Benefits & Tips
- Keep essential loads running: use the pure sine wave output to safely power sensitive electronics like computers, routers, and entertainment systems even during grid outages.
- Optimize solar charging: leverage the built-in MPPT controller (60VDC–450VDC MPPT range) to adapt to different array configurations and maximize energy harvest throughout the day.
- Flexibility for hybrids: configure AC and solar charger priority to favor solar when available, and gracefully switch to grid or generator power as needed.
