Overview
How this machine carries the load.
123-SG-7S82 is the solar-only flagship: sixteen 460 W panels making 7.36 kW, over a 30.4 kWh lithium iron phosphate bank and a 12 kW inverter, on one triple-axle trailer. No engine, no fuel, no exhaust and no noise — and enough harvest and storage to carry a real site load through the night.
The array brings in 31.6 kWh on an average day. Below 1.32 kW the site runs on the sun indefinitely, and at that load the bank alone carries 11.12 hours with no sun, which covers the night. At 2 kW it carries 7.33 hours; the usable energy is 15.2 kWh at the standard 50% reserve and 21.28 kWh at the 30% setting.
The inverter sets the 12 kW continuous rating, surges to 24 kW for 10 seconds and holds 13 kW for 30 minutes, so motors and compressors start from stored energy. Output is 120/240 V or 120/208 V at 50/60 Hz with a 5 ms transfer, from an inverter rated IP65 / NEMA 3R, for operation from -4 to 140 °F (-20 to 60 °C).
For telecom, monitoring and security sites with a steady load around a kilowatt, this is the machine that removes the fuel run entirely. For heavier steady loads, the same trailer pairs with a standalone diesel as 123-SG-7S82-40.
Features and benefits
- Sixteen 460 W panels, 7.36 kW — Communications and monitoring sites that never need fuel.
- 30.4 kWh lithium iron phosphate bank — The night is covered from stored sun, with nothing to hear or refuel.
- 12 kW inverter, 24 kW surge for 10 seconds — Emission-free power for noise- and exhaust-restricted sites.
- IP65 / NEMA 3R inverter — Stands outdoors on site through the seasons.

Every load here runs continuously, and the day is 24 hours — daily draw is the load × 24 h, so 2 kW is 48 kWh. A load that runs an 8-hour shift draws a third of the figure shown and lasts three times as long. Battery-only hours are given at both state-of-charge settings. Solar is a daily energy offset, not an instantaneous power match — over a day it balances, within a day it is not a guarantee of cover.
Size it for your site
Your load, on 123-SG-7S82.
Most sites swing between a low and a high. Enter both, and the hours a day spent at the high, and the figures follow your day rather than a flat worst case. The load is yours — nothing is assumed until you enter it, and nothing that names you is kept; the PDF button builds the engineering sheet from the figures you enter.

Read from the performance table above: engine hours and fuel follow the day's energy, so your day is read at its average load; solar is the published daily figure; battery-only hours are the published bank at your high load. A load held for 24 hours is the worst case at that level. With no days entered it runs indefinitely; a week and a year are your day repeated, at the same sun.
