In most of my readings about connecting and disconnecting stand alone/permanently mounted solar panels, charge controller, and batteries it always mentions connecting your charge controller to the batteries first followed by the solar panels to the charge controller in order to protect your charge controller and panels.
With the Eclipse solar suitcase with attached Adventurer charge controller you seem to just either disconnect the alligator clips from your battery or unplug it from the rv side port sae connector. Is that right?? If so, why isn't the charge controller and panel at risk by not disconnecting and connecting in the same order as recommended for the stand alone/permanently mounted solar equipment??
I believe the real reason is PWM may not require it. MPPT certainly does.
Generally one connects the controller first, this allows the controller to get power and determine if it is a 12v or 24v system. See the link above for what admin said at that time, might call em and ask!
If I had a suitcase I would likely turn it away from the sun, plug in or connect clips, then turn the panel to the sun.
I guess because my panels are connected to the suitcase controller via mc4 connectors to mc4 adapter lines I could unplug the two pv input line mc4 connectors from the adapter line mc4 connectors without too much effort just to play it safe.
