What Accuselect does
Accuselect B.V. is a Netherlands-based, venture-backed private company founded in 2022 by three TU Delft alumni (Paul Schellekens, CEO; IJsbert Bekooy, COO/CFO; Melanie de Reus, CCO) that provides an end-to-end home battery service across the Dutch market. The company is the official Dutch distributor of two European home battery brands — GivEnergy (UK) and Sonnen (Germany) — and layers a proprietary cloud-based Energy Management System called Powerselect® on top of the hardware to automate charging and discharging for solar self-consumption, dynamic price arbitrage on the EPEX day-ahead market, and imbalance market trading in collaboration with energy suppliers. Accuselect serves three distinct customer segments in parallel: residential homeowners with solar panels seeking higher self-consumption and energy-cost reduction; certified installation companies purchasing hardware and receiving training, certification, and a white-label savings calculator; and energy market actors (energy suppliers and grid operators) that consume Powerselect's fleet-level flexibility through a public REST API.
Powerselect® is the technical centrepiece. It is a brand-agnostic, cloud-only EMS that requires no additional hardware at the customer premise — all control happens via cloud-to-cloud integrations with compatible batteries. The platform is built primarily in Python and exposes three automated control strategies: dynamic hourly price optimisation, imbalance market participation (today via Frank Energie), and self-consumption optimisation that is reported to raise the share of solar energy used on-site from approximately 30% to 70%. The product surface comprises a consumer mobile application (live on iOS and Android), a partner portal at installateur.accuselect.nl for installers, a public REST API for energy suppliers, and a white-labelled savings calculator embedded at start.accuselect.nl. The company is also developing an open-source S2 Resource Manager (EN 50491-12-2) under the TKI Urban Energy S2Adopt project to standardise home battery communication.
The business model combines one-time hardware revenue (battery systems starting at €3,350 including installation, with capacity from 2.6 kWh to 55 kWh) with B2B distribution to installers and energy suppliers, training and certification programmes delivered with manufacturer partners, and managed-services/API revenue from energy suppliers that pay for access to the aggregated battery fleet. Distribution is delivered through a nationwide certified installation partner network, direct-to-consumer marketing (free advisory calls, Trustpilot-reviewed sales, content/SEO), and B2B API access. Accuselect reports more than 250 Powerselect-connected households, average customer savings of approximately €896 per year, and payback periods of 4–9 years. Named strategic partners include Frank Energie, Alliander, TNO, and the Sonnen and GivEnergy manufacturers, and the company has stated a public goal of becoming the largest home battery platform in the Netherlands by 2027.

Accuselect competitors and assessment
Company assessmentBroad incumbents
- sonnen (Shell): German home battery market leader (150,000+ installations, now part of Shell). Accuselect is its NL distributor, but sonnen operates its own sonnenBatterie EMS and sonnenCommunity virtual power plant, making it both a supplier and a broad incumbent competitor in residential battery + energy services.
- SolarEdge: Global residential solar inverter + DC-optimized battery + integrated energy management platform. Comparable end-customer (residential solar/battery owners) and overlapping home energy management functionality, though at much larger scale and with proprietary hardware.
- Enphase Energy: US-listed global provider of microinverters, the IQ Battery storage product, and the Enphase App energy management system. Directly comparable on residential battery + EMS combination, with a much broader geographic and product footprint.
- Tesla Energy (Powerwall): Global home battery (Powerwall) integrated with the Tesla app for energy management, time-of-use optimization, and virtual power plant programs. Comparable residential battery + EMS proposition at massive global scale.
- SMA Solar Technology: Global inverter giant with home energy management products (Sunny Home Manager, SMA Energy Meter) and battery-ready inverters. Comparable residential energy management focus with much broader geographic reach and an installed hardware base.
Regional players
- E3/DC: German residential battery + solar + energy management provider (subsidiary of Hager Group). Comparable residential battery + integrated EMS offering, primarily serving the German market rather than the Netherlands.
- Solarwatt: German residential solar + home battery (MyReserve) + EnergyManager provider. Comparable integrated residential storage + energy management offering, focused on the DACH market.
- SENEC: German home battery + virtual power plant operator (SENEC.Cloud) now part of EnBW. Comparable residential battery + cloud energy management + grid-services proposition, primarily operating in Germany.
Direct peers
- Stekker: Dutch home battery + smart charging startup, fellow partner in the S2Adopt TKI Urban Energy project. Most directly comparable peer — same geography, same residential home-battery + EMS focus, same B2B installer channel.
- Tibber: Norwegian-origin dynamic-pricing energy retailer expanding into the Dutch market with home energy management hardware (e.g., Tibber Pulse). Directly comparable on dynamic-pricing energy + home energy management overlap in NL.
