ROCKSOLAR 20A MPPT Solar Charge Controller

Great product

I used it to charge a lithium battery, and it's amazing and better than my previous older solar charge controller. however, you can set it for a lead acid battery also.

I’ve gone through several solar charge controllers that have failed to meet expectations. I’m running a 12V electric fence charger with a lead-acid (small tractor) battery. After tried many solar charger controller then I switch to this charge controller. I’ve had it in service for 2 weeks now with the same solar panel and battery as before and it has kept the battery perfectly charged. very happy with this product.

Had issues with the previous charge controller. This unit was recommended by my RV Builder. Works providing more charge power than the unit it replaces. Recommended.

Worked great, so didn't need any tech support or help. The installation process is so simple. highly recommended to anyone.
