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 plug connected well, whether there is loose connected;
(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 end point V1 (as shown in figure) at the system full load output (Max. output);
5 Please measure AC voltage of the grid-connecting point V2 (as shown in figure) at the system full load output (Max. output);
6 The voltage difference between V1 and V2 must 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 the this range: 190V~252V;
8 Micro Inverter of 120V version: please ensure that the grid-connecting point voltage V2 is in the this range: 90V~152V;
9 Strictly unplug the inverter connector with electricity, power grid MUST be cut off while unplug!;
