Become a partner
The Curtailer sits at the device level, on the customer's own installation, and does not depend on any inverter manufacturer exposing an API. That makes it a control point you can reach on assets that are otherwise out of reach - whichever inverter brand happens to be on the roof.
Who we work with
Three shapes of collaboration, each with a different reason to want device-level control.
Negative-price hours are where a solar feed-in contract hurts both sides. Offering curtailment alongside the contract turns those hours into a non-event for your customer and removes the exposure you are pricing in today.
Portfolios stall on the assets whose inverters have no usable cloud API, or five different ones. A device-level controller gives you a single, uniform way to shut export down across the whole portfolio, ahead of the settlement hour.
Congestion markets need volume, and a lot of it sits in installations too small to justify the hardware cost of reaching them today. Pricing per Curtailer brings that capacity within reach, so single-inverter, residential-scale sites can join the same flex pool as your larger assets.
What a partnership looks like
We are a small team and shape each partnership around what you actually need - but these are the four pieces most conversations start from.
A REST API over your Curtailers, so curtailment decisions can come from your trading desk, EMS or dispatch platform rather than from ours.
Curtailers grouped under your account instead of one login per customer, with status and performance across the fleet in one place.
Volume supply of Curtailer Mini wifi or Curtailer Mini wifi ext, with DIY, installer or full-service installation depending on what your customer base expects.
Referral, reseller or co-branded - including how the subscription is billed and who owns the customer relationship. Open to discussion.
Why device-level control travels further
Curtailment that runs through an inverter manufacturer's cloud API only ever covers the brands that API has integrated, and breaks when the API changes. That is a poor foundation for a portfolio you do not get to choose the hardware for.
The Curtailer works electrically - DRM, Modbus over TCP or serial, or a simple 2-pin digital input - so the same controller and the same integration keeps working across an installed base you inherited rather than specified.
Not sure which of the three you are, or want to sketch something that does not fit the list? A short call is usually the fastest way to find out.
