Note This is the Datasheet for the Tesla Solar Inverter below.
R559 Error on SolarAPP+
MODULE ISC(13.66) * 1..25 = 17.075 Exceeds limit of MPPT Input of Tesla Inverter.
SolarAPP compares the Isc at a high irradiance factor (125%) in accordance with [NEC 690.8(A)(1)(a)(1) -> This is sometimes in the industry referred to as the "high irradiance factor".
Suggestions use smaller wattage module 415- 420 series.
13.58 * 1.25 = 16.975
You can use the bonding jumper to get up to 25 amps of Short Circuit ISC Current.

Notes: When Installing with Microinverters/AC Modules in an AC Coupled System.
Tesla enforces a PV-to-Powerwall ratio for determining if 3rd party PV sources can be included in the backup circuit. Each Powerwall unit in the backup circuit (Powerwall 2, Powerwall+, and Powerwall 3), can support 7.68 kW AC of 3rd party PV sources in the backup circuit, in addition to any PV DC sources that are wired to the Powerwall+/3 unit. If the PV sources are from the Tesla Solar Inverter, they are not factored into the PV to Powerwall ratio and can be added into the backup circuit.
