Installation and configuration of a photovoltaic self consumption system with batteries

2 System description and strategy

A self-consumption installation is a system connected to the grid that seeks to minimize grid
consumption and increase self-supply. To do so, it is fitted with photovoltaic generation and
storage components.
Photovoltaic self consumption installations with batteries managed by the INGECON SUN EMS
Board offer a greater range of possibilities for a more efficient management.
An additional Back-up function can be activated in this type of installation. With this function, in
the event of a power cut, only the ISS 1Play inverter disconnects the grid and feeds energy
required for critical loads from the batteries, operating in a similar manner to a UPS. The IS
1Play photovoltaic inverter is disconnected to the grid and it doesn't supply energy. The non-
critical loads are not fed.
The evolution of the battery charge status will depend on the energy generated by renewable
sources, on the consumption demand of the installation and on configuration of the energy
manager's strategy.
Below is an example of energy management in a photovoltaic self consumption installation with
batteries.
Consumption of the installation
In this example the EMS Board establishes the photovoltaic production settings to supply
instantaneous consumption and the battery charging process.
When the batteries are charged, photovoltaic generation is in line with consumption.
At night-time, the storage allows you to cover the installation demand, minimizing consumption
from the electrical grid.
