I just purchased Elite 200 V2, Charger1 and a solar panel. Looks like Elite 200 has just one DC input port and I read that using MC4 Y-branch parallel connectors is not feasible/recommended.
Is there a way to permanently connect those 3 pieces together?
Do I have to manually plug and unplug my charging sources?
Answer to your 1st Q is NO - 2nd Q is YES. It’s one or the other as they operate at differing votages.
You need Charger 2 for that function.
