To reduce risk of damage and injury, please use batteries with good quality.
In the event flooded batteries are used, regular maintenance on the battery shall be performed.
The product is design for indoor installation. Please do not expose the product to direct sunlight, rainfall, or snow.
Before performing any maintenance on the product, please disconnect all power sources (AC mains, batteries, solar panel) to
avoid the risk of electrical shock.
Do not attempt to disassemble or repair the product. Only authorized personal are allowed to perform repair.
While performing maintenance or cleaning (especially on the batteries where hazardous liquid might be touched), it’s
recommended to wear necessary personal protections (e.g. gloves and goggle).

PRODUCT OVERVIEW
This is a DC-to-AC inverter, which can be used as a long run-time UPS (Uninterruptible Power Supply), an energy-saving solution or
an automotive inverter (hereinafter referred to as “inverter”).
The inverter accepts input power source from AC mains (utility), battery and PV (solar) string and switches between various
operation modes automatically depending on the operational conditions.
When used as an UPS, battery or PV (solar) string acts as back-up power source to supply loads during the outage of AC mains.
When used as an energy-saving device, the PV (solar) string can be set as priority to supply the loads without consuming the power
from AC mains, as long as sufficient sunlight is present.
The battery can be charged by both AC mains and PV (solar) string with intelligent charging control.
Key features:
 Automatic line-to battery switchover
 Built-in enhanced AC charger
 Built-in solar charger controller up to 60A
 Selectable input voltage ranges/charging priority setting/AC or solar power priority setting.
 High efficiency DC-to-AC conversion with minimized energy loss
 Rack design & wall-mounted design for flexible installation
 Intelligent 3-stage charger control for efficient charging and preventing overcharge
 Auto restart upon AC recovery
 User-friendly LCD and LED indications with setting function
 With the environmental temperature control charge management
 Multiple protections: low battery alarm, low battery shutdown, over charger protection, overload protection, over temperature
protection, short circuit protection

INSTALLATION
Unpacking and Inspection
This product package include following items. Please call your supplier or dealer if any items are missing.
 1 X Inverter
 1 X User’s manual
 2 X Setting screws
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.
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,
The wall shall be solid and strong enough to carry the inverter;
The location of installation shall allow the user to read the LCD easily;
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.
After mounting the inverter, make sure it’s firmly mounted and won’t easily fall off in the event of unexpected earthquake or vibration.
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 200AH.
Connect the battery cables
The gauge of battery cables shall be no less than 6 AWG with 105℃ 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 (24V for 3000VA model and 48V for 5000VA model).
It’s recommended to cover the battery terminals during the connection.
Check the polarity the cables before connecting to the inverter.
Connect the Inverter DC cables with battery terminals as shown below

8 6
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 3000VA model) and four 12V batteries in series to make up 48V (for 5000VA model)
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 or 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)

8 7
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)
Connect the cables from PV string to PV input terminals as shown below. Please check the polarity before connection.
Connect to Utility and charge Connect AC input Cables and loads
Connect the AC input cables and loads to the receptacles as shown below.
Plug in the AC input power cord to the wall outlet. The unit will automatically charge the connected external battery even though the unit is off.
AC input voltage range selector
“NARROW “setting:
Configure LCD 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 input voltage range is set at 170~280VAC while output voltage follows input voltage.
“WIDE “setting:
Configure LCD 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 input voltage range is set at 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.

8 8
OPERATION
After connecting batteries, AC input cables, and loads, the inverter is now ready to work.
Power on/off
Once the inverter has been properly installed, press the power switch to turn on the unit. The unit will work automatically in line mode or inverter
mode according to input utility power’s status. When press the power switch again, the unit will be turned off.
LED Indicators
The operation mode of the inverter can be easily understood by LED indicators. Please see the table below for details.
