Sunpal lead acid solar battery and energy storage devices are indispensable devices for storing electrical energy in off-grid photovoltaic power generation systems and grid-connected photovoltaic power generation systems with energy storage. Their main function is to store the electrical energy of the photovoltaic power generation system, and when the amount of sunlight is insufficient, at night As well as supplying power to the load in an emergency state or using stored electric energy in the grid-connected system to avoid valley peak shaving and reduce the impact on the grid,Lead-acid batteries require proper care and maintenance to extend their service life.
