1. Charging i Current A CC Step CV Step Floating Step 2 3 Digital Display For high wattage inverter with charger such as 1000W and higher the front panel has digital display The Digital Display Shows the DC Voltage input that the unit senses at its terminals and the percent of the output wattage Protection Input protection A Battery polarity protection lf the battery input is connected in reverse polarity the internal fuse of the inverter will blow and the unit should be send back for repair and resetting B Battery Under Voltage shutdown When the battery voltage is lower than the preset value the unit will automatically terminate the output and thus protect the battery from damage C Battery Over Voltage Protection When the battery voltage is too high the unit will automatically terminate the output and the built in buzzer will be activated to inform the user After bypassing the OVP condition the unit should be repowered ON to resume operation ZI WARNING Choose suitable batteries that are compatible with the rated input DC voltage of the inverter If the input DC voltage is too low eg using 12V DC battery bank for 24V DC input models the inverter cannot be started up properly If the input DC voltage is too high eg using 48V DC battery bank for 24V DC input models the inverter will be damaged 3 2 Output protection The display panel will show failure status using red LED indicators when2. Make sure that suitable wires are chosen based on the current rating Too small of a cross section will result in overheating and could be dangerous B Requirements for Installation The unit should be mounted on a flat surface or holding rack with suitable strength In order to ensure the lifespan of the unit please refrain from operating in environments of high dust or moisture Please make sure that ventilation is not blocked and avoid long term operation within high ambient environment or continuous overloading There should be no barriers within 15cm of the ventilation holes Inverter ral C AV Important notice on output load This unit can power most equipment that needs an AC source however for certain types of load the unit may not work properly 1 Since inductive loads or motor based equipment need a large start up current 6 10 times the rated current the inverter may not start up successfully with these kind of load 2 When the equipment output is capacitive or rectified such as switching power supply it is suggested to operate this equipment at no load or light load during start up To ensure smooth power ON you should increase the load only after the unit has started up 5 Failure Correction Notes The unit should be serviced by a professional technician Any improper usage or modification may damage the unit or result in shock hazard If you are not able to clear the failure condition please contact us
3. unit is faced with abnormal operating conditions This alerts the user to potential problems 1 Over Temperature Protection When the internal temperature is higher than the limit value OTP will activate and automatically shut down the unit Users should wait for at least 30 minutes before restarting the unit 2 AC Output Abnormal Protection When the AC output voltage of the inverter is too low or too high the unit will turn off and should be restarted again 3 AC Output Short Circuit Protection When a short circuit situation occurs at the output side of the inverter or the loads increase greatly in a short period of time the unit will turn off and should be restarted again 4 Battery Voltage Abnormal Protection When the battery voltage is too high or too low this protection will be activated The inverter will auto recover after the battery voltage goes back to a safe level and a user restart is not required 5 Over Load Protection When the output is overloaded the inverter can still continuously provide power for several minutes After that if the overload condition is not removed overload protection will activate When the overload is too high the overload protection will be activated instantly For these overload protections once activated the unit must reset to recover 4 Installation amp Wiring A Wiring for Batteries Wire connections should be as short as possible and less than 1 5 meter is highly recommended
