inverter is zero when the switch is working)
6. At over 1,000 meters altitude, the inverter's heat dissipation function worsened due to the thin air, it is necessary to use
less.
7. The inverter output voltage is pulse wave type. If using digital multi-meter measurement, deviation of the reading will be
great. And the deviation is different by using different type of digital multi-meter. Under normal circumstances, while RMS
380V, digital multi-meter reading is around 450V.
8. Solar panel can be connected in the series or parallel. For rated voltage 380V controller, we suggest working voltage
between 480V and 560V while MPPT. What means the solar panel open circuit voltage should be between 600V and
700V.

1.5 Cautions in Disposal
When you dispose frequency inverter, please pay attention to:
1. Electrolytic capacitor: the electrolytic capacitor of main circuit or the printing plate may explode when they are burned.
2. Plastic: plastic incineration may generate toxic gases.
3. Dispose method: please dispose as industrial waste.
