FAQs - Energy Storage System

The Energy Storage System is an intelligent, state-of-the-art storage system for solar or biogas electricity, tailored to the private household or "small" business. The operator of a photovoltaic system can use it to effortlessly store the solar power he generates himself, so that he can then consume it himself at any time of the day.

You significantly increase your own consumption! Self-consumption is the own consumption of the self-produced solar power. Already today, this mode of operation of a Solar-PV System is, from an economic point of view alone, clearly superior to the so far widespread feed-in of electricity. And this economic advantage grows with every electricity price increase of your energy supplier.

An intelligent solar power plant is a complete and high quality solar-PV power plant, which is coupled with the energy storage system. Thereby it is achieved that self-produced solar power can be consumed not only when the sun shines, but also when it is needed or consumed. Thus, for example, own solar power can also be consumed at night! The solar power plant is offered as a complete system including all services and turnkey by us on request. You can contact us on +49 (0) 52 51 - 142 09 23 or email us at info@esl-emobility.com

The more of your own electricity consumption you can cover with your self-generated solar power, the more independent you become from your electricity supplier. And the less you have to care about the annual price increase or where the electricity of your supplier comes from.

With the significant increase in self-consumption provided by your energy storage system, you will always know exactly where the electricity you generate yourself comes from. Namely from your own roof from the sun's eco-energy. Thus, you do not consume limited fossil raw materials, do not emit any CO2, do not generate long-term radioactive waste. Furthermore, you stabilize the capacity of the power grid. In short: You make your own personal contribution to the energy transition!

For all homeowners who want to significantly increase the share of self-generated solar power in their own electricity consumption. And this even if no one is at home during the day when the sun is shining. Whether for economic reasons, the need for maximum independence from electricity suppliers and their pricing strategies, or the desire to preserve our planet for our children.

No, absolutely not. The exclusively used, modern lithium batteries have been developed for the particularly demanding mobile sector. They have been positively tested in their behaviour even in crash and fire. Since neither lead nor acids are used, no gases can escape from the system either. Overcharging or undercharging of each individual cell is also ruled out by the battery management system.

According to the manufacturer, the batteries are designed for a service life of up to 20 years. This is achieved by the control system being very careful with the battery, i.e. by not reaching the limits of performance and capacity. For example, only approx. 10% of the maximum possible current is consumed or released when the battery is charged and discharged. In addition, only a maximum of approx. 70% of the battery's storage capacity is charged and used.

Of course, defects (e.g. due to manufacturing or material defects) can also occur with batteries. Therefore, every customer receives the long-term product and performance guarantees of the manufacturers on the useful capacity of his storage. After expiration of this warranty, it is possible to purchase individual cells for replacement purposes from ESL E-MOBILITY instead of the entire battery system.

To determine the optimal size with a reasonable cost/benefit ratio, both the annual electricity consumption and your individual times of day and quantities of electricity consumption are decisive. Our expert advisors will be happy to assist you in selecting the right energy storage for you. Call us on +49 (0) 52 51 - 142 09 23

As soon as the power from the energy supplier fails, the energy storage takes over the supply of your house. Depending on the state of charge of the battery, the capacity of the storage unit and the consumer devices that are switched on, the energy storage unit supplies power.
