300W TUYA WIFI model IP66 waterproof solar micro inverter

Micro inverter-300W

• The inverter ONLY works when it is connected to the grid. If the unit is unplugged, there is no feed-in.There is no voltage at the output and the indicator lights up red.
• The maximum voltage and wattage of all connected PV panels must NOT exceed the max voltage and wattage of the inverter, otherwise the unit will be damaged. Please refer to the technical data.
• Before maintenance work, the PV panels and all connections must be disconnected from unit.
• The unit may only be opened by qualified personnel.
• The current generated by the PV modules cannot be switched off. To do this, disconnect the panels from the inverter. Otherwise there is a danger of electric shock.
• Do NOT remove the lid. Servicing must be performed by qualified service personnel.
• Protect the inverter from direct sunlight and rain, e.g. by mounting it behind a PV panel.
• Do NOT cover the unit as it may overheat.

• NOTE: Unused connections must always be closed, otherwise water may enter and a short circuit may occur.
