TESTIMONIALS
Customer Reviews
I got this solar panel kit to keep my RV batteries charged. Easy to set up, almost like just plugging it in and letting it do its thing. I was skeptical at first, especially for my battery that powers everything from lights to the radio, but it hasn’t needed a charge since I hooked up the system a month ago. Ran into a bit of a snag with the control panel not being waterproof, but that was a quick fix. It’s been great for keeping my battery topped up without any fuss. Definitely made me a fan of solar energy.
Alex Sterling, Flagstaff, Arizona
Ever since I hooked up this solar panel, my remote work life has transformed. Living where power cuts are the norm, this panel has been a lifesaver, charging my inverter batteries with the abundant sunshine we get. It’s been seamless. My office stays powered, and my batteries get their sunbath, keeping everything running without a hitch. Plus, saying goodbye to my inverter’s electric charger has been kind to my wallet. The setup was easy, and seeing those voltage numbers stay steady is the reassurance I need.

How do solar chargers work?
Solar chargers use panels made of crystalline silicon to convert sunlight into electrical energy. The efficiency of this conversion depends on the installation location, sunlight intensity, and exposure duration. The stronger the sunlight, the better the charging performance. On a cloudy day, you might be surprised to still get enough power for a charge.
Does the solar panel have a built-in battery?
No, the solar panel does not contain a built-in battery. It uses materials with a high photoelectric conversion rate for efficient sunlight absorption and conversion.
Why is battery maintenance important?
Maintaining the battery is crucial because batteries naturally discharge over time, even when unused. This discharge can shorten the battery’s lifespan. Using solar panels helps keep the battery fully charged and prevent damage from natural loss.
Where can the solar panel system be used, and with what types of batteries?
The system is versatile and can be used with various vehicles and devices, including cars, trucks, boats, motorcycles, RVs, gate openers, water pumps, electric fences, lawnmowers, trailers, tractors, e-bikes, pick-up vehicles, golf carts, snowmobiles. Solperk’s solar systems are designed to keep 12/24V rechargeable batteries charged.
What is the purpose of the charge controller included with the Solperk solar panel system?
The charge controller serves as a converter that changes the solar energy from the panel into DC electricity suitable for charging batteries or powering devices. It acts as an intermediary between the solar panel and the battery/load, regulating the charging process. You connect the solar panel to this box and then the box to your battery. The controller ensures your battery is charged efficiently without the risk of overcharging.
Does the controller prevent battery overcharging?
Yes, the solar panel kit includes an intelligent controller with an advanced PWM algorithm. It protects against under/over voltage, output overload, short circuit, and anti-back connect, ensuring the battery is not overcharged.
How does the charge controller manage voltage?
The charger is designed to stop charging around 14.2 volts and resumes once the battery level drops to 12.8-12.9 volts. This is a routine operation to prevent overcharging, not a defect.
What are the installation steps for the Solperk solar panel system?
- Connect loads to the controller.
- Connect the battery to the controller first, ensuring the middle light turns on.
- Lastly, connect the solar panel to the charge controller.
The system is designed for easy use with plug-and-play functionality and pre-paired connectors, requiring no additional setup.
For optimal sunlight exposure, install the solar panel outside facing south. This orientation ensures the greatest amount of sunlight hits the panel.
How can I tell if my Solperk solar panel is charging or fully charged?
On your charge controller, you’ll find a couple of indicator lights: red lights signify charging, and green lights indicate a full charge. This visual feedback helps you monitor the charging process and battery status at a glance.
What does it mean when both the red and green lights are on?
When both the red and green lights are illuminated, it typically indicates a full charge. However, suppose you’re charging a battery simultaneously (e.g., connected to a power device). In that case, it may show both lights because the battery could charge and discharge simultaneously. This condition is normal and indicates the system is working as intended.
When I connect it to the battery, my charge controller’s lights turn off. What could be wrong?
If both lights go off upon connecting to the battery, ensure your setup is correct. Follow the installation steps closely, especially ensuring the solar panel faces south or southwest for optimal sunlight exposure. If there are still no lights in direct sunlight, it could indicate an issue with the battery condition (defective or excessively drained) or a connection problem.
Can the Solperk solar panel system be used to power small appliances?
Yes, the Solperk system can power various small devices and appliances beyond just charging batteries. For instance, it’s perfect for running heated lamps in chicken coops or similar setups where solar power is a practical solution.
Can the solar panel be mounted vertically, with the long side down?
Yes, the solar panel can be mounted in any direction, including with the long side down, to accommodate space constraints, such as on the side of a pontoon boat.
Can I disconnect the solar panel and leave the controller connected?
Yes. It’s possible to leave the panel mounted and disconnect it from the controller when needed. For example, if the panel is in a truck bed, it can be unplugged and stored elsewhere when the truck is in use. This method also works well with RVs, allowing the panel to be connected or disconnected based on travel plans while the controller stays attached to the battery.
Is it safe to constantly connect the solar panel system to a car battery, even when starting the engine?
Connecting the solar panel system directly to a car battery is safe, even when starting the engine. The controller is designed with a protection function to handle the higher current during engine starts. However, constant connection is not recommended to extend the controller’s lifespan.
Can one solar panel charge multiple RV batteries?
Yes, a single solar panel can charge two 12V RV batteries if connected in parallel. Charging is possible but slower if batteries are wired in series.
What is the length of the leads included with the solar panel system?
The solar panel cable is 78 inches long. The wires for alligator clips and O-rings are about 42 inches, and the controller cable is 22.8 inches.
