Overview
How this machine carries the load.
123-SG-7S42 carries the full sixteen-panel array — sixteen 460 W panels, 7.36 kW — over a deliberately lean 15.2 kWh lithium iron phosphate bank, on a triple-axle trailer. It is built for work that happens in daylight: the array feeds the load as it harvests, and the bank bridges clouds, the evening and the first hours of the morning.
On an average day the array brings in 31.6 kWh, and below 1.32 kW the sun carries the site indefinitely with nothing to fuel. The 12 kW inverter sets the continuous rating, surges to 24 kW for 10 seconds and holds 13 kW for 30 minutes for motor starts, and delivers 120/240 V or 120/208 V at 50/60 Hz with a 5 ms transfer.
With no sun, the bank carries 5.56 hours at 1.32 kW and 3.67 hours at 2 kW, with 7.6 kWh usable at the standard 50% reserve and 10.64 kWh at the 30% setting.
Choose it where the load follows the sun — daytime construction, events, agricultural pumping — and harvest matters more than storage. Where the load runs through the night, 123-SG-7S82 carries the same array over twice the bank.
Features and benefits
- Sixteen 460 W panels, 7.36 kW — Daytime work runs on sunlight, not on fuel.
- A lean 15.2 kWh lithium iron phosphate bank — The array does the heavy lifting; the bank covers the gaps.
- 12 kW inverter, 24 kW surge for 10 seconds — One machine for tools, lighting and motor loads.
- A folding array on a triple-axle trailer — Moves between sites with one tow.

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-7S42.
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.
