Only installer and ZIP level is shown — no homeowner names, street addresses or permit numbers. Permits from LA County (unincorp.) come without a contractor license, so they count toward totals but not toward installers. Counts grow as more permit portals are loaded.
The California Energy Commission lists a weighted efficiency of 96.2–97.5% for Tesla 1707000-XX-Y models, measured at six power levels and three DC voltages.
What sizes does the Tesla 1707000-XX-Y come in?
The CEC list includes 2 models from 10 kW to 11.5 kW AC: 1707000-XX-Y, 1707000-XX-Y.
Is the Tesla 1707000-XX-Y certified to UL 1741 SB?
Yes — the CEC Grid Support Inverter List shows UL 1741 SB for all models.
Can the Tesla 1707000-XX-Y be used with a battery?
The CEC lists it as a dc-coupled hybrid (pv + battery). In Southern California permits it was installed with Tesla Powerwall 3 Expansion, Tesla Powerwall 3.
What is the 1707000-XX-Y’s DC input voltage range?
MPPT operating range 150–480 V. CEC tested it at 270–480 V DC.
Who installs it in Southern California?
Building permits name this series 6 times (Feb 2025 – Sep 2026). The most active licensed installers are Qcells For New Homes, Sun Capital Energy, Sunrun.
