PowerSpout ME
There are several versions MPPT Enabled versions of the PowerSpout.
PowerSpout ME100
(Cable length 50 - 750)
Designed for MPPT regulators that have a 100 VDC limit or for the Latronic grid-tied inverters that are made in Australia.
PowerSpout ME120
(Cable length 50 - 1000)
Connected to a battery bank through a MPPT controller such as the Outback FM60. Used in markets that have the 120 VDC ELV laws.
PowerSpout ME 140
(Cable length 50 - 1500)
Connected to a battery bank through a MPPT controller such as the Outback FM60. Operates at close to the 150 VDC limit of common MPPT regulators
PowerSpout ME 250
(Cable length 50 - 2000)
Connected to a battery bank through a MPPT controller such as the Midnite Classic 250. Operates at close to the 250 VDC limit of this MPPT regulator.
These products are similar to the GE version but generats a DC voltage up to 250 vdc, to save on cable costs. At the end of the cable an MPPT (maximum power point tracker) controller coverts the incoming voltage to that required to charge the batteries. The main advantage of MPPT is that the turbine will set itself up to the correct speed to extract maximum power from the flow without the need for manual adjustment. When the batteries are full the MPPT controller can then turn on a hot water element to divert energy not needed.
Inside the hydro turbine is a fast acting electronic circuit which progressively connects a water element to prevent the voltage rising rapidly. This prevents the turbine from damaging standard MPPT controllers that typically have an upper limit of 140-150 vdc input.
