Tesla is the main player in the home battery market

Pros:

• Available in EU
• There are those. support
• Proven technology
• Surge Protection

Weaknesses:

• Price
• The lack of the ability to connect peripherals out of the box to store energy, for example, from solar panels
• Requires a room with active cooling
• No peripherals included

Tesla Powerwall

Tesla has prepared two versions of the Powerwall: one — with a capacity of 10 kW and a cost of 3.5 thousand US dollars, and the second — with a capacity of 7 kW and a cost of 3 thousand dollars. Its dimensions are about a meter in length and width, with a thickness of about eighteen centimeters. Powerwall comes with a home heating control support system. It is also possible to control it via the global network. The battery is recharged both from a solar battery or a wind generator (if any), and from an ordinary source of electricity.

Pros:

• Price
• Easy to install
• It is possible to connect alternative sources
• Design
• Out of the box cloud

Weaknesses:

• No direct delivery 
• No statistics on battery degradation
• No peripherals included and limited selection
• Does not work well with non-standard peripherals

Aquion Energy S20P

The Aquion Energy S20P Modular Battery is a battery pack for energy storage systems. If required, 12 batteries can be connected in series to form a powerful M100 - LS82P. Based on safe, clean and sustainable hybrid Lithium Ion technologyogie. The S20P modular battery is perfect for powering small devices that do not require constant power. Thanks to the fast charging system, the battery is able to quickly restore the spent charge.

Pros

• Price
• Modular design
• Fast charging
• Available with delivery f.

Disadvantages

• Small capacity for its price

Iron Edison 24V Lithium Battery

Iron Edisson develops Lithium Ion Battery Systems. They work great with both solar panels and conventional grids. The standout feature is that the system works perfectly with inverters and charging stations from Outback, Schneider Electric, Magnum, SMA and MidNite Solar, making installation easy.

Pros:

• Large choice
• Integration with major peripheral brands

Weaknesses:

• No direct deliveries to .
• Appearance
• Price

Chinese batteries for the home. DIY

It's fair to say that building your own Lithium-Ion battery is fairly easy these days. Chinese online stores present a large selection of batteries of various capacities. With minimal engineering skills, low-power devices can be assembled to power a 5-12 volt network. (for example, backup power for routers, network drives and other computer equipment. You can power infrared floor heating, heaters for pipes and wells in the country, various ice lights - the so-called standby lighting) If we want to assemble a battery to power devices with a standard voltage of 220 -230 volts, need other batteries. It will not be superfluous to take care of additional protection against overheating and overcharging. Then the price of the finished device may be comparable to that offered on the market, or even more considering the current exchange rate.

Conclusions:

Having considered all the possible options, you can come to the choice that at the beginning of 2016 there were no worthy alternatives to Tesla batteries. This is primarily due to the cost of production of batteries. And until a new cheap technology for production appears, talking about an electric revolution is at least a prelude.
