Tesla Resources
The Manufacturer Resource Articles document the most common issues and difficulties when entering a particular manufacturer's equipment into SolarAPP+. If you see an issue that is not documented or needs improvement/ changes. Please reach out to [email protected]
Tesla Powerwall 3 expansion units are not currently supported!!
Please take these Tesla projects directly to your AHJ until our Development team launches support for this ESS system expansion unit.

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.
