Hey guys ,
I replaced my Renogy Voyager PWM controller with a Renogy Rover Elite MPPT that includes a temp probe for temperature compensations. After driving the vehicle the Rover Elite gives an "over temperature" fault, reading 80-85C at the battery. Removing the temperature probe from the MPPT to force a 25*C baseline clears this. I've never read of any MPPTs shutting down charging from the battery being too hot to charge... The unit specs give max operating temperature of 65*C, but it appears the unit will fault if the battery is over that, as well.
Has anyone else experienced this?
It seems pretty common theory to place the MPPT within very close distance to reduce voltage drop and ensure internal temperatures of the charger are equivalent to the battery, and if not close enough then to use a temp sensor at the battery. Does the operational theory of this Renogy mean no charging until the battery is cool enough (essentially house batteries in-cabin only)? It took more than an hour for the battery in the engine bay to cool down enough for the MPPT to charge.
