Hey Burg, I meant inverter, clouds, and everything combined will give you a 25% efficiency hit. I have a new, small (1500w)inverter, and it supposedly gets me ~90% efficiency.
Just a warning about Batteries. When choosing battery capacity, figure 5X more capacity (in Ah) than needed for your planned running hours. That's because batteries die quickly if ran down below 80% of their capacity. Golf car batteries will hold up pretty good down to 50%, but will last 3x longer if not discharged below 80%. I guess a common trolling motor battery will last about a month if it's drawn down below 25% every night, and about 2 years if drawn down no lower than 80%.
