3 Application Scenarios and Settings
The LUNA2000 battery is mainly used in grid-tied systems of residential rooftop PV plants.
The system can be classified into the following three types based on application scenarios:

Grid-tied energy storage system (ESS)

Grid-tied and off-grid ESS

Off-grid ESS
Multiple working modes can be set, such as maximum self-consumption, time-of-use, and
fully fed to the grid.
3.1 Grid-tied ESS
3.2 Grid-tied and Off-grid ESS
3.3 Pure Off-grid ESS
3.1 Grid-tied ESS
3.1.1 Grid-tied ESS Networking
Networking 1: Inverter + Batteries
The grid-tied ESS consists of the PV strings, LUNA2000 batteries, inverter, AC switch, load,
power distribution unit (PDU), and grid.
The SUN2000-(2KTL–6KTL)-L1 or SUN2000-(3KTL–10KTL)-M1 inverters are supported.
The PV string converts solar energy into electric energy, which is then converted by the
inverter into power for loads and then fed to the power grid.
