Solar pumping maximiser kit - PCB only

This is the bare PCB for the 12 and 20 amp maximiser kit, a device (previously sold by the Alternative Technology Association) which allows you to drive pumps and other motor driven devices directly from a solar panel or panels, without the need for batteries.

When used with pumps, the maximiser can provide up to 40% more pumping per day.

Note: This device is not designed for use as a battery charger, and must only be used with solar panels and motors/pumps. The maximiser was originally designed for brushed motor pumps and success with brushless motor pumps varies as it can interfere with the brushless motor controller in the pump.

Note: The PCB allows you to build either the 12 or 24 volt version. Please download the instructions for further details. Please also note that no components are provided, this is a bare PCB only.
