- Delivery & return
Hybrid All-in-One — Combines solar PV inverter, battery charger/discharger, and grid export/import logic in a single device; suitable for self-consumption, storage, backup (EPS) or grid-tie use.
3 Independent MPPT Inputs — Allows multiple PV strings (on different roof orientations or tilts) to be connected and optimally tracked for maximum yield.
High DC Oversize & Flexibility — Designed to accept a significantly larger PV array than nominal AC output; offering flexibility to oversize PV for battery charging or export.
Smart Monitoring & Easy Integration — Supports remote monitoring via app/web portal (cloud platform), easy plug-and-play installation with built-in protections, and compatibility with high-voltage battery systems for future scalability.
