It enables module-level shutdown and monitoring, and supportslong-string design.Functions and Features●Module-level MPPT: Implements maximum power point tracking of each PVmodule to improve the energy yield of the PV system.●Module-level shutdown: Adjusts the module output voltage to a safe rangewhen the output is disconnected or the inverter shuts down.●Module-level monitoring: Monitors the operating status of each PV module.●Long PV string supported: If all PV modules are configured with optimizers, aPV string can contain more PV modules than conventional PV strings. ModelThis document involves the following product models:●SUN2000-600W-P (Long input cable / Short input cable)●SUN2000-450W-P●SUN2000-450W-P2Figure 2-1 Model description (The SUN2000-600W-P optimizer is used as anexample)2.2 StructureOptimizer PortsFigure 2-2 Ports(1) Output port (positive)(2) Output port (negative)(3) Input port (negative)(4) Input port (positive)Optimizer DimensionsFigure 2-3 SUN2000-600W-P (short input cable)/SUN2000-450W-P2 dimensionsFigure 2-4 SUN2000-600W-P (long input cable) dimensionsFigure 2-5 SUN2000-450W-P dimensions2.3 Application ScenariosNO T ESelect PV modules with appropriate cable length to ensure that the optimizer can connectto PV modules.Optimizers configured for all PV modulesAll PV modules are connected to optimizers.In this scenario, the MPPT function, module-level shutdown and monitoring, andlong-string design are supported.Figure 2-6 Optimizers configured for all PV modules2.4 Configuration PrinciplesThe optimizer models supported by different inverters may vary, and differentoptimizers may be configured for the same inverter. Select the optimizer model asrequired.Configuration PrinciplesThe number of optimizers supported in a PV string, the upper limit of the stringpower, and requirements for connecting PV strings in parallel vary according to theinverter model. The configuration principles for different inverter models are asfollows:NO T EIf two strings are connected in parallel to the inverter under the same MPPT circuit, therestrictions for configuring optimizers are as follows:●The PV strings connecting to the same MPPT should contain the same number andmodel 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.Table 2-1 SUN2000-600W-P/SUN2000-450W-P2 configuration principlesTable 2-2 SUN2000-450W-P configuration principlesOptimizers supported by InvertersThe optimizer models supported by different inverters may vary, as described inthe following table.NO T E"√" indicates supported.
