A hybrid inverter is an "expanded" photovoltaic inverter that converts direct current into alternating current and manages and coordinates electricity flows from the photovoltaic, battery and national network.

Figure 1

The hybrid inverter "decides" whether to send electricity directly to the user for immediate consumption,

 Figure 2

or whether to store it in the battery,

Figure 3

or release it on the national network when the battery is fully charged.

Figure 4

In the same way, it manages the energy coming from the battery or the grid towards the households.

The hybrid inverter can be installed on a photovoltaic system with a storage battery,

Figure 5

or on a photovoltaic system without a battery.

Figure 6

To Install a hybrid inverter allows preparing the system for the addition of a storage system. This avoids having to add the coupling inverter to the traditional inverter for battery management,

Figure 7

and save both on the total cost and the complexity of the system.

Flow of operation

During daylight hours, users consume the energy produced by the photovoltaic system (see also The fundamental basis for the knowledge of a photovoltaic system

Figure 8

while the excess production is accumulated in the battery, if present.

Figure 9

When the battery is fully charged, the excess energy produced is fed into the national network,

Figure 10

when the modules stop producing energy, for example in the evening, the inverter triggers the battery, which powers the equipment at home.

Figure 11

In the event that the energy stored in the battery is completely used, the inverter automatically triggers the withdrawal from the national network.

Advantages of the hybrid inverter

•  Have complete control of the photovoltaic system, and of the storage system. Guided management of production, battery use, and the introduction of unused energy into the grid.
• Thanks to the management and monitoring software, including wi-fi, customized based on the client's request, such as maximizing self-consumption.
• The photovoltaic system is already prepared for the installation of storage batteries, if not present.
• Economic savings, reduced dimensions, and the possibility of functioning as EPS (anti-black-out).
• Management of the photovoltaic system with different orders of priority. For more details click here
  

Recommendations

1. the electrical voltage produced at the inverter output is of dangerous value (230Volt), and therefore all electrical connections MUST BE carried out by expert and qualified persons.
2. In general, the direct current (DC) is on average dangerous and depends on the absorption time, from 40 to 500 mA; and it is ALWAYS DANGEROUS if it exceeds 500 mA.
3. For alternating current (AC), the danger value is lowered ten times: it depends on the absorption time from 10 to 50 mA, and it is ALWAYS DANGEROUS when it exceeds 50 mA. FOR WHICH ALWAYS BE VERY CAREFUL.
