Note 1: Some customers report Solar Grid Tie Inverter connecting solar panels, No light. This is because the customer has extended the solar panel connection cable. (Positive and negative poles are opposite)
Note 2: Some customers reported using the grid tie solar Inverter for less than 1 month, and the product showed a red light.stop working. This is because customers use solar panels of different specifications. For 600W, please use 2PCS solar panels with the same specifications. (Voltage, current, power, all need to be the same) Recommended solar panel: 2X300W Voc36-50V. Voc(of a solar panel) must be in the 36-50V range to ensure the good output efficiency Please do not install outdoors, avoid rain. You can install Solar Microinverters in a ventilated, dry, cool place.
Due to the special properties of solar panels, a wider range of voltage designs can achieve more energy. DC18-50V input, many customers will think that Solar micro-inverters can be used with DC18V/50V. This is a wrong understanding!
