What is an emergency power supply
Emergency power or backup power - the reliable supply for the family home
Self-consumption systems, i.e. photovoltaic systems with integrated battery storage systems, can supply important consumers in the event of a power failure. Many inverter manufacturers offer an emergency power or backup power function in combination with selected batteries. This enables the homeowner to have increased security of supply for his own home. We have put together a current overview of our systems with emergency power and backup power as well as the ideal combinations of the manufacturers for you.
Protect against the next power failure with emergency and backup power
In 2017 every consumer in Germany had to have one average power interruption of 15.14 minutes accept. That doesn't sound like much at first. However, a Power failure depending on the region, from a slight flickering of the light to a blackout lasting for days. “The main reason for the increase in supply interruptions at medium and low voltage levels is the increase extreme weather events. The energy transition and the increasing proportion of decentralized generation capacity continue to have no negative effects on the quality of supply, ”explains the Vice President of the Federal Network Agency, Peter Franke.
At the latest when a storm hits Germany and the power fails, the following question arises. Why is the house not being supplied with electricity when the electricity storage is in the basement and is almost fully charged?
Certainly, as with many of our customers, the Memodo power storage comparison is ready to hand at your desk. Does it represent a helpful tool for the subject of photovoltaic systems with battery storage systems due to its extensive and detailed information. It contains our current portfolio of tried and tested combinations of electricity storage systems and the associated system technology. Special functions likeEmergency power and backup power are of course listed separately and clearly.
But what exactly is behind the terms emergency power and backup power and which application makes the most sense for the requirement?

What is emergency power?
As Emergency power is the term used to describe the property of a storage system to provide energy via a separate connection in the event of a power failure. Here usually takes place no automatic switchover of all consumer circuits. Besides, this is here available power mostly limited and up 1-phase consumptionr limited. These usually also need to be manually be plugged into the emergency power supply. Additional complex components are not required here. Depending on the manufacturer, the photovoltaic system can also recharge the battery storage in the event of a power failure.
What is backup power?
Storage systems with Backup power are able to independently switch all consumers to the in-house battery storage system in the event of a public grid failure. Depending on the structure of the system, the 1 or 3-phase battery backup grid. The switching devices required for this require something more installation effort, however, the switching process takes place in the event of a power failure automatically. After switching, it takes approx. 5-20 seconds until all consumers are supplied again. An uninterruptible power supply (UPS) is therefore not available. Depending on the manufacturer, the photovoltaic system can also recharge the battery storage after switching.
