Solar Installation – Flying High and Far Away

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?

No need to black out, just follow the above posted sequence IF you have a switch (DC rated bestf) for the panels.

There is also advice to NOT use MC4 or related connectors to connect/disconect panels. DC is much more likely to arc across the connections because unlike AC the voltage does not cycle through 0V.
