Passive vs. Active Cooling in Victron MPPT Solar Charge Controllers – Technical Differences Many solar charge controllers use either passive or active cooling to dissipate heat. Victron MPPT controllers such as SmartSolar and BlueSolar are no exception. The distinction is technically real: Passive cooling – how it works and when it is sufficient Passive cooling uses natural heat dissipation via the housing and air contact, without any mechanical parts. It is often perfectly sufficient, depending on: Controller power rating Ambient temperature Installation location: open vs. enclosed Thermal contact with metal parts or exterior walls Examples: A low-power MPPT controller in...
