So I bought this for my recently purchased 2011 Apache 634. It was a rushed purchase as needed something quickly for an off grid trip. I can't make head nor tail or the controller instructions so have not meddled with any of the settings (aside from fitting an inline fuse) and all seemed well the first night with charge going to the leisure battery. In the morning the 12v tripped out and even though I could just switch it back on the sargent EC300 panel was showing the leisure battery charge fluctuating wildly between about 13v and a bit above 15v. This would trip out the 12v each time so I unplugged the solar panel. Is this likely a case of needing to get someone out who can understand the Dokio controller and tweak the settings or more case of chucking that in the bin and buying a better quality controller? https://www.ebay.co.uk/itm/26620447...pid=5339023013&customid=&toolid=10001&mkevt=1
