Product Description
The UE SPI-8K-UP and SPI-10K-UP are powerful 48V hybrid inverters tailored for off-grid living, rural properties, and backup power systems in the US. Featuring UL1741 and FCC Class B certifications, they are fully compliant with North American electrical standards.
Each unit delivers clean pure sine wave output at 120/240V, supporting all common household appliances and even motor loads (up to 6HP). The system supports dual MPPT inputs, enabling 11kW solar array capacity (5.5kW × 2) and wide voltage range from 125–425VDC.
With support for lithium and lead-acid batteries, the SPI-UP series offers advanced BMS communication, a 200A PV charge current, and up to 120A grid or generator charge rate – making it ideal for battery-heavy systems.
Installers can scale the system to 6 units in parallel (max 60kW) for larger estates or commercial microgrids. Its industrial design and intuitive interface make setup and maintenance fast and user-friendly.
