Summer operation of solar systems in motorhomes – managing heat correctly In summer, equipment compartments in motorhomes, camper vans, and expedition vehicles can heat up significantly. Temperatures of 40 to 60 °C are not uncommon. These conditions pose a particular challenge even for high-quality solar charge controllers like Victron MPPT SmartSolar and BlueSolar. How heat actually affects Victron MPPT solar charge controllers Victron MPPT controllers are robustly designed and built for high temperatures. Nevertheless, there are physical limits here as well: Nominal power is generally achieved up to an ambient temperature of approximately 40 °C. If the temperature rises above...

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...
