[QUOTE="condor22, post: 300382, member: 1932"] A loose connector, on the output, should only do one of two things, 1. reduce the available charge (in simple terms) or, 2. get hot, again in simple terms. It shouldn't increase the voltage especially to that extent as the output V max (for an AGM is 14.4v) A panels VOC is generally noted as Max but is variable depending on sun conditions. Yours noted at 21.6 and measured at 21.3 is ok (keep in mind that over time a solar panels output does reduce. Assuming you have this; [url]http://www.projecta.com.au/Products/DualBattery/DCSolarChargers.aspx#!prettyPhoto[/url] The max input is 32VDC so your panel should never get close. However, you haven't mentioned what panel or panels you have, or how connected. How old is the Projecta? If you can try someone else's panels on your Projecta, and their controller on your panel, that would be the easy way to isolate the problem. (panel/s or controller) If the controller is at fault, they are generally made such that it would cost as much to fix as replace. However, contact your supplier and find out if it's worth sending it for investigation or not. Before you spend any money, it would pay to try getting your kit checked, panels and charger. [/QUOTE]
