What happens if a battery reaches a full capacity?

Any excess energy produced once the battery reaches capacity is returned to the grid, and you’ll see a reduction or credit on your next power bill. What should you do if your batteries regularly become full?

What happens when a battery is fully charged?

When a battery is fully charged, you could simply allow the excess power to discharge, wasting the produced power and potentially damaging your battery over time. To prevent this, you can use a charge controller, which is a voltage-sensitive relay that activates only when the battery is fully charged.

How does a battery store energy?

Batteries store electrical energy on their internal plates in the form of a chemical charge, and once fully charged, an ideal battery could store this potential energy indefinitely until released through an externally connected load.

What happens if a solar battery is overcharged?

When solar batteries are full, the battery has used up all its capacity, which means no more solar energy from the panels can be stored. In this case, overcharging has the potential to damage the battery, which is when the inverter and the charge controller begin to play their parts. They handle the excess energy in the following ways:

What happens to extra energy when batteries are full?

When batteries are full, the simplest way to use the extra energy you generate is just to have your system connected to the grid. This means that instead of storing extra energy you generate in a battery, you’ll simply send it off to the grid. Your power company will usually pay you a small amount for the energy you export.

Why does a solar battery reach maximum capacity?

The reason a solar battery reaches maximum capacity is pretty simple and transparent. It could be because solar panels produce more energy than you consume daily. Other reasons lie behind are solar panel’s efficiency, system size, weather conditions, and geographical location.
