FLK off/on-grid Series
800W-1200W Micro Inverters

Fullink New Energy's FLK 800-1200w Microinverter offers a new ideal solution for home storage PV system linked to 5KWH-20KWH storage battery, which is a dual power micro inverter. Like other common microinverters, FLK off/on-grid Series Microinverter has a peak efficiency of 95.5% and a nominal maximum power point tracking (MPPT) efficiency of 99.5%. That Functions for rapid shutdown and is able to operate at completely low voltage. And it is available as a single-phase (220V) and three-phase device(380V). Also it can be used with 60 and 72-cell designed modules and a power output of up to 2000W. Each microinverter can accommodate up to four PV modules with an output of 600W on each.

  •  Solar panels output voltage <60VDC, decrease the risk of an electrical fire.
  • One-panel match one MPPT, increase 5-15% power in production vs string inverters.
  • Keep each panel working individually, avoid the impact of partial shadows on the entire solar system.
  • Independently tracking each solar panel’s production, easy to identify each solar panel's  performance.
  • Flexible application can switch to off-grid mode to supply AC power to home devices.
  • Lightweight and compact with plug-and-play connectors, easy to install.
  • App monitors the running station anytime, anywhere.
