Brain by FUERGY
Brain by FUERGY is an AI-driven smart battery storage system that learns a site's consumption habits, then charges and discharges autonomously to cut electricity bills, guarantee backup power and make the most of on-site renewable generation.
What is Brain by FUERGY?
Brain by FUERGY is an AI-driven battery storage system for organisations that want to cut electricity costs without rebuilding their energy infrastructure. It combines third-party hardware — batteries, inverters and battery management systems — with two components FUERGY builds itself, the Control unit and the Power mergers, plus an energy management application running on the vendor's own software platform, mosAIc.
Once a certified FUERGY installation partner has fitted the battery and connected the site's energy-intensive equipment, its renewable sources and, optionally, a Smart Charger, the system starts learning. It builds behaviour patterns from the site's consumption habits, then charges and discharges the battery on its own. Its decisions draw on battery capacity, weather forecasts, electricity exchange prices, the state of the power grid, green electricity production and other online data combined with AI predictions. The stated aims are the highest achievable savings, the fullest possible use of local green generation, enough energy to cover the site's needs, and guaranteed backup power.
Several extensions sit around that core. flexibility Brain regulates energy-intensive technologies — heat pumps, furnaces, reservoirs and tanks, HVAC systems, compressors, EV chargers — within conditions and limits agreed in advance for each one, so regulation never disturbs the delivery point or the comfort of the people relying on it. A flexibility aggregator lets an electricity supplier manage several equipped delivery points as one entity inside a single balancing group. The Smart Charger, built in cooperation with Sminn, is a modified charging station for electric and plug-in hybrid vehicles that adds vehicle-to-grid capability.
Results are followed through a web application carrying production and consumption data, savings, automated electricity plans and reports usable for ESG reporting. FUERGY takes on installation, permits, management, repairs and maintenance. The CU 24 and CU 48 control units carry an EU Declaration of Conformity, and the company holds ISO/IEC 27001, ISO 14001, ISO 45001 and ISO 9001 certificates. Published references run from 108 kWh to 1,296 kWh of installed capacity across factories, automotive plants, shopping centres, a national football stadium, office and residential buildings and a local distribution system.

When to use Brain by FUERGY / When not to
A quick filter to help you decide if Brain by FUERGY is the right fit.
When to use Brain by FUERGY
- Industrial sites with heavy, continuous electricity demand — foundries, metallurgical plants, textile and plastics factories — where peak shaving and load shifting move real money
- Businesses already running solar panels that want surpluses stored and monetised instead of fed back to the grid cheaply
- Facility and property managers of shopping centres, office buildings and retail headquarters chasing lower energy bills without capital expenditure
- Electricity suppliers wanting to aggregate flexibility across several delivery points and manage them as a single entity within one balancing group
- Operators of regulable energy-intensive equipment — heat pumps, furnaces, HVAC systems, compressors, EV chargers — that can be modulated without disrupting production
When not to use Brain by FUERGY
- Households and small businesses: the Energy as a Service route is aimed at sites consuming more than 1.5 GWh of electricity a year
- Buyers who need a published price before they will engage, since nothing is public and every route ends at a sales consultation
- Teams looking for a software-only product, because Brain is hardware that a certified partner must install on site
- Developers expecting an API, an SDK or developer documentation, none of which exists
- Organisations far outside Slovakia and Czechia, where the published references and supplier partnerships are concentrated
How to use Brain by FUERGY
A typical end-to-end flow, from setup to results.
