Brand: Prostar
Commodity name: On/Off Grid Solar Inverter 4.2kW-6.2kW

Prostar PHS PRO Series enables adaptive multi-mode operation (Grid-tie/Off-grid/Grid-tie with Backup), dynamically balancing energy self-consumption, grid export, and backup readiness. With wide PV input (60-500VDC/27A), scalable phase configurations, and parallel expansion (12 units), it supports LiFePO4 integration via RS485 BMS, PV/utility battery recovery, and customizable charging. Built-in WiFi/OTA and pure sine wave output (220-240VAC) ensure intelligent, resilient power management for residential/commercial applications.
