Introduction
Thank you for purchasing EnerSolis Grid-Tied PV Inverter.
We are a specialized manufacturer of power equipment, with
years of experience in development and production. We hope that
this equipment will facilitate smooth and error-free operation of
your solar system for years to come. However, a power system
with PV inverter is a complicated system and failures may occur. If
you encounter any errors or malfunctions in the PV inverter or
system, please call us or the local distributor. We will provide
prompt assistance to solve your problems.
Please read this user manual carefully to ensure quick and
correct installation of the equipment.

Safety Instructions
 Please read all the installation instructions in
this EnerSolis user manual before installing or
maintaining your system.
 The PV inverter should be opened by qualified electrical
technicians only.
 When the photovoltaic array is exposed to light, it
supplies a d.c. voltage to the PV Inverter.
CAUTION:
Maintenance of EnerSolis should be performed by
qualified electrical technicians, and only after all AC and
DC power are completely disconnected from EnerSolis.
 EnerSolis must be disconnected from the utility and
make sure that there is no accidental connection with the
utility. The PV array must also be disconnected
with EnerSolis.
CAUTION:
As EnerSolis has a built-in high voltage capacitor, fatal
high voltage remains in the inverter for some time after
it is shut down.

4
 After the inverter is shut down and the utility and the PV
array are disconnected from EnerSolis, please wait for
the internal capacitor to discharge before opening the
unit for maintenance.
 Warnings

 Repair and Maintenance
PV inverter should be repaired by trained electrical
technicians only.
 PV Array
When installing and configuring the PV array, make sure
that the PV array's rated voltage parameters which provided by
the manufacturer could meet the applicable specifications.
Make sure the open-circuit voltage of the PV array under
intensive sun, with ambient temperature of -13°F (-25°C), does
not exceed maximum withstanding voltage of EnerSolis
(500Vdc). Voltage exceeding 500Vdc will cause permanent
damage to PV inverter.
 Grid connection
Only the distributor whom has a licensed electrical
engineer can install the PV inverter. To install and operate to
the grid require the permission from the local power company.
Please contact your local distributor for installation details.

2.4 Electrical Installation
CAUTION:
Maintenance of EnerSolis should be performed by
qualified electrical technicians, and only after all AC and
DC power are completely disconnected from EnerSolis.
 Make sure the AC circuit breaker has been installed
between the PV inverter and the utility.
Note: The Ue: 240Vac / Ie: 30A circuit breaker is
recommended.
 Make sure the DC circuit breaker has been installed
between the PV inverter and the PV array.
Note: The Ue:600Vdc / Ie: 20A circuit breaker is
recommended.
 The AC and DC circuit breaker must be disconnected
during installation process.
 During installation, make sure that both the AC and DC
circuit breakers are turned off.

2.5 Connecting to the Grid (AC utility)
CAUTION:
An AC circuit breaker should be installed between the
PV inverter and the utility before wiring the unit to the
utility.
Step 1: Make sure that the utility voltage and utility frequency
meet the specifications of the PV inverter.
Step 2: Make sure the circuit breaker which connected to the
utility is opened before installed the PV inverter’s AC
output. The AC circuit breaker should be closed only
after completed the electrical installation of the PV
inverter.
Step3: As shown in Figure 2, remove the cover of AC
output. Follow the steps in Figure 3 to set the AC
output wiring by using the recommended wire
diameter. You can follow the instructions in Figure 4 to
adopt different wiring methods for the desired output
voltage.

2.6 PV Array Input Wiring
The PV inverter is equipped with specific quick installation
terminals for PV array, as shown in Figure 6.
Figure 6
2.6.1 Precautions of PV Array Configuration
The number and connection of the PV modules have to
meet the PV inverter specifications and the following three
requirements:
1 To prevent damage to the PV inverter, make sure that the
maximum open-circuit voltage (Voc) less than500Vdc in
each PV array. Voltage exceeding 500Vdc will cause
permanent damage to the PV inverter.
2 Maximum short circuit current (Isc) for each PV array
should less than the maximum input current which
specified on PV inverter.
3 The maximum power voltage for the PV array should
remain within the maximum power tracking range under
any kind conditions.
21
2.6.2 Installation steps for PV array input
CAUTION:
An independent DC circuit breaker shall be installed
between the inverter and the PV array before the PV
inverter is connected to the PV array.
 Follow the steps below for connecting of the PV array to
the PV inverter:
Step 1: Ensure the correct polarity of the PV array, and
the voltage less than the PV inverter's maximum
input voltage (500Vdc).
Step 2: Connect the PV array's positive polarity to the PV
inverter's positive terminal.
Step 3: Connect the PV array's negative polarity to the PV
inverter's negative terminal.
Step 4: For a multi-string PV array, repeat Steps 1 to
Steps 3.
Step 5: Cover up other unused terminals on the PV
inverter with the protective lids to avoid potential
electric shock.
