100 watt solar with deep cycle flooded batteries?

I have a 2019 26’ Flying Cloud RBT. I bought a 100 watt solar panel that I have rigged to plug into the zamp plug on my camper. The batteries are deep cycle flooded I think (Interstate). I wonder if the are OK to charge with solar and in what mode (normal, float, etc.) should I set the solar controller? Thanks for any good advice!

The Zamp plug connector is likely wired opposite of your aftermarket panel as I have read. For some stupid reason, Zamp wires the plug where hot is ground and ground is hot. Check with a continuity tester. Easy to reverse leads.

Also, did your panel come with a MPPT controller? If not, you’ll need one. wire panel to controller, then controller to Zamp plug/ battery.

Your batteries are fine, just make sure you check cell levels and keep them at the right place. Most portable panels that size come with a built in controller that will do it right. If not, the controller should be multi-stage that automatically changes the charge profile, you should only have to position a switch for the type of battery.

I read that the “float mode” voltage is default set to 13.8 volts. I can adjust if needed. Is that correct for deep cycle batteries?

Almost all solar chargers are setup by default for flooded lead acid.

Charging mode for normal/float etc. is automatically managed by the charge controller depending on the state of charge of your batteries as detected by voltage level.

Nothing more to do or configure in your case other than to plug it in with the right polarity.
