2.3 Configuration Principles

The SUN2000-(600W-P, 450W-P2) cannot be used together with the MERC-
(1300W, 1100W)-P.
Configuration Principles
The number of optimizers supported in a PV string, the upper limit of the string
power, and requirements for connecting PV strings in parallel vary according to the
inverter model. The configuration principles for different inverter models are as
follows:
Issue 05 (2023-03-31)
NO TE
● Optimizers are not supported in off-grid scenarios.
● For the MERC-(1300W, 1100W)-P optimizers, one MPPT of the inverter can connect to
only one PV string.
● The capacity difference between PV strings connected to the same inverter must be less
than or equal to 2 kW.
● Partial configuration is not allowed. All PV modules must be connected to optimizers.
Otherwise, serious consequences may occur, and the resulting device damage is not
covered by the warranty.
