1Introduction

1.1 About this manual

This manual provides the specifications, description, operation, maintenance, and service information for the Mobile Solar SRX-6 solar generator. It is written for the owner and for the qualified personnel who operate, maintain, integrate, or service the unit over its service life.

The SRX-6 produces 120-volt AC power and operates at DC battery and photovoltaic voltages that can cause injury. Installation, service, and any work on energized components should be performed only by personnel qualified to work on AC and DC electrical systems and in accordance with all applicable local and national codes. Read this manual, and in particular Section 2, before operating or servicing the unit.

1.2 Symbols and safety notices

The following notices appear throughout this manual wherever they apply.

Notice	Meaning
WARNING	A hazard that could cause serious injury or death.
CAUTION	A hazard that may cause damage to equipment.
IMPORTANT	Information important to correct operation or maintenance; ignoring it may void the warranty.
NOTE	Useful supplementary information.

NOTE. The notice set above mirrors the convention used in the Outback FXR inverter documentation, so the two documents read consistently for an owner who references both.

2Safety

Every solar generator carries inherent hazards. This section identifies them and the practices that avoid or reduce them. The notices defined in Section 1.2 reappear in the operation and maintenance sections wherever a specific hazard applies.

2.1 General safety

Only qualified personnel should service the unit or work on energized components.
Keep the electrical interface door closed and locked during normal operation.
Wear appropriate personal protective equipment when servicing.

2.2 Electrical hazards

The SRX-6 delivers 120 VAC and operates internally at a nominal battery voltage of 51.2 VDC (48 V class), with photovoltaic input reaching higher DC voltages. These can cause shock, burns, or arc flash.

De-energize and confirm zero voltage before servicing (power-down sequence, Section 5.6).
Each outlet circuit is individually breaker-protected; do not bypass a breaker.

2.3 Battery safety (LiFePO4)

The SRX-6 uses self-heated lithium iron phosphate (LiFePO4) batteries. Unlike flooded lead-acid, they do not vent hydrogen, contain no free acid, and require no watering or equalization.

WARNING — Cold-weather charge lockout. The battery bank is self-heated, which is what allows the rated cold-weather range. The heaters draw from the bank itself. A unit left in deep cold with a depleted battery and no solar or generator input can reach a state where it cannot warm itself enough to accept a charge. The specific low-temperature charge-lockout threshold and behavior are pending confirmation from engineering.³

2.4 Generator and fuel safety

The optional Honda EU3000iS runs on gasoline and produces carbon monoxide.

Do not run the generator in an enclosed space or block its exhaust.
Keep the area around the generator compartment clear and ventilated.
Refuel only with the generator off and cool. Do not smoke or allow open flame near fuel.

2.5 Mechanical and towing safety

Deploy and pin all four outriggers before applying load or using power (Section 4.3).
Re-insert every locking pin; an outrigger arm can retract under load if unpinned.
Do not exceed the 3,500 lb GVWR. Curb weight is roughly 2,520 lb, leaving about 980 lb of margin that a full auxiliary fuel tank and added equipment consume quickly. Weigh the unit as configured before loading it.
Confirm coupler, crossed safety chains, breakaway cable, brake controller, and trailer lights before towing.

3System Description

3.1 System overview

The SRX-6 is a trailer-mounted solar generator that produces 120-volt AC power from a photovoltaic array and a lithium iron phosphate battery bank, with an optional gasoline generator for extended low-sun operation. It is the smallest unit in the SRX Series and the only one built on a single-axle 3,500 lb GVWR platform.

Six major assemblies make up the unit: a fixed-pitch solar array mounted above the chassis; a battery bank in a welded steel frame; the electrical interface holding the inverter, charge controller, system controller, and AC and DC breakers behind a lockable door; an optional generator in a lockable cage on a drop-down service platform; the trailer platform carrying all of it, with four 36-inch outriggers and swing-down jacks for leveling; and remote monitoring hardware reporting status and position over a standard Starlink Mini link.

