Product Introduction

This Rack Type Solar Deep Cycle Battery (Model: DM48-200R) is a LiFePO4 (Lithium Iron Phosphate) battery tailored for solar energy storage systems. Its working principle revolves around storing surplus electricity generated by photovoltaic (PV) systems during periods of sufficient sunlight (e.g., daytime, sunny conditions) and discharging it when solar power output is intermittent (e.g., nighttime, cloudy days). It relies on the electrochemical reactions of lithium iron phosphate cells to enable repeated charge-discharge cycles, thereby solving the intermittency issue of solar energy and ensuring stable energy supply.
