GoodWe GW8K-ET PLUS+ Three Phase Hybrid Inverter 8kW 3PH 2MPPT

GoodWe GW8K-ET inverter - ET Series 5-10 kW - Three-phase inverter for energy storage

• The new ET Series from GoodWe - are three-phase high-voltage hybrid inverters, available in: 5 kW, 6.5 kW, 8 kW and 10 kW, designed for use with both the public grid and energy storage.
• The ET series not only enables increased energy independence, but also maximises the self-consumption of generated energy.
• Programmed battery discharge/charge control modes can be matched to time-based tariffs, further helping to reduce electricity bills.
• For maximum power output, the ET series allows the inverter to be overloaded on the AC side up to 110%, and for maximum energy efficiency when the grid is active and independence and safety in the event of disturbances or faults in power systems, the ET series has an uninterruptible power supply (UPS) function for inductive loads such as air conditioners, refrigerators with an automatic switching time of less than 10 milliseconds.
