What Heiwit does
Heiwit S.p.A. is an Italian energy storage company headquartered in Varese and Caronno Pertusella that develops, produces, and sells sodium-ion battery systems for residential photovoltaic applications. Its core product is a 10 kWh sodium-ion battery — claimed as the first commercialized sodium-ion residential storage in Europe — built without lithium or cobalt, rated at 95% efficiency, 6500+ average life cycles, 100% depth of discharge, and backed by a 10-year Italian warranty. The offering is completed by the VIRGO hybrid single-phase inverter, the LYBRA hybrid three-phase inverter, and AI-Care, an AI-powered Smart Energy Manager that optimizes self-consumption and times energy sales to favorable price windows. A HEIWIT Token 'Social Energy Cloud' initiative extends the ecosystem to users who do not own a photovoltaic system.
The company operates an exclusively B2B go-to-market through a network of authorized installers across Italy, covering regions from Puglia and Sicily to Lombardy and Tuscany, with no direct-to-consumer sales. Revenue derives from hardware sales (batteries and inverters), a managed rooftop-rental model for energy-intensive businesses with 30-year maintenance contracts and 20% commissions on installation costs and revenues, and the emerging subscription/token-based social energy cloud stream. Heiwit markets through a multilingual website, social media, a mobile app for real-time monitoring, industry events such as Solar Solutions Torino (where it won the Best Innovation Award), and certified installer training programs, with PVGIS integrated for production forecasting.

Heiwit competitors and assessment
Company assessmentDirect peers
- Pylontech: Chinese-headquartered manufacturer of LFP battery modules and rack storage systems targeting residential and small commercial ESS in Europe. Closest direct analog to Heiwit's 10 kWh modular residential battery, differing mainly on chemistry (LFP vs. sodium-ion).
- Sonnen (sonnen GmbH): German residential battery storage specialist (now a Shell subsidiary) selling lithium-based home batteries with proprietary energy management software and an installer-driven model. Directly comparable European residential storage benchmark for Heiwit.
- Enphase Energy: US-listed manufacturer of microinverters and the IQ Battery residential storage product, distributed in Europe via installer networks. Direct competitor in residential PV+storage with integrated software (Enlighten) analogous to AI-Care.
- AlphaESS: Provider of integrated residential and small-commercial energy storage systems (batteries + hybrid inverters + EMS) sold through installer channels across Europe. Highly comparable GTM and product stack to Heiwit's sodium-ion + VIRGO/LYBRA + AI-Care offering.
- SolarEdge Technologies: Israeli-headquartered provider of residential PV inverters, power optimizers, and the Energy Bank battery, heavily dependent on European installer channels. Competes with Heiwit at the inverter and integrated-storage level.
Broad incumbents
- Tesla (Energy / Powerwall): Tesla's residential Powerwall product plus the Tesla app ecosystem is the dominant incumbent in European home battery storage. A much larger, broad-line player but the primary reference point for the category Heiwit competes in.
- Huawei FusionSolar Smart PV: Huawei's residential smart PV solution bundles hybrid inverters (SUN2000), LUNA batteries, and an EMS, sold widely across European installer networks. A large, broad incumbent whose stack overlaps directly with Heiwit's battery + inverter + AI-Care offering.
- BYD: Global battery giant offering the Battery-Box Premium residential storage line distributed across Europe. Competes with Heiwit on residential battery pricing and brand, with vastly deeper manufacturing scale and broader product lines.
Emerging players
- Faradion: UK-based sodium-ion battery technology developer (acquired by Reliance) with cell-level IP applicable to stationary storage. Closest chemistry-level peer to Heiwit, though operating at the cell/IP-licensing layer rather than finished residential products.
- Altris: Swedish sodium-ion battery cell developer supplying prussian-blue-analogue cathode material and cells to European BESS integrators. Same chemistry and European-base positioning as Heiwit but at the cell layer rather than residential finished-product layer.
