Renewable energy solutions for a sustainable tomorrow
Field approach
This is not a sales pitch. It is a list of practical outcomes from our O&M work, written the way we talk to facility managers and EPC contractors on site.
We translate inverter fault codes into a clear sequence of checks. Instead of a generic error list, you get the likely causes for your specific string configuration and a step-by-step path to clear the fault.
We check your string voltages against real site temperature data, not just the module datasheet. This prevents overvoltage trips on cold starts and avoids clipping losses when bifacial gain is highest.
We compare cleaned vs. uncleaned string performance to quantify actual soiling impact. This tells you when washing is worth the water and labour, instead of following a fixed calendar.
We walk through Eskom grid code requirements and municipal paperwork with you, so you know exactly which documents to prepare and what relay settings to verify before commissioning.
We review your battery control settings against actual load and tariff data. The result is a dispatch strategy that reduces peak demand charges without compromising backup availability.
We follow a strict DC isolation procedure and use thermal scanning to spot hot connections before they become arc flash hazards. Your team gets a clear checklist for safe maintenance.
A typical engagement runs from the first site assessment to the final handover report. The timeline below reflects the way we actually run O&M and commissioning work, including the paperwork that often takes longer than the technical fixes.
Week 1
We start by pulling the inverter logs, string-level current readings and any fault records you have on hand. If the plant is already live, we also review the performance ratio data to spot underperforming strings before we set foot on site. This step tells us what to bring and which checks matter most.
Week 2
We walk the array with an IR camera, checking combiner boxes, DC isolators and terminations for hot spots that indicate loose connections. Inverter fault codes get verified against the actual hardware, not just the log. You get a field report with photos and a clear list of what needs attention.
Week 3–4
Faulty DC switches, string combiners and communication modules get replaced with parts that match the original specification. We also handle string reconfiguration where the sizing check shows a mismatch. All work follows the lockout procedure for DC switchgear, and we document every change in the maintenance log.
Week 4–6
If the project involves a new connection or an upgrade, we prepare the application for municipal approval and handle the protective relaying coordination study. This is where delays usually happen, so we keep the documentation moving while the technical work is being completed on site.
Week 6–8
We run a final performance ratio test over a full day of operation, comparing the results against the baseline from the first visit. You receive a close-out report with the measured data, the list of completed actions and any recommendations for future maintenance intervals.
Continuous
After handover, we stay available for remote troubleshooting and scheduled check-ins. If a new fault code appears or the performance ratio drops unexpectedly, you have a direct line to an engineer who already knows the plant's history and can guide the next step without starting from scratch.
