Solar Installation – Flying High and Far Away

I have been posting about this issue off and on since my old-tech ASC Shunt controller I got in 2011 mentions it in its manual.

I have had other controllers since (my fault frying two :( ) and they don't make it so clear in their manuals as the ASC does. Only about the 12/24 on first powering up so the controller can know what battery voltage to go with.

So those fancy MorningStar guys have caught up with the old-time Specialty Concept guys? :)

Good information. Thanks. Always good to be informed and act accordingly.

Please clarify if I have this concept backwards/mixed up/flat out wrong.

Typically instructions are to NOT power up you charge controller with amps coming downstream without battery bank already attached to Charge controller, first. So in sequence one should stop/switch off Solar Panels, then turn off battery bank/switch in that order?

Then solar panel instructions advises not to hook up when solar panel are under load (harvesting) to charge controller.(?) So am I to interpret that as; you should black out (cover/night time mode) all panels on that line before putting them back on line to the charger, after battery is reattached (on line) to Charge Controller?

Thanks.
