What sun2wheel does

sun2wheel AG is a Swiss private limited company founded in 2019 that develops bidirectional EV charging technology and virtual power plant software for the Swiss market. Its core platform, BidiX, aggregates photovoltaic systems, battery storage, and electric vehicles into a virtual power plant that delivers grid stabilization services and helps owners earn higher yields on their solar assets. The product portfolio comprises the BidiX virtual power plant, the sun2wheel Controller (an intelligent energy and load management gateway deployable via cloud and edge), a bidirectional DC wallbox supporting Vehicle-to-Home (V2H), Vehicle-to-Grid (V2G), smart-charging, and surplus-charging modes, and a V2X Controller mobile application available on iOS and Android.

The company generates revenue through three primary streams: hardware sales of its bidirectional DC wallbox (distributed through channel partner EV2Grid), subscription-based BidiX platform services for PV system owners seeking higher revenues and protection against negative feed-in tariffs, and usage-based revenue shares from grid stabilization services delivered to distribution network operators. Its go-to-market is hybrid: direct digital channels (blog, newsletter, social, mobile app stores) for consumer awareness and acquisition, complemented by channel partnerships with EV2Grid for hardware sales and TCS for member-focused EV charging distribution. Enterprise customers include TCS (Swiss motoring club distributing residential charging solutions to its members) and DPD Switzerland (logistics fleet electrification using sun2wheel intelligent charging management).

Sun2wheel positions itself as an early mover in Switzerland's bidirectional charging market, leveraging proprietary algorithm technology that the company describes as the foundation of BidiX. With approximately six team members plus a board director (Sandro Piffaretti), the company is founder-led and privately held with no disclosed external investors. It is actively positioning its offering around the upcoming 2027 Swiss regulatory change that may allow distribution network operators to compensate PV feed-in at spot prices potentially below zero, framing BidiX as a hedge through coordinated energy management. Memberships in Swiss Cleantech, Swiss eMobility, Energiecluster, and Handelskammer beider Basel anchor its participation in Swiss energy and mobility policy communities.

Core offering

sun2wheel builds and operates the BidiX virtual power plant platform that aggregates PV installations, battery storage, and electric vehicles for grid stabilization and revenue optimization. The company sells bidirectional DC wallboxes (V2H/V2G charging) and the sun2wheel Controller (intelligent load and energy management gateway with cloud and edge deployment), distributed in Switzerland primarily through channel partner EV2Grid and complemented by the V2X Controller mobile app.

Product overview

sun2wheel offers a unified portfolio of energy management products centered around its virtual power plant BidiX. The core offering consists of the sun2wheel Controller (intelligent load and energy management hardware/gateway), paired with a bidirectional DC wallbox for EV charging/discharging. These products work together within the BidiX virtual power plant platform to optimize self-consumption, enable grid services (V2H, V2G), and manage PV curtailment. The V2X Controller mobile app provides user-facing control and monitoring. The company positions itself as building digital power plants without turbines, coal, or nuclear fuel, leveraging assets from residential and industrial customers.

Direct peers

• Fermata Energy: Fermata Energy provides bidirectional charging software and hardware for V2G applications, with focus on fleet operators. Closely comparable to sun2wheel's combined bidirectional wallbox and BidiX platform offering for both residential and fleet use cases.
• Wallbox: Wallbox manufactures bidirectional EV chargers (Quasar 2) and operates an energy management platform, directly competing with sun2wheel's bidirectional DC wallbox and V2X Controller across residential and fleet segments in European markets.
• The Mobility House: The Mobility House operates ChargePilot, an EV charging and energy management platform with V2G readiness, plus bidirectional charging hardware partnerships. Targets European residential and fleet markets with comparable value proposition to sun2wheel.
• Nuvve: Nuvve operates a V2G aggregation platform that coordinates EV batteries for grid services, directly comparable to sun2wheel's BidiX VPP. Both companies target fleet operators and distribution network operators with grid services revenue share models.

Emerging players

• Kiwigrid: Kiwigrid provides white-label energy management software integrating PV, storage, and EV charging for European utilities and energy retailers. Directly comparable to sun2wheel's Controller and BidiX platform at the software/EMS layer.

Broad incumbents

• Tesla Energy: Tesla's energy business (Powerwall, Autobidder VPP platform, future V2G-enabled vehicles) is a broad incumbent competing across the same value chain. Significantly larger capital base and brand recognition make Tesla a key competitor for fleet and premium residential VPP business.
• Enphase Energy: Enphase offers solar microinverters, IQ Batteries, and EV chargers with its IQ Energy Router for bidirectional charging. The company competes in residential solar + storage + EV management with vastly greater resources.
• GridPoint: GridPoint provides distributed energy resource management and VPP software for commercial buildings and fleets in North America. Comparable VPP platform functionality to BidiX, though US-focused versus sun2wheel's Swiss focus.
• Sonnen (sonnenVPP): Sonnen operates sonnenVPP, aggregating residential batteries into virtual power plants across European markets. Comparable VPP aggregation model targeting distributed energy resources, though primarily battery-focused rather than EV-focused like sun2wheel's BidiX.

Regional players

• Lichtblick: Lichtblick operates one of Germany's largest virtual power plants aggregating distributed energy assets. Comparable business model to BidiX for grid services, though Lichtblick primarily operates in the German market rather than Switzerland.
