This is a hands-on technical role for someone who takes ownership of problems and sees them through to resolution. You won’t just log tickets—you’ll diagnose, fix, and follow issues end-to-end.
You’ll sit at the centre of operations, bridging installation teams, customers, and manufacturers. The right hire here prevents delays, protects reputation, and keeps systems performing as they should.
Key Responsibilities:
*Diagnose and resolve faults across solar PV and battery systems
*Provide technical support for systems including Sunsynk, Hanchu, Tesla (Powerwall), and Sigenergy
*Investigate underperformance, faults, communication issues, and system errors
*Liaise directly with manufacturers to escalate and resolve technical issues
*Remotely access systems where possible to diagnose and resolve faults
*Attend customer properties when required to troubleshoot and recommission systems
*Support installation teams with technical queries and commissioning issues
*Interpret system data, logs, and monitoring platforms to identify problems
*Ensure systems are operating safely, efficiently, and within design parameters
*Manage and prioritise support tickets to meet response and resolution targets
*Provide clear updates to customers in plain English (not technical waffle)
*Assist with warranty claims and technical documentation
The ideal candidate will have:
*Strong understanding of solar PV systems, battery storage, and inverter operation
*Hands-on experience with installation, commissioning, or fault finding
*Solid knowledge of system components: inverters, batteries, optimisers, monitoring platforms
*Ability to diagnose electrical and communication faults (AC/DC side)
*Comfortable speaking directly with manufacturers and pushing for resolutions
*Ability to work independently and take ownership of problems
*Good customer communication — calm under pressure, no fluff
*Competent with apps, portals, and remote monitoring systems
