Typical applications

Large residential — whole home supply including air conditioning, borehole pumps and electric cooking. C
ommercial premises — retail, hospitality, clinics and offices with substantial continuous load.
Institutions — schools, health centres and places of worship with critical and non-critical circuits.
Generator hybridisation — cuts diesel consumption by prioritising solar and battery supply.

Key Features

Three operating modes — grid-tie, off-grid and hybrid, selectable on site.
Dual PV input — two independent MPPT trackers for split or differently oriented arrays.
160 A MPPT solar charger, the highest charge current in the SATTE range.
Dual load output — separate main and second load terminals with automatic non-essential load shedding.
Grid-tie, off-grid and hybrid modes; pure sine wave, power factor > 0.99. Wi-Fi and GPRS remote monitoring for iOS and Android.
Builtin automatic lithium battery activation and dedicated BMS communication port.
Runs with or without a battery; anti-dust kit and one-key factory reset fitted.
