Description
GoodWe SEC3000C is a smart energy controller cabinet for commercial and industrial PV and storage plants: up to 60 inverters on RS485 or 10 on LAN, with EzLogger3000C, a GM330 meter and a 15-port Ethernet switch inside.
GoodWe SEC3000C Smart Energy Controller
Mixed parallel operation: C&I on-grid and C&I hybrid inverters run on one controller.
Fewer parts to source: The logger, GM330 meter and 15-port switch are built into the cabinet.
Open to third-party control: Modbus control for external systems.
Adaptable EMS modes: EMS modes for different applications.
Logger, meter and switch in one cabinet
The standard configuration lists EzLogger3000C × 1, GM330 × 1 and a 15-port Ethernet switch. The built-in GM330 reads the grid connection point for grid-tied power regulation, so no additional meter is needed.
RS485 or LAN, each with its own limit
Up to 60 inverters connect over RS485 and up to 10 over LAN. The manual allows up to 20 grid-tied inverters on one RS485 bus, so more than 20 need more than one bus; port A1/B1 is wired to the internal meter by default.
IP66 cabinet for wall, bracket or pole
The 450 × 400 × 242 mm cabinet weighs up to 16.9 kg, is rated IP66 and mounts on a wall, a bracket or a pole. It runs on a 100 ~ 240 V, 50/60 Hz supply at up to 25 W, from -30 to +60 °C.
Mixed fleets of C&I on-grid and hybrid inverters
SEC3000C connects GoodWe's C&I on-grid and C&I hybrid inverters in parallel and monitors the plant centrally with real-time data collection. The manual codes the C in the model name as industrial and commercial solar storage.

Project fit
Where this model fits.
Scenarios that show which projects the GoodWe SEC3000C Smart Energy Controller belongs in, and the limits behind our engineers' recommendation.
C&I plants with mixed on-grid and hybrid inverters
A commercial or industrial PV and storage plant runs GoodWe C&I on-grid and hybrid inverters in parallel and needs one point for monitoring and grid-tied power regulation.
SEC3000C brings the logger, a GM330 meter and a 15-port Ethernet switch in one IP66 cabinet. It connects up to 60 inverters on RS485 and up to 10 on LAN.
- Inverter count by link: RS485 up to 60, LAN up to 10
- RS485 buses: up to 20 grid-tied inverters per bus
- Grid-point metering: GM330 for 3L/N/PE 172 ~ 817 V or 3L/PE 100 ~ 472 V line voltage, CTs nA:5A (200 ≤ n ≤ 5000)
- Auxiliary supply: 100 ~ 240 V, 50/60 Hz

Product questions
Does the planned inverter count fit one SEC3000C?
The SEC3000C supports a maximum of 60 inverters via RS485 and 10 inverters via LAN. Check your planned inverter count against these limits.
What sits inside the cabinet, and which CTs does the meter take?
The cabinet contains an EzLogger3000C datalogger, a 15-port switch, and a GM330 smart meter. The meter takes CTs with a ratio of nA/5A, where n is the CT primary side input current and ranges from 200 to 5000. The CT cable length should not exceed 30m.
Where can the cabinet be installed?
The SEC3000C supports wall mounting, bracket mounting, and pole mounting. The installation location must be out of reach of children, protected from direct sunlight, rain, and snow, and away from strong magnetic fields. If there is a radio station or wireless communication equipment below 30MHz nearby, keep a distance of more than 30m. The altitude must be below 3000m.
