And I also second the suggestion you upgrade to a pure sine wave inverter. Mod sine can play merry hell with some devices, including charger/PSUs.

They do charge up 13.5 v and drop to 12.5v ,the most time I would use the system would be about 4 to 5 hours a night (not every night) and nothing is running during the day .What size pure sine wave inverter would I need to run the laptop because I think the type of inverter I am using may be the problem.
