2.4 Configuration Principles

The optimizer models supported by different inverters may vary, and different
optimizers may be configured for the same inverter. Select the optimizer model as
required.
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:

NO TE
If two strings are connected in parallel to the inverter under the same MPPT circuit, the
restrictions for configuring optimizers are as follows:
● The PV strings connecting to the same MPPT should contain the same number and
model of PV modules and optimizers.
● All PV modules in the two strings must have the same orientation and tilt angle.
You are advised to use long strings instead of Y-shaped terminals.
