Would you like to be able to keep your house running for several days – even when electricity is expensive or if the grid goes down? With a solar inverter (approved), a home battery and Sunmate AI control you can get a setup that makes optimal use of your own energy. And when you supplement with V2L from the electric car, you get an additional power source that can significantly extend the operating time.

In this post we show the principle of a comprehensive solution, where the group board is installed above the solar inverter, so that the entire house can be supplied via the inverter – from the internal battery and supplemented with power from the car.

Briefly explained: this is how it all works

The solution functions as an energy hub:

• The solar inverter is the hub that distributes and controls the energy in the house

• The home battery supplies power when the sun is not shining or when you want to use cheap/own power

• Sunmate AI optimizes when to charge/deplete so you get the most out of your energy

• V2L from the electric car can be used as an additional supply when you want to extend the operating time or increase the available power

The important thing is: You use a existing, approved solar inverter as the central part – and our car-to-home solution makes it possible to feed power from the car into the system via the inverter.

Why it makes sense: 3 concrete benefits

1) The entire house can run via the inverter

When the group board is placed above the solar inverter, the house can be supplied as a whole through the inverter. This means that you don't just have power for "a few outlets" - but can keep the house running as a whole (depending on the size and consumption).

2) Several days of operation with battery + V2L

A home battery can provide many hours of operation. When you supplement with V2L power from the car, you can in practice extend it to several days, because the car acts as an additional energy reserve.

3) Intelligent control with Sunmate AI

With Sunmate AI control you can automate and optimize:

• When to charge the battery

• When should the house run on battery power?

• When does it make sense to supplement with V2L?

It provides a solution that not only works in theory - but also in everyday life.

Supplementary emergency power: power station (portable power station) as extra buffer

If you want even more robustness, you can supplement with a power station (portable power station). It acts as an extra buffer that you can use in two smart ways:

• As additional emergency power for selected items (e.g. router, lights, charging, cool box) – independent of the house's installation

• As a mobile power reserve, you can move it wherever you need it (home, workshop, camping, summer house)

In practice, it gives you extra security if you want multiple layers of backup – especially if you want to be able to keep critical things running even when you "spare" the home battery.

How to use V2L in the solution

V2L (Vehicle-to-Load) means that the electric car can deliver 230V. In this overall solution, V2L is used as a supplementary power source, which is fed in via the solar inverter, so that the house can continue to run on the same “power rail” as the battery/solar.

This is especially relevant when:

• You want to increase the operating time during a power outage

• You have high consumption during periods and want to relieve the battery

• You want to use the car's large battery as an extra reserve

What do you need for it to work?

Here is a handy high-level checklist:

• One solar inverter (approved), which can act as a hub for the house's supply

• A home battery to the inverter

• Sunmate AI control for intelligent optimization

• An electric car with V2L (or a solution that can add V2L functionality in selected scenarios)

• Our car-to-home solution, that connects the car to the inverter

• (Optional) Power station (portable power station) as an additional emergency power buffer

If the car does not have V2L from the factory, in selected scenarios you can use an external converter that adds V2L functionality:  https://v2lpower.com/product/v2l-power-5-kw-ekstern-omformer-3/ 

Who is the solution suitable for?

This comprehensive solution is ideal for you who:

• Have solar panels or are considering solar panels?

• Want backup and stable operation in case of outage

• Will utilize battery + AI management to optimize consumption

• Will be able to supplement with V2L from the car for extra operating time

• Want extra security with a power station (portable power station) as a “backup to backup”

FAQ

Can the whole house really run this way?

Yes, when the group board is connected to the solar inverter, the house can be supplied via the inverter. The actual operating time and power depends on the inverter, battery, the car's V2L and your consumption.

Is V2L the same as V2H?

V2L is 230V from the car. When it is fed into the house's system via the inverter, you get a solution that in practice functions as V2H in everyday life.

Can it run for several days?

Yes, in many setups, the combination of home battery + V2L can provide operation for several days – depending on consumption and capacity.

What is the advantage of a power station as additional emergency power?

A power station (portable power station) gives you an extra buffer that is independent of your home's installation. It is especially good for keeping critical things running (internet, lights, charging) and can be moved to where you need power.
