INSTALLATION
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:
1. The unit x 1
2. User manual 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:
1. Do not mount the inverter on flammable construction
materials.
2. Mount on a solid surface
3. Install this inverter at eye level in order to allow the
LCD display to be read at all times.
4. The ambient temperature should be between 0°C and
55°C to ensure optimal operation.
5. The recommended installation position is to be
adhered to the wall vertically.
6. 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.

5
Install the unit by screwing three screws. It’s recommended to use M4 or M5 screws.
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.
Stripping Length:
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 、stripping length(L2) and tinning length(L1)
as below.

Please follow below steps to implement battery connection:
1. Remove insulation sleeve 18 mm for positive and negative cables based on recommended stripping length.
2. Connect all battery packs as units requires. It’s suggested to use recommended battery capacity.
3. Insert battery cable flatly into battery connector of inverter and make sure the bolts are tightened with torque
of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly connected and battery
cables are tightly screwed to the battery connector.

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 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. The recommended spec of AC breaker is50A.
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

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 six 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) N→Neutral (blue)
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)
L→LINE (brown or black)
N→Neutral (blue)
5. Make sure the wires are securely connected.
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.

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! It'’ 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
18N1H-A5E A 12 AWG 1.4~1.6 Nm
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.

PV Module Wire Connection:
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.
3. Make sure the wires are securely connected.
CT Connection:
Inverter will not only provide power to the backup load connected but also give power to the home load connected.
If PV power is insufficient, it will take grid energy as supplement. The inverter will not sell power to grid. In this
mode, a CT is needed. The installation method of the CT please refer to the chapter. The external CT will detect
power flowing back to the grid and will reduce the power of the inverter only to supply the local load, charge
battery and home load.
Note:
1. when the reading of the load power on the LCD is not correct, please reverse the CT arrow.
2. The external CT will become available after finishing setting program 12 of F0 group.

Setting F1 Programs:
Program Description Selectable option
Output source priority
SUB priority (default)
Solar->Utility->Battery
Solar energy is charged first and
then power to the loads.
If solar energy is not sufficient to
power all connected loads, Utility
energy will supply power to the
loads at the same time.
SBU priority
Solar-> Battery ->Utility
Solar energy provides power to the
loads as first priority.
If solar energy is not sufficient to
power all connected loads, battery
energy will supply power to the
loads at the same time.
Utility provides power to the loads
only when battery voltage drops to
either low-level warning voltage or
the setting point in program 05 of
F2 group.
SUF priority
Solar-> Utility->Battery
If solar energy is sufficient to
all connected loads and charge
battery, the solar energy could
feedback to the grid (sell power to
grid), but the feedback power must
be less than the setting point in
program 05 of F1 group.
If solar energy is not sufficient to
power all connected loads, Utility
energy will supply power to the
loads at the same time.

17
ZEC priority
(Zero Export To CT)
Solar->Battery- > Utility
Self-use mode
The units will not only provide power
to the connected load but also give
power to connected home load. If
PV power and battery power is
insufficient, it will take grid energy
as supplement. The units will not sell
power to grid. In this mode, a CT is
needed. The installation method of
the CT please refer to chapter about
CT connection. The external CT will
detect power flowing back to the
grid and will reduce the power of the
inverter only to supply the local load,
charge battery and home load.
