SonnenBatterie Eco 8 vs Tesla Powerwall

German solar company sonnen have been in the news quite a lot recently – they’ve gained 13% of the Australian solar battery market since entering it in 2016 – selling over 11,000 battery units. One of their best selling solar batteries is the SonnenBatterie Eco 8.2 – we’re going to take a look at it today and see how it stacks up against the more popular offerings like the Powerwall 2. Sonnen have sold over 10,000 of these units and have 75% of the market in Germany – the Eco 8 is the eighth iteration of a supremely powerful and mature battery. Let’s learn more:

It’s not suitable for outdoor use (only IP21 rated) and wasn’t previously off-grid compatible, but the Sonnen Eco is now available with automatic blackout/backup power option (sonnenProtect 1300). IT has a 1.3kW total load limit so it won’t run your reverse cycle air con and dishwasher, but is suitable for less intensive appliances like energy efficient fridges, lamps, laptops, fans, chargers, and so on.  It was crazy that sonnen thought it was okay to release a premium solar storage battery without this option, but I digress…click here to read the sonnenProtect 1300 Specifications and datasheet.

Here are some of the of the sonnen Eco specifications:

  • 2-16kWh capacity (modular design which increases in 2kWh increments).
  • Easy to retrofit to your existing panels.
  • Compatible with all panels.
  • 10year / 10,000 cycle warranty.
  • 2.5 cycles per day (2.5x ‘value’ and faster payback).
  • Inverter included.
  • Online management with ‘self learning algorithm’ (automatically decides the best times to charge and supply).
  • Proper UPS and automatic blackout protection with SonnenBatterie Protect 1300.
  • Reliable supplier who has been making these batteries since 2008.

SonnenBatterie vs Tesla Powerwall

This is a real battle of the premium energy storage giants – you can certainly get systems for less but if you want the best it’s Powerwall vs. SonnenBatterie.

The Powerwall 2 and the SonnenBatterie eco are both ‘fully integrated’ systems – which means the unit included inverter, all the power components, and software. They’re both AC coupled – so you’re able to connect microinverters or string inverters to either of them if you so desire.

As mentioned previously, the Eco is only for indoor installation but the Powerwall can be installed outside.

They both have 10 year warranties but the Eco 8 is also covered for 10k cycles – the Powerwall, by comparison, only offers 3,650 cycles.

The Sonnen Eco comes in 8 different sizes, but the comparable model to the Powerwall (14kWh) is currently a little more expensive than the Powerwall. How much, it depends on who you talk to – but if you’re interested in getting a quote then look below:
