The Deye SUN-12K-SG02LP1-EU-AM3-P is a high-performance 12kW single-phase hybrid inverter designed for larger homes, offices, commercial facilities, and demanding solar installations.

Built around a low-voltage 48V battery architecture, the inverter works with compatible LiFePO₄ and other supported battery technologies, making it an excellent choice for systems requiring substantial energy storage. It intelligently manages energy from solar panels, batteries, the utility grid, and a backup generator to deliver reliable power throughout the day.

With advanced MPPT solar tracking, the SUN-12K-SG02LP1-EU-AM3-P efficiently extracts available energy from the PV array, even when solar conditions change. Excess solar energy can be directed toward battery charging, allowing stored energy to be used at night or during grid outages.

The inverter also supports on-grid and off-grid operation, providing flexibility for installations where grid availability is unreliable. Its fast transfer capability helps maintain power to essential loads when the grid fails.

For larger energy requirements, the inverter can also be configured as part of a scalable system using supported parallel and system-control configurations.

Recommended Solar Panel Configuration

When paired with LONGi Hi-MO 7 615W bifacial panels, the number of panels can be selected according to the site’s daytime energy demand.

Basic daytime use is suitable for homes and businesses with moderate daytime loads such as refrigerators, freezers, lighting, televisions, computers and a limited number of air conditioners.

Heavy daytime use is recommended where there are multiple air conditioners, pumps, commercial equipment, office loads or other high daytime consumption.

Final panel quantity and string configuration must always be checked against the inverter’s maximum PV input voltage, MPPT voltage range, maximum PV current and allowable PV oversizing.
