The turbine should be connected to an MPPT regulator to obtain optimum efficiency.
All brands of MPPT regulators are suitable, provided the open-circuit input voltage is 250 V.
Example: SRNE MC4860N25 MPPT regulator.

Charge diversion :

– The batteries are protected from overcharging by the TS45 charge diversion controller, which is connected to diversion resistors and produces heat.
See schematic diagram.
The production of domestic hot water is possible with a suitable resistor and a contactor to switch to the resistors when the hot water tank is full: contact me.
NB: like wind turbines, all hydroelectric turbine assemblies connected to a battery bank require a load diversion controller because the turbine runs 24 hours a day.

– You can also connect the turbine directly to a mains inverter (without a battery bank), see diagram. The condition is that it must be connected to the grid.
The grid inverter must also allow an open circuit input voltage of 250V.
In this case, the grid acts as the battery-controller-resistors system. It absorbs the turbine’s surplus production and provides the additional power for your consumption.
Example of inverter: Growatt 1.5kW – MIC 1500TL-X. Virtual storage solution to use surplus energy from the turbine: Urban Solar.

Installation recommendation :

A primary shut-off valve on the main pipe.
A pressure gauge placed before the secondary shut-off valve. The latter is supplied.
The turbine must be placed at least 50cm from the ground to allow water to drain off. Weight of the turbine: 22kg.
The turbine is designed for outdoor use: no need for additional shelter.
If your flow rate does not allow to use a nozzle larger than 12mm, it is preferable to use a single nozzle.
The cable used to carry the current must be 16mm2 or 10mm2 in cross-section, depending on the distance and power.
Can be coupled to a solar and/or wind power installation.
Contact me for advice on buying a cable.
The use of an adjustable nozzle must be conditioned by good filtration on the collector, otherwise small grains of sand will regularly get stuck and premature wear will occur.

Maintenance :

Clean the air filters once or twice a year (dismantle without tools, wash with clean water).
Pelton wheel blades: loss of efficiency after 3 years if coarse filtering, over 5 years if fine filtering.
Maintenance-free bearings and spinnaker seals: minimum service life 4 years.
