2.Wiring Inspection
After finishing wiring all of the input/output cables, the following should be inspected:
(1) whether the order of the phases is correct;
(2) whether battery input cable is connected with the correct polarity;
(3) whether the ground connection cables of the Input and Output have been connected to the terminal board
firmly.
Notice: The Bypass input cables (R,S,T) and the Rectifier input cables (R,S,T) are paralleled connected.
A.Procedures of Switching on Single Machine
Please switch on the inverter according to the following procedures after wiring all of the necessary cables
properly
1. Close up the input switch of rectifier to start the rectifier of the inverter after confirming that all the phases
have voltage;
If no display on the LCD screen, and there's long buzzes, it indicates that the input phases are not in correct order;
then rectifier switch should be turned off and input power bus should be disconnected until the input phases
(R,S,T) are wired in correct order;
Close up the rectifier switch again and LCD screen shall have display. Then it takes around 30s for
self-inspection before starting the inverter;
The spinning fans indicate that the inverter has started up .
2. The Battery Switch can not be closed up until the inverter has started;
3. Close up the Bypass Switch;
4. Close up the Output Switch.
Note: When the inverter is working normally, the Repair Switch should be disconnected, otherwise the
mains power would go through repair switch directly to the loads.
III.Operation of the Inverter -1
6th
B.Procedures of Regular Switching Off
1. Disconnect the output switch;
2. Disconnect the Bypass Switch;
3. Disconnect the Battery Switch;
4. Disconnect the Rectifier Input Switch;
5. Disconnect the main power switch.
Warning:
1. Please strictly follow the above procedures to turn off the inverter;
2. The above actions should be done continuously until all of the switches are disconnected.
B.Mains priority
AC first , DC standby INVERTER mode
When both utility and battery are connected to the machine, utility will supply power to the loads prior to the battery. When
utility is cut off, the battery will automatically continue to supply power.
Step 1: When utility power is available, it will output directly after voltage being stabilized and charge batteries at the same
time.
Step 2: When utility power is cut off suddenly, the inverter will convert
DC power to AC power automatically to ensure uninterrupted power supply within 5ms.
Step 3: When utility power becomes available again, it will automatically transfer to utility supplying power to loads and
charge batteries at the same time.
See Workflow as below:
B.Battery priority
DC first, AC standby:
When both utility and battery are connected to the inverter, battery will supply power to the loads prior to utility.
When battery capacity is not enough, utility will continue to supply power automatically.
Steps are as follows:
Step 1: When battery has enough power, it will supply power to the loads directly
Step 2: When battery does not have enough power, it will automatically transfer to utility supplying power to the
loads
IV.Operation of the Inverter -2
7th
Step 3: After the battery is fully charged (e.g. by solar or wind charge controller), it will then automatically transfer
to battery supplying power to the loads.
See Workflow as below:
Note: Battery supporting time would be affected by the power consumption of the loads and
temperature. Removing some of the loads can extend battery time.
Under the battery mode, the alarm would buzz interruptedly, and the indicators of Output and Battery on
the control panel would show green light.
The closer to the exhaustion of the batteries, the more frequent would the buzzers go, with battery
indicator flashing at the same time. Inverter will stop working when the batteries exhaust until the
power come back for supplying and charging the batteries.
C.Static Bypass Mode
The inverter will turn to Static Bypass mode under any of the following situations:
1. order of transfer to Bypass (manually or automatically);
2. Output over-loaded;
3. Fault.
Under this mode, the bypass LED indicator on the control panel (Yellow light) will light on.
Note: The static bypass switch should be synchronized with AC power; It can be manually or
automatically set to 0 transfer time from protective load (inverting output) to non-protective load (Bypass
output)
8th
D.Reparing Mode
Used when the inverter needs repairing without cutting the power for the loads.
When Repair Switch is closed, the control panel stops displaying, and eletricity goes from bypass route to the
load and the load will be affected by any interference on the power grid.
Batteries cannot supply the power for loads; Shown as the Graph 8
Note: Before repairing the machine, manually close up the Repair Switch and disconnect all the other
switches (Input Switch, Output Switch , Battery Switch and Bypass Switch). Then apart from the voltage
on the switch part, there's no current going through the internal components of the inverter and the loads
are still having power supply.
But non-qualified personnel is not allowed to use the Repair Switch.
E.SLU
All of the operation action of this inverter is controlled by DSP chip.
F.Battery
It supplies the power for inverter. Choose battery quantity and capacity according to the type of the
inverter and the required back-up time.
G.Turn to Bypass with Inverter's Off
Under the normal situation, if the orders to turn off the inverter part, the loads will be supplied by power from
static bypass. If the mains power fails, the loads will not have power supply.
Under the emergency situation, if the inverter receives order of turning off the inverter part, the inverter will shut
down completely until the power getting back to normal, then it will start the normal working mode automatically.
Note: Since Input Switch and Battery Switch shall have voltage remains even they are disconnected, only
qualified personnel is permitted to repair the inverter. Otherwise the inverter may be damaged or worse,
accidents occurs to human being.
A.Periodically Maintenance
Batteries and cooling fans are the items that should be inspected periodically.
1. Inspect the cooling fans and clean its dust;
2. Replacing the batteries should be done by qualified personnel. All the disused batteries should be returned to
the related re-collection institute as the disused battery is deemed to be "Poisonous Waste".
V.Maintenance
9th
3. Battery life is related to the designed cycles of charging-discharging and the working temperature. Usually,
under 20 ℃, battery life can be 3~5 years. If the environmental temperature of the battery is above 30 ℃, battery
life would 1.5~2.5 years.
After a few times of charging-discharging cycles, the battery capacity would increase and be stable for the next
hundreds of cycles. Then it will shrink.
B.Battery Maintenance
Battery maintenance should be executed as follows:
1. Keep the environment temperature at around: 20~25 ℃;
2. In the first month, 2~3 times of charging and discharging the batteris is advised;
3. After the first month, batteries should be charged and discharged once every 3 months.
