About The 12KW System

The off grid solar power systems SGR-12K20E addresses the requirements of larger off-grid residential and light commercial applications — the 12KW single-inverter split phase architecture delivering 120/240V output compatible with standard North American electrical systems. The 25.6KWH LiFePO4 battery bank provides more than one full day of average household energy autonomy from storage alone — with the 12-panel solar array generating approximately 20KWH daily to maintain battery charge and power loads simultaneously under typical 4-hour peak sun conditions.

The system is designed for straightforward expansion — additional batteries panels and compatible inverters can be added at any point as energy requirements grow without modifying the existing system architecture.

Off Grid Solar Inverter

The off grid solar inverter in the SGR-12K20E is a single 12000W 48VDC 120/240VAC unit — one of the most capable single-unit off-grid inverters available in the residential solar kit market. The split phase output enables direct connection to a standard North American load centre — powering both 120V and 240V loads including HVAC units well pumps workshop equipment and all standard household appliances without requiring an additional transformer or phase-splitting device.

Key off grid solar inverter capabilities:

• 12000W Continuous Output — handles high simultaneous load combinations without load shedding
• 48V Battery Interface — efficient low-loss DC connection to the LiFePO4 battery bank
• 120/240V Split Phase — standard North American electrical system compatibility
• MPPT Integration — works alongside the dual 100A MPPT charge controllers for optimised solar harvest
