V2G vs V2H vs V2L: what the differences mean for a property
The three acronyms describe where the power goes. That single difference changes the hardware you buy, the approvals you need and the money the system can make.
| V2L | V2H | V2G | |
|---|---|---|---|
| Power flows to | Appliances and tools | The building, behind the meter | The utility, across the meter |
| Site equipment | None — a socket or adapter | Approved inverter and transfer switch | Bidirectional charging equipment and controls |
| Approvals | None | Electrical permit and inspection | Permit plus a utility interconnection agreement |
| Earns revenue | No | Indirectly, by avoiding outage losses | Yes, plus demand and energy savings |
| Typical scale | A few kW | A building or a loop | Site-wide, aggregated into MW |
How they stack in practice
Most properties end up using more than one. V2L is a guest convenience that costs nothing to allow. V2H is the resilience story: keeping a dock office, camp store, bathhouse or condo lobby alive when the grid drops. V2G is the revenue story, and it is the one that requires the utility to be at the table.
GridLynQ deploys these together. The same bidirectional pedestals and site storage that shave your peak also island critical loads during an outage and export when a programme calls — the value stack is what makes the capital case work.
Which to lead with
- Frequent outages and guest-experience risk: lead with V2H and size storage around critical loads.
- High demand charges on a summer-peaking bill: lead with peak shaving, then add export.
- An active utility or ISO programme in your state: lead with V2G, because the programme revenue changes the payback maths.
