I'm planning a solar installation with Panels setup in series to make 48v. I see that I would need the MPPT 150/30 Charge Controller. However, the documentation for the controller referred to equalizing of batteries but I am assuming that this would only be for 2 x 12v batteries in series whereas I'm planning for 4 x 12v = 48v.
Documentation for the Battery Balancer unit confirms that 3 x Balancer units are needed for 48v.
Therefore, if I want battery equalization, am I correct in saying that i would not need Balancer units if I went with 24v but at 48v I'll still need 3 x units ?
However, if I went with 24v and had 2 sets of 12v battery pairs in parallel, can the Charge Controller equalize batteries in Parallel ?
