never pay an electricity bill again: smart battery lets you use solar energy at night - lithium iron battery

Over the past year, solar power generation in the UK has more than doubled, while solar power generation in the US has increased by 30.
However, many current systems cannot solve the problem of how to manage and use energy overnight when the sun sets.
Traditionally, the energy collected during the day is sent back to the grid, but it can be expensive if you need to buy it back
Unless you have a smart battery at home that stores excess energy.
With this in mind, the automatic storage devices of German companies (ASD)
And the design of tungsten sonnspeicher Walter has been established.
It uses lithium-ion batteries to store energy collected during the day by solar panels mounted on the roof.
This energy is used throughout the day and any excess energy is stored when the sun goes down.
Homeowners can use this stored power to power their home until the sun rises again rather than selling excess power to the grid and may have to buy it back at a later date or time.
Sonnspeicherfeatures has an intelligent management system that automatically controls charging and discharge current, making it easier to manage how much energy is used.
In addition, it also has sleep mode, ensuring that the storage system never runs low, and automatically goes to standby when it is not used to improve efficiency.
Although it is designed to be completely independent of the state grid, it can also be connected in an emergency.
For example, whenever there is energy available in the battery, the connection to the grid is locked.
When this energy runs out, Sonnenspeicher connects to the grid "per second.
This switch also works in another way.
If a home is mainly powered by a power grid, Sonnenspeicher will still store energy and instead act as a generator when power is cut off.
"We want to create a storage system that will allow you to truly be independent of the State Grid, to provide adequate supply to all your home appliances at any time, and to remain efficient and cumbersome --
The company says at least 20 years are free so you can rest assured that your investment is really worth every penny.
The system has different sizes, from sonnspeicher 300, which is 4.
8 KW, to sonnspeicher 600 at 8.
06 KW hours to provide 1000 models of 13. 44 kWh.
Starting at 450 euros (£6,170).
The company says ordinary families can save about 1,200 euros a year (£876)
Therefore, it will still take about seven years to recover the cost, but the system will last for 20 years.
