On a 12v 860Watt PV panel system do the panels need grounding to earth? The charger/inverter is charged by the mains. The panels supply some 12v power for the batteries. The inverter only supplies 240v to a non-mains circuit. No panel earth point indicated on the inverter charger. The inverter/charger relays the, mains/battery power supply earth, depending on the supply. I have an earthing rod ready...

Guys A bit of a post as a "heads up". I was fitting my replacement controllers today (both my Sunamps are being replaced, a story for another day) and nearly forgot to do something pretty fundamentally important. The reason for this post is that I could easily see a busy plumber/sparky/installer completing missing this. Let me explain firstly with some pictures. Here's the controller as supplied by Sunamp: For simplicity I've removed the lid and the earthing fly lead which is screwed to the back panel (you can see the screw just below the contactor bottom right). Then here's the wiring diagram which is on the back of the lid and also printed in the manual: So as per the title the thing we need to be focusing on is earthing. You will note that the diagram shows the earthing connection across the three live blocks and then back (assumably to the case?) BUT and it's a BIG but. Look again at the controller image the earth wiring is NOT there. Nowhere in the manual does it tell you that its your responsibility to make these connections for the earthing. As far as I can see if you were to fail to make these connections the Sunamp unit itself and the controller case would not be earthed.

Hi All there has been a useful conversation over the merits of plastic pipe (HEP2O, Speedfit etc) in the following thread: Linky which triggered another question in my mind: What are the requirements for earth bonding where an install is primarily plastic? When and where should it be used?
