Getting ready to install a Level 2 Charger for my Model Y SR in Souther California and the electrician recommended I save the $500 on the Gen 3 Tesla Charger and just install a Nema 14-50 outlet and with an adapter and use the mobile connector instead. He said he had a number of issues with the Gen 3 charges when mounted on exterior walls that have direct sun/heat exposure that causes them to shut down / stop charging. He attributes this to more glass on the Gen 3 version. He said the Gen 1 and Gen 2 versions actually worked more reliably in this situation. Would like to hear from any Tesla Gen 3 Charger users who have their charger mounted outside with direct sun/heat exposure if they have been experiencing these issues. Many Thanks
