As an idea, hybrid systems are the most advanced and include all the best of ON-Grid and OFF-Grid systems.
Such systems can act as an ON-Grid, supplying surplus electricity to the grid, if there is an appropriate tariff, can accumulate energy in batteries, both for later use, and as a backup in case of an accident in the network. Such systems can be finely adjusted to the needs of the consumer, depending on the specific situation. In some countries, for example, the tariff at which networks buy electricity depends on the time of day, in that case the customer can set up the inverter so that the energy stored in the batteries can be sold at the most high tariff.
Ideally, based on hybrid systems, can be implemented the Smart Grid concept, where each consumer can act as an energy seller and sell it at an on-line price. In this case, the grid will be invulnerable, since energy is not generated centrally but distributed. Very difficult to say what is the disadvantage of hybrid systems. Perhaps, only relative high cost and the obligation of periodic replacement of batteries.
In our opinion, the development of new types of batteries will make these systems the most popular in the world.
Equipment for hybrid systems are:
- Solar panels
- Hybrid inverter with integrated charge controller
- Rechargeable batteries
- Bidirectional counter.