**Figure 3-1.** SRX-6 system, three-quarter view, deployed. Draft render; replace with approved product photography.⁴

The array has no moving parts and no seasonal adjustment, a deliberate difference from the MS Series. Output is optimized for North American latitudes at a fixed pitch. Exact pitch angle pending confirmation.⁵ The system runs unattended: the generator, when fitted, starts and stops on battery voltage without operator action, and the monitoring link reports status without a site visit.

3.2 Electrical interface

The electrical interface holds the components that convert and control power, behind a lockable door.

Inverter — Outback Power FXR. Converts battery DC to 120 VAC and, when an AC source such as the optional generator is present, charges the battery. Rated 3.6 kW continuous, 6 kW surge.
Charge controller. Regulates solar charging of the battery bank; its DC breaker stays on at all times. Exact model pending confirmation.⁶
System controller — Outback Mate3S. Displays battery volts, charge and discharge rates, and inverter mode, and provides operator controls (Section 5.5).
AC and DC breakers. Individual breakers protect each outlet circuit and the DC subsystems; all remain on during operation.

FIGURE 3-2 — TO BE PHOTOGRAPHED

Four 36-inch outriggers with swing-down jacks and two pin positions. Adjustable-height ball coupler or pintle hitch. Telescopic, removable tongue. Trailer warranty 5 years.

TO BE COMPLETED. Deployed dimensions (array up, outriggers out); and the de-trailerizing procedure, if the "under 15 minutes" claim is retained.

Deployed dimensions — Aaron measures (datasheet value is malformed). Procedure — Aaron.

3.6 Generator (option)

Optional Honda EU3000iS gasoline inverter generator in a lockable cage on a drop-down service platform. 3 kW peak, 2.8 kW rated at 80% load. Sound level 49–58 dB. Onboard fuel 3.4 gal, auxiliary tank 25 gal, 28.4 gal total. Starts and stops automatically on battery voltage (Section 5.4). Generator warranty 3 years.

3.7 Remote monitoring and connectivity

The SRX-6 ships with cloud-connected remote monitoring and GPS via a Starlink Mini (standard). The Outback Mate3S provides the local display, and the system is OPTICS RE compatible for cloud monitoring and control. Status and position report without a site visit.

4Setup and Deployment

4.1 Towing

Couple to a half-ton or larger tow vehicle. Attach and cross the safety chains under the tongue, connect the breakaway cable, adjust the tow vehicle's brake controller, and connect and check the trailer lights before moving.

4.2 Siting

Park on level ground with good sun exposure and clearance around the array and generator compartment. Chock the wheels.

4.3 Deploying outriggers and leveling

Work one corner at a time, before powering on:

Locate the retaining pin on the outrigger arm.
Remove the small safety pin, then pull the larger retaining pin straight out (do not twist).
Slide the arm fully out until the second pin hole is visible.
Re-insert the pin through the outer holes to lock.
Remove the jack pin, rotate the swing-down jack to vertical, reinsert the pin, and crank to the ground.

Done right, the unit sits level with a slight lift off the tires and all four jacks touching ground.

WARNING. Re-insert every locking pin; an unpinned arm can retract under load. Do not crank a jack before its arm is swung down.

Outrigger component detail: locking pin, slide rail, swing-down jack, crank handle.

Operator-guide photos may be reusable at print resolution; confirm or reshoot — Aaron/Travis.

4.4 De-trailerizing (option)

TO BE COMPLETED. The unit is described as de-trailerizable in under 15 minutes by removing the wheels, fenders, axle, and tongue. No step-by-step procedure exists.

Procedure — Aaron. If not documented, the claim should not be repeated.

5Operation

5.1 Power up

Outriggers must be deployed and the unit leveled first.

Enter the combo code and open the electrical interface door.
Turn on the DC breakers (solar, charge controller, and main DC). Leave on at all times.
Turn on the AC breakers. Leave on at all times.
Check the Mate3S home screen for battery voltage and charge status.
Set the inverter to ON and verify AC output shows ~120 V.

