manual are for guidance only.
Device Model Description
• When only one inverter is used in the system, it is supported to connect
generator.
• When multiple inverters are used in the system, it is not supported to connect
generator; a maximum of 16 inverters are supported to form a parallel system,
and the Ezlink3000 is required in the parallel system.
GW8000-ES-C10 • The complexity of the parallel system increases with the increase of the number
Inverter GW10K-ES-C10 of inverters in parallel. When the number of inverters in parallel system is ≥ 6,
GW12K-ES-C10 please contact the after-sales service to confirm the installation and application
environment of the inverters to ensure stable operation of the system.
Requirements for parallel system:
• The software version of all inverters in the system is the same.
• The ARM software version of the inverter is 08 (415) and above.
• The DSP software version of the inverter is 00(2525) and above.

Description
Battery of different models cannot be mix used.
• LX A5.0-10: The nominal charging and discharging current of a single battery is
60A; a maximum of 15 batteries can be connected in parallel in one system.
• LX A5.0-30: The nominal charging current of a single battery is 60A, and the
discharging current is 100A; the maximum continuous charging current is
90A; the maximum continuous discharging current is 150A. A maximum of 30
batteries can be connected in parallel in one system.
• LX U5.4-20: The maximum discharge current of a single battery is 50A; A
maximum of 6 batteries can be connected in parallel in one system.
• LX U5.0-30: The nominal charging current of a single battery is 60A, and the dis-
charging current is 100A; the maximum continuous charging current is 90A; the
maximum continuous discharging current is 100A. A maximum of 30 batteries
can be connected in parallel in one system.
• Supports connection to lead-acid batteries of AGM, GEL, and Flooded types.
• The number of batteries that can be connected in series is calculated based on
the voltage of lead-acid batteries, and the total voltage of batteries connected in
series is not allowed to exceed 60V.
• When the charging and discharging current between battery and inverter is less
than 160A, it supports direct connection between battery and inverter without
using a busbar. For example: It supports connecting GW8000-ES-C10 to LX A5.0-
30 without using a busbar. For detailed battery wiring methods, please refer to
6.6 Connecting the Battery Cable.
• When the charging and discharging current between battery and inverter is
≥160A, a busbar or busbar box must be used to connect the inverter. (Current ≥
M x IBat rated. (M: The quantity of batteries connected in parallel in the system,
IBat rated: The rated current of the battery).
