2. INSTALLATION
2.1 Safety Clearance
The minimum clearance to the wall shall be larger than 30cm in order to
ensure proper ventilation.
In the event the ambient temperature is high, it’s recommended to increase
the distance of safety clearance to improve the heat dissipation.
2.2 Mounting Inverter on the Wall
The inverter is designed to either be placed on horizontal surface or be
mounted on the wall with various ways (as shown below). When mounting
the inverter on the wall,
1) The wall shall be solid and strong enough to carry the inverter;
2) The location of installation shall allow the user to read the LCD easily;
3) Two screws shall be firstly fixed on the wall (distance as shown below) so
that the inverter can be hung on the screws, recommended screw size is
M4*50~65mm.
4) After mounting the inverter, make sure it’s firmly mounted and won’t
easily fall off in the event of unexpected earthquake or vibration.

6
2.3 Batteries
Determine the size of battery
The inverter is designed with pre-set charging current and voltage. Given a
fixed charging current, under-sized batteries may shorten the battery life
while over-sized batteries may result in unreasonable recharging time.
It’s recommended the batteries capacity shall be no less than 100Ah.
Connect the battery cables
•The gauge of battery cables shall be no less than 6 AWG with 105˚C
rating.
•No matter how the batteries are connected (in series or in parallel),
make sure the cables’ terminal voltage is consistent with the inverter’s
specification (12V for 1000VA model and 24V for 2000VA model).
•It’s recommended to cover the battery terminals during the connection.
•Check the polarity of cables before connecting to the inverter.
•Connect the battery cables to the inverter’s battery terminals as
shown below.
Connect with single battery
Make sure the battery voltage meets the inverter’s specification (12V for
1000VA model and 24V for 2000VA model)

Connect with multiple batteries
While connecting multiple batteries, use the same brand/type
for all batteries. Do not mix the battery bank with different
brand/type of batteries.
The user may connect the batteries in series in order to double the voltage
connected to inverter. The diagram below illustrate how to connect two 12V
batteries in series to make up 24V (for 2000VA model)
The user may connect the batteries in parallel in order to increase the total
battery capacity without changing the battery voltage. The example below
shows parallel connection of multiple 12V batteries. While the total capacity
is times by the number of battery, the terminal voltage remains 12V.
Charging Current Setting Switch (available on 1000VA model only):
The user of 1000VA model may set the charging current of the charger
powered by AC input (not the solar battery charger) to either 15A or 20A,
depending on the capacity of batteries. The larger the battery size, the
larger charging current is needed in order to have reasonable recharging
time. However too large charging current could damage the batteries.
Please consult your battery supplier for suitable setting of charging current.
Recommendation:
When Battery capacity≤150AH, please select charger current as 15A
When battery capacity>150AH, please select charger current as 20A

2.4 PV (solar) string
Selection of PV panel
PV string is a connection of PV panels whose output voltage and current
vary under different illumination. And just like battery, the PV panel can be
connected in either series or parallel as per needed. Please consult the
supplier of PV panel so that the operational voltage and current fall within
the allowed range of the inverter as set out in the specification.
Please do not use PV panel which requires one terminal
connected to ground (e.g. thin-film panel).
Connect the PV strings
As the PV string generates power as long as illumination exists,
a circuit breaker shall be installed between the PV
string and
inverter so that the power from PV string can be switched off
when needed (e.g. regular maintenance).
To ensure better contact and reliability, ring terminal shall
be fit on the cables from PV string before connecting to
the inverter. The recommended size of ring terminal is

2.5 Connect AC Input Cables and Loads
Connect the AC input cables and loads to the receptacles as shown below.
2.6 AC Input Voltage Range Selector
A. “NARROW” setting:
Set the selector to “NARROW” when connected with loads which are more
sensitive on voltage range. With this setting, the inverter is more sensitive
to the voltage disturbance on the AC input and the input voltage range is set
at 170~280VAC while output voltage follows input voltage.
B. “WIDE” setting:
Set the selector to “WIDE” when connected with loads which are less
sensitive on voltage range (e.g. light bulb, fan, fluorescent tube, or TV). With
this setting, the inverter’s input voltage range is extended to 90~280VAC
while output voltage follows input voltage.
Please note that the inverter’s transfer time switching from
Line Mode to Backup Mode gets longer as the input voltage
gets low. Under the circumstance, connecting the inverter with
loads which are sensitive to transfer time (e.g. computer) might
result in power interruption.

3. OPERATION
After connecting batteries, AC input cables, and loads, the inverter is now
ready to work.
3.1 Standby Charging Mode
The battery can be charged without switching on the inverter, and such
operation is called Standby Charging Mode. When AC input cable and
battery is connected, the inverter will enter into Standby Charging Mode
and LCD will be turned on with the following display.
If PV string is also connected with enough voltage, the display will be as
shown below to indicate the power flow from PV string.
Even if AC input is absent, PV power can still charge the battery and the
display will be as shown below.

11
3.2 Operation Modes (after powered on)
Press the Power ON/OFF button to power on the inverter and the inverter
will automatically enter into either of the operation mode according to the
condition of AC input and PV input as shown in the table below,
LINE MODE 1
AC input power is present but there is no PV power (e.g. night time). Load is
supplied by AC input power directly.
LINE MODE 2
Both AC input and PV input are present. Load is supplied by either AC input
or PV input depending on the priority switch’s setting.

12
Priority Setting Switch
In LINE MODE 2, if priority setting switch is set to give PV priority and PV
power is also strong enough to support load, the AC input will not
be consumed even though it is present. This is deemed an energy-saving
operation.
BACKUP MODE 1
Both AC input and PV input are absent. The backup power to load comes
only from battery. T
he backup time is determined by the capacity of
battery.
BACKUP MODE 2
AC input is absent and PV power is not enough to support loads completely.
The insufficient power is covered by battery.
The larger the PV power, the less consumption from battery and therefore
the longer backup time.

13
BACKUP MODE 3
AC input is absent and PV power is strong enough to not only support the
load but also charge the battery.
As long as the PV power persists, the load can be powered continuously
without consuming power from battery.
3.3 Fault Mode
Inverter enters into Fault Mode when there is a fault event. The fault icon
will be shown with a fault code. Please refer to fault code table in “Trouble
shooting” section.
