SUNAPEX Flexible Solar Panel Kit For 12V
Battery Maintain & Trickle Charging

Note: Please make sure the polarity is right when connected to your battery to avoid shortcuts. Red wire is positive; Black wire is negative.

How to Clear the Charging Status of Solar Charger?

Solid blue–Receiving sunlight, output normal;
After connected to the battery and the red light is on, indicating that it is charging.
When fully charged, the green light will come on, at which time all three color LEDs will light up.
All light off means short circuit. Need check the polarity connection

ETFE Material-30% High Conversion Rate

The solar battery charger adopts ETFE material can collect sunlight from different angles, and the fine layout can make secondary use of sunlight refraction. The light transmission rate up to 95%, providing 30% high photoelectric conversion rate. And lifespan of 20 years.

Why do We Need a Solar Trickle Charger or Battery Maintainer?

Natural Battery Discharge—Ever left your car sitting for a while only to find a dead battery when you need it most? This is because the car battery will continue to discharge naturally even if the car is parking. Our solar battery charger prevents this by constantly topping up your battery, ensuring it’s ready to roll whenever you are.
Continuous Power Drain—Today’s vehicles are packed with over 30 electronics – control modules, alarms, anti-theft systems, and more. They all consume your battery power even when parked. With our solar panel charger, you’ll combat this power drain, guaranteeing your car is always ready for action.
Extend Battery Life—Your car battery’s lifespan depends on maintaining the right voltage. If a 12V battery dip too low can lead to sulfation, which is the main leading cause of battery failure. Our solar car charger keeps your battery voltage in the sweet spot, prolonging its life and saving you the cost of a replacement.

How to Choose the Right Solar Panel for Your Car?

Battery Condition—First of all, our solar panels are only suitable for trickle charging and maintaining 12V batteries, not suitable for batteries already dead. Please check your battery condition before use this solar trickle charger, if the use of the car battery is too long or aging, then even if the solar panel is charged, the battery may not be fully charged or the charging state may not be kept.
Power Output—The larger the power of the solar panel, the faster the charging speed. If the solar panel’s power is not enough to meet the needs of the car battery, the battery may not be fully charged even if it is exposed to sunlight all day. So please choose the right watts to match your battery.
Usage—If you use your car daily, a lower wattage panel may suffice to maintain your battery. For vehicles parked for extended periods, higher wattage panels (20W and above) provide better effect against battery drain. 30W is ideal for larger vehicles, like SUVs or RVs, or if you have several power-hungry devices to charge.
The upgraded built-in controller consumes no power at night.
