No. You do not need to install Fusebox-specific hardware. Fusebox system is hardware-agnostic and works with your existing assets and site controllers through standard industrial protocols such as Modbus, MQTT, and IEC-104. That means you can connect your site without replacing your current hardware stack. If needed, we can also provide Fusebox controllers if you do not have your own.
Absolutely. Our open API architecture allows you to plug in your proprietary tools and "secret sauce," using Fusebox system as the reliable execution and connectivity layer.
Unlike "black box" solutions, you retain 100% ownership of your data and strategy. Fusebox system acts as the infrastructure, not the owner of your operational insights.
Yes. The OS is built allowing you to manage diverse portfolios across different TSO jurisdictions and multi-market ancillary services within a single environment.
Yes. Fusebox system runs as SaaS: you operate as a tenant on our platform, and we host, maintain and update it. Where your assets, protocols or markets need it, integrations or custom modules are added on top of the same SaaS base.
PV, wind, battery storage (BESS) and flexible loads, on a single site or across a mixed fleet. Assets connect through Modbus, MQTT or IEC-104, using your own controllers or ours.
mFRR, aFRR and FCR, through 9 TSO integrations in 9 EU countries. The platform is live in 14 countries, and new TSOs are added to the same SaaS workflows rather than built per customer.
Weeks to months, not the 9-30 months an in-house build typically takes. Architecture and market fit take 1-4 weeks, then first sites are connected and validated before onboarding is replicated across the portfolio.
