Storing the electricity in a battery
Thanks to an off-grid system independence from the public grid is possible. The principle is simple: electricity is being generated in a sustainable way through solar panels or wind power. An intelligent controller determines whether the electric current goes directly to the consumer or is stored in a battery. In this way electricity is also available at times when there is no sun or wind. This is an ideal solution e.g. in remote areas that have no access to the public grid or for events in open air.
Batteries and controller
The battery and the controller are two important components. The controller is the core of your installation. If there is a sudden need for electricity, the controller will steer the generated energy directly to the consumers post (e.g. a lamp). If, at the time of electricity generation, there is no demand for energy, the electricity is automatically stored in the batteries. A battery has the size of an inverter, but its storage capacity is calculated in function of the required consumption. A battery can vary from 2 kilowatt hour (an electric heater) to 5 kilowatt hour. Therefore it is important that the system is correctly sized and configured.
The estimated lifetime of a battery is between 4 and 5 years, as it runs with a capacity between 4.000 to 5.000 cycles. A cycle is the charging and discharging of the battery.
How does it work?
As soon as the electricity production exceeds the consumption, the excess electricity is stored in a battery. Thanks to the inverter the DC of the battery can be converted into operable AC to be used by the different consumers (electric appliances). The core of the system is the controller that determines whether the current is being distributed to the consumers or stored in the batteries. Our solutions are equipped with intelligent controllers which take care of an optimal charging and discharging of the batteries. This is of paramount importance for the durability of the batteries.
Ideal for remote areas
Ideal for remote areas, far away from the grid, like a holiday park deep in the forests or a one-off festival in open air, just to name a few examples.
