| Introduction |
Utility Priority |
When utility power is available, the inverter will transfer this power to the household applicances (load). When utility power is disconnected, the inverter will switch back to invertering from the batteries without disrupting the power going to the appliances. |
| Battery Priority |
When inverter output is available, output as invertering is priority. When inverter output is unavailable, this unit will transfer to utility, the utility supply AC to equipments. |

| 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 |

| 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 |
|
