Dennis,
If you were pulling 830 watts from the inverter, that’s 69 amps @ 12 volts! How big a fuse do you have on your inverter? My 600 watt inverter uses a 50 amp fuse.

Couple boats had lots of lights and generator on deck. Couple years ago I decorated Touche' with a bunch of light strings. We probably had 15-20 strings of lights. We have about half incandescent and half LED strings. I'd added up the wattages on the boxes for the LED lights and estimated wattage's for the incandescents. Came to around 700 watts. Touche' has a 1000 watt inverter. When we fired everything up, the inverter was showing around 830 watts. At 120 VAC that's about 7 amps. In the parade we were moving at idle speed. I was constantly monitoring the 12 VDC system on my instruments. RPM's weren't enough to maintain voltage on the batteries. Every now and then I shifted to neutral and revved the engine to boost amperage. We did fine over the hour long parade using that technique. Do the research and add up the wattage's. Try to use exclusively LED lights, 12 VDC if you can find them. Convert to amps and remember that your alternator doesn't generate much amperage at low RPM's. Dennis C.
