Outcomes

What a technician can do at the end

Every outcome below is assessed somewhere in the track — most of them inside a graded scenario rather than a written question.

  • Walk a roof and a service panel and describe the whole system before touching a tool
  • Run a site survey that the design team can actually build from
  • Isolate DC, AC and battery energy safely, every time, with the right PPE and LOTO
  • Commission a system to spec and prove it with measured, condition-corrected numbers
  • Triage the faults that generate most service calls inside the first fifteen minutes
  • Isolate advanced multi-symptom faults without shotgun parts replacement
  • Run a professional service call from arrival to verified handover
  • Close solar jobs cleanly in EcoService OS with defensible documentation
  • Pass a full four-stage field assessment on a live hybrid system scenario
Phase 1

Core Foundations

System literacy and safety before anything else — naming every block of a live system, following the power through it, and proving isolation on DC, storage and AC.

  1. 01Solar fundamentals for field technicians

    ~55 min

    Learn how a solar system behaves before you touch it. Follow the power from the panels to the service panel. Learn what normal output looks like. Know which parts can still carry electricity after the AC switch is open.

  2. 02Site assessment & system identification

    ~45 min

    Arrive, classify the architecture in three minutes, walk the site ground-to-roof in a fixed order, and separate what the ticket says from the scope the site actually contains.

  3. 03Installation sequence & best practices

    ~50 min

    Learn the order that keeps an installation safe, dry, electrically sound, and ready for inspection. Complete each layer before the next layer hides it.

  4. 04Electrical hazards, isolation & LOTO

    ~80 min

    Learn where electrical energy remains after a shutdown. Follow one isolation method every time. Prove the work point is safe before touching it.

    2 lessons — Electrical hazards in PV · Isolation and LOTO that actually holds

  5. 05Working at height, battery hazards and emergency response

    ~80 min

    The two hazards that put PV technicians in hospital most often — a fall and a battery — plus the first five minutes of an emergency, taught to US, Kenyan and South African expectations.

    2 lessons — Working at height and roof work · Battery, PPE and emergency response

  6. 06Wiring, earthing/bonding and protection

    ~115 min

    The electrical half of an installation: what has to be bonded and how it is proven, what each protective device is actually for, and the conductor decisions that quietly cost yield for a decade — taught to US, Kenyan and South African expectations.

    3 lessons — Earthing and bonding fundamentals for PV · DC and AC protection basics · Conductor selection and volt-drop awareness

  7. 07Testing, commissioning and handover

    ~115 min

    Prove the installation before it is energised, prove the behaviour after it is, and leave behind a record that stands up to a US inspection, an EPRA installation record or a South African Certificate of Compliance.

    3 lessons — Pre-commissioning checks and the safe energisation sequence · Functional commissioning of PV and hybrid systems · Handover documentation and performance awareness

Phase 2

Equipment Depth

How modern hardware actually behaves: inverter conversion stages and protection logic, module-level electronics, storage and battery management, and the conditions that drive fault codes.

  1. 08String inverters — operation & service

    ~55 min

    Learn what inverter faults mean before you reset or replace anything. Sort each code into a fault family. Then measure the condition that family predicts.

  2. 09Microinverters & module-level power electronics

    ~50 min

    Work effectively on Enphase-style and optimizer systems, where the diagnosis lives per module and the comms layer lies to you.

  3. 10Battery storage systems (AC & DC coupled)

    ~55 min

    Learn how a battery adds stored energy, separate isolation points, and automatic protection behavior. Tell a battery protecting itself from a battery that has failed.

  4. 11Monitoring systems & performance data

    ~45 min

    Use monitoring the way a senior tech does — to find problems before the customer calls, and to explain them once they do.

Phase 3

Commissioning & Real Diagnostics

Measurement that stands up — condition-corrected numbers, commissioning to spec, and structured fault narrowing on multi-symptom calls instead of parts substitution.

  1. 12Commissioning & acceptance testing

    ~55 min

    Learn to prove a new system works before handover. Run each check in order. Record the expected value beside the measured value.

