PV module voltage is very high which belongs to dangerous voltage
range, please comply with electric safety rules when connecting.
WARNING!
When the photovoltaic array is exposed to light, it supplies a D.C
voltage to the PCE.
WARNING!
When there is something wrong with the modules arrays. Modules
can be connected with inverter only after eliminating these problems.
WARNING!
Ÿ PV string connection
The following requirements of PV modules need to be applied for
each input area;
• Same type • Same quantity • Identical alignment • Identical tilt
NOTE!
6.6 Connections of The X-hybrid System
6.6.1 The Main Steps to Connect The X-Hybrid System
-PV string connection
-AC output connection
-Battery connection (for SK-SU series)
Battery power connection
Battery communication connection
Battery thermal sensor connection
-Current sensor connection
-EPS connection (for E version)
-Earth connection
-Wifi connection
X-hybrid series inverters can be connected in series into 2-strings PV modules
for 3.7KW and 5KW, and 1-string PV module for 3KW.
Please select PV modules with excellent function and reliable quality.
Open-circuit voltage of module arrays connected in series should be <Max. DC
input voltage; Operating voltage should be conformed to MPPT voltage range.
