GoodWe SEC1000 - plant communication controller 100–480 V.
Description GoodWe SEC1000
GoodWe SEC1000 is a communication controller for solar plants running more than one inverter. The device collects data from all the plant's equipment, consolidates it into a single picture and manages the system as a whole. Metal housing with IP65 protection, dimensions 320 × 420 × 131 mm, mass 4 kg, supply 100–480 V, operating temperature from −30 to +60 °C.
When one inverter is no longer enough
A domestic installation of a few kilowatts manages without a controller: the inverter talks to the cloud itself and limits export itself using meter data. But as soon as there are several inverters, tasks appear that none of them solves alone.
The principal one is coordinated control. Each inverter sees only itself and has no idea how much its neighbours are producing. Without a common conductor the plant can neither hold total export within prescribed limits nor distribute load between converters correctly.
What the controller does in practice
collects telemetry from every inverter in the plant at one point;
limits total generation according to the connection terms, rather than each inverter separately;
transmits data to the monitoring system — for the owner and the maintenance company;
executes dispatch commands where the network operator requires remote power control;
keeps an archive of events and readings, used to investigate abnormal situations.
IP65 and operation from −30 °C
IP65 protection means resistance to dust and water jets, while a lower operating limit of −30 °C covers any winter in this region with margin to spare.
The practical conclusion: the controller can be mounted directly on the plant site — beside the inverters, on a structural support, on the exterior wall of a technical block. Neither a heated room nor a separate enclosure with heating is required. For ground-mounted plants out in a field that is fundamental: the nearest building may be a kilometre away.
A metal housing, and why that is no trifle
The housing is metal rather than plastic. For equipment standing in the open for years that is a noticeable difference: metal does not lose its properties to ultraviolet, does not yellow and does not crack in frost after a few seasons.
A mass of 4 kg and compact dimensions allow one person to install the device on ordinary fixings. The wide 100–480 V supply range simplifies connection: the controller works from a single-phase supply and from line voltage alike, with no additional converters.
What to clarify before ordering
The key selection parameters for a controller are the maximum number of inverters it serves, the communication protocols supported, and compatibility with your specific equipment series. This information is in the manufacturer's documentation and should be checked before purchase.
Give separate thought to the communication channel to the plant. If the site has no wired internet, the range includes versions with a built-in modem — removing the need to build a separate communication link across a field.
Tell us what your plant consists of — the number and models of inverters, whether the site has internet, and the network operator's requirements. We will select a controller that covers the task, and warn you if a simpler solution would do for your configuration.
