INTRODUCTION
This hybrid PV inverter can provide power to connected loads by utilizing PV power, utility power and battery
power.
Battery
Figure 1 Basic hybrid PV System Overview
Depending on different power situations, this hybrid inverter is designed to generate continuous power from PV
solar modules (solar panels), battery, and the utility. When MPP input voltage of PV modules is within
acceptable range (see specification for the details), this inverter is able to generate power to feed the grid
(utility) and charge battery. Never connect the positive and negative terminals of the solar panel to
the ground. See Figure 1 for a simple diagram of a typical solar system with this hybrid inverter.

Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should
have received the following items inside of package:
Inverter unit Software CD Manual RS-232 cable Parallel communication cable
Current sharing cable Fixing screws Mounting plate
Preparation
Before connecting all wirings, please take off bottom cover by removing four screws as shown below.
Installing the Unit
Preparation
This hybrid inverter is designed for indoor or outdoor use (IP65), please make sure the installation site meets
below conditions:
Not in direct sunlight
Not in areas where highly flammable materials are stored.
Not in potential explosive areas.
Not in the cool air directly.
Not near the television Antenna or antenna cable.
Not higher than altitude of about 2000 meters above sea level.
Not in environment of precipitation or humidity (>95%).
Please AVOID direct sunlight, rain exposure, snow laying up during installation and operation.
Select the Mounting Place
Please select a vertical wall with load-bearing capacity for installation, appropriate for installation on
concrete or other non-flammable surfaces.
The ambient temperature should be between -25~60℃to ensure optimal operation.

5
Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation
and have enough space for removing wires.
For proper air ventilation to dissipate heat, allow a clearance of approx. 50cm to the side and approx.
50cm above and below the unit. And 100cm toward the fro
Mounting the Unit
WARNING!! Remember that this inverter is heavy! Please be careful when lifting out from the package.
Installation to the wall should be implemented with the proper screws. After that, the device should be bolted
on securely.
The inverter only can be used in a CLOSED ELECTRICAL OPERATING AREA. Only serviceperson can enter this
area.
1.
Put the mounting plate against the wall. Fix the
mounting plate with the supplied four scr
ews as
shown in the chart. The reference tightening torque is
35 N.m.
2. Raise the inverter and place it over the mounting
plate.
3. Fix the inverter in position by screwing the supplied
four screws (M5*4) located on the two sides of the
inverter.
4. Check if the inverter is firmly secured.
WARNING!! FIRE HAZARD.
SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY.

6
Battery Connection
CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current
protector or disconnect device between battery and inverter. It may not be requested to have a disconnect
device in some applications, however, it’s still requested to have over-current protection installed. Please refer
to typical amperage in below table as required fuse or breaker size.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury, please use the
proper recommended cable and terminal size as below.
Recommended battery cable and terminal size:
Model Typical
Amperage
Battery
Capacity Wire Size Torque Value
ELEGO-6KW-IP65 104/125A 200AH 1*2AWG 2~3 Nm
Please follow the below steps to implement battery connection:
1. Remove insulation sleeve 7mm for two conductors.
2. Insert battery wires according to polarities indicated on the terminal block and tighten the terminal screws.
Make sure polarity at both the battery and the inverter/charge is correctly connected.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected
tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) must be connected to positive (+) and negative (-) must be connected to negative (-).

7
AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between
inverter and AC input power source. This will ensure the inverter can be securely disconnected during
maintenance and fully protected from over current of AC input.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input
and output connectors.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use
appropriate cable for AC input connection. To reduce risk of injury, please use the
proper recommended cable size as below.
Suggested cable requirement for AC wires
Model Gauge Torque Value
ELEGO-6KW-IP65 10 AWG 1.2~ 1.6 Nm
Please follow below steps to implement AC input/output connection:
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 7mm for six conductors.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be
sure to connect PE protective conductor ( ) first.
→Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)
WARNING:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.

4. This inverter is equipped with dual-output. There are two outputs: AC output 1 and AC output 2. It’s set up
through LCD program or monitoring software to turn on and off the second output. Refer to “LCD setting”
section for the details.
Insert AC output wires according to polarities indicated on terminal block and tighten terminal screws. Be
sure to connect PE protective conductor ( ) first.
→Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)
AC Output 1 AC Output 2
5. Make sure the wires are securely connected.
CAUTION:Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required
to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a
short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check
manufacturer of air conditioner if it’s equipped with time-delay function before installation. Otherwise, this
inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes
internal damage to the air conditioner.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause
utility short-circuited when these inverters are worked in parallel operation.

PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
WARNING! All wiring must be performed by a qualified personnel.
WARNING: Please switch off the inverter before you connect PV modules. Otherwise, it will damage the
inverter.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for PV
module connection. To reduce risk of injury, please use the proper recommended cable size as below.
