Technical Systems Curriculum
Sixteen modules that build the system understanding and diagnostic judgment modern equipment demands — written for working technicians, supervisors and engineers who intend to stay capable as energy technology advances.
How the curriculum is built
Equipment now reports symptoms rather than causes. A control board names what it detected, and the gap between that and the actual failure is where wrong parts get ordered. This curriculum is organised to close that gap at mechanism level, so the reasoning transfers across platforms rather than being memorised per model.
Built in dependency order
Sensors and loads before control boards. Drives before drive faults. Each module assumes only what the previous ones established, so understanding compounds instead of fragmenting.
Mechanism, not part names
Every module explains how the system behaves when healthy, how it fails, what the failure looks like at the meter, and where the qualification boundary sits.
Judgment under uncertainty
Decision-based scenarios and knowledge checks make you commit to a next step and then show what it cost — the same way the field teaches, without the invoice.
The sixteen modules
Each module carries mechanism-level sections, manufacturer differences across residential and commercial platforms, expected measurement ranges, test procedures with their safety boundaries, failure-mode tables, and decision-based scenarios.

Who this is for
Working technicians
You can already replace parts. The curriculum sharpens the judgment that decides which part — sensors, boards, drives and sequence logic in particular.
Supervisors and leads
A shared technical vocabulary and a documented standard for how a diagnosis should be reached and recorded across a team.
Engineers and career changers
System-level grounding in the equipment you specify, support or are moving into, built from safety and electrical fundamentals forward.
Applied practice runs alongside the modules in the interactive diagnostic labs, and completing a learning path issues a certificate with a verifiable credential ID.
Continuing after the curriculum
Technical capability still has to survive a working day. Graduates can continue developing inside the wider ecosystem: EcoService Pro is an operating system for technicians that runs the call in a defined sequence, keeps problem narrowing and customer communication in one place, and tracks follow-ups — with pathways into more advanced systems such as solar and HVAC. It sits alongside this curriculum under the broader EcoPower Hub AI direction.
