Overview of Photovoltaic Off-grid Power SystemThe on-grid solar power system is composed of solar modules, inverters, generating electricity in the day time.The system nowadays becomes the most effective approach of large-scale solar power usage.

The off-grid solar power system consists of solar modules, batteries, controller and/or inverter. The system shall be confiured according to the loadings. This system could be installed where grid electricity is not accessible.Configuration of 10kW Off-grid Solar Power SystemComponentSizeQuantitySol

Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible energy storage.
