Typical Applications
Detached houses, apartment blocks and industrial rooftops feeding power into the utility grid under net-metering or self-consumption schemes.
Common Pain Points We Solve
- High electricity bills: over 97% efficiency and 99% MPPT tracking convert the maximum share of sunshine into bill savings.
- Complex or shaded roofs: a wide MPPT voltage window keeps yield high on difficult roofs and cloudy days.
- Outdoor mounting worries: the IP65-rated enclosure mounts outside without extra shelter or cost.
- Silent failures: RS485/WiFi monitoring sends fault alarms to your phone, and the 5-year warranty is backed by the factory.
