Xinpuguang 600 Watt On-grid Micro Inverter System Kits Connect Solar Panel

1. After the solar power generation system is installed correctly, do the following test preparation work before the AC power-up:

(1）Please check whether all the plugs connected well, whether there is a loose connection;
(2) Measure all L-N, L-G, N-G of each branch, in order to no short circuit, if there is a short circuit, please correct;
(3) Complete the above preparation work and prepare the test run;

2. The time point of test run, please select noon and the sunshine is the most strong time of the local time;

3. To connect AC power to see if each inverter is on the green light or fast flashing;

4. Please measure each branch's AC voltage of the AC endpoint V1 (as shown in the figure) at the system full load output (Max. output);

5. Please measure AC voltage of the grid-connecting point V2 (as shown in the figure) at the system full load output (Max. output);

6. The voltage difference between V1 and V2 must be less than 5V, if more than 5V then the load capacity of the main/branch cable is not enough;

7. Micro Inverter of 230V version: please ensure that the grid-connecting point voltage V2 is in this range: 190V~252V;

8. Micro Inverter of 120V version: please ensure that the grid-connecting point voltage V2 is in this range: 90V~152V;

9. Strictly unplug the inverter connector with electricity, power grid MUST be cut off while unplugging!
