I've been doing some investigating of solar systems lately and it seems inverters are always a big question. And are to me too. Myself I don't know diddly squat about them, but from what I've read ,,a shine wave type is the best to get. I didn't happen to notice any spec for amperage's on that one you showed. It sounds like you're using some high draw stuff, so no doubt you'll need a commercial type, capable of handling high amperage draws by the sounds. But like I said I don't know shit about them!! But I do know about electrical systems and amperage draw is a big concern, and it sounds like start up amperage on the equipment you are using will be pretty high. Something to keep in mind. And don't be scared to go up a gauge or two on the wiring, cheap insurance against overheating and fires,,,plus efficiency.
I'd go to one of the web sites or a local solar distributor for more info. or to someone that does instals on this type stuff, they'll know. It sure could save you some aggravation of not getting the right stuff,,,,,or worse yet,,,,,,an electrical fire !!!!
