DC Side Connection Requirements
WARNING
The VOLFVERT pure sine wave inverters are suitable for 24V battery bank systems only. not following the minimum DC requirement will cause irreversible damage to the unit.
CAUTION
Be careful of the positive and negative poles. Reversing the poles might cause permanent damage to the inverter. It will surely blow the internal fuse.
NOTE
The input terminals of the inverters have large capacitors connected to them. Once a positive and negative wire are connected to the terminals, it will complete the circuit, and commence drawing a heavy current momentarily. As a result, there may be a sparking occurring even if the inverter is in the off position. To minimize sparking, it is recommended that the user have the appropriate size wire feeding into the inverters and/or install an external fuse leading into the inverter.
SECURE CONNECTION OF THE INVERTER
a. NEGATIVE: Connect one side of the provided Negative(BLACK) DC cable to the Negative(-) bolt of the inverter,and the other side to the Negative(-)post of the battery.
b. POSITIVE: Connect one side of the provided Positive(RED) DC cable to the Positive(+)bolt of the inverter, and the other side to the Positive(+)post of the battery.
c. The nuts of the connection posts must be tightened to ensure a good connection.
d. SWITCH BUTTON: Please note that the switch has 3 gears. From top to bottom are on, off, and remote.
e. The inverter will shutdown automatically if connection reversed.Irreversible damage to the machine cannot be excluded which will affect your warranty.
Battery Bank Requirements
The battery is for supplying DC input voltage to the inverter. Its rated voltage should be the same as the rated input voltage of the VOLFVERT inverter. Any voltage that exceeds the input voltage range of the inverter will cause the inverter to be overloaded and may damage the inverter.
The battery ought to supply enough current for the load. (The load is the amperage or wattage rating of the equipment being powered by the inverter.) A small capacity battery cannot supply enough power for large electrical equipment and it will cause the inverter to be under-voltage.
SIMPLE METHOD
For determining the required battery capacity size is shown below for reference:
1. Determine the Watts (Amps Volts) of the load required for operation.)
2. Utilize the formula Amps=Watts/ Volts
(Each appliance has technical specifications indicating the wattage or voltage and amperage
3. Inverter consumption=Amps10%
(Due to inverter efficiency 90%,the recommended estimate for the calculation is 10%)
4. Estimated load runtime
(The capacity of the battery depends on the load wattage and runtime. Most loads are not constant, so estimation is essential.)
5. Determine Ah(Ampere-Hour) of the battery
Example: Using 24VDC battery to run a 2400Watts Air Conditioner for 2 hours needs at least 220Ah battery. (10%Inverter consumption)
The calculations are as follows:Utilize the formula Amps=Watts/ Volts| 2400 Watts / 24 Volts = 100Amps
---|---
Inverter consumption| 100 Amps × 10%= 10 Amps
Load runtime = 2 hours| (100 Amps+10) × 2 hours = 220 Ah

Conclusion: At least a 220 Ah battery must be selected in order to use the 24 Air Conditioner at 2 hours a day. However, determining the capacity of the battery also depends on the battery that is able to handle repeated discharge/charge cycles.
This is just an example. Actual quantities vary by battery capacity and rates.
Running wattage may fluctuate.To power the Air Conditioner in the example, must use an inverter of at least 2500 watts.

Grounding Requirements
The VOLFVERT Pure Sine Wave inverters come equipped with a ground terminal to appropriately ground to earth or to another designated ground. (for example, a metal frame of an RV).
The connections to ground must be tight and against bare metal. Whether using the inverter in a mobile application, such as an RV, or in a building, grounding is highly recommended.

RECOMMENDATION
The recommended wire size for grounding is 14AWG or larger insulated copper strand wire.
For more information regarding grounding, users and/or installers must consult with the Local and National Electric Codes (NEC) for more specific grounding regulations and suggestions as they can change per scenario.

⬛ Operation Safety
Assuming proper battery connection, the inverter is now ready for use.

AC Side Operation
a. Connect electronic devices to electrical socket(s) on inverter. Flip inverter power to ON position (on AC side)
b. When finished, switch AC devices off FIRST, then turn off inverter switch
CAUTION
Make sure that the switches of the inverter and appliance power are in OFF position before connection.
When switching off the Inverter, turn off the electronic devices first. Although the Inverter Is off, the capacitors will still have a charge, so the DC and AC terminals must be disconnected If altering the circuitry.
c. Connection of heavy duty
For the appliances with a load more than the limit of AC outlet ,please connect to the Hard Terminals Blocks, make sure the ground terminal of inverter connected with ground terminal of appliance.

⬛ Use Safety
