Connecting Solar Panels
A. Sol-Ark has DUAL MPPTs for two separate PV input pairs
B. MAX PV input = 13kW (± 5%) / system | 6.5kW / MPPT | MAX 500V
OC
PV | MAX I
SC
/MPPT 25A (limiting to 20A)
Damage will occur if PV V
OC
> 550V
C. Parallel strings per MPPT must be the same Voltage
i. PV1 A/B must be the same voltage if using both strings
ii. Panels on the same MPPT CAN face different directions
D. Ground the panel MOUNTS/FRAMES to any ground in the Home via 12AWG wire
E. IF using Y-Connectors: Running two strings in parallel, totaling 20A (self-limiting)
F. Connect the solar panel strings as indicated by the following diagrams:
