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.

User manual x 1
Communication cable x 2
Software CD x 1
Preparation
Before connecting all wirings, please take off bottom cover by removing two screws as shown below.
Mounting the Unit
Consider the following points before selecting where to install:
Do not mount the inverter on flammable construction materials.
Mount on a solid surface
Install this inverter at eye level in order to allow the LCD display to be
read at all times.
The ambient temperature should be between 0°C and 55°C to ensure
optimal operation.
The recommended installation position is to be adhered to the wall
vertically.
Be sure to keep other objects and surfaces as shown in the right
diagram to guarantee sufficient heat dissipation and to have enough
space for removing wires.
SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY.

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.

Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the nuts are
tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and ring terminals are tightly screwed to the battery terminals.
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 (-).

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
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 10mm for eight conductors. And shorten phase L and neutral conductor N 3 mm.
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)

WARNING:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
4. Then, 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)

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.
Model Typical Amperage Cable Size Torque
27A 10AWG 2.0~2.4Nm
PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.
Solar Charging Mode
INVERTER MODEL
Max. PV Array Open Circuit Voltage 500 Vdc
PV Array MPPT Voltage Range 120~430Vdc
MPP Number 1
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Check correct polarity of connection cable from PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable to positive
pole (+) of PV input connector. Connect negative pole (-) of connection
cable to negative pole (-) of PV input connector.
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.
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.
