PowerSpout turbines are micro-hydro generators that convert the potential energy of a watercourse to electricity.

PowerSpout turbines are micro-hydro generators that convert the potential energy of a watercourse to electricity. This is achieved by using water to spin the rotor and hence the generator, which generates electricity (3-Phase AC power) internally that is then rectified to DC.
The PowerSpout range includes turbines which can operate in particular situations, primarily dictated by water flow rate then available head (vertical fall height).

2. PowerSpout turbine options
PowerSpout PLT and TRG turbines are also identified by voltage to suit the site and system design e.g. connected directly to battery banks, connected to battery-based MPPT regulators or to grid-connect inverters. The turbine abbreviation (PLT, TRG) is followed by a number that indicates the approximate maximum power point voltage (MPPV), which is also the operating cable voltage.

For example:
 PowerSpout PLT 28 has an MPPV of 28 V (connects to 24V battery bank via PWM regulator). 28 V is the bulk voltage for a 24 vdc battery.

 PowerSpout PLT 200 has an MPPV of 200 V (connect to grid via grid-tied inverter)
For PowerSpout LH turbines, for example the LH200, the 200 is not the MPPV but the maximum open circuit voltage (OCV) at turbine runaway. This is because there are no LH turbines that connect directly to batteries. All LH turbines require MPPT regulation for battery charging or the use of a grid connect inverter.

The relationship between OCV and MPPV is stated below:
 PLT and TRG turbines OCV is approximately 3 x MPPV
 LH turbines OCV is approximately 2 x MPPV

2.3. PowerSpout LH Common PowerSpout LH and LH Pro products

All LH and LH Pro products connect via MPPT regulators or grid-tied inverters. There are no direct battery options available.

 LH150 and LH150Pro – use with MPPT regulator rated for up to 150 VDC charging 12/24 VDC batteries. Cable voltage may be as low as 50 VDC.
 LH250 and LH250Pro – use with MPPT regulator rated for up to 250 VDC charging 12/24/48 VDC batteries. Cable voltage may be as low as 80 VDC.
 LH400 and LH400Pro – use with MPPT regulator or grid connect inverter rated for up to 400 VDC. Cable voltage may be as low as 140 VDC.
