Solax Inverter Innovation & Technology
Active Cooling system
Active Cooling System – The electronic components inside inverters react very sensitively to high temperatures. Inverters need to be cooled to prevent these components from overheating. In the case of Fronius inverters, active cooling technology is used as standard in all devices. Its aim is to proactively avoid heat fields by using interior fans and to remove warm air in a controlled manner. One or more fans ensure that the air inside the inverter circulates and keeps the temperature low.
By contrast, passive cooling technology – as used in many inverters on the market – relies on natural convection. Large heat sinks are used to keep the internal temperature down.
Basic backup power supply without a battery
Basic backup power supply without a battery – It does not require any additional complex installation work. This supplies single-phase loads with up to 3 kW of continuous power via a protected socket or a small circuit during a power failure. This way, PV system owners can charge a mobile phone or laptop with no problem, keeping them charged during a power outage.
