Your Neighbour's Solar Is Your Problem Now

Your EV charger trips overnight. The DNO says the voltage is fine. The charger says otherwise. So who's right? In this video, we dive into one of the biggest challenges facing the modern electrical grid: rising voltages caused by solar PV, battery storage, EV chargers and changing power flows on local networks. We explore ESQCR voltage limits, BS 7671 Regulation 722, open PEN protection, Clause D vs Clause E, EV charger nuisance tripping, voltage rise, solar exports, DNO responsibilities and why some chargers cope better than others. We also investigate a real-world overvoltage problem and look at how the Myenergi Zappi Glo uses ZapSafe technology to provide open PEN protection without relying solely on voltage thresholds, helping reduce nuisance trips while maintaining safety. The charger isn't always the problem. And neither is the electrician.
