2. What truly makes a balcony power plant capable of providing emergency power

A Balcony power plant with emergency power function It absolutely requires a means of providing an independent AC power supply. Technically, this is achieved either through an integrated off-grid inverter with a separate AC output or through an automatic emergency power transfer (EPS).

Without these functions, a system shuts down completely for safety reasons in the event of a power outage. Only when the system can establish its own AC network, separate from the mains, is it technically correct to speak of a true system. emergency power or Emergency power supply.

3. Suitable systems for a Balcony power plant with emergency power function
