Review on Efficient 50W Solar Panel Kit with Upgraded Charge Controller – SUNER POWER Mono Crystalline Panels, Waterproof, and Versatile 12V Solar System for Car, RV, Marine, Boat, Trailer, Off-Grid Applications by Wei Fan

Pros: The panel has a nice aluminum frame, the voltage regulator looks nice and everything came ready to go with SAE solar connectors. Cons: The documentation was written in Chinglish. Bad mix of Chinese and English, hard to understand at times. The 3 status LEDs on the voltage regulator were placed pointlessly. IE: loading = red. The worst thing was that the solar panel was defective when delivered. This is the third solar panel I've bought to charge RV batteries and I always use my VOM to measure the DC voltage from the panel to see if the panel is working and if it has enough voltage to run the 12v Charge Trojan battery with Deep Cycle. .
