The emergency stop button immediately disconnects the inverter from both grid and
battery, which ensure the safety of the inverter. By pressing the emergency stop
button, the device will be locked in the "off" position. Only release the emergency
stop button by rotating it clockwise and closing AC, DC breaker, can the inverter
resume working normally.
Figure 3-3-1-4 Off-on knob
It displays the inverter’s operating parameters, power generation, and faulty
information record. Please refer to Section 6, for details.
Off-on knob
It is used to start or stop the inverter.
Touch screen
3.4.1 ON-grid charge and discharge mode
3.4. Operation mode
There are several operation modes of the inverter.
CAUTION
When the ambient temperature is too high, it is normal the inverter
reduces the output power. However, if this frequently happens,
check the cooling surface of the inverter or place the inverter in
better ventilation conditions place. If the inverter fan is dirty, please
clean the fan, if there is problem with the inverter internal
electrical, please seek help from professional services.
3.4.3 Fault mode
When the DC power system fails, the inverter will immediately disconnect the AC
contactor and enters into the fault mode, so as to ensure the safety of the system.
Inverter continuously monitors fault status and will not enter charge and discharge
mode until the fault is eliminated.
3.4.4 Permanent fault mode
When the DC power system is in serious failure, the inverter will immediately
disconnect the AC contactor and enters into the Permanent fault mode, so as to
ensure the safety of the system. For example: inverter module failure etc. please
contact your local dealer or ATESS directly when inverter enters permanent fault
mode, repairmen on site is not allowed without authorization of ATESS.
Working procedure of PCS100 at on-grid charge and discharge mode:
1) PCS100 connected to battery on the DC side, and grid on the AC side;
2) Close the ac/dc circuit breaker and start-stop knob, PCS100 enter waiting status;
3) Start PCS100 via the LCD, it will start self-checking, once it fulfills on-grid
conditions, the energy storage controller will run in "on-grid charge“mode.
4) Click the "switch" button on the screen. You can complete the battery charge and
discharge state transitions. Charge current and discharge power can be set(default
20A charge, full power discharge).
3.4.2 Off-grid charge and discharge mode
At off-grid mode, PCS100 can work automatically, the inverter will sense the load
power and adjust its output automatically :
1) PCS100 connected to battery on the DC side, and load equipment on the AC side,
make sure grid is not connected;
2) Close the AC/DC circuit breaker and start-stop knob, PCS100 enter waiting status;
3) Start PCS100 via the LCD, inverter starts self-check, when self-check finished and
meet working requirement, inverter connects to local load.
4) inverter senses load power and adjust its output to supply local load equipment.
