Who Is the Dyness Battery Best For?
The Dyness (PowerBox) battery may suit homeowners who are primarily focused on price and want a scalable battery option that works with a wide range of inverters. It’s best for:
- Budget-focused households comfortable with a newer brand
- Properties needing 9 to 45 kWh of storage with outdoor-rated flexibility
- Installers or buyers familiar with brands like Sungrow, Victron, or GoodWe
However, it’s not ideal for homeowners prioritizing strong brand trust, polished app experiences, or long-term support confidence. If those matter more to you, it’s worth considering better-supported alternatives.
About Dyness
Dyness is a China-based energy storage manufacturer with a growing international presence, including several Clean Energy Council–approved models sold in Australia. While often marketed locally under the PowerBox name, the underlying technology and manufacturing come from Dyness itself.
Founded in 2017, Dyness claims more than 300,000 systems installed globally and operates across over 100 countries. Their focus is on affordable lithium iron phosphate (LFP) battery systems for residential and small commercial use, supported by a 150+ person R&D team and a portfolio of international safety certifications.
In Australia, Dyness batteries are distributed by OSW, with local contact details provided for after-sales support. However, brand visibility remains limited, and long-term reliability is still being established in the local market.

Support & Warranty
The Dyness (PowerBox) battery comes with a 10-year warranty, which is now standard for most residential batteries in Australia. Cycle life is rated at 6,000+ cycles at 80% depth of discharge, which suggests solid long-term durability on paper.
In Australia, local support is provided by OSW (One Stop Warehouse), Dyness’s authorised distributor. Contact details for after-sales service are included in the datasheet, and there is a local support number and email address.
However, as of mid-2025:
- The warranty claim process is not clearly outlined for end users
- Service network availability and response times remain unclear
- App updates and technical support are available but may require installer involvement
This makes support one of the weaker areas for Dyness compared to better-established brands like Tesla, BYD, or Sungrow, which have formal service channels and higher brand trust locally.
