Solar System Testing, Diagnostics & Forensic Investigation South Africa

MicroSec Group provides independent specialist testing, diagnostics, fault investigation and evidence-led forensic assessment for existing electrical, solar PV, battery storage and energy systems across South Africa.

This service is designed for commercial, industrial, residential, facilities and property-management environments where a system is underperforming, repeatedly faulting, behaving unexpectedly, has suffered a significant failure, or requires an independent technical assessment.

Specialist testing and diagnostic services

Depending on the installation and investigation scope, MicroSec can incorporate appropriate electrical measurements, insulation and continuity testing, thermal inspection, inverter and battery diagnostics, protection and earthing assessment, cable and termination inspection, PV string and array assessment, system data and event-log analysis, photographic evidence, installation inspection and engineering analysis. Specialist calibrated test equipment is selected according to the investigation requirements.

Solar PV and battery system fault finding

We investigate existing PV, inverter, BESS and backup-power installations to identify technical evidence associated with poor performance, recurring trips, abnormal temperatures, communication problems, protection issues, cable or termination concerns, equipment behaviour and other system faults. The objective is to establish evidence before recommending corrective work.

Electrical and solar forensic investigation

Where an installation has experienced a serious failure or incident, MicroSec can perform an evidence-led technical investigation. The scope may include site inspection, system architecture review, electrical measurements, thermal assessment, protection and earthing review, historical operating data, inverter or battery event information, photographic evidence and professional technical reporting. Findings are based on the evidence available and the defined investigation scope.

Independent assessment of existing installations

MicroSec can assess systems installed by other contractors. The service is independent and focuses on the installation itself rather than criticising an installer. We examine whether the equipment, configuration, protection, cabling, terminations, earthing, operating behaviour and available system data indicate issues requiring further investigation or corrective work.

SANS-related technical assessment

Where applicable, investigations can include observations relevant to South African electrical requirements and installation practices. Formal compliance conclusions, certification and remedial requirements depend on the installation, evidence, applicable standards and scope of appointment.

Helios-assisted diagnostics and evidence

Where deployed and technically supported, MicroSec Helios can assist with system-data analysis, anomaly and behaviour monitoring, alerts, evidence organisation and professional technical reporting. Helios complements physical inspection and calibrated testing; it does not replace specialist test instruments or competent on-site investigation.

Commercial and industrial solar diagnostics

MicroSec supports commercial and industrial PV, battery storage, backup-power and energy installations nationwide. Services can support owners, facilities teams, property managers and technical stakeholders who need an independent understanding of what an existing system is doing and what evidence should guide the next action.

Nationwide South Africa

Specialist investigation and diagnostic services are available across South Africa, with strong regional coverage from KwaZulu-Natal including Ballito and Durban. Project scope, travel, specialist equipment and reporting requirements are established according to each investigation.
