Description
Overview
The Deye SUN-8K-G05-AU is a three-phase, grid-connected PV string inverter delivering 8 kW of rated AC output in full compliance with AS/NZS 4777.2. With 2 independent MPP trackers and a maximum efficiency of 98.2%, it is engineered to maximise energy harvest from commercial and residential solar arrays.
A low 140V start-up voltage and a wide 120-850V MPPT range let the inverter begin generating earlier in the day and adapt to a broad range of string configurations, while zero-export and VSG (Virtual Synchronous Generator) support, optional string-level monitoring and an optional anti-PID function make it a flexible, future-ready choice for the Australian grid.

Product Warranty
What is a warranty? A warranty is a voluntary promise offered by the person or business who sold the product or service to you. Once you buy the product or service, the promise becomes a right that can be enforced under the ACL. Warranties are separate from your automatic consumer guarantees. The consumer guarantees which apply regardless of any warranties suppliers sell or give to you, apply for a reasonable time depending on the nature of the goods or services. This means consumer guarantees may continue to apply after the time period for the warranty has expired.
