SOLPERK 10A Solar Charge Controller Waterproof Solar Panel Controller 12V/24V PWM Solar Panel Battery Intelligent Regulator for RV Boat car ，with LED Display

a good replacement charge controller well made item

Inasmuch as my hunting vehicle sits at my camp a lot, I choose to put a solar panel up to keep the battery up. This waterproof charge controller fit the bill for that purpose, waterproof, easy to read display, great price, easy to hookup, and works great!!

I use the system to charge my trolling motor and main battery for my outboard. I switch back forth, but Solperk claims that the system can be used to charge two batteries simultaneously.

Better than the original unit that came with the panel. Only complaint is the cord remains short so if you have a Class A that requires some distance between the panel and the battery, this presents some challenges. Would be more secure and protected if I could mount the controller inside the engine compartment but the wire length prevents this.otherwise, the controller works as advertised.

Using for a 100w solar panel to keep trailer battery charged. Simple and efficient. Could use some digital readouts but still works good with the red and green light indicators. Well worth the inexpensive cost.

I’ve been running a 6.5 amp DC fan in the attic of my shed off of a 100 W solar panel all summer. I thought it would be a good idea to be able to charge my dirt bike battery as well so I bought this controller. For some reason the fan won’t run without the battery being connected. Connecting the battery makes the fan run but it surges running full on for not even two seconds before reducing to a whisper for a few seconds as the controller goes into “over discharge protection” after which the green full charge light for the battery will come on and the fan will then spin up to full speed only to immediately drop again into over discharge protection mode. This is a poorly thought out design. If the battery is at full charge the controller should continue to monitor the battery level and send power straight to the load device regardless of whether it’s connected to the battery or not. If the solar panel is not producing enough current to power the load only then should the battery come into play. This device is worthless to me for anything other than charging the battery.
