Technical Support Engineer

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
