7-1 Measuring method
● Do not measure PV arrays with open-circuit voltage of 1000 V or more.
● Test and verify the insulation of P terminal prior to measuring insulation
resistance between N and earth terminals of PV array. If the measured
resistance value is low, do not perform further measurement so as not to
damage solar cells and modules.
(1) Press the PV button to select insulation resistance function for PV system.
The LCD shows "SOLA" about one second and the PV LED lights up.
(2) Connect the test leads as Fig. 7-1 shows.
