Common Questions
Is Sonnen worth the premium price over BYD or GoodWe?
Sonnen's premium is largely justified by build quality, the integrated energy management platform, and the sonnenCommunity program. For customers who want a set-and-forget system with sophisticated energy management and community energy sharing, it's worth considering. For pure value-per-kWh, BYD or Sungrow offer more competitive pricing.
Does Sonnen work with existing solar?
Yes. The sonnenBatterie can be AC-coupled to most existing solar systems, meaning you typically won't need to replace your existing solar inverter. We'll confirm compatibility during the site assessment.
What is the sonnenCommunity in Australia?
The sonnenCommunity allows sonnen battery owners to share excess energy with other community members and receive credits. Availability and terms in WA vary — we recommend checking with Sonnen directly for current AU program details at the time of your installation.
