6.7.1 PV string connection
WARNING!

PV module voltage is very high which belongs to dangerous voltage
range, please comply with electric safety rules when connecting.

When the photovoltaic array is exposed to light, it supplies a D.C voltage
to the PCE.

When there is something wrong with the modules arrays. Modules can be
connected with inverter only after eliminating these problems.
ESC-hybrid series inverters can be connected in series into 2-strings PV modules, 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.
Please use PV cable to connect modules to inverter. From junction box 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. (No longer than 30m)

NOTE!

The following requirements of PV modules need to be applied for each
input area;
• Same type • Same quantity • Identical alignment • Identical tilt

Please do not make PV positive or negative ground!
