The PV500 is FRECON's three-phase 380 V solar pump inverter for larger installations: 4 to 160 kW in the current catalog, with the user manual extending the range to 630 kW. PV input spans 230–800 VDC (900 VDC available as a custom option) with recommended array open-circuit voltage of 600–750 V, and MPPT efficiency reaches 99%. Hybrid supply blends solar DC with grid AC through automatic DC/AC switching — no battery required.

It drives asynchronous, permanent-magnet synchronous and BLDC pump motors, sleeps automatically in weak light and wakes when the sun returns. Protection covers over-current, over-voltage, phase loss, short circuit, over-temperature, dry-run and tank water-level control, and the drive records generated energy, water flow and operating hours. An optional 4G/Wi-Fi module adds real-time remote monitoring and operation from app and web.
