Well you can upgrade any amp controller that's not expensive, but I'm testing with the stock unit.
I had a few panels delivered last week just need to find the time to install them.
I'm pretty confident I'll get 50+ miles out of the system.
My friend who is a solar guru, tested a cart going 8 mph shutting down the batteries and went several hours without batteries just solar.
Now I know you need to go faster than that but remember all the time your out it keeps charging.
I'll post pics and tests in the next few weeks when it's all together.
