SOLAR GENERATOR · SOLAR + BATTERY, NO ENGINE

2.88 kW of DC power on a compact canopy: two panels, 9.6 kWh, no engine.

2 × 490 W panels make 4.2 kWh a day into a 48 V bank. Below 176 W the sun covers the whole load and it runs indefinitely — no fuel, no exhaust, nothing to hear.

Overview

How this machine carries the load.

123-SG-900A10 is the simplest way to put 48 V DC power where there is none: two solar panels mounted as a fixed canopy over the battery and controls, on a compact single-axle trailer. There is nothing to unfold and nothing to aim — park it, lower the jacks and connect the load.

The two 490 W panels form a 0.98 kW array that harvests 4.2 kWh on an average day, and below 0.18 kW the sun carries the load indefinitely. That is the territory of monitoring equipment, gateways, sensors and low-power radios: loads that must never go dark and should never need a fuel run.

Output is 48 V DC at up to 60 A, 2.88 kW continuous, set by the charge controller, feeding DC equipment directly with no inverter losses. The 9.6 kWh sealed gel lead-acid bank carries 27 hours at 0.18 kW with no sun at all, and 10 hours at 0.48 kW, with 4.8 kWh usable at the standard 50% reserve and 6.72 kWh at the 30% setting.

Choose it over the three-panel 123-SG-1A10 where the load is lighter and a fast, fixed setup matters more than extra harvest.

Features and benefits

  • Fixed two-panel canopy, 0.98 kW — Setup is park, lower the jacks, connect the load.
  • 48 V DC output, 60 A — More of the harvest reaches the load.
  • 9.6 kWh sealed gel lead-acid bank — Low-draw monitoring runs unattended.

Zero to 2.88 kW, the rated maximum.

How long the battery carries the load on its own. Below 0.18 kW the array carries the whole day and the machine runs indefinitely. Above it, these are the hours the bank lasts with no sun and nothing charging, at the standard 50% setting and at the 30% setting.

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-900A10.

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.