  2. 13First-line diagnostics — the 80% problems

    ~45 min

    Triage the handful of faults that make up most service calls, and know what to check in the first fifteen minutes.

  3. 14Advanced troubleshooting logic

    ~55 min

    Systematically isolate the faults that survive the easy checks — without shotgun parts replacement.

  4. 15Electrical measurements that matter in solar

    ~50 min

    Take the right readings, in the right conditions, and interpret them correctly instead of guessing at 'out of range'.

  5. 16Fault-finding, diagnosis and maintenance

    ~165 min

    A repeatable diagnostic method, the DC-side and hybrid fault families behind most call-outs, and the preventive maintenance discipline that keeps systems off the fault list — documented to US inspection, EPRA field-record and South African CoC expectations.

    4 lessons — The structured fault-finding method · DC-side and array fault patterns · Inverter, AC-side and hybrid or battery fault patterns · Preventive maintenance basics

Phase 4

Service Excellence & Platform Mastery

Running a professional service call end to end: arrival, evidence, decision, verification, customer handover, and defensible documentation in EcoService OS.

  1. 17The professional service call

    ~45 min

    Run a service call end to end: arrival, customer conversation, diagnosis, repair, verification and handover.

  2. 18Documentation, warranty and liability

    ~45 min

    Learn which records protect the customer, technician, and company. Build the record while the work is visible, not later from memory.

  3. 19EcoService OS mastery on solar jobs

    ~45 min

    Run the whole job through the platform — dispatch, work order, Maya diagnostics, parts, photos, invoice.

  4. 20Capstone — full field assessment

    ~90 min

    One real callout, four graded labs: work it safely, diagnose it, verify it, and document it like a senior technician.

  5. 21Documentation, handover and regulatory awareness

    ~95 min

    The records that make the work safe, warrantable and defensible: why documentation exists, what belongs in a commissioning and handover pack, and which regulatory artefact each market expects — US permit and inspection, Kenyan EPRA-oriented records, South African CoC and PV GreenCard.

    3 lessons — Why documentation matters · Commissioning and handover pack contents · Regulatory artefacts by region

Assessment

How the track is graded

Labs ask for a decision, not a definition.

Scenario labs

Sequence, diagnosis, safety and checklist labs put you on a real call and ask what you would do first. Choices are weighted by diagnostic value; unsafe choices fail the lab outright.

Senior debrief

After grading, each lab explains what you got right, what would have been costly or dangerous, and what a sharper technician would have done differently.

Four-stage capstone

The final module runs one continuous hybrid-system scenario across four stages — arrival and safety, narrowing, decision, and verified handover.

On the job

Where EcoService OS fits

Training builds the judgment. The operating system is where that judgment gets applied cleanly.

EcoService OS is an operating system built for technicians. The call runs in sequence — arrival, site context, evidence capture, problem narrowing, decision, verification, handover — and every stage leaves a record behind. Photos and measurements attach to the asset rather than a message thread, customer communication is written rather than verbal, and follow-ups persist as records instead of intentions.

The final phase of this track is taught inside that structure, because closing a solar job with defensible documentation is a field skill in its own right — and because the same operational pattern carries over into HVAC and other advanced system work as technicians grow.

Before you enrol

Safety and scope

After the labs, you know which exam to book

  • After the labs, you know which exam to book. Prep here for EPRA, NABCEP, EPA 608, NATE, CEC, SAQCC Gas and ESSCI, then book with that body when the labs are done.
  • EcoPowerHub Academy is the prep and issues its own completion record. The examining body is the issuer of the credential you sit for.
  • Work on photovoltaic, battery, and electrical systems involves potentially lethal voltages and must only be performed by qualified persons, in accordance with applicable codes, regulations, and employer safety programs.
  • Labs and materials are educational. The technician and their employer remain solely responsible for safe work practices, isolation, PPE, and compliance on actual jobs.
  • Exam and licence fees are paid to the examining body. Academy completion is training.
