I&#39;ve tried doing this using voltage on/voltage off rules for the Load relay, and it works sortof, but I&#39;m not finding a perfect voltage range to make it work (the house battery is LFP, the starting battery is Lead Acid). Anyone get this to work? </p></div> Wed, 28 Apr 2021 21:22:31 GMT xmd Answer by adev <div class="fr-view clearfix"><p>I would think you could make this work by connecting your fan to the load outputs, and setting the load disconnect to say 13.2v or so (depending on battery charge settings). That should allow the load to come on whenever there is float charge voltage or higher present, and shut it off at night.</p> </div> Mon, 03 Jun 2019 11:44:00 GMT adev Answer by Paul B <div class="fr-view clearfix"><p>Maybe just connect it to the PV output and let the fan run when the sun shines.</p><p>it will need to be able to run at the MAX pv voltage without damage so pick the correct voltage.</p><p>I suspect that as the voltage reduces the fan will just slow down.</p> </div> Thu, 16 May 2019 05:25:56 GMT Paul B
