Solar freezers like the Bona Solar Freezer are designed to offer off-grid cooling using solar energy. However, one of the most frustrating issues users face is the battery not charging properly. This problem can disrupt cooling, spoil stored food, and reduce the freezer’s overall efficiency.
Below, we explore the key causes, troubleshooting steps, and recommended solutions to fix the battery charging issue in your Bona solar freezer.
If the panel isn’t delivering power correctly, the battery won’t charge. Check for:
✅ Solution: Re-secure all wiring, clean connectors, and reposition the panel to get maximum sunlight (ideally 4-6 hours daily).
Over time, solar batteries can degrade and lose their ability to hold a charge.
✅ Solution: Inspect the battery’s health. If it’s swollen, leaking, or over 3 years old, consider replacing it with a compatible deep-cycle solar battery.
The charge controller regulates power from the solar panel to the battery. A malfunctioning unit may overcharge or undercharge the battery.
✅ Solution: Test the controller using a multimeter. If it's defective, replace it with a good-quality MPPT or PWM solar charge controller.
If you’re overloading the freezer or connecting additional devices to the battery, it may drain faster than it charges.
✅ Solution: Avoid using other devices with the freezer’s power supply. Ensure only the freezer is connected to the battery for best performance.
Dust on the panel or poor sunlight due to the weather can reduce charging efficiency.
✅ Solution: Clean your solar panels weekly and install them in a location with optimal sun exposure.
The Bona Solar Freezer is a reliable off-grid solution — but like any solar appliance, it needs proper maintenance. If your battery isn’t charging, follow the troubleshooting steps above to get back to efficient operation.
