Moved over from Lead Acid deep cycle to the Lithium battery on my boat. Ensured the Li option on the Renogy Wanderer 10a controller was selected. Noted fluctuations in the PV voltage between around 14v to 16 v in full sun. After a few days in very hot weather, the controller stopped “seeing” the solar panel. Multimeter showed 20v reaching the controller, but no PV display came up on the controller screen. Battery still full (13.4v). Is the controller fried, or can it simply be reset? What should I do?
