I would be interested to know a bit more about the installation, what are the battery cable sizes as your pulling a lot of amps, as a rule of thumb, if the battery leads get hot as this is a relatively short test then this is one reason why the voltage drops very quickly. Again are the batteries getting warm/hot, 2000watts is a big ask for so few batteries, but all said, an interesting video
185A I was pulling so had 35mm strapers and 25mm on a 200A fuse to the inverter. Nothing was hot apart from the inverter but the fans kick in and it has thermal protection.
Wouldn't mind a video up of you you set up the sollar power unit you have in your lock up ? By the way it was only 2 screws on the engine cover it was just muck and crud that held the rest on all cleaned up now. Although I would say it's a bad design on that engine cover with the sponge inside it. Honda need to think of another idea. I take it it stops vibration
Still running great I drained them down to 11.8v the other day by leaving my low wattage (135w) tube heater on for 2 days...but it's recovered back to 13.8v
