2.4 Application Scenarios
● An optimizer is delivered with two types of input power cables: long (1300 mm) or short
(100 mm) cables. For PV modules with long cables, select optimizers with short cables;
for PV modules with short cables, select optimizers with long cables.
● To minimize electromagnetic interference, ensure that the distance between the positive
and negative cables of an optimizer is minimized.
● The SUN2000-(600W-P, 450W-P2) cannot be used together with the MERC-(1300W,
1100W)-P.
Full
conguration: All PV modules are connected to optimizers.
In this scenario, the MPPT function, module-level shutdown and monitoring, and
long-string design are supported.
