System Design & Sizing
Engineering-grade sizing and system design: load-profile analysis, use-case modeling, product selection across the Navvion family — the Navvion Alpha (257 kWh) and Navvion Beta (261 kWh) C&I cabinets, the Navvion Delta utility block (3.3 MWh), the Navvion Gamma utility block (5 MWh), the Navvion Omega hybrid inverter series, and Navvion Zero — and an integration concept your installer or EPC can build from, with every assumption stated.
What's Included
Designed from your data.
Load-profile analysis
Interval-data analysis of your actual consumption — peaks, seasonality, and how your load coincides with tariff windows.
Use-case modeling
Demand-charge management, backup, solar shifting, and grid services modeled individually and stacked, so you see what each one is worth.
Product selection & sizing
Capacity, power, and product configuration chosen from measured data, with headroom and degradation assumptions stated explicitly.
Integration concept
A single-line concept, interconnection approach, and communication architecture for the recommended configuration.
Process
From load data to buildable design.
Data intake
You provide utility bills or interval data, site documentation, and any existing solar or generation details.
Load analysis
We build your load profile: peaks, base load, seasonality, and tariff exposure — the numbers every later decision rests on.
Scenario modeling
Candidate configurations are modeled against your use cases, with sensitivity analysis on the assumptions that actually move the result.
Design review
We walk your team through the recommendation and the alternatives we rejected, and fold your operational constraints back in.
Design package
You receive the final sizing report and integration concept — ready for proposals, permitting input, and detailed engineering.
A package the next team can build from.

FAQ
Common questions.
What if we don't have interval data?
We can start from monthly bills and a site walkthrough; the design simply carries wider margins until better data arrives. In many cases temporary metering can close the gap.
Do you only design around Navvion products?
The load and tariff analysis is product-neutral — your meter data doesn't care about vendors. The recommended configuration uses Navvion hardware, and we say so plainly; the analysis is yours either way.
Can you review a design we already have?
Yes. Second-opinion reviews of third-party proposals are a common engagement — you get the same analysis, applied to someone else's design.
How do you handle backup requirements?
Backup is sized from the loads you designate as critical and the autonomy you require — not from the whole facility. The report separates backup capacity from economic-optimization capacity so the trade-off is visible.
Is the design package accepted for permitting?
The package is prepared as engineering input for your EPC or installer of record. Stamped drawings are produced during detailed engineering, using our package as the basis.
How does battery degradation factor into the sizing?
Degradation and warranty capacity are modeled over the design life, so year-15 performance still meets the use case — not just day one. The report states the degradation assumptions it relied on.
Can you size for future load growth or EV charging?
Yes. Headroom for load growth or planned EV charging is an explicit input, and the report separates day-one sizing from the growth headroom so you can see what each one costs.
