How To Connect 4 12v Batteries To Make 48v

48v DC Solar Bombardment Wiring Diagrams

Below are suggested wiring topologies for connecting batteries in serial to produce a 48v power supply for the solar air conditioner. Annotation that the batteries, besides as the solar panels, should be continued to the charge controller. The DC air conditioner ever connects to the batteries. See likewise solar battery options.

If the bombardment lists a CCA rating it is probably not a true deep cycle battery. Note that 4 10 12v batteries are wired in a series to accomplish 48v, there can be 2 or more 48v series of 4, wired in parallel to each other.

Click paradigm to overstate	Click image to enlarge	6v batteries are typically golf game cart batteries, which are excellent for solar or DC powered air conditioner applications. Notation that golf cart batteries also may come in 8v which can likewise be used in a 48v air conditioner system, in that example you would use 6 or 12 (or whatsoever multiple of 6) of them wired in serial/parallel similar to the way 6v batteries are wired.
