Use the battery in accordance with the manufacturer’s recommendations
Use the battery according to the connection rules provided by the manufacturer.
Incorrect operation may endanger you.
1. Do not short-circuit the wires. Links must be executed very tightly.
Do not simultaneously touch both battery terminals or wires connected to them.
2. Avoid extinguishing / boiling excess electrolyte.
Electrolyte is corrosive to metal, and is a short-circuit hazard.
3. Keep the battery safe, away from fire, or spark source.
Attention to the fans
Avoid accidental blocking of the fans.
Do not use tools or fingers to stop them.
Mount the equipment in a ventilated / ventilated area
Make sure that the intake / fan areas, and the air outlet are not obstructed in any way. Also, do not mount the
passive radiator part of the case attached to a wall, ceiling or floor, but to a distance that allows air to pass.
INSTALLATION
Check package contents
Check the following items when opening the package:
Check visually the inverter for bumps or inconsistencies.
If there are blows, or damaged housing contact the seller immediately.
Check the accessories shown in the package.
If you can not find all the accessories in the description, contact the seller immediately.
Installation conditions - environment
Keep the inverter in a dry and ventilated environment.
Keep the inverter away from moisture, dust, heat, sunlight, volatile or salty gas.
Cautions
The operating temperature of the product is between -26˚C ~ 50˚C.
Do not load the inverter to the maximum, at temperatures above 40˚C.
If you use the inverter excessively at temperatures above 40˚C, make sure you reduce the consumption by 10%
for each degree above 40˚C.
The optimal operating temperature of the inverter is between 20˚C ~ 30˚C.
If it is used at temperatures above 30˚C, battery life will drop considerably.
Less than 20˚C will reduce the electrical accumulation time.
Use - safety distances
The inverter must be installed at least 60mm away from the surrounding walls, with the freezer top and side
radiator. Do not cover the side panels of the inverter to provide cooling efficient, and to avoid overheating.
Connecting electrical cables
Cautions
Make sure the power switch of the inverter is set to OFF.
Observe the polarity of the wires, and do not connect backwards to avoid short circuiting the inverter.
Follow the following steps to connect the inverter cables:
1. Turn off the inverter from the ON / OFF button.
2. Connect the wires respecting the polarity at the battery terminals
3. Ensure that the two cables are tightly connected to avoid overheating.
4. Connect the consumers to the Schuko Outlet socket on the side panel of the inverter.

5. After making sure that all connections are made correctly and well, turn on the inverter. If the green LED
lights up, it means that the Output Voltage is correct, and the inverter is working properly.
The correct connection of the inverter is shown in the following diagram.
1. Do not use the inverter’s AC output to connect to the 230V national grid, so as not to burn the inverter.
2. Connect the consumers gradually, and do not exceed the declared maximum power of the inverter.
3. For inductive loads, choose an inverter with a maximum power of 2-3 times greater.
4. It is recommended to start the car only with the inverter off, because this procedure will consume a lot of
power and can affect the inverter.
5. The inverter must be mounted in a ventilated place, not covered, and away from people’s access.
6. Do not connect the inverter to discharged, damaged or aging batteries, as it may cause the inverter to
burn.
Installation conditions - environment
1. Keep the inverter in a clean and airy place.
2. Avoid inverter contact with sun, water, humidity, mud, or mist.
3. The operating temperature is between -26˚C ~ 50˚C
BATTERY
Battery features
1. Capacity: Represents the amount of energy at maximum power composed of the multiplication current with
the discharge time.
Capacity = Discharge current (I) x Discharge time (H)
2. Download Rate: Represents the speed of each discharge current
3. Discharge current: The discharge current is the output current. It is usually expressed in amps or volume
multiplied by a coefficient.
4. Final Discharge Voltage: Represents the voltage when the battery is not discharged.
Typically it is about: 1.75V / cell.
5. Nominal Capacity: Represents capacity after 20 hours of unloading.
6. Self-discharge rate: The battery is discharged even when not in use. The unit is: C / unit.
Because inverters need a strong current, when operating, battery capacity and maximum current are factors
that determine the efficiency of the inverter (50% - 100%). These factors can also cause damage to the battery.
The storage capacity of the battery depends on the maximum discharge current.
EN

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
Possible cause
Solution
The inverter does not turn on and
the Power LED does not turn on
1. Battery is damaged or damaged
2. The battery connection is
abnormal
3. Safety is burned
1. Replace the battery
2. Connect the battery carefully
3. Change the safety
The inverter is in protection and
the red LED (Fault) turns on
1. The inverter enters the
protection when the total of the
consumers exceeds the rated
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.
1. Reduce the number of
connected consumers and restart
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.
