6 knowledge areas for industrial battery storage
We build ZynexGroup’s knowledge base around six core areas. Active pillars contain published articles; planned pillars open as material is ready.
BESS 101
What is industrial battery storage, and why does it matter for your business?
The technical and conceptual foundation pillar. Explains what BESS is, how it works, LFP vs NMC, grid integration, Energinet’s role, and the key concepts.
- Grid connection wait times are historically long, and what that means for those who act now
- What is State of Health (SoH) in an industrial battery - and who is responsible?
- Proactive vs. reactive battery service: Why the difference is measured in production hours
- What is a grid connection, and why is 400A a practical rule of thumb for BESS?
The financial case
How does a battery become an investment with a reliable return?
The CFO’s pillar. ROI, grid capacity as an asset, EIFO financing, trading mechanics, system services, revenue stacking, and what happens after year 6.
Coming soonProduction security
How do you protect production against an unstable power grid?
The COO’s pillar. Energinet forecasts, STS technology, outages, downtime, operating costs, security of supply, and backup logic.
Coming soonPragmatic sustainability
How do you document and communicate real green action?
The ESG and marketing pillar. ESG reporting, CO₂ displacement, renewable integration, greenwashing vs real hardware, and employer branding.
- Pragmatic sustainability with BESS: What you can actually measure, report and communicate
- Scope 2, energy flexibility and BESS: What finance and ESG should align on
- Employer branding: Can BESS be used in recruitment and a green profile?
- How to communicate a BESS investment internally and externally without overclaim
