GoodWe SEMS Portal: automatic curtailment on IBEX prices

GoodWe plants are monitored in SEMS Portal, and since January 2026 GoodWe has also offered its new SEMS+ platform. TokPirate works through your plant’s cloud access: it tracks 15-minute IBEX prices, curtails your GoodWe inverters below your minimum and restarts them when the price recovers.

01Automation

What TokPirate does with your GoodWe plant

  • 01

    Curtails below your minimum price

    For every 15-minute IBEX interval we compare the price with your threshold. When it’s lower, we limit your GoodWe inverters through SEMS Portal – smoothly, without a hard shutdown.

  • 02

    Restarts automatically

    As soon as the price is back above your threshold, production resumes. No need to log in to SEMS Portal and do it by hand.

  • 03

    Schedules for your trader

    Planned curtailments go into the day-ahead schedule we send to your trader automatically. Less imbalance, no manual e-mails.

  • 04

    Profit after fees

    Every 5 minutes you see the plant’s real revenue – after balancing, grid access and admin fees.

  • 05

    Real-time alerts

    Push and e-mail alerts on lost connection, inverter faults or voltage deviations.

  • A sample day

    Sample data
    Price below your threshold from 11:15 to 14:30 → the plant is curtailed for 13 fifteen-minute intervals, then runs again.

02Requirements

What you need to connect GoodWe

We need access to the plant in GoodWe’s cloud with control rights – curtailment can’t be carried out from a monitoring-only account. When you sign up, tell us whether your plant is in SEMS Portal or has already moved to SEMS+, so we can give you the right instructions.

  • Your GoodWe inverters registered in SEMS Portal and sending data
  • Access to the plant in SEMS Portal with control rights – view-only isn’t enough
  • A working internet connection at the plant
  • The minimum price below which you don’t want to sell
  • Your trader’s contact details, if you want schedules sent straight to them

Not needed: new hardware, a site visit or replacing your inverters.

04FAQ

Questions about GoodWe SEMS Portal

More questions? See the full FAQ or write to us.

My plant has already moved to SEMS+. Does that matter?
Let us know when you sign up. SEMS+ is GoodWe’s new platform, launched globally on 6 January 2026, and, according to GoodWe, historical data is kept during the transition. We check the connection with you before the automation takes over.
What happens if SEMS loses contact with the plant?
Curtailment commands reach the inverters through the cloud, so they can’t be carried out without a connection. TokPirate alerts you when the link drops, so you can check the site’s internet or communication in time.
Is curtailment safe for my GoodWe inverters?
Yes. We use the manufacturer’s standard power-limiting function – the same one you could set by hand in SEMS Portal. Output is reduced smoothly rather than switching the inverters off abruptly.
How much does TokPirate cost for a plant with GoodWe inverters?
Pricing depends on the number of inverters, not the brand: Start (up to 5 inverters) at €19/month, Pro (up to 25 inverters) at €69/month and Business (up to 100 inverters) at €199/month – or €15, €52 and €149 a month billed annually. Custom (over 100 inverters) is priced on request. Prices exclude VAT, and the first 14 days are free, no card required. See pricing.
