I have a 1000 watt Xantrex ProWatt MSW inverter. It's off when not in use. There is a measurable draw if left on. There are three "modes", On, Off, and Standby. I change to Standby mode using a remote panel switch. The draw is much lower in Standby, but once my camping trip is done, the inverter is powered completely off. The inverter is small enough that I've never had to worry about the initial capacitor surge.
Tired Old Man, if possible, the panels should match. While mismatched panels can be wired together, it often doesn't make sense to do so.
