GoodWe SEC3000C Smart Energy Controller
SEC3000C is not a single device — it is a pre-built IP66 cabinet.
- SEC1000S: export power control and parallel control for up to 10 ET 5-10 kW inverters, with a built-in GM3000 meter.
- SEC3000C: parallel connection for GoodWe on-grid and hybrid inverters, up to 60 (RS485) / 10 (LAN) units, with a built-in GM330 meter — no separate meter or 4G router needed.
- EzLogger3000C: C&I data acquisition and protocol conversion for up to 100 mixed old/new inverters.
- EzManager3000: single-site smart home EMS controlling up to 1 hybrid inverter, 2 EV chargers, 1 heat pump and 12 Shelly devices.

Peak shaving is a schedule, not a hope.
One controller coordinates inverters, meters and tariff windows across the plant.
Inspect it before you spec it.

GoodWe family. Same engineering, different size.
Every figure comes straight from the manufacturer's official datasheet.
Configuration 3
Four different roles; pick by plant size and what you are controlling.
- SEC1000S: export power control and parallel control for up to 10 GoodWe storage inverters, with EzLogger Pro, GM3000 meter and CT adapter built in.
- SEC3000C: C&I cabinet for up to 60 inverters over RS485 (20 per port) or 10 over LAN, with a GM330 meter and EzLogger3000C pre-wired.
- EzLogger3000C: the logger alone, up to 100 connected devices, for control panels you build yourself.
- EzManager3000: residential HEMS gateway for one hybrid inverter plus EV chargers and a heat pump.
They share one chassis and one datasheet but serve different plants, so check the suffix before ordering.
- SEC1000S: storage variant, parallel control of up to 10 GoodWe ET / ET PLUS+ hybrids.
- SEC1000: on-grid variant for string-inverter plants, up to 60 inverters.
- Label: the storage unit is printed 'Storage Only' on the housing.
- Mixed C&I plants: the SEC3000C supports mixed parallel of C&I hybrid and grid-tied inverters from ARM 04.
Yes, that is its role: it supports an on-grid inverter and a storage inverter running in parallel, so the existing PV keeps working while storage and flexible loads are added.
- Devices: up to 2 EV chargers, 1 SG-Ready heat pump and 12 Shelly devices, scheduled together in the SEMS+ app.
- Tariffs: dynamic and negative electricity tariffs are supported, with auto-connection to trading platforms and AI-optimised, habit-based scheduling per GoodWe.
- Hardware: DIN-rail gateway on a 12 V DC supply; GoodWe lists a 100 to 240 V power adapter for it.
Installation & wiring 1
Meter and logger are built in; per GoodWe's datasheet the current transformers for the SEC1000S are not.
- CTs: the SEC1000S takes compatible nA:5A CTs that are not supplied; budget them with the unit.
- Power: the SEC1000S accepts 60 to 280 Vac; the SEC3000C 100 to 240 V; consumption is 10 W and 25 W or less respectively.
- Mounting: the SEC1000S is IP65 for wall, bracket or pole mounting at -25 to +60 C; the SEC3000C is an IP66 wall-mounted cabinet rated -30 to +60 C.
Operation & warranty 1
Protocol conversion is the EzLogger3000C's job, whether inside the SEC3000C cabinet or on its own.
- Northbound: Modbus-TCP and IEC 60870-5-104 over Ethernet; Modbus-RTU on the four RS485 ports.
- Capacity: up to 100 connected devices, counting meters, ripple-control receivers and PT100/PT1000 sensors, not only inverters.
- Monitoring: the SEC3000C reports to the SEMS portal and a third-party system simultaneously, with third-party control over Modbus.
- I/O: 4 DI, 2 DO and 4 AI on the logger for plant signals.
Availability & compliance 1
GoodWe lists radio and cybersecurity certificates for the SEC3000C, EzLogger3000C and EzManager3000.
- SEC3000C and EzManager3000: CE-RED (EN18031) and RCM.
- EzLogger3000C: CE-RED (EN18031), RCM, FCC, ISED, Anatel, KC, MIC, VCCI and WPC, plus ETSI EN 303 645 cybersecurity compliance.
- Grid code: grid-connection certificates sit with the inverters, not the controller; confirm the complete certificate set for your project with the quote.
General 1
No.
- GoodWe builds a GM330 smart meter and an EzLogger3000C into the SEC3000C cabinet, already wired.
- That is what makes it an all-in-one: you are buying the meter, the logger, the switch, the 24 V supply and the surge protection as one commissioned assembly.
