Our Testing & Commissioning Services

Solar PV & Energy Storage Systems

Our checks follow internationally recognised practice for grid-connected and off-grid PV systems (IEC 62446-1).

• Visual inspection of panels, mounting structures, cable routing and labelling
• Earthing and bonding continuity tests
• DC string polarity, open-circuit voltage and short-circuit current checks, compared against design values
• Insulation resistance testing of DC and AC circuits
• Verification of fuses, DC breakers, isolators and surge protection ratings
• Inspection of MC4 connectors and terminations for correct crimping and tightness
• Inverter configuration: battery type, charge and discharge limits, grid and generator settings
• Lithium battery BMS communication check with the inverter
• Functional tests of charging, discharging, backup switchover and shutdown
• Output performance check against available sunlight
• Thermal imaging of connections to detect hot spots before they become faults
• Setup of monitoring app or Wi-Fi logger, where supported

UPS Systems

Our checks follow manufacturer procedures and good practice for UPS performance verification (IEC 62040 series).

• Inspection of UPS placement, ventilation and clearances
• Input supply checks: voltage, frequency, phase rotation and neutral-earth voltage
• Battery string voltage, polarity and connection torque checks
• Controlled start-up following the manufacturer's procedure
• Transfer tests: mains to battery, battery back to mains, and bypass operation
• Load testing using resistive load banks to confirm output under realistic conditions
• Backup runtime (autonomy) verification against your requirements
• Alarm, display, buzzer and emergency power-off (EPO) function checks
• SNMP card configuration for remote monitoring and alerts
• Firmware and parameter review

Battery Banks (VRLA, AGM, Gel, Lithium & Nickel-Cadmium)

Our battery checks follow recognised practice for stationary battery maintenance and testing (IEEE 1188 / IEEE 450).

• Individual cell and block voltage measurements
• Internal resistance / impedance baseline readings, recorded for future comparison
• Terminal torque, corrosion and inter-cell connector inspection
• Charger float and boost voltage verification, including temperature compensation
• Ventilation and ambient temperature assessment
• Full capacity discharge testing with DC load banks, available on request

Inverters, Transformers & Voltage Stabilizers

• No-load and on-load output voltage and frequency checks
• Protection function tests (overload, short circuit, low battery, over-temperature)
• Transformer voltage ratio and insulation resistance tests
• Stabilizer regulation checks across input voltage variations

Automotive & Heavy-Duty Batteries

• Open-circuit voltage and state-of-charge measurement
• Cold Cranking Amps (CCA) test with a digital battery analyser
• Starter motor current draw test
• Alternator charging output check
• Parasitic drain check for batteries that keep going flat

Our Process

1. Review & Planning

We review your system design, equipment datasheets and single-line diagram (if available) and agree the test scope with you.

2. Pre-Commissioning Inspection

With the system de-energised, we carry out visual, mechanical and safety inspections of all equipment and connections.

3. Component Testing

Each circuit, string, battery and protective device is tested and every result is recorded.

4. Energisation & Functional Commissioning

The system is powered up in a controlled sequence, configured and run through all operating modes.

5. Performance Verification

We confirm that output, backup time and efficiency meet the design and your expectations.

6. Documentation & Handover

You receive your commissioning report, and we walk you through safe operation of your system.

7. Follow-Up

We check in after the system has been running to make sure everything is performing as expected.

What You Receive

• A detailed commissioning report with all measured values and pass/fail results
• A test certificate signed by our engineer
• A record of all inverter, UPS and charger settings
• Photographs of the installation and key connections
• Warranty registration support with the manufacturer
• A practical handover session on system operation and basic safety
• A recommended maintenance schedule

Professional Test Equipment

Our engineers use professional instruments, including insulation resistance testers, true-RMS clamp meters, battery impedance analysers, thermal imaging cameras and PV testers. Through our group we also have access to a large fleet of AC and DC load banks, allowing us to test UPS systems and battery banks under real load rather than on paper.

Safety Comes First

Solar arrays produce dangerous DC voltage whenever the sun is shining, and batteries can deliver very high currents in a fault. All our testing is carried out by trained personnel using proper isolation procedures, insulated tools and personal protective equipment.

Frequently Asked Questions

My installer already switched the system on. Do I still need commissioning?

Switching a system on is not the same as commissioning it. Many faults, such as loose connections, wrong battery settings or undersized protection, don't show up immediately but lead to failures months later. Proper testing finds them early.

Do you test systems that were not bought from WarbaElectric?

[Yes. We test and commission systems from any supplier, subject to a site review.]

How long does commissioning take?

A home UPS or small solar system usually takes [2–4 hours]. Larger commercial systems, or those needing load bank or capacity discharge testing, may take [one full day or more]. We will confirm the timing when we schedule your visit.

Is testing required for my warranty?

Many manufacturers require installation and commissioning by qualified personnel for warranty claims to be accepted. Our report gives you the documented proof.

How much does it cost?

Pricing depends on the system type and size. [Commissioning is included with WarbaElectric installation packages.] For standalone testing, contact us for a quote
