Re: Charge Controller - Load Connection
In my opinion, allowing battery voltage to drop below 12 volts, other than for relatively brief periods while under heavy loads, will be draining the battery below a safe level for good battery life. That's the way I run my system and my batteries are still in excellent condition after 10 years. But I guess it all depends on how one wants to treat their batteries and how ready they are to replace those batteries on a more or less regular bases.