- Request a free consultation through the battery storage enquiry form on the site
- Have FUERGY run an energy analysis of the site to size capacity and output against annual consumption
- Agree the commercial route: outright installation, or Energy as a Service rental with no initial investment
- Let a certified FUERGY installation partner install the battery and configure the system
- Connect energy-intensive equipment, on-site renewable sources and, if wanted, the Smart Charger
- For flexibility Brain, define the conditions and limits within which each technology may be regulated
- Let the AI learn the site's consumption habits and build its behaviour patterns
- Leave the system to charge, discharge and regulate autonomously against live prices and grid status
- Track savings, production and consumption in the web application
- Ask for technology activation to be switched to manual mode if automatic control ever needs overriding
Pros & Cons
Pros
- A complete certification set held by FUERGY — ISO/IEC 27001, ISO 14001, ISO 45001 and ISO 9001, issued by TAYLLORCOX
- An EU Declaration of Conformity published for the CU 24 and CU 48 control units
- Twenty-five named and quantified customer references, from 108 kWh to 1,296 kWh, across varied sectors
- Financing models that remove upfront capital expenditure, including rental under Energy as a Service
- flexibility Brain costs the customer nothing, the savings being redistributed by the electricity supplier
- Installation, permits, paperwork, management, repairs and maintenance all handled by the vendor
- Personal data stored on servers located in the Slovak Republic, inside the European Union
Cons
- No public pricing of any kind: no pricing page exists, and the sitemap confirms the absence
- Energy as a Service is gated behind annual consumption above 1.5 GWh, ruling out smaller sites
- A heavy hardware deployment that depends on a certified installation partner and on-site work
- No API, no developer documentation and no mobile application
- Website and product material in English and Slovak only, with references concentrated on Slovakia and Czechia
- The privacy policy covers the website alone and says nothing about the energy data the product collects on site
- No stated retention period, no data processing agreement and no published list of subprocessors
Pricing & Plans
No price is published. FUERGY operates on a quotation basis: there is no pricing page, and every route through the site leads to a free consultation form rather than a rate card. Two commercial arrangements are described without figures. Under Energy as a Service the smart battery storage is rented with zero initial investment, an arrangement offered to sites whose annual electricity consumption exceeds 1.5 GWh; solar panels leased on the same basis are said to yield total cost savings of 5 to 10 percent. Under flexibility Brain the customer pays nothing at all, the savings generated being redistributed by the electricity supplier. Neither a permanent free plan nor a free trial of the product is offered, and the starting price, currency and billing unit are consequently all left empty.
Data, GDPR & hosting
A consolidated view of how Brain by FUERGY handles your data.
GDPR overview
GDPR implementation is explicit and specific. The privacy policy names Regulation (EU) 2016/679 alongside Slovak Act No. 18/2018 on personal data protection, and provides that where the policy is silent or diverges, the Regulation and the Act prevail regardless. Data subject rights are enumerated: access, rectification, erasure with its six grounds, restriction of processing, objection, portability where technically feasible, and the right not to be subject to a decision based solely on automated processing, profiling included. Legal bases are set out one by one. The supervisory authority is named — the Office for Personal Data Protection of the Slovak Republic, under Section 100 et seq. of Act No. 18/2018 — and privacy@fuergy.com is given for questions. No data protection officer is designated, and no Article 27 representative appears, which is consistent with a controller established in the Union.
Who owns the data?
The published privacy policy governs the fuergy.com website rather than the energy data the product collects, and it names FUERGY Industries j.s.a. as the controller. It covers what visitors hand over: email addresses for the newsletter, and names, emails and telephone numbers submitted through contact forms. The company states it will not share, sell or give away personal information except in four listed situations — a disclosure believed to be required by law, sharing among its parents, affiliates and companies under common control, sharing with the user's consent, and sharing of aggregated or anonymised data. No clause addresses ownership of the consumption data Brain gathers at a customer site.
Reuse rights
Nothing in the terms of use grants a visitor any reuse right. Trademarks, service marks, trade names, logos and domain names are described as the sole property of their respective owners, and the terms state plainly that they grant no right to use those brand features, commercially or otherwise. Automated extraction is forbidden outright: users may not employ any robot, spider, crawler, scraper or interface the company has not itself provided to reach the site or pull data from it. On its own side FUERGY lists its purposes — delivering the service, answering enquiries, sending administrative information, requesting feedback, marketing, protecting the site, identifying usage trends, protecting vital interests, and meeting archiving and statistical obligations — resting on consent, legitimate interests, legal obligations and vital interests. Marketing emails can be opted out of and consent withdrawn at any time. Whether customer data ever feeds AI model training is never addressed.
