3.7 Module (DC) Connection
WARNING: It's very important for system safety and efficient operation to use appropriate
cables for PV module connection
WARNING: Do NOT touch the connectors of the inverter when the photovoltaic modules are
exposed to sunlight. The PV modules can generate a DC voltage on the inverter terminals and
a risk of electric shock.
WARNING: Before connecting inverter to PV modules, install separately a DC circuit breaker
between inverter and PV modules. Install protection (circuit breakers, fuses and lightning
conductors) according to existing standards.
Before the photovoltaic system is connected, the solar array voltage must be verified to make
sure that it is correct.
Never move the inverter when the solar array is connected. I
f it‟s necessary, please disconnect the
solar array first (see general conditions).
Caution: Because this inverter is non-isolated, only two types of PV modules are acceptable: mono
crystalline and poly crystalline. To avoid any malfunction, do not connect any PV modules that may
introduce leakage current to the inverter. For example, non-grounded PV modules will cause leakage
current to the inverter. See manufacturer technical datasheet of the PV modules.
Step 1: Check the output voltage of PV modules string falls in the inverter range.
WARNING: Exceeding the maximum PV input voltage will damage the unit! Check the system
before wire connection.
Step 2: Check the polarity of the PV string and identify the positive input (+) and the negative input (-).
Step 3: Switch the DC breaker of the PV to OFF position.
Step 4: Wiring of the supplied connectors.
