Solis mini-2500-S6 Single Phase Grid-Tied Inverter 2.5 kW

The Solis mini-2500-S6 is a compact, lightweight single-phase grid-tied inverter rated at 2.5 kW AC output, ideal for smaller residential photovoltaic installations. It features high-frequency switching technology, a wide DC voltage range (80–500 V MPPT), and a low start-up voltage of 90 V for optimal energy harvesting.

Key specifications include one MPPT tracker with one DC input string, a maximum input current of 14 A, and a maximum AC output current of 13.3 A. The inverter achieves 97.1% maximum efficiency and includes integrated arc-fault circuit interrupter (AFCI) protection, multi-peak scanning, and an Export Power Manager (EPM) for grid management. Communications are via RS485, with optional Wi-Fi, LAN, or GPRS connectivity via a data logging stick.

Housed in a transformerless topology with natural cooling, it operates in an ambient temperature range of −25 to +60°C, offers IP66 ingress protection, and weighs 7.7 kg. The unit complies with major grid connection standards including EN 50549-1, VDE-AR-N 4105, and IEC 62116, and carries a 10-year warranty in Europe.
