Installation

1. Installation Instructions

Unpacking Inspection: Open the package, check accessories, and inspect for damage during transportation. Inform the carrier and distributor of any damage or missing parts.
Note: Keep the packing box and materials for future transportation. The products are heavy; handle with care.

2. Installation Precautions

Ensure the inverter area is well-ventilated, away from flammable gas and corrosive agents.
Keep the side panel fan air inlet, air outlet, and box air inlet unobstructed.
Maintain ambient temperature between 0℃-40℃.
If the machine is disassembled and used at low temperatures, condensation may occur. Ensure the inside and outside are completely dry before installation and use to avoid electric shock.
Install the inverter near a mains input socket or switch for easy emergency power cutoff.
Do not connect the inverter output directly to the mains.
Note:
- When connecting the load, turn off the load before wiring, then turn the load on one by one.
- Connect the inverter to a special socket with overcurrent protection.
- The power socket used should be connected to the protective earth terminal.
- The inverter output may be charged regardless of whether the input power cord is plugged in. To ensure no output, turn off all switches and then cut the mains power.
- For inductive loads (motors, monitors, laser printers), consider the starting power. Calculate inverter capacity based on starting power.

LCD Panel Description

The LCD panel displays system information and allows for various settings.

System Setting Interface: Long press the [setting key] for 3 seconds to enter. Pressing the [setting key] confirms selections. The backlight turns off automatically after 5 seconds of inactivity (energy saving). Press the [setting key] again to turn on the backlight.
Energy Saving (Sleep) Function: When the inverter operates in battery mode with no load, it enters a sleep state (off output) after 20 seconds to save energy. It automatically resumes when a load is applied.

Working Mode Setting

Set AC Charging Current: In the system setting interface, use the [up/down keys] to select "Set AC charging current", press [confirm key]. Select the desired charging current and press [confirm key]. Different inverter specifications have different charging current values.
Set Priority AC/Battery: In the system setting interface, use the [up/down keys] to select the priority status (AC or Battery), and press [confirm key]. The system interface will display the current work priority after 5 seconds.
AC Priority: The mains power supply has priority. The battery power supply starts instantly during mains failure (milliseconds switching, no impact on appliances) and functions as a UPS. When mains power is restored, it automatically switches back to mains and charges the battery.
Battery Priority: The battery power supply has priority. When battery power is low, it switches to mains power supply, and the battery charges automatically. Battery power supply restores automatically 30 minutes after the battery voltage reaches a set value. The protection board can be disconnected for charging without turning on the inverter, allowing intelligent battery repair and extended service life.
Tip: Switching between AC and Battery mode requires a 30-minute interval.
Energy-saving Output (SAVER): In the system setting interface, use the [up/down keys] to select "SAVER", press [confirm key]. Select "off" or "on" for saving output and press [confirm key]. The system interface displays the SAVER setting after 5 seconds.
SAVER On: The inverter enters sleep state (turns off output) after 20 seconds when in battery mode with no load (low power consumption below 3W). It starts automatically after loading.
SAVER Off: The inverter remains active and does not enter sleep state.
Backlight Setting (Normal/On): In the system setting interface, use the [up/down keys] to select "Backlight", press [confirm key]. Select "On" (backlight stays on) or "Normal" (backlight turns off after 1 minute of inactivity) and press [confirm key]. The system interface displays the backlight setting after 5 seconds.
Battery Setting: In the system setting interface, use the [up/down keys] to select "Set" and press [confirm key]. In the battery setting interface, use the [up/down keys] to select the battery parameter to adjust. Press [increase key] to increase voltage, press [decrease key] to decrease voltage. Voltage changes take effect after 5 seconds. The interface returns to the inverter information screen after 30 seconds of inactivity.
CC-V: Constant voltage charging.
FLA-V: Float charging.
DC-REC: In battery priority mode, mains power supply restores battery power supply automatically 30 minutes after the battery voltage reaches the set value.
B-LVD: Low voltage protection (shutdown).
LB-Aal: Low voltage alarm (beeping).
AC-REC: In battery priority mode, automatically switches to mains priority when the battery voltage drops to this value.

Charging Current Comparison

Users can select charging gear based on power demand. Daily charging is recommended at low or medium gear.

Input & Output Connection

Connection Diagram

12V battery Connection diagram: Connect the battery positive and negative terminals to the corresponding inverter terminals. Ensure the remote control interface is connected.

24V battery Connection diagram: Connect two 12V batteries in series to achieve 24V. Connect the battery positive and negative terminals to the corresponding inverter terminals. Ensure the remote control interface is connected.

48V battery Connection diagram: Connect four 12V batteries in series to achieve 48V. Connect the battery positive and negative terminals to the corresponding inverter terminals. Ensure the remote control interface is connected.

AC Input & Output Connection

AC Output: For appliances up to 1200W.
AC Input: Connect L to live wire, N to neutral wire.
Earth Wire: Connect to the earth terminal.
Plug the mains to charge the battery (mains power is not necessary for operation).
Plug high-power appliances into the AC output.

Generator Connection

If connecting to a generator:

Start the generator and wait for stable operation. Connect the generator's output power to the inverter's input (ensure the inverter is no-load). Start the inverter according to the startup procedure. After the inverter starts, connect the load one by one.
It is recommended to choose a generator with a capacity two to three times the inverter's capacity.

Maintain & Maintenance

This series of inverters requires minimal maintenance. The standard model uses valve-regulated, low-maintenance batteries that need frequent charging for optimal life.
If the inverter is not used for a long time, charge it every two to three months.
Battery service life is typically three years. Replace batteries in poor condition early, preferably by a professional.
Do not replace batteries individually. Follow the battery supplier's instructions when replacing the entire battery. Normally, charge and discharge the battery every two to three months. Charging after shutdown should not be less than 12 hours.
In high-temperature areas, charge and discharge batteries every two months. The standard machine charging must not be less than 12 hours each time.

Maintenance Notes:

Turn off and disconnect the inverter from the mains before replacing the battery.
Remove metal objects like rings and watches.
Use insulated tools and do not place tools or metal objects on the battery.
Small sparks at the connector when connecting the battery cable are normal and do not pose a safety risk.
Never short-circuit or reverse the battery's positive and negative poles.

Simple Maintenance and Repair Methods

Malfunction	Reason	Solution
The fan not works	The temperature inside the inverter does not over 45°C	It is normal, the fan is temperature control
The terminal is hot	Poor contact or loose	Re-tighten
Shutdown with load	Battery does not have enough power or over load	Charge your battery or reduce load
Can't turn on the inverter	The battery cable is not connected properly	Check if the battery cable is connected and reconnect it
Power-on alarm	Battery do not have enough power or over load	Charge your battery or reduce load
