The sunlight shines on the solar module during the day, so that the solar cell module generates a DC voltage of a certain magnitude, converts the light energy into electric energy, and then transmits it to the intelligent controller. After the overcharge protection of the intelligent controller, the electric energy from the solar module It is sent to the battery for storage; and storage requires a battery. The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

For solar energy storage batteries that are newly installed or charged for the first time after refurbishment, charge them for a longer period of time. For initial charging, they should be charged at a current of 1/10 of the rated capacity. Before installation, it is necessary to measure whether the battery is sufficient. If the power is insufficient, please charge the battery for more than 8-16 hours in a sunny place or use AC power to fully charge the battery first. Over-discharge charging should be strictly avoided. When using AC power to charge normally, it is best to use the grading charging method, that is, use a constant current equalizing charge with a larger current in the early stage of charging, and then use the conventional constant voltage floating charging method after charging to the equalizing voltage and constant voltage for a certain period of time.
