How I wired the Harbor Freight Solar Panel System power into my house from my shop and made it simple to use and to monitor our power usage from inside the house. Our system has 4 panels for 60 watts since the controller will handle 4 amps. I wanted to keep the cord run from the panels to the inverter short so there would be very little power lost from the panels. I came up with this system and it has worked out great. Maybe this will give you some ideals on what you could set up for you and your needs. We really like our system and use it every day. It’s an amazing feeling to know if the grid goes down we still have power.
