Knowledge & Tips — victron-bluesolar

Why Victron MPPT Controllers Throttle in Heat – Technical Background Victron MPPT solar charge controllers, such as SmartSolar and BlueSolar, feature thermal protection mechanisms that reduce power output once the internal temperature becomes too high. This so-called derating prevents damage to the electronics and is a standard protective mechanism. Causes of Overheating Strong sunlight exposure on the solar charge controller housing High PV output over an extended period Installation in cramped control cabinets or technical rooms Insufficient air circulation Technical Details on Derating Victron MPPT controllers achieve their rated output up to ~40 °C ambient temperature Above 40 °C, automatic power reduction...
