Hoymiles HIT-8L-G3 Hybrid Inverter 3-phase LV

The Hoymiles HIT-8L-G3 hybrid inverter is a three-phase inverter with a rated power of 8000 W, designed to work with photovoltaic installations and energy storage systems. It allows operation in energy management modes (self-consumption, economic, emergency, peak shaving, and time-of-use tariffs) and remote monitoring via the S-Miles Cloud.

Manufacturer

Hoymiles Power Electronics Inc. produces the HIT-(5-20)L-G3 series — high-performance, three-phase hybrid inverters characterized by high reliability and advanced EMS functions. Devices in this series support integration with energy management systems and allow for system expansion through parallel connection of inverters.
