Sonnen Core Battery

Sonnen Core Battery

Sonnen (yep, the s is not capitalised) is a German energy company that has been manufacturing commercial batteries for quite some time. They intend to target the household storage segment in the United States with the introduction of the sonnenCore.

The sonnenCore is an all-in-one battery storage system that has a total capacity of 10 kWh. Due to the fact that it is an alternating current (AC)-coupled battery, it is in direct rivalry with the current market leader, the Tesla Powerwall.

The fact that it makes use of lithium iron phosphate (LiFePO4) battery technology, which is both safer and healthier for the environment, is a major selling feature. In comparison to the Powerwall, which employs the more common lithium nickel manganese cobalt chemistry, this gives it a distinct competitive advantage.

The sonnenCore is presently available for purchase for $9,500 before installation. This is a significant savings over their sonnenEco and EcoLinx versions, respectively. However, this places it in second place behind the Powerwall, which has a larger storage capacity and a cheaper total cost of ownership.

This is quite common for solar batteries, as Sonnen provides a 10-year warranty that ensures the battery will retain up to 70% of its storage capacity over the course of the warranty period.

Battery Storage Systems: What To Look For

Battery Storage Systems: What To Look For

Stackability

Lighting, outlets, air conditioning, sump pumps, and other essentials may not be powered by a single battery, so you'll need to make a list of which ones are most important before you go shopping for a new one. Stacking or piggybacking more than one unit may be necessary if you require more than one system to run your entire home.

Differentiating Between Systems That Use An AC And A DC Connection

Electricity stored in batteries and solar panels is called direct current (DC). It is more efficient to use DC-coupled systems to connect solar panels to the grid. Alternating current, or AC, powers both the grid and your house. Even though AC systems are less efficient, they are more adaptable and less time consuming to set up, especially if you already have solar panels on your roof. For new solar installations, the manufacturer can usually provide guidance, but AC is typically utilised with existing solar systems while DC is often used for new solar installations.

Capacity To Begin Loading

To start up some appliances, such as central air conditioning or sump pumps, they demand more power than when they are running. If you have a lot of appliances, make sure the system can handle them all.

Sizing A Battery

Battery sizing is sometimes done on the basis of "one size fits all," however this can lead to subpar performance and a failure to live up to customer expectations. The two most common explanations for this are:

  • Undersized batteries - they don't have enough power to suit the needs of the household.
  • Oversized batteries - The solar array does not have enough power to charge the battery when it is overloaded with large batteries.
An array's size, system type (on- or off-grid), backup power requirements, and most significantly, its evening and overnight energy consumption should all be taken into consideration when choosing a battery to minimise these problems (kWh). It's fortunate that today's battery systems are scalable and flexible so that they may be tailored to suit your needs.

What Type Of Battery Backup System Is Best For Your Specific Needs?

You'll need to figure out how much power and voltage your entire home uses. As a result, Lowe's provides a useful worksheet to help you determine your power requirements. If you know how many watts and volts your appliances require, you'll want to add at least 20% to the total so that your system can keep up if you add electronics or appliances or anything starts drawing more power than usual.

For those who aren't able to afford the retail and installation costs, many places offer some form of payment plan to help you spread out the total expense over time.
