Installation Safety

1. Placement Requirements

Ensure adequate space and follow guidelines for installation.

WARNING

• NEVER install the inverter in a sealed enclosure with flooded batteries due to explosion risk from gas accumulation.
• NEVER mount the inverter vertically on a vertical surface, as this obstructs the fan opening, potentially shortening its life and causing other dangers.
• NEVER mount the inverter upside down.
• The VOLFVERT Inverter should be placed horizontally.
• Well-ventilated area: Allow at least 12 inches of clearance around the inverter to prevent blocking vents and ensure adequate air circulation.
• Dry area: Keep the inverter away from liquids and moisture.
• Cool area: Ensure fans are not blocked. Do not place the inverter in direct sunlight or near heat sources. Maintain ambient temperature between 32-104°F (recommended 50-77°F).
• Low dust area: Avoid environments with high dust, sawdust, or other particles that could be sucked into the inverter, increasing internal temperature.
• Close proximity to battery bank: Install the inverter close to the battery bank with appropriately sized wiring to prevent excessive voltage drop.
• Protection against fire hazard: Keep the unit away from flammable materials, liquids, gas, or combustible materials due to potential electrical arcing or sparks when connecting to the battery.
• Separate compartment from battery: Do not install the inverter in the same compartment as the battery bank to avoid potential fire hazards.

CAUTION

Keep the machine and surrounding environment hygienic to prevent damage from insects like cockroaches.

RECOMMENDATION

Mount the inverter on a stable surface (floor, table, or support) to prevent bouncing. Ensure the mounting location can support the inverter's weight. Secure with four screws.

SPECIAL NOTES FOR CHILDREN

• NEVER allow children to use the inverter.
• NEVER install the unit where children can access it. Keep it out of reach of children.
• Place accessories in locations not easily accessible to children, as they can cause harm.

2. DC Side Connection Requirements

WARNING

The VOLFVERT pure sine wave inverters are suitable for 12V battery bank systems ONLY. Failure to meet the minimum DC requirement can cause irreversible damage.

CAUTION

Be careful with positive and negative poles. Reversing polarity may cause permanent damage and blow the internal fuse.

NOTE

The inverter's input terminals have large capacitors. Connecting the positive and negative wires completes the circuit, drawing a heavy current momentarily, which may cause sparking even when the inverter is off. To minimize sparking, use appropriately sized wires and consider installing an external fuse.

SECURE CONNECTION OF THE INVERTER

• NEGATIVE: Connect one end of the provided Negative (BLACK) DC cable to the inverter's Negative (-) bolt and the other end to the battery's Negative (-) post.
• POSITIVE: Connect one end of the provided Positive (RED) DC cable to the inverter's Positive (+) bolt and the other end to the battery's Positive (+) post.
• Ensure the nuts of the connection posts are tightened for a good connection.
• SWITCH BUTTON: The switch has three positions: ON, OFF, and REMOTE (from top to bottom).
• The inverter will automatically shut down if the connection is reversed, potentially causing irreversible damage and voiding the warranty.

3. Battery Bank Requirements

• The battery supplies DC input voltage to the inverter. Its rated voltage must match the inverter's rated input voltage. Exceeding the input voltage range can overload and damage the inverter.
• The battery must supply sufficient current for the load (amperage or wattage rating of the powered equipment). A small capacity battery may not provide enough power for large equipment, leading to under-voltage.

SIMPLE METHOD for determining battery capacity:

1. Determine the Watts (Amps * Volts) of the load. Check appliance specifications for wattage and amperage requirements.
2. Calculate Amps = Watts / Volts.
3. Inverter consumption = Amps * 10% (estimated due to 90% inverter efficiency).
4. Estimate load runtime based on battery capacity and load wattage. Note that most loads are not constant.
5. Determine the required Ah (Ampere-Hour) of the battery.

Example: Running a 1200 Watts hotplate for 2 hours using a 12VDC battery requires at least a 220Ah battery (including 10% inverter consumption).

Calculations:

• Amps = 1200 Watts / 12 Volts = 100 Amps
• Inverter consumption = 100 Amps * 10% = 10 Amps
• Load runtime = (100 Amps + 10 Amps) * 2 hours = 220 Ah

Conclusion: A minimum 220 Ah battery is recommended for 2 hours of use daily. Battery capacity should also consider its ability to handle repeated discharge/charge cycles.

*Actual quantities may vary by battery capacity and rates.

*Running wattage may fluctuate. For the example hotplate, an inverter of at least 1500 watts is required.

4. Grounding Requirements

• The VOLFVERT Pure Sine Wave inverters have a ground terminal for grounding to earth or another designated ground (e.g., an RV's metal frame).
• Ground connections must be tight and against bare metal. Grounding is highly recommended for both mobile applications (like RVs) and buildings.

RECOMMENDATION

Use 14AWG or larger insulated copper strand wire for grounding. Consult Local and National Electric Codes (NEC) for specific regulations, as they can change.

Operation Safety

Assuming proper battery connection, the inverter is ready for use.

1. AC Side Operation

• Connect electronic devices to the inverter's AC socket(s). Flip the inverter power switch to the ON position (AC side).
• When finished, turn OFF the AC devices FIRST, then turn OFF the inverter switch.

CAUTION

• Ensure the inverter and appliance power switches are OFF before connecting.
• When turning off the inverter, turn off electronic devices first. Capacitors may retain a charge even when the inverter is off; disconnect DC and AC terminals if altering circuitry.

c. Connection of heavy duty

For appliances exceeding the AC outlet limit, connect to the Hard Terminals Blocks. Ensure the inverter's ground terminal is connected to the appliance's ground terminal.

Use Safety

• Do not operate the inverter under the influence of alcohol or drugs. Consult prescription warnings regarding potential impairment of judgment or reflexes. If in doubt, do not operate.
• Individuals with pacemakers should consult their physician before using this product. Electromagnetic fields near a pacemaker may cause interference or failure.
• Avoid unintentional starting. Ensure the switch is in the OFF position when not in use and before plugging in any appliance.
• The power inverter outputs AC power equivalent to utility power. Treat its AC outlets with the same care as household outlets. Do not insert anything other than the appliance into the output terminals, as this may cause electric shock or fire.
