I have a 250/100 SmartSolar MPPT.
This is operated at max. 216V and max. 27A. The PV modules have 5kWp.
Ambient temperature is about 23°C
How hot is it allowed to become, at 5000W continuous power?
Connected is a 48V system.
With a temperature sensor enclosed with the Cebro, I measured approx. 51°C at 4000W.
This has been corrected in advance to 23°C room temperature (offset in software = -6°C).
Measurement of the temperature: Centered on the front of the case
Temperature sensor is mounted with 3M 8926 heat conductive adhesive tape.
Cooling of the MPPT = Passive, no forced convection by fan.
Thanks a lot!
