Install MPPT Paralleling Jumpers (Optional)

Where the DC input current exceeds an MPPT rating of 13 A, jumpers can be used to allow a single MPPT to intake strings with a total DC input current of up to 26 A.

Note
If needed, 4 inch jumpers can be made from 10 AWG copper wire.

The following MPPTs can be paralleled using jumpers:

  • MPPT DC inputs 1 and 2 paralleled with both positive and negative
  • MPPT DC inputs 3 and 4 paralleled with both positive and negative

Install Jumpers

  1. Land string with 13+ A (IMP) on MPPT 2 (lower row).
  2. Install jumper from MPPT 1 to MPPT 2 (upper row).
  3. Land string with 13+ A (IMP) on MPPT 4 (lower row).
  4. Install jumper from MPPT 3 to MPPT 4 (upper row).
