Overview
How this machine carries the load.
123-SG-4S82 is a 12 kW solar generator with no engine at all: ten panels, a 30.4 kWh lithium iron phosphate bank and a 12 kW inverter on a tandem-axle trailer. It is the machine for sites where noise, exhaust or fuel handling are not acceptable, and for loads that run hard in bursts rather than flat out around the clock.
The inverter sets the 12 kW continuous rating and delivers 120/240 V or 120/208 V at 50/60 Hz, with a 5 ms transfer. It surges to 24 kW for 10 seconds and holds 13 kW for 30 minutes, so compressors, pumps and motor loads start without oversizing the system.
The 4.6 kW array harvests 19.8 kWh on an average day, and below 0.82 kW the sun carries the site indefinitely. Above that the bank does the work: 15.2 kWh usable at the standard 50% reserve and 21.28 kWh at the 30% setting — 7.33 hours at 2 kW, or 3.67 hours at 4 kW, with no sun at all.
That makes it a strong fit for lighting, camera and communications masts, and for job-site offices that work by day and idle by night. For a steady load above the break-even, the same trailer pairs with a standalone diesel as 123-SG-4S82-40.
Features and benefits
- 12 kW inverter, 120/240 V or 120/208 V — Electronics ride through a change of source without rebooting.
- 24 kW surge for 10 seconds, 13 kW for 30 minutes — Motor loads are covered without oversizing the system.
- 30.4 kWh lithium iron phosphate bank — Silent night-time power with no fuel, no exhaust and no engine service.
- Ten 460 W panels, 4.6 kW — Lighting, cameras and communications never need a fuel run.

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-4S82.
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.
