How do I connect the charge controller to the battery?

You will need a negative and positive cable to connect the charge controller to the battery. The cable size is determined by the size of the charge controller. We recommend using high quality, certified cable with high quality lugs and shrink tubing. Our cables are UL listed and extra flexible and made for inverter applications. Here is a guide for sizing your cable. Note this is recommended for the AIMS Power cable. The AIMS cables have high quality copper and braided differently, which have higher current ratings. NOT all cable is made the same.

80 & 100 amp charge controllers: 6 AWG

60 amp charge controller: 8 AWG

40 amp charge controller: 10 AWG

30 amp charge controller: 12 AWG

10 amp charge controller: 16 AWG

AIMS Power does not offer 12 or 16 AWG cable. You can always use 10 AWG as a substitute. It’s ok to go with bigger wire.

    Bigger wire does not easily connect to a controller. What can I do?
