Electricity storage for photovoltaic systems is becoming increasingly popular in our country. There are several reasons for this. The first and most important is to avoid power outages caused by failures in power plants. The second reason is to reduce the amount of electricity delivered to the grid, which leads to a more efficient use of our own electricity. Another reason is that the building is located far from the nearest transformer station, and connecting to the grid is far less cost-efficient than investing in photovoltaics. Another aspect that will become increasingly important is the popularisation of energy storage by the utilities themselves and the government in order to be able to use the surplus production of photovoltaic systems more efficiently during the spring and summer months.
Operating a system with its own electricity storage (off-grid type) is very similar to grid-connected photovoltaics. That is, a system in which the surplus electricity is fed into the utility grid. The difference is that through the use of batteries and hybrid inverters, the surplus electricity generated flows into the batteries. However, the energy from the batteries can be drawn in the evening, for example, and when there are no more energy reserves in our energy storage, the energy is only then drawn from the grid. To fully monitor the operation of the entire system, it is necessary to use the SolarEdge Modbus meter. Read more about this device here!
In our range of photovoltaic systems with electricity storage, we also have systems from Peimar in addition to the StorEdge solutions from SolarEdge. The system consists of photovoltaic modules, hybrid inverters, special optimisers and batteries. All these components are manufactured by Peimar in Italy.
As with the SolarEdge solution, Peimar has developed specific solutions that best meet the independence and self-consumption requirements of domestic installations.
The devices developed by Italian engineers are characterised by a long service life and very high quality. By adding power optimisers to the hybrid inverters and batteries, he can increase the efficiency of his autonomous photovoltaic plant.
Peimar also has a dedicated application for monitoring the operation of the photovoltaic plant, so that we can keep an eye on the impact of our power plant and react to possible unfavourable situations.
We can choose between single-phase and three-phase hybrid inverters. The available power range is from 3 kW to 10 kW.
