Full yearly energy flow — the export gap is the opportunity
Key observation: March through August each produce over 2,000 kWh/month, yet 60–68% is exported to the grid. Your 10 kWh battery fills quickly, leaving enormous surplus untapped. Winter months (Nov–Feb) see grid independence drop to 30–60%, with import dependency up to 27 kWh/day.
Monthly Export vs Self-Use Rate
How much of what you produce actually stays home
Daily Average: Produced vs Exported vs Imported
Per-day averages reveal seasonal extremes
May–August: Average daily export of 45–54 kWh while house consumes only ~25 kWh/day. You're producing twice your consumption and sending half to the grid for minimal return. This is the energy a V2H car + Victron system would capture.

How many days you were effectively off-grid each month
Battery Throughput — Charged vs Discharged
Total kWh flowing through the 10 kWh batteries each month (not cycle count)
May–August avg GI: 92–96% — you're nearly grid-free in peak season, but only because consumption is modest. Batteries charge and discharge at near-full cycles daily. Adding storage would extend this to include more of the evening and next morning.

Monthly V2H Potential — With Victron
65% capture rate · Victron static battery (~25–30 kWh) bridges daytime surplus to evening V2H use
Monthly V2H Potential — Without Victron
Car + existing 10 kWh Enphase only · daytime surplus when car is away goes straight to grid
Victron adds 3,006 kWh/year of captured energy vs. V2H alone (4,883 kWh with vs. 1,877 kWh without). The Victron static battery acts as a daytime buffer: it absorbs peak solar surplus while the car is at work, then the car draws from it in the evening. Recommended size: 25–30 kWh LiFePO4 (covers peak May demand of ~25 kWh/day). A 20 kWh battery covers ~80% of surplus days at lower cost.
March–September: 4,006 kWh of exported energy could feed V2H overnight use after commute costs. At ~0.25€/kWh avoided grid price, that's ~1,000€/year in additional value on top of existing savings. Your 60km daily commute needs only 11 kWh — the car battery covers this 277% over from solar alone.

Daily Grid Independence Distribution
How many days achieved each independence level
Feed-in rate varies massively: July earned 5.3 €ct/kWh while May only 1.8 €ct/kWh — confirming Energy Revolt uses a dynamic/spot-based tariff. On average just 3.7 €ct/kWh for 11,123 kWh exported. The same energy avoiding grid purchases at 25 €ct/kWh would be worth 7× more. This is the single strongest argument for V2H storage.
2,372 € total value in 2025 — 1,958 € from self-consumption savings + 413 € feed-in revenue (Energy Revolt). Of 365 days, over 180 achieved >90% grid independence. Crucially, 11,123 kWh exported earned only 413 € (avg. 3.7 €ct/kWh) — the same energy in a V2H car would avoid grid purchases at ~25 €ct/kWh, worth ~2,800 € instead.
Import vs Export by Month — The Seasonal Asymmetry
Summer surplus vs winter deficit — the case for larger storage or dynamic tariffs
Nov–Feb: Total import of 1,772 kWh, yet these same months still export 755 kWh on sunny days. A Victron + 30 kWh static storage (or V2H EV charging overnight at off-peak tariff) would cover most of this gap. Dynamic tariff (e.g. Tibber) would allow charging at ~0.08€/kWh vs peak 0.25€/kWh — saving an additional ~300€/year on winter imports.
