Digital Controller for Constant Hot Water

For over 6 years we have successfully sold an analog controller that allows customers with lead/acid batteries to heat water with surplus solar energy.  The original design works for most customers, but it does not allow users to configure it to their precise needs in terms of on/off voltages and water temperature.

We are therefore pleased to announce that we now have available a Mark 2 DIGITAL product that is fully user configurable.
