Tempest Battery Level & Recharging

I received my Tempest on June 17th. When I installed it, the voltage started at ~2.50 and has dropped consistently since then bottoming out between 2.39 and 2.40. When will the solar panels kick in and start charging the battery? It’s been stuck at 2.40 for the past 18 hours with plenty of directly sunlight.
