Optimising home installation systems
Relevant for property owners
How can households protect themselves against power outages?
Domestic electrical installations, solar panels, battery storage – homeowners and tenants have various options for preparing for a power cut.
Although power cuts are usually brief, they can sometimes last longer in individual cases.
There are various ways of doing this:
Please note:
Changes to the house installation should never be carried out by yourself, but only by a qualified electrical contractor.

Optimising your house installation
As a property owner, you can have the electrical installation in your property adapted by a specialist firm so that you remain connected to the mains for at least a certain period of time during a power cut.
You can have the appliances in your home that you really need urgently connected to a single phase: the electric lighting, the fridge, the roller shutters or the Wi-Fi router.
Note on emergency power supply
If only a single-phase emergency power supply is available, the most essential electrical appliances in your home will still be powered, and you will not need to leave your home permanently.
Note on existing and new-build properties
In an existing building, this conversion is complex and costly. These recommendations can be easily implemented in new-build properties or where modernisation is planned.

Off-grid operation with a solar PV system or emergency power supply
If, as a tenant or homeowner, you combine your solar PV system with a battery storage unit fitted with an off-grid-capable inverter, you will have your own emergency power supply to which you can connect the most essential appliances in your home. The alternative is a diesel or petrol-powered generator.
Please note:
For both models, your domestic electrical installation must be prepared appropriately. The supply from the mains and the emergency power supply must never be active at the same time. This requires careful preparation and implementation.

A useful tip:
You can also use your electric car’s battery as a power storage solution. You can use the electricity from the battery to supply your home with power from time to time (Vehicle-to-Home), thereby increasing the resilience of your energy supply.
Balcony power station – an option for tenants
Even if you live in a rented flat, you can take active steps to prepare for a power cut with relatively little effort. Do you have the option of installing a balcony solar panel? If you combine this with a battery storage unit featuring a built-in socket, you’ll have your own electricity – at least for a short while – to charge your mobile phone, for example.
Please note:
As a tenant, you have fewer options than a homeowner. Any modifications to the electrical installation in your flat must be arranged by your landlord and carried out by a qualified electrical contractor.
