Product Overview

Component	Model		Description
Inverter (master and slave)	SUN2000-(2KTL-6KTL) -L1 SUN2000-(8K, 10K)-LC0 SUN2000-(8K, 10K)-LC0-ZH		A maximum of three inverters can be cascaded. L1/LC0 inverters can be cascaded.
Energy storage system (ESS)	LUNA2000-(5-30)-S0 LUNA2000-(7, 14, 21)-S1		If there is only one ESS, it must be connected to the master inverter. Each inverter can connect to a maximum of two ESSs, each L1 can connect to a maximum of one ESS. The LUNA2000-(5-30)-S0 and LUNA2000-(7, 14, 21)-S1 cannot connect to the same inverter in a parallel system. If inverters are cascaded, the LUNA2000-(5-30)-S0 and LUNA2000-(7, 14, 21)-S1 cannot connect to different inverters.
Backup Box	Backup Box-B0		AC input voltage range: 198–253 V If there is only one Backup Box, it must be connected to the master inverter. The SUN2000-(8K, 10K)-LC0, SUN2000-(8K, 10K)-LC0-ZH cannot be connected to the Backup Box.
Smart Power Sensor	Single-Phase: DDSU666-H YDS70-C16 DDSU71 DDSU1079-CT	Three-Phase: DTSU666-H DTSU666-HW YDS60-80 DTSU71 DHSU1079-CT	The Smart Power Sensor must be connected to the master inverter. It connects to the inverter over RS485 for output power management and power limiting. Only L1 supports the three-phase smart power sensor.
Smart Dongle	SDongleA-03(4G) SDongleB-06(4G) SDongleA-05(WLAN-FE)		The Smart Dongle must be connected to the master inverter. It connects to the management system and performs power scheduling. The SDongleA-03 (4G) is compatible only with the SUN2000-(2KTL- 6KTL)-L1.
Optimizer	SUN2000-450W-P2 SUN2000-600W-P		For details about the optimizer supported by the inverter, see SUN2000 Smart PV Optimizer User Manual

Note:
In the Smart Dongle networking scenario, a maximum of three inverters and six ESSs can be connected.

Cable Connections (Single-Phase Inverter L1 + ESS S0 + Backup Box B0)

Danger
Before connecting cables, ensure that all switches are OFF. Otherwise, electric shocks may occur.

Note
Signal cables must be outdoor shielded twisted pair cables.

Note
The wiring sequence of the Backup Box must be consistent with that of the inverter AC terminals.

Note
Connect other cables to slave inverters by referring to the connection method for the master inverter.
