  • How to charge the photovoltaic panel when the battery is full

    How to charge the photovoltaic panel when the battery is full

    As soon as a solar battery reaches full charge, the inverter and charge controller must step in to mitigate risks by handling excess power. They can do this in three ways: push it back into the panels for power loss, back into the grid for credits, or force a dump load. If the system is not tied to the grid, excess energy production would generally cause the charge controller to cease. When your solar charger detects a full battery, it stops sending power to prevent overcharging—but there's much more happening behind the scenes. In this scenario, a delicate balance is required to prevent overcharging, which could harm the battery.
