3000W 24VDC to 220VAC High frequency EPEVER Pure Sine Wave Inverter SPWM Technology Switched Output Voltage and Frequency
Features
Complete isolation-type inverter technology.
Adoption of advanced SPWM technology, pure sine wave output.
Dynamic current loop control technology to ensure inverter reliable operation.
Wide DC input voltage range.
Low output harmonic distortion (THD≤3%).
LED indicators for input voltage range, load power range, normal output & failure state.
Optional energy saving mode.
The output voltage and frequency can be switched.
Extensive protections: short-circuit, overload, under/over input voltage, over-temperature, and inverter’s inner fault identification protections.
Wide working temperature range (industrial level).
Continuous operation at full power.
As an AC power supply equipment, the inverter’s output voltage is with the same level as that of household power plug. Mind the AC output terminals, or you may get an electric shock and result in life danger!
Attentions:
Connect the DC input according to the requirement strictly. The power inverter has a relatively wide input range, but too high or too low input may cause problems even destroy the inverter. The surge input voltage can’t exceed 40V for 24V inverters, 80V for 48V inverters, or the inverters will be damaged.
A reverse polarity connection will blow the fuses in the inverter and may damage the unit.
Do not expose the inverter to humid, flammable, explosive or dust environment.
Keep the inverter out of children touch.
Inverter input is recommended to connect to battery, the min. capacity of battery(expressed in AH) should be calculated in the following way: 5times of the rated power of the inverter/battery voltage. If for testing purpose, user should select DC power supply current at least twice greater than that of the inverter rated input to keep inverter normal operation. Use DC power supply for testing may cause the damage of the inverter.
When the inverter works continuously, its surface may became very hot, please make sure the air ventilation clearance around the inverter is more than 10cm. Keep away from the material or device which may suffer from high temperature when the inverter is working. Do not install the inverter in airproof location and keep enough space around the inverter.
The protective grounding must be connected to the ground. The cross section of wire should not be less than 4mm2.
A fuse or breaker should be used between battery and inverter, the value of fuse or switch should be twice of the inverter rated input current.
The wire connects between battery and inverter should be shorter than 3m, the current density should be less than 3.5A/mm2 while the output of inverter is fully loaded. If the wire longer than 3m, the current density should be reduced.
Do not connect the battery charger or similar devices to the input terminal of the inverter.
Do not put the inverter close to the flooded lead-acid battery because the sparkle in the terminals may ignite the hydrogen released by the battery.
It’s an off-grid inverter, do not connect the AC output terminals to the grid or electrical source, otherwise the inverter may be damaged.
This inverter can only be used singly, parallel connection or in series will damage the inverters.
Risk of electric risk, don’t touch output port when the inverter is working. The output is forbidden to connect other power, otherwise the inverter will be damaged. The inverter must be in off, when connecting load.
Do not attempt to repair the fault inverter yourself, otherwise it may lead to a serious accident. Please contact the manufacture’ s engineer.
Connect the input and output terminals accurately. Turn on the power using the ON / OFF switch on the front panel. In order to avoid the protections resulted from the surge power, please turn on AC loads one by one after the output of the inverter is normal. Please check it as below:
Set the power switch to the ‘OFF’ position. Insert the load’s plug into the inverter’s output outlet.
Connect the protective grounding to the ground.
Make sure the fuse or breaker use between battery and inverter is off.
Connect the battery (‘+’ terminal with red line, ‘-’with black line). Do not connect them by contraries, or the power inverter will be damaged.
Switch on the fuse or breaker. Switch the inverter to ON and then turn on the loads one by one. Check the operation state of both power inverter and loads. ‘Green’ of the failure LED indicator means the state is normal.
If there are different loads, it is suggested that turn on the load with large startup current first, such as television, then turn on the load such as lamp when the inverter works stable.
If the failure LED indicator is ‘Red’ and the buzzer alarms or no output when you turn on devices, switch off the loads and power inverter immediately. Check the system by referring to the troubleshooting guide. Turn on the devices again according to the operation methods after the failure is removed.
