4.6.3 DC connection
The MT series inverters are quipped with 2 (SolarMax 8MT2 /10MT2 / 13MT2 / 15MT2)
and/or 3 (SolarMax 13MT3 / 15MT3) MPP trackers. Each tracker has two plus and minus
poles for the connection of two strings per tracker input. One string can be connected to
tracker 2 of SM8MT2.

Minus connections
The position of the plus and minus connections is identical for all DC inputs (1 to 3).
Trackers 1 to 3 operate independently of each other, thus enabling simultaneous con-
nection of strings with different characteristics (orientation, dimensioning, module type)
to a shared inverter. The plus and minus connections of different trackers must not be
connected to each other:

The plus and minus feed lines for trackers 1 to 3 must be run to the inverter separately
from each other:
