Do I need any experience in electricity to install a solar water heater?
No, you do not. In fact, if you purchase a pre-packaged kit from Sunmaxx, the pump station (which is has the controller and pump built in) simply has a 3-prong plug that you insert right into a 110v wall outlet. The only thing that you would need to do is to insert the sensor wire into the appropriate location on the controller. Luckily the sensor wire is non-polar so you can’t mess it up (knock on wood).
