Solar Power set-up

Hi, @zie_e
Welcome to the forum.
https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum

We need more information, like what are the power requirements of the pumps.

A full schematic of your envisioned project would be welcome.

Can you please tell us your electronics, programming, arduino, hardware experience?

Thanks.. Tom.... :smiley: :+1: :coffee: :australia:
