The kit works well except that the charge controller is the weakest (read cheapest) link. I have had two fail on me, same way each time. Batteries are charged, but it doesn't give any voltage to the load (ie opener). Other points to consider, directions and troubleshooting is pretty light for all components. A multimeter is a must.
Lot of things gave us problems installing it
I'm so glad we decided on this. Good Quality and perfect
The price was right. I received it very quickly. The product work well and I'm very pleased. Thank you!
