Hello...1/2 HP = 9.8 amp . Would need 170 watt panel , 200 watt inverter , 30amp charge controller and 100 Ah AGM battery. ...

You need to look at the startup surge of the pump. No way will a 200W inverter and 100AH battery handle that.

I put what you're trying to do in the same catagory as trying to convert a gasoline engine over to diesel fuel. It can be done but isn't worth it when buying a diesel to begin with would be cheaper, last longer, and be more dependable.

Hello,

I live in East Texas.

I have a Shur-Dri 1/2 HP Jet Tank Sysytem (above ground) with a 7-gallon pressure tank. No holding tank.

It has 115v or 240v option. I am using 115v.

Water line is approx. 25ft below ground. I am pumping 250ft in 1" pipe to our home.

I want to do away with the line and power pole and covert to a off grid solar power with batteries.
I have done some research but want to understand if my estimates are correct for what i need.

1/2 HP = 9.8 amp . Would need 170 watt panel , 200 watt inverter , 30amp charge controller and 100 Ah AGM battery.

Please, feel free to correct my estimates and give helpful advice.
