How to prevent overcharging a solar battery?
To prevent overcharging, using high-quality solar charge controllers that automatically regulate the charging process based on the battery’s status is essential. Additionally, regularly checking and calibrating the BMS ensures that it continues to function optimally.
Why does my solar battery discharge to the grid?
Solar battery discharge to the grid occurs for several reasons. Knowing these reasons helps you manage your solar system effectively. Your solar battery might not store enough energy if its capacity is too low. This limitation leads to energy overflow, resulting in discharge to the grid.
Can a faulty charge controller affect a solar system?
A faulty charge controller could lead to sudden voltage spikes or drops, affecting the battery internal charging system. The inverter is probably the most sensitive part of a solar system and problems with it could disrupt the battery charging capacity. Regardless what battery type you use, proper maintenance and use are essential.
Why is my solar system overcharging?
Overcharging is a common issue in solar systems, occurring when a battery receives more energy than it can store. This often results from a malfunction in the battery management system (BMS) or improper configuration. The excess energy leads to problems like overheating, gassing, and a shortened battery lifespan.
How does a grid-tied solar system work?
When this happens, your system compensates by discharging stored energy back to the grid to meet demand. In grid-tied solar systems, the excess energy produced by your solar panels gets funneled back into the grid when the battery reaches full capacity. This process prevents battery overcharging and helps stabilize the grid.
Do solar panels need a charge controller?
As many solar panel users will point out, using a charge controller is one of the best ways to prevent unexpected battery drain. A charge controller regulates the flow of power in the battery and prevents overheating, one of the main causes of power drain. There are two types of charge controllers, PWM and MPPT.

Why do the batteries just keep charging?
It looks like your SoC has drifted and is out of sync with battery voltage. Your charger must see 26.88V and continue charging to 28.4V regardless of the 100% SoC reading.
