Introduction:
ESI-3KVA series inverter adopts digital intelligent control and complete high-frequency topology featuring stable performance and excellent resitance to jam. It’s output voltage is 110V/60HZ, 220V/50HZ and rated power is 3KVA. This product is widely used in these solar system for telecommunication, traffic, house, island, border defense, countryside, pastoral areas etc.
Performance:
1. Output pure sine wave , small waveform distortion rate.
2. Soft start function and high efficiency.
3. Strong load adaptability and stability.
4. Internal fuse against wrong connection for reliability and safety.
5. Protection against overcurrent and short-circuit, preventing product from burning.
6. Low voltage protection for battery input, preventing battery from over-discharging.
7. Input side DC and output side AC isolated against electric shock for more safety.
8. All-round protection and alarm function.
9. Complete high-frequency transform, small volume, light weight.
10. Main phase locked, bypass switch and on-grid are available (compatiable UPS function).
