http://www.peplers.blogspot.co.uk/2013/07/off-grid-solar-pv-upgrade.html From opening the box to turning it on, the process I went through to install the charge controller. This is the Morningstar TS-MPPT-60, a 60 amp solar charge controller which includes maximum power point tracking. It can also operate at 12, 24 or 48V. This updated version of the video includes earthing (or grounding) as well. The battery sense wire isn't covered in this video, I'll add this at a later date.
It's currently connected to our off-grid PV system, which has 240W of solar panels. We're upgrading to 750W soon, which is why the new controller is needed. The old one was a Morningstar SunSaver MPPT, which did its job very well for a few years prior to this upgrade.
