I think it is time to replace the old inverter on my boat. It is the original installation of 1984. It takes a little bit of a load to get it to power up. I think it is a 2000 watt rating. Anyone recommend a manufacture and size to install. Have some money saved up and I think it would be a good investment. I am also trying to figure on what is best to hold my cups from falling over while in the microwave in a tossing sea..
