Voltage check against the microinverter datasheets — confirm the pairing on the manufacturer’s module compatibility list. Rows appear only when the panel’s power is inside the microinverter’s recommended module power range.

SolarEdge and other optimizer-based systems size strings by the optimizer rules — use the manufacturer’s designer. Reference inverters: most named in SoCal permits since Oct 2024.

Questions & answers

How efficient is the Elin Energy (Sirius PV) ELNSM54M-HC 410?

Calculated from the panel area (1.95 m²): about 21% for the 410 W class. 410 W over 1.95 m² equals about 210 W per square meter.

How much energy does one panel produce in Los Angeles or Palmdale?

PVWatts v8 with typical-year weather gives about 687 kWh per year per 410 W panel in Los Angeles and about 752 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.332 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.2% below the STC rating.

How many panels fit on one string?

With the Tesla 1538000-xx-y (max DC 600 V, MPPT from 60 V, datasheet) in Los Angeles the calculator gives 3–15 panels per string (Voc at 2 °C = 39.3 V, Vmp at 74 °C cell = 25.3 V). Final design must follow the inverter manual and NEC 690.7.

How big and heavy is it?

67.8 × 44.6 × 1.38 in (1,722 × 1,134 × 35 mm), 47.4 lb (21.5 kg).

Who installs it in Southern California?

Building permits name this series 31 times (Dec 2024 – Sep 2026). The most active licensed installers are South West Builders, Lennar Homes Of California LLC, Sunrun.
