GoodWe SEC3000 (central plant controller, without switch)

GoodWe SEC3000 is the central plant controller of the SEC3000 pair: monitoring and real-time data collection for up to 60 inverters, without the built-in switch.

  • Four RS485 ports to 60 inverters, two RJ45 Ethernet at 10/100 Mbps, 4G optional — the full controller function without paying for a switch you already have.
  • IP66 and C5L anti-corrosion, rated -30 to +60 °C, so it can live outdoors on a coastal or industrial site.
  • EzLogger3000C datalogger and GM330 smart meter included; metering range covers 172-415 V line voltage on 3L/N/PE and 100-240 V on 3L/PE.
  • CE-RED (EN18031) and RCM certified, under 15 W, 11 kg — a third lighter than the C.

Plant logic

Peak shaving is a schedule, not a hope.

One controller coordinates inverters, meters and tariff windows across the plant.

Four RS485 ports to 60 inverters, two RJ45 Ethernet at 10/100 Mbps, 4G optional — the full controller function without paying for a switch you already have.
IP66 and C5L anti-corrosion, rated -30 to +60 °C, so it can live outdoors on a coastal or industrial site.
EzLogger3000C datalogger and GM330 smart meter included; metering range covers 172-415 V line voltage on 3L/N/PE and 100-240 V on 3L/PE.

Every figure comes straight from the manufacturer's official datasheet.

Selection 1

The C adds a built-in network switch. Everything else that matters is the same controller.

  • SEC3000 (this one): no switch, 11 kg, C5L anti-corrosion.
  • SEC3000C: 15-port switch, 16.9 kg, C5M anti-corrosion.
  • Both: four RS485 ports, 60 inverters, IP66, EzLogger3000C, GM330.
  • Order this one if the cabinet already has a switch, the C if it does not.

Configuration 1

Real-time data collection across the plant, aggregated to the portal.

  • Up to 60 inverters over four RS485 buses, so the string count does not force a second controller.
  • The included GM330 measures at the point of connection: 172-415 V line voltage on 3L/N/PE, nA:5A current with a ratio between 200 and 5000.
  • Two Ethernet ports and optional 4G give a fallback path off site.

Installation & wiring 1

Yes. IP66 with C5L anti-corrosion and a -30 to +60 °C range.

  • Wall, bracket or pole mounting.
  • If the site is coastal or heavily industrial, the SEC3000C's C5M class is the higher of the two — worth raising on the quote.
  • CE-RED (EN18031) and RCM certified.

Delivery 1

From de-linker's own published prices for the two components GoodWe lists inside it.

  • EzLogger3000C at 560 plus GM330 at 118 = 678.
  • That lands below the SEC3000C's published 705, which is the correct direction: the C adds a 15-port switch and a higher corrosion class.
  • Parcel or half pallet at 11 kg net. B2B net; confirmed on the quote.
