Vehicle-to-Home (V2H)The car in the driveway doubles as the home battery
An EV holds several times the energy of a home inverter battery. With a bidirectional charger and a home EMS, it can run the house through a power cut or the evening peak, then refill from rooftop solar.
Vehicle-to-home (V2H) uses an electric vehicle's battery to power a house through a bidirectional charger. The home EMS decides when the car powers the home, for a power cut or the evening peak, and when it recharges, ideally from rooftop solar, always keeping the range the owner needs for the next trip.
Vehicle-to-home (V2H), step by step
- 1
Solar charges the car
Rooftop solar that would be exported cheaply charges the car through the day.
- 2
The car runs the evening
After sunset the car carries the home's load instead of grid power at the peak rate.
- 3
Backup in a power cut
When the grid drops, the house switches to the car: lights, fridge and Wi-Fi stay on.
- 4
Range is protected
The EMS stops at the range the owner set, so the car is ready for tomorrow.
What the Ingro OS does
The same hardware-agnostic layer that runs Ingro EMS sits between the grid and every battery.
Solar first
Puts rooftop solar into the car before exporting it.
Reserve held
Keeps a reserve for outages without giving up the evening savings.
Range kept
Never discharges below the range the owner needs.
Battery cared for
Shallow, gentle cycles so the car's battery lasts.
In India so far
- Today
India already runs on home backup
Millions of homes already have an inverter and battery. As PM Surya Ghar puts solar on 10 million roofs, the question shifts from adding storage to making it smarter, and the EV is the biggest battery a home will own.
What each side gets
Homes with solar and an EV
Evening power from their own solar, and backup without an extra battery bank.
Inverter and charger makers
A home EMS that coordinates solar, inverter, battery and the car.
Installers
One system to set up instead of separate backup and charging.

Aug 2026India Already Has Home Storage. The Next Upgrade Is Inside the Battery
PM Surya Ghar is on track to put rooftop solar on 10 million Indian homes, and the conversation is already shifting from panels to batteries. But India has run on home backup for two decades — the residential storage question was never adoption. It is upgrade.
Sep 2026India Wasted 11 Billion Solar Units in 15 Months. Factories Have the Same Gap
India wasted about 11 billion units of solar in 15 months while running short of power at 8 pm. The same noon-versus-evening mismatch sits inside almost every factory, and storage fixes it with no land, no evacuation approval and no corridor.
Sep 2026Ingro Energy and ISGF Sign MOU for a Unified V2G Operating System
India has proven both V2G modalities in the field: battery swapping (Sheru and BSES Rajdhani, 2023) and AC charging (ISGF-led demo, 2026). Under an MOU with ISGF, Ingro Energy will unify them in one V2G operating system for discoms and OEMs.
Vehicle-to-home (V2H): common questions
3 questions
It depends on the car and the load, but a typical EV battery holds several times the energy of a home inverter battery, enough to carry essential loads for a long outage while keeping range for the next trip.
V2H powers your own home and stays behind your meter. V2G exports to the grid, usually through an aggregator, and is paid for it.
Yes. V2H needs a bidirectional charger and a car that supports exporting power, plus a changeover so the house is isolated from the grid during a cut.
