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.
