When the SUN2000-(12K-25K)-MB0 series inverters are used in the SmartLogger3000
networking scenario, a maximum of three inverters can be cascaded, and each inverter can
connect to a maximum of four ESSs.
In the preceding scenario, the following version mapping requirements must be met:
● SUN2000-(12K-25K)-MB0 series: SUN2000MB V200R023C10SPC200 or later
● LUNA2000-(5-30)-S0: FusionSolarDG V100R002C00SPC127 or later
● SmartLogger3000: SmartLogger V300R023C10SPC310 or later
● FusionSolar SmartPVMS: SmartPVMS Plant V600R024C20CP0005 or later
● FusionSolar app: 6.24.00.350 or later
The grid-tied ESS supports a maximum of three SUN2000-(2KTL-6KTL)-L1 inverters (with
batteries) cascaded. In this scenario, the inverters can be connected to the grid only at the
same phase and controlled only by a single-phase power meter. Grid connection at dierent
phases or using a three-phase power meter is not supported.
Smart Dongle Networking
● The grid-tied ESS supports inverter cascading. A maximum of three inverters
can be cascaded. The batteries can be connected to one of the inverters for
management. The batteries, power meter, and Smart Dongle need to be
connected to the same inverter.
● When the battery working mode is set to Maximum self-consumption or
TOU (time-of-use), the Smart Dongle must be connected. If the working
mode is set to Fully fed to grid, the Smart Dongle is optional.
