3.3 Wiring Diagrams
Proper wiring is crucial for the safe and correct operation of the inverter. Refer to the diagrams below for battery and AC input/output connections.
Connection Notes for Output Load:
The connection between the load of 110VAC and 220VAC must follow the connection as below:
- The load of 110VAC shall be firstly connected to N-HOT1 terminals. The load power shall be half of the rated power of the inverter with load detection function and loads powered percentage display.
- While N-HOT2 terminal is connected to the load of 110VAC, its power shall not exceed half of the rated power of the inverter. The output terminal has no load detection function and load percentage display.
- The load of 220VAC is connected to the HOT1-HOT2 terminal. The load power is the rated power of the inverter with load detection function and load percentage display.
If necessary, it is recommended that the N-HOT2 terminals should not be connected to the load of 110VAC. If the load needs to be connected, it should strictly control the load power and not exceed half of the rated power. At this point, the HOT1-HOT2 terminal cannot connect to the load of 220VAC.
Direction for using of wire diameter:
Direction for using of battery, AC input/output wire diameter: (Compute depends on 1mm² copper core with 4-5A current)
Battery wire diameter = Rated power(W) / (Rated battery(V) x 5A/mm²)
AC wire diameter = Rated power(W) / (Rated AC voltage(V) x 5A/mm²)
For example: Wire diameter of 5000W/48Vdc/220Vac as below:
Battery wire diameter = 5000W / (48V x 5A/mm²) ≈ 20(mm²)
AC wire diameter = 5000W / (220V x 5A/mm²) ≈ 6(mm²)
3.4 Electric Generator Connection Announcements
If connecting an electric generator, it needs to operate as below:
- Start up the electric generator and after it runs stably, connect the electric generator output power supply to the equipment input terminal. Ensure the equipment output is no-load, then start up the equipment.
- After the equipment starts, connect loads one by one.
- It is suggested that the electric generator capacity should be 2-3 times that of this equipment.
4. Operating Instructions
4.1 Panel LCD Display Graphical Representation Instruction
The LCD display and function keys interface allows you to monitor and control the equipment's working status, including input/output voltage, frequency, grid mode, inverter mode, battery capacity, load capacity, and alarm warnings.
| Function Key | Instruction |
|---|---|
| Mute/function key | Sound attenuation with short press; enter into equipment working mode with long press (5s). |
| Function key/multiply key | Enter into charge current setting with long press (5s); increment with short press. |
| Function key / Reducing key | Enter into battery mode setting with long press (5s); decrement with short press. |
| ON/OFF | Single bond ON/OFF control. |
Working Mode Instruction:
| Icon | Working mode | Running state |
|---|---|---|
| 01 SET | The grid priority mode | Mains priority mode, after the device starts and the grid input under normal operation, the equipment through the grid bypass regulator to supply power to the load, at the same time power battery; When the grid is having too high/low/serious distortion or other abnormal, equipment will make battery energy through internal module transfer into high quality electricity and supply power to load. |
| 02 SET | Energy-saving mode | Under energy-saving mode, after the device starts, it will automatically detect load, when the load is greater than 5% rated power, the equipment starts AC output and power to the load; When detects no load, the device will automatically back to the search pattern, drop the battery energy consumption to lowest; This mode, equipment detects load every 10s, so as to achieve the purpose of energy saving. |
| 03 SET | Battery priority mode | Battery priority mode, the device started for the first time and the mains input under normal, equipment operation for mains priority mode, but no battery be powered. When the battery in the external charging device (such as solar charging system) after adequate power charged, equipment will automatically convert to battery energy through internal module into high quality electricity for load; When the battery power down to low voltage threshold, the equipment through the mains bypass regulator supply power to the load, but no power to battery. This pattern is mainly design for new energy power generation system design (such as wind and solar power system). |
Audible Alarm Reminder Instruction:
| Equipment running normal | Buzzing prohibit | Buzzer is no tweet under default state |
|---|---|---|
| Buzzer starts | Buzzer tweet 4 times every 15s, indicate the equipment operated under battery inverter state. | |
| Battery high voltage alarm | Buzzer tweets 4 times per second, alarms high voltage. | |
| Battery low voltage alarm | Buzzer tweets 2 times per second, alarms low voltage. | |
| Overtemperature alarm | Buzzer alarm 2 seconds pause 1 second. | |
5. Care and Maintenance
To ensure the longevity and optimal performance of your inverter, follow these maintenance guidelines:
- These products generally require minimal care. However, batteries need regular upkeep to achieve their expected lifetime.
- If the equipment will not be used for a long period, it is recommended to charge it once every 4-6 months. Batteries used for 3-5 years should be changed as soon as possible if any issues arise. When changing batteries, this must be performed by a professional and in accordance with the battery supplier's instructions.
- Before changing the battery, the equipment must be disconnected and isolated from the grid. Close the battery switch. Remove any metal objects such as rings from your person.
- When connecting the battery line, tiny sparks may occur at the joint. This is a normal phenomenon and will not cause harm to personnel safety. Never connect the battery positive and negative terminals in short circuit or reverse polarity.
