The WhisperPower WP-Combi is a cost-effective, powerful pure sine wave inverter, a 3 stage battery charger and a robust high speed AC to AC transfer switch. The WhisperPower WP-Combi features a distortion free sine wave inverter, with no limitations in use: from standard household appliances up to sensitive electronics, the sine wave inverter operates the connected load.

The sophisticated battery charger in the WhisperPower WP-Combi complies with today's requirements. The power factor corrected battery charging gets the most out of your shore power, three stage charging algorithm for a quick and complete charging process. Suitable for any battery: AGM, GEL and open lead acid (adjustment via dip switches). Temperature compensation for a safe charging process.

The WP-Combi also has seamless transfer (UPS mode) in the event of an incoming grid failure, or a sudden generator stop, the appliances connected to the WP-Combi output will switch to the inverter automatically which will take over the power supply to the load. The transfer time is ultra fast to prevent any damage (approximately 10ms).

The WhisperPower WP-Combi is supplied complete with a remote control panel and 6 metre cable which allows the inverter to be switched to on, to off or to charger only mode. A RS485 communication port is available for further external communication if required. Power sharing adjustment is also included by setting the charge current on the front of the WP-Combi inverter / battery charger unit. WhisperPower WP-Combi offers silent AC power, whenever you need it. With an integration battery charger recharges the battery without a generator.

  • What does an IP rating mean? +

    The IP rating of a product is a unit of scale used to classify solid particle and liquid ingress protection, by using a two number system. The meaning of each number is listed in the below table:

    First Digit
    Number Protection
    0 No protection against contact and ingress of objects
    1 Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
    2 Fingers or similar objects
    3 Tools, thick wires, etc.
    4 Most wires, screws, etc.
    5 Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact (dust proof)
    6 No ingress of dust; complete protection against contact (dust tight)


    Second Digit
    Number Protection
    0 No protection
    1 Dripping water (vertically falling drops) shall have no harmful effect.
    2 Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position
    3 Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.
    4 Water splashing against the enclosure from any direction shall have no harmful effect.
    5 Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.
    6 Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.
    6K Water projected in powerful jets (6.3mm nozzle) against the enclosure from any direction, under elevated pressure, shall have no harmful effects.
    7 Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1m of submersion).
    8 The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.
    9K Protected against close-range high pressure, high temperature spray downs.
