Bifacial PV modules
630–650 W, up to 23.25% efficiency, world-class crystalline silicon cells
Home / Micro-grid & Energy Storage
Wind + Solar + Storage + Genset Micro-grids
Turn-key hybrid power systems with <10 ms on/off-grid switching and intelligent EMS — green, economical and dependable, from a single home to an entire island.
How it works
Renewables first, genset as firm backup
The EMS schedules wind and solar first, cycles the battery for stability, and only calls the genset (or grid) when needed — minimising fuel cost without ever risking supply.
