| Transfer time AC to inverter and inverter to AC |
less than 30ms |
| Remote Control |
Cable length: 5m cables |
| Power-Saving mode |
The power saving mode will be activated when the output power is less than 5W. When output power is more than 10W, the inverter will automatically return to normal status. |
| Ignition Function |
Connect vehicles battery (or connect positive pole of vehicles' STARTER). The inverters start simultaneously When the vehicles start; The inverters will shut down meantime when the vehicles shut down. |
| Protection Function |
Low voltage alarm |
code: F05 |
Buzzer sounds and fault light turns red |
| Low voltage shutdown |
code: F01 |
Recover by hand after the inverter shutdown. (the inverter will auto recover when the battery voltage go back to a normal level within 20ms.) |
| Over input voltage protection |
code: F02 |
Recover by hand after the inverter shutdown. (the inverter will auto recover when the battery voltage go back to a normal level within 20ms.) |
| over load alarm |
code: F06 |
Buzzer sounds and fault light turns red when output power is overloaded around 110%. But the BUZZ and F06 code will not occured when the output power drop to a normal level within 20ms. |
| Over load protection |
code: F03 |
The inverter shutdown when output power is overloaded around 120%, it need to be recovered by hand. |
| Over temperature alarm |
code: F07 |
Buzzer sounds and fault light turns red when the inverter's internal temperature is higher than the limit value (90±5ºC). |
| Over temperature protection |
code: F04 |
The inverter will automatically return to normal status when the internal temperature drops to 80±5ºC. |
| |
code: F08 |
The display will show the code F08 when the thermostat in the inverters is broken |
| Short circuit protection |
code: F03 |
Recover by hand |
| Reverse polarity protection |
|
Built-in fuse |
| AC input overload protection |
code: F09 |
The fan will start to work when the relay temperature is up to 60±5ºC; but it will stop to work when the relay temperature drops to 50±5ºC. The unit will alarm, and no AC output when relay temperature is up to 75±5ºC; But it will auto recover when the relay temperature drops to normal value. |
