More Solar In, More Money Out
Smart energy starts with capturing every ray. Five independent MPPT trackers handle complex rooftop layouts and mixed orientations, while up to 200% PV oversizing lets you install more panels than rated — turning early mornings, late afternoons, and shaded strings into real kilowatt-hours. With dual 100A battery inputs, you're free to expand storage gradually, mixing existing and new battery banks rather than replacing everything at once.
5 MPPTs: More flexible sloar panel layouts
200% PV Oversizing: Make the most of your roof
2×100A Dual Battery Inputs: Mix, Match & Expand with Ease
Always On, Built to Endure
Backup that doesn't blink. 0 ms seamless on-grid/off-grid switching keeps critical loads online the instant the grid drops, while the motor-friendly design confidently starts pumps, compressors, and other high-inrush equipment without tripping. Generator peak shaving automatically trims demand spikes and fuel consumption.
0 ms Seamless Switching (under grid open-circuit conditions): UPS-Level Backup, Zero Break
Motor-Friendly Inrush Handling: Starts More, Powers Everything
Generator Peak Shaving: Run smarter. Burn less fuel
