not much overload tolerance. Lucky it survived the Air conditioner test, IIRC the running amps are less then the 700 watt Microwave but the start up amp could have been a killer.
