The POM hybrid inverter efficiently converts DC electricity generated by photovoltaic (PV) panels into AC for household consumption. It also facilitates bidirectional power flow, enabling energy storage in a lithium ferro phosphate (LFP) battery system. During periods of high solar production, the inverter directs excess energy to charge the battery or export it to the grid. When solar output is low, it draws electricity from the grid to recharge the battery, ensuring a stable power supply.
Equipped with maximum power point trackers (MPPT), the inverters optimize energy capture by adjusting voltage to suit varying environmental conditions, enhancing battery charging efficiency. The 5 kW and 10 kW models support parallel operation, allowing up to eight units to work together to handle increased energy demands.
The inverters achieve high DC-to-AC conversion efficiencies: 94% for the 3 kW model and 98% for the 5 kW and 10 kW models. They support a maximum PV input voltage of 500 V DC, with MPPT voltage ranges of 120 V to 500 V DC for the 3 kW and 5 kW units, and 90 V to 500 V DC for the 10 kW unit.
Additional features include an automatic restart function for lithium batteries, customizable charging voltages for PV and grid inputs to accommodate diverse battery types, and reverse-connection protection with a fuse switch. The system can also operate without a battery when necessary, offering flexibility for different setups.
In terms of size, the 3 kW and 5 kW inverters measure 490 mm × 312 mm × 125 mm, while the 10 kW model is slightly larger at 571 mm × 571 mm × 148 mm.
