Safety certified for North American electrical standards. Essential for permits, utility interconnection, and home insurance.
Start charging earlier, stop later. Low 40V startup captures morning/evening sun and works on cloudy days. High 500V input reduces cable costs.
Run loads directly from solar + grid. No battery needed for daytime power. Perfect for budget-conscious homeowners.
Seamless blackout protection. Computers, TVs, and routers stay on during grid failure. UPS-level transfer time.
RS485 / optional WiFi. Monitor solar harvest, battery status, and system health from your smartphone.
Scale from 3.3KW to 19.8KW (3 units) or 37.8KW (6 units of 6.3KW model). Perfect for growing energy needs.
The HFU Series is a high-frequency hybrid solar inverter designed specifically for the Americas market. It supports single-phase input and output with user-selectable voltages (105V/110V/115V/120Vac), making it compatible with US, Canadian, and Latin American electrical standards.
This all-in-one solution combines an inverter, MPPT solar charge controller, and battery charger into a single compact unit. Whether you want a grid-tied system to reduce electricity bills, an off-grid system for remote locations, or a battery backup system for outage protection, the HFU Series delivers.

Yes. The HFU series carries UL certification (UL 1741) , which is the standard safety requirement for grid-tied and off-grid solar inverters in the United States. This certification is essential for obtaining building permits, passing utility interconnection inspections, and ensuring compliance with local electrical codes. It also satisfies requirements for most home insurance policies.
Yes. The HFU series supports "battery-less" or "grid-tied" operation. In this mode, the inverter powers your home loads directly from solar panels during the day. If solar power is insufficient, it seamlessly supplements from the grid. This significantly lowers the initial investment cost – you can start saving on electricity bills with zero battery purchase. Batteries can always be added later for backup power and nighttime self-consumption.
Most competing inverters in this class require 90V or higher to start charging. Our 40V startup means your system begins generating power earlier in the morning and continues later in the evening. It also performs significantly better on cloudy or overcast days. Over a full year, this lower threshold can add 5-10% more energy harvest compared to competitors – a meaningful difference in overall system ROI.
