But it has also created a wave of installations that “work” while hiding serious electrical and fire risks.</p> <p>Below are some of the most common safety and compliance failures seen in residential solar installations, especially under load-shedding pressure where speed often beats standards.</p> <h2> 1) Battery cable sizing and uneven lengths </h2> <p>One of the most common faults is undersized battery cables between the inverter and battery bank.</p> <p>Even worse: parallel battery setups with cables of different lengths, which can create uneven current sharing. That leads to excess heat, premature battery wear, and in extreme cases, fire risk.</p> <h2> 2) Missing DC protection between batteries and inverters </h2> <p>It’s surprisingly common to find systems with no proper DC fuse or breaker between the battery bank and inverter.</p> <p>Lithium systems can deliver very high fault currents, and without correct protection, a short circuit can escalate quickly.</p> <h2> 3) Poor cable routing (no trunking, sharp edges, heat exposure) </h2> <p>Loose cabling, no trunking, sharp edges, and tight bends are a recipe for insulation damage over time.<br> This is especially risky inside DB boards and where cables run through roof spaces.</p> <h2> 4) Incorrect AC cable sizing and termination </h2> <p>Inverters can pull and supply heavy current depending on load and surge.<br> If the AC conductors are undersized or terminations are poor, you get heating, voltage drop, nuisance trips, and long-term reliability issues.</p> <h2> 5) Non-compliant equipment in real-world setups </h2> <p>Some systems use equipment that’s not suitable for the intended application, or not compliant for the environment it’s installed in.<br> Often, the homeowner only discovers this when trying to obtain a Certificate of Compliance (CoC) or when insurance questions the installation.</p> <h2> Final note </h2> <p>Solar is not a “plug-and-play” product — it’s a high-energy electrical installation.<br> If compliance and safety are not treated as non-negotiable, the risks are real.</p> <p>For more general information on professional solar system design and safety-first installation principles in South Africa:<br> <a href="https://enerlux.co.za" rel="noopener noreferrer">https://enerlux.co.za</a></p> solar electricalengineering safety southafrica
