1. Useable capacity of 10kWh with a warranty of 10 years

2. An IP56 outdoor rating, meaning it can withstand harsh weather conditions outside.

3. A built-in smart management system to help optimize it for longevity and safety.

4. 5kW continuous and 7kW surge backup power capacity in case of grid outages.

5. Lithium Iron Phosphate cell chemistry

Sonnen Vs Tesla

Comparing two of the leading solar energy storage systems, Sonnen and Tesla Powerwall 2. Both battery systems have their advantages and disadvantages depending on the homeowner’s needs.

Here are four key points to consider when comparing Sonnen vs Tesla:

* Pricing comparison. Sonnen is cheaper than Tesla Powerwall 2 but both batteries have similar performance.

* Technology differences. Sonnen uses Lithium Iron Phosphate (LFP) while Tesla still uses Cobalt in their batteries.

* Stackable capacity: Tesla Powerwall 2 can stack for increased storage capacity.

* Warranty coverage: Sonnen has a 10-year warranty and 10,000 charge cycles at 80% compared to 70% retention capacity with the Tesla Powerwall 2.

Both batteries have their own strengths that depend on individual consumer needs. Also both batteries would be great in case of a grid outage.

Sonnen Vs other Solar Batteries

The Sonnen and Tesla batteries are two of the most popular home energy storage solutions on the market. But how does Sonnen compare to other batteries?

It is important to look at factors such as safety, cost, efficiency, lifecycle and environmental impact.

LFP cells are non-flammable and much safer than Lithium Nickel-Manganese-cobalt (NMC).

They also have a longer lifespan of 15-20 years and guarantee 80% outrput.

Additionally, LFP cells do not contain toxic heavy metals and are environmentally friendlier.

With a 10,000 charge cycle guarantee they are much more cost effective than their counterparts on the market.

Ultimately, these features show why Sonnen has become the preferred choice for home energy storage across Australia and around the world.
