What Ferroamp Elektronik does
Ferroamp Elektronik (legal entity Ferroamp AB (publ), ticker FERRO on Nasdaq First North Growth Market) is a Sweden-based greentech hardware and software company founded in 2010, headquartered in Sundbyberg, Stockholm, with 51-100 employees. It develops, manufactures, and markets a modular DC-grid energy management system centered on the EnergyHub intelligent inverter, supported by Solar String Optimizers (SSO) for PV yield, Energy Storage Optimizers (ESO 6 kW commercial / ESO 15 kW home) for battery control, and the FerroAI/EnergyCloud software layer for AI-assisted optimization and monitoring. The system is differentiated by a proprietary 760V DC bus architecture, dynamic phase balancing, and the patented PowerShare capability that allows electricity to be shared between multiple buildings on a common DC grid.
The company serves three primary customer segments — villaägare (homeowners), bostadsrättsföreningar (tenant-owner associations/BRF), and fastighetsägare (commercial property owners) — and sells exclusively through a certified installer partner network across Sweden, supplemented by a Maple Energy design partner for PowerShare engineering. A channel partnership with Vattenfall Försäljning signed in December 2025 broadens distribution to start in 2026, and the company has built an ecosystem of verified integrations (CTEK via OCPP 1.6-J, SolarFox, Pylontech batteries, three open APIs including CloudAPI, Modbus TCP, and Ext-API/MQTT). Revenue is generated primarily through hardware sales (EnergyHub, SSO, ESO, batteries, V2X, Emergency Power, accessories), with secondary recurring streams from PowerShare licensing fees and EnergyCloud/FerroAI services, plus a transactional angle on ancillary grid services (stödtjänster) via Svenska kraftnät. Pricing is not publicly disclosed and is set on a project basis by certified installers.

Ferroamp Elektronik product offering
Product offeringCore offering
Ferroamp designs, manufactures, and sells a modular DC-grid energy management platform for residential and commercial properties. Its EnergyHub intelligent inverter connects and orchestrates Solar String Optimizers (SSO), Energy Storage Optimizers (ESO), AI-based FerroAI control, and the patented PowerShare technology for sharing electricity between buildings. Ferroamp hardware, software, and services are sold exclusively through a network of certified installer partners in Sweden.
Product overview
Ferroamp offers a modular, scalable energy management system for residential and commercial properties. The core platform centers on EnergyHub, an intelligent inverter that orchestrates interconnected components: Solar String Optimizers (SSO) for solar panel optimization, Energy Storage Optimizers (ESO 6kW/15kW) for battery control, and FerroAI for AI-driven optimization. The system integrates with batteries (Pylontech Force H3, ESS), Emergency Power backup units, and V2X bidirectional EV charging. Users monitor and control via EnergyCloud platform and mobile app. A proprietary DC-grid architecture enables PowerShare for sharing energy between buildings. The system targets homeowners (villas), tenant-owner associations (BRF), and property owners, with recent Vattenfall distribution partnership.
