1.Safety Guidelines (Please read through this manual before assembling the power inverter) ·Risk of electrical shock and energy hazard. All failures should be examined by the qualified technician. Please do not remove the case of the inverter by yourself. · please do not install the inverter in places with high moisture or near water. ·...
2.Product Introduction Inverter UPS is a combination of an inverter, battery charger and AC auto- transfer switch. Utility Priority: when the utility is present the inverter transfer this power to the household applicances (load) and uses what excess there is to charge the battery bank with its built-in charger.
3.1Front Panel Figure3.1 Front Panel ON/OFF Switch: This switch controls ON/OFF operation of the unit. Charger In: Plug AC input cable into it and AC source. AC Out: For application demands of different geographic areas all over the world,there are many different kinds of optional AC receptacle to choose from.
3.2 Rear Panel Fig 3.2: Rear Panel Fuse: Fuse was built-out is a very good design as you can very easy to change the fuse outside the inverter if your inverter fuse was blown. DC Battery Terminals: Connect the inverter to battery or other power source. Negative (-) and Positive(+) DC terminals should be kept insulated to protect from accidental short circuits.
⑶ Battery Over Voltage Protection:When the battery voltage is higher than the preset value, the inverter will automatically shut down and the buzzer alarm will sound 4 times. Fault light turns red at the same time. WARNING: Please choose suitable batteries that is compatible with the rated input DC voltage of inverter (refer to the SPEC).
Symptom Fault Messages Buzzer The normal starting of inverter: LED light turns green, indicating that the alarm is unit is operating normally. sounded 1 times Buzzer Overload protection: Fault LED light blinks, indicating that the load is 150% higher alarm is than rated power.
6.2 Suggested Battery Bank Capacity ·In according with the minimum safety starting ,full load discharge time and minimum configuration capacity, the users could choose battery bank of larger capacity (to meet the discharge time) to meet the requirement. ·Simple calculation of battery discharge time:Battery capacity / discharge current = discharge time eg:12V/220V/50Hz/300W full load of inverter100%...
6.5 Derating Figure 6.5.1 Output Derating Curve Figure 6.5.2 Input Derating Curve Notes on output load: The inverter can power most of equipments that need an AC source which can provide inverter continuously. But for certain load type, the unit may not work properly.
Status Possible Reasons Ways to Eliminate Abnormal Check the AC or DC input sources. Make sure the voltage is input within the required range. Over Make sure that the ventilation is not blocked or whether the temperature ambient temperature is too high. Please derating the output protection usage or reduce the ambient temperature.
