How to enter the Tesla Backup Switch or Gateway 2

ISC Amperage Inputs -
R559 Error on SolarAPP+
MODULE ISC(13.66) * 1..25 = 17.075 Exceeds limit of MPPT Input of Tesla Inverter.
Suggestions use smaller wattage module 415- 420 series.
13.58 * 1.25 = 16.975
Or use bonding jumper with larger series string and MPPT Parallel Bonding Jumper

SolarAPP compares the Isc at a high irradiance factor (125%) in accordance with [NEC 690.8(A)(1)(a)
This is sometimes in the industry referred to as the high irradiance factor.
Bifacial Panels have an additional Wild Irrandiance factor of 130% applied to them So ISC AMPS * 1.55 = Max allowable output of module compared to inverter input.
