3.5.4 Renewable Energy Supply

Note.

Before making connections, check the Data label to confirm power supply requirements.

An output regulator can be omitted if the off load-voltage is below V in max.

Renewable energy generators do not operate at maximum capacity, for example, low wind
speeds, coating of the solar panel with dust and wildlife droppings and short daylight periods in
winter. For these reasons, in some installations, generators with a capacity greater then the
specified 5 W minimum should be used. Contact ABB for a technical note, giving guidance on the
selection of suitably sized generators for AquaMaster3.
Renewable energy supply requirements:

Input12 V (nominal)

V in max.22 V DC

V in min.6 V DC

Solar panel or wind generator 5 W or greater
