 When charging there is a near-constant gurgling sound. This is relatively normal but the constancy could point to the batteries nearing their end of life.
+====== Charge Controllers ======
+The solar panels provide varying voltage/current depending on the amount of sun they are getting. Because of this, you can't just wire them directly to the batteries, you need a controller that ensures that they are connected to the batteries when they have sufficient voltage to charge the batteries.
+Because there are two arrays of solar panels, Ken made the good decision to use two separate charger controllers. Each one is a [[10-001-1_REV_U_Classic_Manual_19Jan2022.pdf|MidNite Classic]] (I am pretty sure, that they are Classic 250. I am unsure if they are the SL (solar only) or the 'normal' ones.
+From the MidNite Classic documentation:
+<blockquote>Trusting a State of Charge (SOC) meter, which can lose calibration over time and give you
+false readings. You need to verify specific gravity and or verify the charge voltage is being
+met. Never fully rely on the SOC %; it is just a good, quick referenc</blockquote>

+====== DC Dicsconnect ======
+The MidNite controllers and the battery bank are connect to a [[dcdisconnectuserguide-42813.pdf|Trace Engineering DC Disconnect]].
