Too much solar?

Yes system is all DIY, controller is a Pic cpu setup of my own design, whole system runs off 12 vdc, charged from small pv panel.
Actually two independent setups, one built first was a prototype and at ground level (2 sqm) so it was easy to get to, has wooden case. Second system roof mounted has alloy cases with welded seams (8 sqm), both use 1mm thick polycarbonate for glazing, been up for 4 years now with no problems.
Location is Wellington NZ, not the best weather approx 2000 sunshine hours PA, very windy often part cloudy

Intend to install 3.6KW PV on ground mounted posts, soon as I can purchase grid tie inverter.

Will link to a couple of images, one shows prototype panel that now feeds a HWC supplying just the kitchen (180L), other mounted on the roof connects to the main HWC (300L). I have some other photo's showing the heat dump etc but they are not online so not sure how to post them.

Sorry system doesnt allow me to post any links to images. So what do I do ?

Cheers
Mike
