Troubleshooting And Maintenance - PNI H1200W - 24V Manuel D'utilisation

Sizing the battery correctly
Maximum discharge current = Rated power / (storage voltage * 0.93)
Battery storage capacity = average discharge current * discharge time
Example: PNI H1200W has a rated output of 1200W, input voltage 24V, so:
Average discharge current = 1200 / (24 * 0.93) = 54 A
If it's used for 2 hours:
Battery storage capacity = 54 * 2 = 108 Ah
Choose a 24V battery with a capacity of more than 108 Ah

TROUBLESHOOTING AND MAINTENANCE

Maintenance
We recommend regular maintenance of the product for extended life.
1. Avoid the hostile environments in which it is mounted: humidity, gas, mess, overheating, mechanical /
physical shocks.
2. Regularly check cables, connections, and aging.
3. Cleaning the fans, and periodically checking the functionality.
Troubleshooting
Error
The inverter does not turn on and
the Power LED does not turn on
The inverter is in protection and
the red LED (Fault) turns on
Possible cause
1. Battery is damaged or damaged
2. The battery connection is
abnormal
3. Safety is burned
1. The inverter enters
protection when the total of the
consumers exceeds
power of the inverter.
2. The starting power of the
consumers is higher than the
declared peak power for the
inverter. The inverter enters the
protection.
3. The battery voltage is too low.
The inverter triggers protection
from under-voltage.
4. The battery voltage is too
high. The inverter triggers the
overvoltage protection.
5. Inverter temperature too high.
6
1. Replace the battery
2. Connect the battery carefully
3. Change the safety
the 1. Reduce
connected consumers and restart
the rated the inverter.
2. Inductive consumers
(motors, pumps) have a very high
start-up consumption. Choose an
inverter with a rated power of 4-5
times higher in these cases. (or
change the battery)
3. If the battery voltage rises above
the minimum level of protection,
the inverter automatically restarts.
4. If the battery voltage drops
below the maximum protection
level, the inverter automatically
restarts (or changes the battery).
5. Close the inverter for 15
minutes, check and clean the
ventilators and side ventilation
holes, and keep ventilation space
around the housing.
