Pure Sine Wave
Inverters output a pure sine wave similar to the waveform of the grid power. In a pure sine wave, the voltage rises and falls in a smooth fashion with very low harmonic distortion and cleaner utility-like power.

This gives users stable enough power to operate tools, fans, lights, computers, and other electronics without any interference. Pure sine wave inverters are in many cases more efficient, allowing users to use less energy and allow for more device capability. The main advantage to pure sine wave inverters is that they are used to operate sensitive electronic devices that require a high quality waveform with little harmonic distortion. Almost any electronic device could be powered using a pure sine wave inverter.

Technical specifications

PANEL DESCRIPTION

Installation

• WARNING Make sure inverter is in the off position before connecting anything.
• CAUTION Do not over-torque or over tighten the terminals. This could potentially damage the unit.
• CAUTION Refer to the technical specifications for max wire sizes on the controller and for the maximum amperage going through wires.

Location Recommendations

WARNING
Never install the inverter in a sealed enclosure with flooded batteries. Gas can accumulate and there is a risk of explosion.

Ensure installation follows the following guidelines:

1. Cool, dry, well-ventilated area — Heat is the worst enemy for electronic equipment.
   Inverters must be in an area where the fans are not blocked or where they are not hit directly by the sun. They should be in an area free of any kind of moisture and allow for clearance of at least 10″ around the unit to provide for adequate ventilation.

2. Protection against fire hazard — the unit should be away from any flammable material, liquids, or any other combustible material. The unit can spark and the consequences could be severe.

3. Close proximity to battery bank -prevent excessive voltage drop by keeping the unit close to the battery bank and having a properly sized wire going from the battery bank to the inverter.

4. WARNING Do not install the inverter in the same compartment as the battery bank because it could serve as a potential fire hazard.

5. Limiting electromagnetic interference (EMI) — ensure the inverter is firmly grounded to a building, vehicle, or earth grounded. Keep the inverter away from EMI receptors such as TVs, radios, and other audio/visual electronics to prevent damage/interference to the equipment.

6. Secure inverter —the inverter could be stand alone or mounted using the outlying terminals on the inverter.

WARNING
The inverter should never be mounted vertically ona vertical surface since it would present a hazard for the fan opening which is crucial for cooling the inverter.

Sizing a Battery Bank

• Determine the amount of Watts (Amps * Volts) for the load, and how long the load needs to operate-each electrical appliance has technical specificationsindicating the watts, or the volts and amps required for operation.
• Estimate load run-time—Battery size depends on load watts and run-time. Most loads are not constant, so estimation is very important.
• Determine Amps aSat ormany hours – Amp-hour (An)

For this inverter, the battery bank will be 12 volts direct current (12 VDC)

• NOTE This is just an example. Actual quantities vary by battery capacity and rates of discharge.
• NOTE To power the microwave in the example, the user must use an inverter that is at least 1000 watts, if not more.
• NOTE Tip: Users are recommended to use ≥200Ah battery to connect the inverter.

DC Side Connection

• WARNING Pure Sine Wave Inverters are suitable for 12V 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 Damage to the inverters due to reverse polarity is NOT covered by warranty.

Operation

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

AC Side Operation

1. Connect electronic devices to electrical socket (s) on inverter. Flip inverter power to ON position (on AC side)
2. When finished, switch AC devices off FIRST, then turn off inverter switch

• CAUTION Avoid switching on the inverter with the load (electronic devices) already switched on. This may trigger an o verload since some electronic devices have an initial high power surge to start.
• CAUTION 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.

Recommended Ground-Fault Circuit Interrupter (GFCI)

• A ground-fault circuit interrupter, or GFCI, is a device that help protect people from electric shocks by de-energizing a circuit or portion of a circuit within an established period of time when a current to ground exceeds some predetermined value that is less than that required to operate the overcurrent device (circuit breaker or fuse) of the supply circuit. GF CIs are usually required in wet or damp locations.
• While the inverter is equipped with a GFCI, it is recommended to install an external GFCI where you can manually test the circuit.
• The following table lists GFCIs that meet the specifications and will function properly when they are connected to the AC Outlets of the inverter.

• WARNING Risk of electrical shock. Use only ground-fault circuit inter rupters [receptacle (s) or circuit breaker(s)] compatible with your P2 inverter.
• WARNING Risk of electric shock. Use only class A ground-fault circuit-interrupter [receptacle (s) or circuit breaker(s)]. Other types may fail to operate properly when connected to this unit.
• CAUTION GFCIs shall be installed in a recreational vehicle’s wiring system to protect all branch circuits.
