Photovoltaic battery working principle picture
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
Other reasons batteries are used in PV systems are to operate the PV array near its maximum power point, to power electrical loads at stable voltages, and to supply surge currents to electrical loads and inverters. In most cases, a battery charge controller is used in these systems to protect the battery from overcharge and overdischarge.
