Sp-Series-1kw-3kw-Grid-Tied-Inverter

Short Description:

✔️ ruggid casting aluminum alloy case
✔️ leading edge capacitor control technology
✔️ dymanic MPPT efficiency>99.9%; european efficiency >97.2%
✔️ big LCD dislay
✔️ IP65,waterproof
✔️ WiFi or GPRS monitoring

Using Digital Technology

Knox PV on grid inverter using America’s TI’s digtal control chip,the same chip as the 2nd generation of world well-known brand SMA, so in face of external disturbance and abnormal changes in the grid,the system can automatically identify and ajudst to maximize the grid compatibility and to maintain the stability of the pv system
