I want to add on my Caravan a Solar Panel. Actual is build in a Blue Smart IP65 Charger that charges a 50Ah AGM Batterie. For charging with solar i bought a BlueSolar MPPT 75/15 Charger.
My Question, can i connect the MPPT Charger parallel with the Shore power Charger direct on the Batterie?
Providing both are configured the same (voltages) yes they can..
Just ensure you don’t exceed the charging current when both are running..
Thanks for your answer Misullivan,
may you could explain me what you mean with that: "Just ensure you don’t exceed the charging current when both are running." How can i make this ensure?
Yes you can no problem, but if you use both at the same time (also possible and fine) they won't be in perfect sync.
How can we be sure the MPPT or the charger see the correct battery voltage? I have a similar setup and the MPPT gets woefully confused thinking the battery is ready for absorption or float mode, it appears to be seeing the voltage from the Blue Smart charger.
