Energy Security

Blackout Protection and Black Start

For many homeowner security of energy supply is an increasing concern.

The sonnen Evo has a built-in backup capability and can provide emergency power for the home in the case of a grid outage. The switch over to back up power occurs automatically, however there will be a small delay of under a second.

In back up mode the sonnen Evo battery can supply 5kW of continuous power during a black out. The battery is single phase so will only supply emergency power to the phase of the home it is connected to.

The battery has black start capability. During an extended blackout if the battery goes flat, this means you you can start charging the battery from the solar panels during the day when they are producing enough power.

To support black start the solar inverter on the solar array must be on the back up phase and be of 6kW or smaller capacity.
