On Off Grid Hybrid Solar Inverter
Off-grid and on-grid hybrid solar inverter 4K/5K, smart solar energy storage system to maximize self-use of solar power. Batteries are used to store the surplus energy generated by solar panels. Surplus energy will be exported into the grid when batteries are fully charged and system self-consumption has been achieved. Batteries will power the AC load after sunset, if the battery capacity is insufficient for self-use, electricity will be supplied from the grid.
Off Grid and On Grid 4kW 5kW Hybrid Solar Inverter
Solar hybrid inverters 4K/5K energy storage inverters are used in residential PV energy storage systems, with peak-cutting and valley-filling functions to maximize the use of PV power generation while achieving the goal of saving residential electricity bills. In addition, different working modes can be set as per different customer needs. They are compatible with lead-acid batteries and lithium batteries and can provide uninterrupted power for important load devices with a back-up power supply.
*WHAT IS A SOLAR HYBRID INVERTER?
Solar hybrid inverter is a hybrid between the traditional on-grid inverter and off-gird inverters. During normal operation the hybrid inverter synchronizes with your mains utility power and supplements your power usage using the solar power during the day. In addition to this cost saving during daylight hours, batteries are used to supplement your usage during the evening hours.
The solar hybrid inverter will first use the solar power, if the demand exceeds the solar power it will supplement it with mains utility power. If the solar power exceeds the power demand the excess power is used to charge batteries. If the batteries are fully charged the excess power can be fed back into the grid.
