About Fexey
Built by doing.
Ready for scale.
Fexey Pty Ltd is the company behind the Sync Energy journey. Since 2017, our teams have worked across Australian solar and battery systems—from family homes to complex energy infrastructure.
We started close to the customer: designing and delivering residential solar systems, learning how real households use energy and what long-term service actually requires.
As battery technology matured, our focus moved beyond simply installing solar. We developed battery-first capability across system design, integration, diagnostics and performance support. That practical foundation now informs our work on commercial and utility-scale battery assets.
Today, Fexey combines field engineering, controls knowledge and disciplined maintenance delivery. Our people work across battery systems, BMS, EMS, PCS, SCADA, fire systems and supporting plant—bringing the same accountability from the residential customer’s switchboard to the energy assets supporting the grid.

Our journey
Capability that grew with the energy transition.
Battery-first systems
We expanded into tailored residential and commercial battery systems, with a stronger focus on modelling, integration and long-term performance.
Utility-scale energy storage
Our teams now support commissioning, diagnostics, maintenance and controls integration for large-scale BESS and critical energy assets.
What we do
One team across
the asset lifecycle.
Practical field experience, disciplined execution and clear technical reporting—from pre-energisation to long-term asset care.
Commissioning
End-to-end commissioning support for utility-scale battery energy storage systems, from pre-energisation checks through functional testing and handover.
Operations & Maintenance
Planned and corrective maintenance programs designed around asset availability, safety, compliance and long-term system performance.
Technical Response
Experienced field teams for fault investigation, diagnostics, repairs and responsive technical support across Australian energy assets.
Controls & Communications
Integration and troubleshooting across BMS, EMS, PCS, SCADA and plant networks, including Modbus TCP/RTU mapping, gateway configuration and data-path verification.
Integrated engineering
Field capability.
Digital intelligence.
Modern energy assets depend on both hands-on electrical expertise and reliable data. Our engineers work across equipment, controls and communications to find faults at the source.
Control systems
Engineering & system analysis
BMS, EMS and PCS data review, event analysis, functional verification and commissioning support.
Field services
On-site inspection & diagnostics
Electrical testing, visual inspection, fault isolation, corrective work and evidence-based reporting.
Industrial communications
Modbus, SCADA & network integration
TCP/RTU communications, register mapping, gateways, industrial Ethernet and end-to-end signal verification.
Recognition & milestones
A track record built
over time.
Our progress is reflected in the people we train, the customers we serve and the scale of assets we are trusted to support.
Industry engagement
Sharing practical energy knowledge
Customer education, partner engagement and technical conversations have been part of our approach from the beginning.
Technical development
Training-led capability
Continual product, system and field-service training supports consistent delivery as technology evolves.
