* 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
