Description
High-speed active power regulation across multi-inverter arrays.
GoodWe SEC1000 is a commercial smart energy controller and dynamic export limiter managing up to 60 commercial inverters, engineered to enforce strict utility grid-injection limits and reactive power compensation in real time.
High-Speed Dynamic Zero-Export Control
Measures grid feed-in at sub-second intervals and throttles multiple inverters simultaneously to prevent unauthorized grid injection.
Multi-Inverter Telemetry Aggregation
Connects and manages telemetry across commercial string inverters on a unified RS485 / Ethernet network.
Reactive Power & Phase Balancing Regulation
Dynamically adjusts inverter power factors (cos φ, Q(U)) to meet strict utility grid-code power quality requirements.
Industrial Weatherproof Enclosure (IP65)
Die-cast outdoor housing with internal circuit breaker and surge protection for harsh industrial switchyards.
More product details
Exceeding contractual grid-injection limits can result in heavy utility penalties or plant disconnection. The SEC1000 reads grid exchange at the point of common coupling, dynamically throttling inverter output in real time.
- Sub-second control loop modulates active power output across all connected inverters simultaneously.
- Ensures zero reverse power flow into the grid or maintains custom export limits (e.g., 30 kW or 100 kW caps).
- Measures three-phase facility power via external 5 A split-core current transformers.

Turnkey outdoor installation with dynamic power factor control.
Factory-assembled in a robust IP65 outdoor enclosure, the SEC1000 arrives pre-wired with internal circuit breakers, surge arresters, and communication terminals for fast switchyard deployment. Dynamically controls reactive power (cos φ, Q(U)) to stabilize local grid voltage during heavy machine cycling. Internal power supply (100–240 V AC) and overvoltage suppressors protect against lightning transients. IP65 die-cast enclosure installs cleanly on external walls or pad-mounted distribution frames (-30 to +60 °C).

What is the difference between the SEC1000 and the SEC1000S?
SEC1000 requires external meter/CTs; SEC1000S includes a built-in meter. * SEC1000: Core controller unit that interfaces with external smart meters and CTs via RS485. * SEC1000S: Includes a factory-integrated three-phase smart meter inside the IP65 enclosure, allowing direct connection of external 5 A CT leads without mounting a separate meter box.
How fast does the SEC1000 respond to sudden building load drops?
Sub-second control loop ( 1,000 ms response time).** The SEC1000 samples grid power multiple times per second and broadcasts power-limiting commands across RS485/Ethernet in under 1 second, ensuring that sudden load drops (e.g., large industrial motors shutting down) do not trigger reverse-power utility relays.
