Executive Summary

An EV battery holds enough energy to power a typical home for 3-10 days. V2H technology unlocks this resilience, making the EV the ultimate survival tool.

The Ultimate Powerwall

A Tesla Powerwall holds 13.5 kWh. A Ford F-150 Lightning holds 131 kWh—equivalent to 10 Powerwalls. V2H allows bi-directional current flow, letting you island your home during a blackout. This turns the EV into a massive asset for climate resilience in an era of unstable grids.

Hardware Requirements

V2H requires a special bi-directional charger and a gateway to isolate the home from the grid (safety requirement). Companies like Enphase and SolarEdge are integrating EV charging directly into solar inverters to make this seamless. The "Whole Home Energy" ecosystem is the new battleground.

Grid Independence

Combined with solar, V2H allows for near-total grid independence. You charge on solar during the day and run the house off the car at night. EV.NET tracks the complex interoperability between different car brands and home energy gateways.

Strategic Opportunity

Own the Digital Infrastructure

As the market for V2H matures, authoritative digital real estate becomes scarce. EV.NET is the category-defining asset for this sector.
