Today solar batteries remain the most sustainable option for electricity storage and the environment. When used correctly, you undoubtedly reap multiple advantages. However, like any other product, you will face the demerits that arise during use. This article will find the four common problems you will meet with your solar batteries and the best ways to resolve them.

Faulty Solar Panel

The apparent solar battery charging problems arise from your broken solar panel. That makes your unit unable to generate enough voltage or power to charge your battery. A faulty controller can contribute to the underlying problems of this faster power drain. You can avoid this issue by ensuring you never store a fully discharged battery. You can likewise prevent internal damages by determining the best time to recharge and remove your solar batteries for an extended life cycle while saving many dollars.

Faulty Battery

Sometimes you get a faulty battery pack making it necessary to replace the unit immediately. Without doing this, you will always have low voltage leaving your battery out of power and remaining idle over time. Of course, charging your battery using the solar unit will be more challenging. So you must check the voltages and then use the current charger to fill it up. You can include a balancer to protect your batteries and ensure you have more extended functionality.

Solar Battery Short Circuit

The battery current is drawn from the unit when you have not connected your load and battery. Therefore, you will be experiencing discharge that may be considerably depleted. Over-discharging reduces the cells’ voltage, thereby cutting the power supply. You can use the over-charging protection to program your drop in cell voltage with a preset output threshold. Sometimes, over-discharge precedes the full cell discharge, especially when the load consumes exceptionally high power. However, the bag may not adequately induce the protection required against the short circuit.

Broken Solar Charge Controller

Sometimes the solar battery fails to charge despite being advanced or new. This common issue on the solar controller, especially when made from poor quality material, leaves your battery uncharged. In addition, your charge regulator can be broken, calling for a replacement. You can perform some battery treatments per the instructions, including repairing the damaged device to avoid an open circuit. In another scenario, you can easily set your unit where it receives more sunlight. Or maybe you can level up your series by boosting the number of photovoltaic series to avoid voltage mismatch.

Wrong System Setup

When you have not correctly set up your Charge Controller, Solar Panel, and Battery, your system will be non-functional. Directly connecting your panels to the batteries is improper and interferes with the negative and positive pole connections. Another critical element in the mismatch and wrong setup can stem from the environmental aspect. Your solar batteries will fail to work well without adequate sunlight or extreme weather. Installing your solar panels near a tree shade lowers your voltage, thereby reducing the capacity to charge.


Solar panels are a huge home or office investment that becomes very frustrating when the batteries are not charging. Fortunately, you can resolve your solar battery charging problems by correctly diagnosing them to determine the reasons causing the issues. Fixing the problem immediately prevent your future problems with faulty batteries, solar panel, and other equipment. Overall, properly caring for your unit and properly knowing the charging mechanism is the easiest way to resolve such an issue.