Data retention & training
Hosting summary
The privacy policy is unusually direct about location: personal data is transferred, processed and stored on servers located in the Slovak Republic. That places it inside the European Union and under Slovak jurisdiction, alongside Regulation (EU) 2016/679 and Slovak Act No. 18/2018. The website itself resolves to 37.9.175.180, an address operated by WebSupport s.r.o. in Bratislava, consistent with the declared jurisdiction. Two qualifications matter. First, FUERGY reserves the right to subcontract processing to, or share information with, third parties located in countries other than the user's own, and asks readers to acknowledge that their data may then be processed and stored abroad where they may not hold the same rights as under local law. No list of those third parties is published, so the actual chain cannot be checked. Second, the company undertakes not to transfer personal data to countries that fail to ensure an adequate level of protection. No broad hosting region is named, only the country. Nothing is said about where the energy data collected by Brain at a customer site is stored.
Things to keep in mind
Risks and trade-offs to weigh before adopting Brain by FUERGY.
- The registered office differs between pages: the disclaimer and the terms of use both give Mlynské Nivy 16, while the contact page gives Pribinova 34. Confirm which address governs before signing anything
- The partners page mixes electricity suppliers, component suppliers and customers in a single list. Vertiv, Slovalco, BILLA and Yanfeng appear there as customers, not as technology partners of the product
- The ISO certificates belong to FUERGY; TAYLLORCOX is the certification body that issued them, not a party to the product. Do not read the certifier's name as a product guarantee
- A footer link to a product called mAInchart returns an error and is missing from the sitemap, which suggests a withdrawn product still advertised on every page
- Handing automatic control of heat pumps, furnaces and HVAC to an algorithm means trusting limits set once at configuration time. Agree them carefully, and note that manual mode has to be requested
- Savings figures rest on the vendor's own case studies, with no independent verification published; treat quoted percentages as indicative until a site-specific analysis is done
- Because the system reads consumption habits continuously, a site's operating rhythm becomes legible in the data, and the published privacy policy never describes how that operational data is handled or for how long
Setup & Integrations
Technical difficulty
Setup is a physical project, not a software installation. A certified FUERGY installation partner fits the battery, configures the system and connects the site's energy-intensive equipment, renewable sources and any Smart Charger; self-installation is not offered. An energy analysis comes first, sizing capacity and output against annual consumption. For flexibility Brain, each technology's regulation conditions and limits are defined before activation. The technical burden on the customer is therefore light but the organisational one is real: FUERGY absorbs permits, paperwork, management, repairs and maintenance, while the customer provides the site, the equipment and the decisions.

Should you pick Brain by FUERGY?
Brain by FUERGY is a serious piece of industrial equipment rather than a piece of software you sign up for. The proposition is coherent: proprietary control hardware and an in-house software platform sit on top of commodity batteries and inverters, and the AI layer earns its place by arbitrating between exchange prices, weather, grid status and a site's own consumption habits. The evidence behind it is unusually concrete for this market — twenty-five named references with stated capacities from 108 kWh to 1,296 kWh, spanning foundries, automotive plants, shopping centres, a national football stadium and a local distribution system — and the certification base is complete, with ISO/IEC 27001, ISO 14001, ISO 45001 and ISO 9001 held by the company and an EU Declaration of Conformity covering the CU 24 and CU 48 control units.
The reservations are mostly about what is not said. No price appears anywhere, and the absence of a pricing page is confirmed by the site's own sitemap, so budgeting is impossible before a consultation. The Energy as a Service route excludes anything below 1.5 GWh of annual consumption. There is no API, no mobile application and no developer material. Most importantly for a product that reads a site's operating rhythm continuously, the privacy policy addresses the website alone: it is clear that personal data sits on servers in the Slovak Republic, but it never describes what happens to the energy data Brain itself collects, sets no retention period, and publishes neither a data processing agreement nor a subprocessor list.
For an energy-intensive site in Central Europe willing to enter a sales conversation, it is a well-documented option. For anyone needing transparent pricing, self-service, or written guarantees about operational data, the gaps should be closed in writing first.
