WhisperPower introduces hybrid power system for remote applications

JB Drachten, Netherlands (ots) - WhisperPower in the Netherlands
has developed a new decentralised power system to provide mains
electricity to locations without a (permanent) grid connection. The
GRID INDEPENDER has been launched at the Intersolar trade fair last
week. It is able to deliver 230 VAC/ 50 Hz, 7 kW from the internal
maintenance-free gel battery via a true sine wave inverter, and can
be run in parallel with the WhisperPower diesel generator. This
innovative mini-grid will be available in the autumn for around EUR
9,900 excluding solar panels. In nominal conditions the diesel
generator will not be running. When the battery is discharged below a
certain level, or the load demand exceeds the power which the
inverter can deliver, the built-in variable speed diesel generator of
3.8 kW will recharge the battery pack within a short period. The
start and stop process is fully automatic, with the sine wave
inverter of 3.5 kW continuous power rating always on stand by to feed
the AC appliances.

The system is prepared to plug in up to 2 kW of solar power (24
VDC, 48 VDC), saving diesel fuel costs and generator operating hours
in case of sufficient radiation. The system is fitted with an AC
input for when a utility grid is (temporarily) available. The AC line
will be used to recharge the battery or feed the connected AC
appliances in a direct way. In case of a power cut or fluctuation,
the inverter will back up the AC load to ensure no interruption.

Applications for the GRID INDEPENDER are remote holiday houses,
grid-replacement systems for permanent residences, traffic systems,
security systems, emergency power/back up systems, and as a primary
source of power for companies and accommodations in areas where the
electricity grid is poor or non-existent.

Grid Independer

Brief specifications:

- Cabinet 150 x 50 x 58 cm (lxhxd) - Ready to use in any commercial
or recreational location.
- 230 V/50 Hz GENVERTER diesel generator operating between 2400 and
3600 rpm (load dependent).
- 30-litre diesel fuel tank.
- Built-in sine wave inverter of 3.5 kW power rating to supply high
quality sine wave power.
- Automatic 3 stage battery charger for recharging the battery during
engine running time.
- Automatic switching to main utility when available.
- Built-in transfer system: automatic, seamless load management from
utility power (when available) to inverter/generator.
- 220 Ah 24 V high quality GEL batteries.
- Automatic "silent mode?: engine switches off at low AC power
demand; sine wave inverter takes over AC power provision, utilising
the 24/48 VDC battery, connected to the system.
- MPPT Charge Controller to connect the solar array to the battery in
the most efficient way.
- Extended remote control/system monitoring interface for all vital
AC and DC functions.
