AUSTA

About the partnership

AUSTA is the inverter and battery storage brand of Ningbo Austa Solar Tech Co., Ltd., part of the OSDA Group. We use AUSTA's hybrid inverters and LiFePO4 battery storage across our solar and battery installations, chosen for their UK grid-compliance certification and wide power range.

The AUSTA range we fit spans single-phase hybrid inverters from the KESL-G2 series through to the newer KESL-G3 generation, covering outputs from around 3kW up to 10kW, alongside compatible LFP battery storage. Every unit is IP66-rated for outdoor mounting, supports parallel operation and AC coupling for retrofitting onto an existing solar array, and includes anti-backflow protection, dual backup outputs, 2x peak power handling, and cloud-based monitoring.

AUSTA's inverters are independently tested and certified to the UK's G98, G99 and G100 grid-connection requirements, plus the international IEC 61683, IEC 61727, IEC 62116, IEC 62109-1/-2 and EN 50549 safety and EMC standards — the certification our team checks before any inverter goes on a customer's wall.

Every AUSTA inverter we install is covered by the manufacturer's standard warranty, with full terms and specifications set out in the documents below.
