Please use PV cable to connect modules to inverter. From junction box(Must have fuse
spec.:1000V, 25A fast action) to inverter, voltage drop is about 1-2%. So we suggest
the inverter install near PV module, in order to save cable and reduce DC loss.
Note
!
Please don’t connect the PV panel positive or negative to ground.
And do not apply for thin film panel.
Figure 9 Use multimeter to measure module array voltage and detect the polarity
Note :
Check the PV+ and PV- from the PV string combiner box correctly, Make sure the PV+
and PV- are connected correctly.
Warning
!
PV module voltage is very high which belongs to dangerous voltage
range, please comply with electric safety rules when connecting.
Warning
!
When there is something wrong with module arrays, modules can be
connected with PV grid-tied inverter only after eliminating these problems.
