Installed in my caravan while working as described. The inverter works with my 10,000 BTU dual inverter LG AC window unit. I also tested it on my 1500w heat gun with no problems. The inverter is not working with my old 14kBtu portable AC. I think it could be due to the low voltage cutoff and lack of soft start on the AC unit. The gear shift and the three-stage charger also work perfectly. I would like the seller to post the remote control or the part number for the remote control. To update! I emailed the seller about the remote control, they gave me a link to the remote control.
