GoodWe SEC1000S - plant communication controller 100–480 V.
Description GoodWe SEC1000S
GoodWe SEC1000S is a communication controller in the 'S' variant for solar plants running several inverters. The device acts as an intermediary between the plant's equipment, the owner and the network operator. Metal housing with IP65 protection, dimensions 320 × 420 × 131 mm, mass 4 kg, supply 100–480 V, operating temperature from −30 to +60 °C.
Three roles in one device
A plant controller performs three tasks of quite different character, and it is worth keeping them apart, because each carries its own value.
Data collection. The device polls every inverter on the plant and forms a single telemetry stream. Without it each inverter has to be examined separately and no consolidated picture exists.
Generation control. The controller holds the plant's total export within prescribed limits, distributing the constraint among inverters. None of them can do this alone, because none knows what the others are doing.
Executing external commands. Where the network operator requires remote power control, it is through the controller that the requirement is met.
IP65 as a precondition for field mounting
Protection against dust and water jets, combined with a lower limit of −30 °C, means the device requires neither a building nor a heated enclosure. It is installed directly on site: on a structural support, on an exterior wall, beside the inverters.
For ground-mounted plants that is not convenience but necessity. Equipment sits out in a field, the nearest building may be a kilometre away, and nobody will construct a technical block for the sake of one controller. A metal housing, unlike plastic, does not degrade under ultraviolet within a few seasons.
A 100–480 volt supply
This wide range solves a practical installation problem. The controller can be connected to whatever source is available on site — a single-phase auxiliary line, line voltage, or the inverters' supply circuit.
The designer need not specify a separate transformer or power supply unit, and the installer is not dependent on which voltage happens to be nearest the mounting position. On a large site that saves both time and cable.
What full monitoring gives the owner
actual output per inverter, rather than a single figure at month end;
early detection of deviations — panel soiling, degradation, partial shading;
a documented event history for investigating emergency shutdowns;
evidence for warranty claims backed by figures rather than by 'it runs badly'.
What to clarify before buying
Within the series, controllers differ in the number of devices served, the set of interfaces and whether a modem is built in. These parameters determine suitability for a particular plant and must be checked against the manufacturer's documentation.
If you are still designing the plant, settle the communications question at once: with no wired internet on site you will need either the modem version or a separate data channel. Building that into the design costs less than solving it after installation.
Send us the plant configuration — the number and models of inverters, available connectivity and the network operator's requirements. We will verify compatibility against the documentation and advise which controller variant suits your site.
