Commercial AC-coupled Inverter (High Frequency)-30K/50K/60K

Product Model
LEG-30K / 50K / 60K-TL-P

Hybrid inverter converts the mains AC power into DC power to charge and store the battery. When the mains power is cut off, the DC power stored in the battery is transformed into mains AC power for small industrial and commercial loads.

Product Detail

Application Scenarios

AC-coupled inverter are used in the upgrading and transformation of completed photovoltaic power plants. Photovoltaic power generation (for example, when there is local restrictions on photovoltaic power generation to the grid) or photovoltaic power generation at low electricity prices can be stored first by adding AC-coupled inverter and battery packs, and then sell at night, at peak electricity prices or for load use. This can maximize the overall power generation revenue.
