Renewable energy solutions for a sustainable tomorrow
We work alongside facility managers, EPC contractors and O&M crews across South Africa. These are the organisations we have supported with commissioning checks, fault diagnostics and grid compliance reviews.
Field support
On-site troubleshooting for inverter trips, string faults and DC switchgear issues at operational plants.
Compliance reviews
Grid code assessments and municipal approval documentation for new and existing distributed PV installations.
Knowledge sharing
Practical field notes and checklists that help your team diagnose problems faster and log data properly.
Most solar O&M knowledge lives in WhatsApp groups, scattered PDFs, and the heads of a few experienced engineers. When those people leave a project, the lessons leave with them. This site is an attempt to fix that: a field journal for the people who actually keep distributed PV plants running in South Africa, written in plain language by someone who has been inside the switchgear.
Every post starts with a real problem: an inverter that keeps tripping on F28, a string voltage that climbs past the limit on a cold Karoo morning, a combiner box running hotter than it should. The writing follows the diagnostic path we take on site, including the dead ends and the checks that save you a warranty call.
Grid code compliance and municipal paperwork are not glamorous, but they are where projects stall. We break down Eskom requirements, protective relaying coordination, and the approval process so you know what to prepare before the inspector arrives, not after.
Logging performance ratio is easy; logging it correctly is another matter. We cover how to set up your monitoring so the numbers actually reflect what the plant is doing, and how to spot soiling losses or string faults before they show up on your monthly report.
The goal is straightforward: fewer unplanned downtime hours, safer DC switchgear practices, and a shared reference that facility managers and EPC contractors can rely on. If you are commissioning a new plant or troubleshooting one that has been running for years, the notes here should save you time and help you avoid the mistakes we have already made.
Adani Renewables started as a small O&M crew working on distributed solar PV sites across South Africa. We kept running into the same problems: inverter fault codes that made no sense without context, string designs that looked fine on paper but tripped on cold mornings, and compliance paperwork that nobody could explain clearly. So we started writing things down.
This hub is that notebook, made public. It is written for facility managers, EPC contractors and plant operators who commission new installations or troubleshoot existing ones. The tone is practical, direct and grounded in what we see on site, not in vendor marketing material.
Inverter fault codes, string sizing checks, soiling losses on bifacial modules, Eskom grid code compliance, thermal scanning of combiner boxes and how to log performance ratio data properly.
Every post reads like a field note from an experienced O&M engineer. We describe the fault, the diagnostic sequence and the fix, including the steps that did not work so you do not repeat them.
No glossy sales language, no vague promises about system performance. Just the technical detail you need to make a decision or fix a problem on site.
