Fusebox system vs 1KOMMA5°

EXECUTIVE SUMMARY

Who each solution is for

Fusebox system (Fusebox Energy)

A neutral, modular EMS + VPP operations platform for energy companies, BRPs/BSPs, aggregators, EPCs and asset owners that operate hybrid portfolios of PV, BESS, wind and flexible loads. Fusebox is designed to keep BRP/BSP and customer control in-house (or with chosen partners) while running site-level EMS, portfolio aggregation and market execution through a hardware-agnostic, multi-tenant platform.

1KOMMA5°

A fast-growing residential and small C&I energy solutions provider that sells and installs PV, home batteries, EV chargers, heat pumps and home energy management, then aggregates these assets into VPP and flexibility offerings under its own brand. The centre of gravity is end-customer solutions (B2C prosumers and small businesses), especially in Germany and other European countries where it is expanding.

When to choose Fusebox system

Choose Fusebox system if you are a utility, BRP/BSP, aggregator, EPC, IPP or asset fund that:

  • Focuses on C&I, industrial, hybrid and utility-scale assets rather than residential installation.

  • Wants a neutral EMS + VPP platform to run your own flexibility business rather than adopting another company’s brand ecosystem.

  • Needs to orchestrate portfolios across multiple TSOs and markets with white-label and multi-tenant capabilities.

  • Requires demand response and flexibility from consuming assets as a first-class capability.

  • Wants broad asset coverage and scaling from utility-scale down to C&I and smaller assets, including aggregator-of-aggregators models.

  • Wants fast time-to-revenue, typically 1–6 months depending on whether new TSO connections must be built.

  • Values proven delivery: 11 years in market and experience integrating 100+ different asset types into tradable portfolios.

When to choose 1KOMMA5°

Choose 1KOMMA5° if you are a residential customer, small business, or a partner focused on the prosumer segment and:

  • Want a turnkey energy solution bundle (PV + battery + EV + heat pump) with home EMS and tariffs.

  • Prefer one brand to handle hardware, installation, and ongoing services.

  • Are comfortable adopting their hardware choices and ecosystem rather than building a neutral platform capability.

WHERE FUSEBOX SYSTEM WINS

Questions

Fusebox is built for operators who run portfolios and flexibility products across C&I, industrial and utility-scale assets. 1KOMMA5° is built around selling and operating end-customer energy kits and aggregating its own installed base.

WHERE 1KOMMA5° WINS

Turnkey prosumer energy solution

For households and small businesses, a single bundled offer that includes hardware, installation, home EMS and tariffs can be simpler than assembling a multi-vendor stack.

Strong consumer brand and installation engine

A scaled installer network and consumer-facing brand can accelerate adoption in the residential segment.

High-volume prosumer aggregation

1KOMMA5° is optimised for managing many small endpoints and aggregating them under one brand program, which is relevant for B2C-oriented strategies.

IDEAL CUSTOMER FIT BREAKDOWN

Who should choose Fusebox system

  • Utilities, BRPs/BSPs, aggregators, EPCs, IPPs and asset funds operating C&I, industrial and utility-scale portfolios across multiple TSOs and countries.

  • Organisations building their own EMS + VPP products and needing white-label and multi-tenant capability.

  • Teams that want vendor-neutral integrations and long-term control over commercial model, partners and technology stack.

Who should choose 1KOMMA5°

  • Residential customers, prosumers and small businesses wanting a turnkey hardware plus tariff solution.

  • Partners focusing on residential/prosumer segments and comfortable aligning with a single brand ecosystem.

  • Organisations not trying to build a platform business around EMS + VPP and not prioritising multi-TSO portfolio operations across large assets.

STRATEGIC POSITIONING ANGLE

1KOMMA5° is a strong consumer-facing solution provider for residential and small-business energy kits and fleet aggregation under its own brand. Fusebox system is the neutral EMS + VPP operational backbone for organisations that want to run flexibility as a scalable business across C&I and larger portfolios: multi-tenant and white-label capable, hardware-agnostic, designed to integrate into existing trading and enterprise systems, and built to keep commercial control and vendor choice with the customer.
