WARNING: Suitable for mounting on concrete or other non-combustible surfaces only.
Install the unit by screwing three screws: use M6*80mm expansion bolts for points 1 and 2, and M4 or M5 for point 3.
4.3 Battery Connection
CAUTION:
- For safety and regulation compliance, install a separate DC over-current protector or disconnect device between the battery and inverter.
- All wiring must be performed by qualified personnel.
- Use appropriate cable for battery connection to reduce risk of injury.
Refer to the table below for recommended battery cable and terminal sizes. Assemble battery ring terminals, insert battery wires flatly into inverter connectors, and ensure bolts are tightened to 2 Nm. Verify correct polarity at both the battery and inverter/charger.
| Model | Typical Amperage | Battery Capacity | Wire Size | Ring Terminal Dimensions (D/L mm) | Torque Value |
|---|---|---|---|---|---|
| 2KVA | 88A | 100AH | 1*6AWG / 2*10AWG | 6.4/33.2 / 6.4/23.8 | 2~3 Nm |
| 3KVA | 132A | 200AH | 1*4AWG / 2*8AWG | 6.4/33.2 / 6.4/29.2 | 2~3 Nm |

WARNING: Be sure the length of all battery cables is the same. Otherwise, there will be voltage difference between inverters and batteries, causing parallel inverters not to work.
4.4 AC Input/Output Connection
CAUTION:
- Install a separate AC breaker between the inverter and the AC input power source. This ensures the inverter can be disconnected during maintenance and is protected from over-current. Recommended breaker specs: 32A for 3KW, 50A for 5KW.
- Do not mis-connect input and output connectors. There are two terminal blocks with "IN" and "OUT" markings.
- All wiring must be performed by qualified personnel.
Refer to the table below for suggested AC wire requirements. Before making connections, open the DC protector or disconnector. Remove 10mm of insulation from conductors and shorten phase L and neutral conductor N by 3mm.
| Model | Gauge | Torque Value |
|---|---|---|
| 2KVA | 14AWG | 0.8~1.0Nm |
| 3KVA | 12AWG | 1.2~1.6Nm |
| 3.6KVA | 12AWG | 1.2~1.6Nm |
| 5KVA | 10AWG | 1.4~1.6Nm |
| 5.5KVA | 10AWG | 1.4~1.6Nm |
| 6.2KVA | 10AWG | 1.4~1.6Nm |
| 8KVA | 8AWG | 1.4~1.6Nm |
| 11KVA | 8AWG | 1.4~1.6Nm |
WARNING: Be sure all output N wires of each inverter must be connected all the time. Otherwise, it will cause inverter fault in error code #72.
4.5 PV Connection
CAUTION:
- Before connecting to PV modules, install a separate DC circuit breaker between the inverter and PV modules.
- All wiring must be performed by qualified personnel.
- Use appropriate cable for PV module connection.
Refer to the table below for suggested PV wire requirements. When choosing PV modules, ensure the open circuit voltage (Voc) does not exceed the maximum PV array open circuit voltage of the inverter. The maximum supply voltage should be close to the optimal PV access voltage range for best performance. If one PV module cannot meet this requirement, connect multiple PV modules in series.
| Typical Amperage | Gauge | Torque Value |
|---|---|---|
| 30A | 12AWG | 1.4~1.6Nm |
4.6 Final Assembly
After connecting all wirings, put the bottom cover back by screwing the two screws. Then, put the wire cover back to the unit.
4.7 Communication Connection
The inverter supports communication with a PC, Wi-Fi cloud, and GPRS cloud. For detailed instructions on setting up monitoring software or apps, refer to the specific guidelines provided with the communication modules (e.g., "Wi-Fi Plug Quick Installation Guideline" or "GPRS RTU Quick Installation Guideline").

5. Operation
5.1 Power On/Off
Once the unit is properly installed and batteries are connected, simply press the On/Off switch (located on the button of the case) to turn on the unit.
5.1.1 Steps to Start Up
- Connect the battery (voltage needs to be beyond 23V) or AC (AC needs to confirm the suitable input range depending on the output mode).
- Mains power on: Connect to normal AC power, press the switch. The system will automatically turn on. If AC output power priority is set, the panel will display AC mode after a period, indicating successful startup.
- Battery boot: Connect to battery, press the power-on button. The system will automatically turn on. After a period, the panel will display battery mode, indicating successful startup.
5.1.2 Shutdown Steps
When the system is in battery mode or AC mode output, press the switch again to turn off the unit.
5.2 Operation and Display Panel
The operation and display panel on the front of the inverter includes an LCD display, three LED indicators (AC/INV, CHG, FAULT), and four function keys (ESC, UP, DOWN, ENTER). These indicate the operating status and input/output power information.

| LED Indicator | Status | Message |
|---|---|---|
| AC/INV | Green Solid On | Output is powered by utility in Line mode. |
| Green Flashing | Output is powered by battery or PV in battery mode. | |
| CHG | Green Solid On | Battery is fully charged. |
| Green Flashing | Battery is charging. | |
| FAULT | Red Solid On | Fault occurs in the inverter. |
| Red Flashing | Warning condition occurs in the inverter. |
| Function Key | Description |
|---|---|
| ESC | To exit setting mode. |
| UP | To go to previous selection. |
| DOWN | To go to next selection. |
| ENTER | To confirm the selection in setting mode or enter setting mode. |
5.3 LCD Setting and Display
Press and hold the ENTER button for 3 seconds to enter setting mode. Use UP/DOWN buttons to select programs and ENTER to confirm. The LCD display cycles through various information such as input voltage, frequency, PV voltage, charging current, battery voltage, output voltage, output frequency, load percentage, load in Watt/VA, DC discharging current, and firmware versions.
5.4 Battery Equalization
The inverter includes a battery equalization function to reverse the buildup of negative chemical effects like stratification and to remove sulfate crystals. It is recommended to equalize batteries periodically.
5.4.1 When to Equalize
The controller will enter the Equalize stage when the setting equalization interval is reached or when equalization is actively initiated. The battery will remain in this stage until the set equalized time is reached.
5.4.2 Equalize Charging Time and Timeout
During equalization, the controller charges the battery until it reaches the equalization voltage. If the battery voltage does not reach the equalization voltage within the set equalized time, the controller will extend the charging time until the voltage is achieved. If it still doesn't reach the voltage after the timeout, equalization will stop and return to float stage.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your DATOUBOSS Hybrid Solar Inverter. Always disconnect all power sources (AC, DC, and battery) before performing any maintenance.
- Cleaning: Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow and prevent overheating. Use a soft, dry cloth for cleaning the exterior.
- Connections Check: Periodically inspect all electrical connections (battery, AC input/output, PV input, communication ports) for tightness and corrosion. Tighten any loose connections and clean any corrosion.
- Battery Inspection: Check battery terminals for corrosion and ensure battery cables are in good condition. Monitor battery voltage and performance regularly.
- Firmware Updates: Check the manufacturer's website or contact support for any available firmware updates to ensure optimal performance and access to new features.
- Environmental Check: Ensure the inverter is operating within the recommended temperature and humidity ranges.
WARNING: Only qualified personnel should perform maintenance that involves opening the unit or working with internal components.
