Review on Efficient 20A Solar Charge Controller with Adjustable LCD Display for 12V/24V Solar Panel Battery System, Intelligent Regulator featuring Dual USB Ports by James Small

I have been monitoring the solar charging system (using 2 charge controllers for the whole system) for several days and it is working very well. I am using a 1 x 100w solar panel to charge 2 battery systems. I am charging a 12v RV chassis battery (controlled by a charge controller) and 2 x 6v RV batteries (connected in parallel to get 12v) (controlled by a second charge controller). The chassis battery finished charging this morning as it was fully charged and thus provided a full charge for the house batteries which are now also almost fully charged. So the combination with a 100 watt solar panel and two individually controllable battery and charge controllers works great and I am very happy with the purchase. Also the customer service from the seller is excellent as they responded in a timely manner and with good detail to help.