Done right, the Mate3S shows "Inv On" with AC out ~120 V, battery voltage stable (50.4–56 V), and no error codes or warning LEDs.

FIGURE 5-1 — TO BE PRODUCED

Mate3S home screen, annotated (battery volts, charge rate, inverter mode).

Operator-guide screen photos may be reusable — confirm resolution.

5.2 Using AC outlets

The unit provides two 20 A NEMA 5-20R straight-blade receptacles and one 30 A NEMA L5-30R twist-lock, all 120 V.⁷ Each circuit is individually breaker-protected. Total continuous output is 29 A at 120 V (about 3,500 W) across all circuits combined, with a 50 A instantaneous surge for motor starting.

NOTE. Exceeding the total causes the inverter to limit output rather than fault; it will not damage anything.

5.3 DC outputs (option)

Optional 12 V, 24 V, and 48 V DC outputs are available. What ships on a standard SRX-6, and the terminal locations, pending confirmation.⁸

5.4 Generator operation

The optional Honda EU3000iS starts and stops automatically on battery voltage; the auto-start threshold is 50.4 V.⁹ Leave the engine switch ON, the choke in, and the fuel valve open (vertical) at all times; everything else is automatic. Turning the key off or running the tank dry stops auto-start and the system will fail to recharge.

5.5 Monitoring system status

The Mate3S home screen shows battery volts, charge/discharge rate, solar input, and inverter mode. Normal operating ranges:

Battery voltage	50.4–56 V (generator auto-starts at 50.4 V)
AC output	118–124 V
Frequency	60 Hz

The Starlink modem's indicator LEDs show the monitoring link; solid green is connected.

5.6 Power down

Reverse the power-up sequence: set the inverter off, then the AC breakers, then the DC breakers. The full owner-level power-down sequence, including whether the charge-controller breaker is ever switched off, is pending confirmation.¹⁰

5.7 Preparing for transport

Unplug all loads. Leave the inverter and all breakers ON so the unit stays powered and reports remotely during transport. Close and lock the box, crank the jacks up, swing the arms in and re-pin, secure the generator cage, extend the tongue, couple to the ball, cross the safety chains, attach the breakaway cable, adjust the brake controller, and connect and check the trailer lights.

6Maintenance

6.1 Recommended maintenance schedule

TO BE COMPLETED. A LiFePO4-appropriate maintenance schedule table. The SRX-6 has no battery watering or equalization, so the MS-era schedule serves only as a coverage checklist.

Confirm intervals — Aaron.

6.2 Solar array maintenance

Keep the array reasonably clean. Inspect panels and mounting for damage after severe weather.

6.3 Battery maintenance

The LiFePO4 bank is effectively maintenance-free. Any periodic BMS check, firmware update, or self-heat confirmation is pending guidance.¹¹

6.4 Generator maintenance

Follow the Honda EU3000iS schedule for oil, air filter, and spark plug. Use fuel stabilizer for storage.

6.5 Trailer and chassis maintenance

Check tire pressure and condition, wheel bearings, lights, and jack operation. Verify torque on the critical connections listed in Appendix C.

6.6 Severe-weather protection

Protect the array and secure the unit ahead of high winds and storms. Detailed procedure to be adapted from MS-era guidance.¹²

7Troubleshooting

Table 9. Troubleshooting
Symptom	Check
No AC output at outlets	Inverter mode on the Mate3S must show ON. Then check that all breakers are on; if one tripped, reduce load before resetting.
Inverter shuts down	Overcurrent (load too high) or low battery (below ~50 V). Reduce load, let the generator recharge if fitted, then restart the inverter via the Mate3S.
Battery draining fast	Total load exceeds solar input. Reduce load; check generator fuel if it auto-starts; confirm all breakers on.
Generator won't start, or starts then quits	Fuel valve must be open (vertical) and fuel present. If it starts then quits after ~10 s, suspect low oil. Engine key must be ON.

TO BE COMPLETED. Owner-level error and warning code table for the FXR inverter and the Mate3S.

Codes from Outback documentation and shop experience — Aaron.
