He is in Joshua Tree which is high desert. There is probably a way to check low temperature recorded. That would have to occur around Noon on a clear day to be an issue for the Renogy.
If so there are other All in One inverters or other charge controllers he can research. Perhaps that is what
@JeepDaddy meant by a solution looking for a problem. Often most posters don't have enough solar panels to charge their batteries. In this case the OP has 3.7 kW of solar panels and approximately 10kWh of Tesla modules. The Renogy apparently has a solar capacity of 4.4 kW of solar but a narrow range of voltage. Ten in parallel would not be enough voltage and a 5P2S panel configuration might hit maximum voltage on a very cold clear day at Noon.
