Overview
How this machine carries the load.
Most remote telecom and control equipment already runs on 48 V DC, so the most efficient way to power it is not to convert at all. 123-SG-1A10 delivers 48 V DC straight from its battery bank, up to 60 A and 2.88 kW continuous — the charge controller sets that limit — with no inverter in the path to waste energy or to fail.
Three 490 W panels make a 1.47 kW array that harvests 6.3 kWh on an average day. Below 0.26 kW the sun carries the site on its own, indefinitely: radios, sensors, cameras and gateways that draw a few hundred watts never need a fuel delivery.
When the sun is down, the 9.6 kWh sealed gel lead-acid bank carries the load: 10 hours at 0.48 kW, or 3.33 hours at 1.44 kW, with 4.8 kWh usable at the standard 50% reserve and 6.72 kWh at the 30% setting. The bank can discharge up to 5.88 kW for short demands.
It all rides on one single-axle trailer, small enough to tow behind a light pickup and set down at the edge of a road, a well pad or a construction fence line. Size a continuous load at or under the solar break-even and it runs unattended; above it, the table below shows exactly how long the bank lasts.
Features and benefits
- 48 V DC output, 60 A — No conversion losses, and one less component to fail at a remote site.
- Three 490 W panels, 1.47 kW — Sensors, radios and cameras stay up indefinitely with no fuel run.
- 9.6 kWh sealed gel lead-acid bank — Nights and overcast days pass without a site visit.
- Single-axle trailer — Power where it is needed, without a crane or an installation crew.

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-1A10.
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.
