Polaris 5.5K-48V Off Grid Energy Storage Inverter

The Polaris 5.5K-48V Off Grid Energy Storage Inverter is a pure sine wave 5.5kVA/5.5kW solar inverter designed for reliable off-grid and hybrid applications, delivering stable 230VAC output with power factor 1 for residential and small commercial loads. Featuring a high PV input voltage range of 120–450VDC (up to 500VDC open-circuit) and maximum PV array power of 5500–6000W with a built-in 100A MPPT solar charger, it optimizes solar energy harvest and supports flexible panel configurations. This advanced 48V inverter enables battery-independent operation, battery equalization for extended lifecycle, and parallel scalability up to 9 units for single-phase output to 49.5kW or three-phase systems. With an integrated anti-dust kit for harsh environments, fast 10–20ms transfer time, peak efficiency up to 93.5%, and compact wall-mounted design (100 × 300 × 440 mm, 10 kg), it ensures efficient, durable performance across -10°C to 50°C operating conditions. It carries a 15-year warranty for materials and processing and a 25-year warranty for extra linear power output
