Description
KV500 Series Solar Pump Inverter | 220V Input 380V Output
Shenzhen KEVAN Drive Technology Co., Ltd. proudly presents the KV500 Series Solar Pump Inverter — a purpose-built solution for challenging environments like photovoltaic water pumping and off-grid industrial sites. Its standout capability lies in accepting single-phase 220V input and delivering three-phase 380V output, directly solving the long-standing challenge of operating three-phase equipment where only single-phase power is available.
With a flexible power range of 2.2kW to 18kW, the KV500 series combines solar-optimized MPPT algorithms, precision vector control, and multi-layer protection features into a compact, reliable package. Whether for agricultural irrigation, livestock watering, or small-scale industrial machinery, the KV500 delivers consistent performance, energy savings, and peace of mind in even the most remote locations.
Key Features
- Single-phase 220V Input / Three-phase 380V Output – Directly drives standard industrial three-phase motors without a step-up transformer
- Dual Power Supply Modes – Supports both AC grid input (single-phase) and DC photovoltaic input (PV+/PV-)
- Built-in MPPT Algorithm – Maximizes solar panel energy harvesting
- Motor Type Compatibility – Drives both asynchronous induction motors (IM) and permanent magnet synchronous motors (PMSM)
- IP20 Protection + Independent Air Duct – Enhanced heat dissipation and dust resistance
- Intelligent Protections – Dry-run protection, over-current protection, over-voltage suppression, low-frequency protection, and tank full detection
- Remote Monitoring Ready – RS485 communication supporting Modbus protocol
- Flexible Installation – Book-style narrow body design for easy cabinet mounting
