Our verdict

The Deye RW-M6.1-B is a high-voltage modular LFP battery that pairs with Deye's popular SUN hybrid inverter range. Using 6.1kWh stackable modules, it scales to 24.4kWh for larger homes. Deye has become one of Australia's fastest-growing inverter-battery brands, known for aggressive pricing and a full residential product range. Their Australian entity (Deye Australia) handles local warranty and support.

What we like

Strong value: competitive $/kWh installed pricing
6.1kWh large modules — fewer modules needed for target capacity
Pairs natively with Deye SUN hybrid inverters
Growing Australian installer network and local support
Modular to 24.4kWh for larger homes

What could be better

Deye is newer to Australian market (2020+) — less track record
Designed for use with Deye-branded inverters
Not eligible for the WA Residential Battery Scheme rebate — its Deye inverters are not on the Synergy SSL
Brand reputation still building in Australian market

Who should buy it

Cost-conscious buyers wanting large capacity
Installations pairing with Deye hybrid inverters
Homeowners wanting a value all-in-one solar + battery solution
Larger homes needing 12-24kWh at competitive cost
