Gel battery are the most commonly used type of battery in photovoltaic systems, with a designed floating life up to 20 years. The solar gel battery is an improvement of the ordinary lead-acid battery with liquid electrolyte, replacing the sulfuric acid electrolyte with the colloidal electrolyte, which improves the safety, storage capacity, discharge performance and service life.
