Description Datasheet

Solis > 11.4kW 220/240 VAC Single Phase Residential Hybrid Storage Inverter

The Solis 1P5K-4G-US-APST single phase string inverter is extremely efficient, increasing the amount of electricity generated and recover investment returns more quickly. The 1P5K-4G-US-APST is suitable for the installation of single-phase input PV system of different types; residential, commercial and industrial and adopt ultra-high switching frequency, ultra-thin single four-layer board design can greatly reduce the risk caused by the connector. The EPM can be equipped with built-in counter-current controller, which supports multiple communication modes such as RS485, WIFI, GPRS, Ethernet and so on. Real-time monitoring and information control can be utilized.
