INSTALLATION GUIDE
STEP1 Mounting the Unit Selecting a proper placement in a wall with a clearance of approx. 200mm above and below the unit, ensure the heat dissipation. Install the unit with four screws which are already provided by the packaging with the unit. For safety operation and regulation compliance, please install a circuit breaker or fuse between each power source, and must trip the breaker before connecting.
WARNING! Ventilation is very important to lead-acid batteries, Otherwise, there is a risk of batteries explosion.
WARNING! Never operate in a wet or dusty environment.
CAUTION! Local rules and regulations should be followed when installing this unit.
STEP2 Connection Take off the terminal cover by moving two screws.
Please follow the below steps to implement the connection:
- PV connection Insert PV IN cables according to polarities indicated on the terminal block which shown as below.
- Battery connection Insert BAT+/- cables according to polarities indicated on the terminal block which shown as below. 5mm diameter round terminal block required for battery cable connection.
- AC IN/OUT connection Insert AC IN/OUT cables according to polarities indicated on the terminal block which shown as below. Its AC output terminals must be provided with grounding, be sure to connect PE first. An additional grounding point is located on the outside of the product.
WARNING! To reduce the risk of fire, please use the proper recommended cable and terminal size in the user’s manual.
CAUTION! The terminal screws must be tightened to reduce heat generation due to resistance.
STEP3 Final Assembly
Put the terminal cover back and screw.
Operation
- Closing the breaker between the battery and inverter.
- Press the ON/OFF switch at the bottom, the corresponding icons will be displayed on the panel.
- Closing the breaker between the PV array and the inverter, the corresponding icons will be displayed on the panel.
- Closing the breaker between the utility grid and between inverter, the corresponding icons will be displayed on the panel.
- Finally, turn on the load and see if it runs smoothly.
TROUBLESHOOTING
The common fault codes are shown below:
NOTE: For fault codes that do not appear in this table, please check in the user manual.
Fault
codes

Definition
|
Cause
|
Remedy
[03]|
Battery Disconnection
|
Battery disconnection or Li-ion battery BMS can’t smooth communication
| 1. Please check if battery cables are connected well.
2. Please check if circuit breaker is opened. 3.Please check if BMS wire of Li-ion battery is connected well.
[09]|
PV Input Overvoltage
|
The total voltage of the serially connected PV modules exceeds the permitted value of the device.
|
Use a multimeter to check if the open-circuit voltage of the PV array exceeds the maximum allowable input open-circuit voltage, if so, then reduce the number of PV modules in series.
[21]|
Fan Fault
|
Fan failure more than 3s.
|
After switching off all power, check the fan for foreign objects stuck in ii.
[43]|
Parallel Connection Error
|
A high level signal input is detected in the parallel communication cable.
|
1. lf you use multiple HFP series inverters, Please check if the DB15 cable is connected well.
2. lf you use only a single inverter for the HFP series, please set the item of 31 to SIG.
