Batteries are increasingly becoming the centre of independent power systems, whether it’s for vessels, vehicles or remote land based locations. Batteries are used in hybrid systems in cars and vessels, in combined fossil and renewable systems combining for example wind and solar power sources or for emergency backup systems. Batteries are the key to a better energy balance in any system, a key to lower operational costs and reduction of emissions.

In a WhisperPower system the battery has a central role: it is the energy tank, dictating when power sources (battery charging devices) should start to refill “the tank”. The selection of the right battery capacity and technology determines the functionality and durability of such systems. WhisperPower has built up our expertise in this field as a supplier of premium batteries over the past 20 years and would like to share its knowledge with our customers.
