Three ways to keep the load up.

Best for

Sites where silence, emissions or fuel logistics are the constraint — occupied areas, monitoring and telemetry, permitted work, anywhere a running engine is the problem you are solving.

The trade

Its ceiling is the sun. Below the break-even load it runs indefinitely; above it, the bank is on a clock and someone has to recharge it.

What it gives you

• Runs silent and unattended
• No fuel delivery, no engine service interval
• Output governed by the inverter, energy by the bank
• Daily solar production published for every configuration

Best for

Continuous-duty sites that cannot stop — where a run of bad weather or a heavy shift must not become an outage, and one trailer has to answer for all of it.

The trade

One machine to move, one machine to service, and it burns fuel when the sun does not cover the day. The specification publishes how many engine hours that is at each load.

What it gives you

• Automatic backup — the engine is a fallback, not the source
• Solar keeps working through daylight whether the engine runs or not
• Fuel consumption published at half, three-quarter and full load
• One tow, one setup, one service call

Best for

Loads beyond what a trailer-mounted engine can carry, and sites that already have a generator. The pairing adds silent hours to a machine that would otherwise run all day.

The trade

Two units to move and to position. In exchange the generator is sized to the site rather than to the trailer, and it charges at the inverter's full rate instead of the reduced rate a mounted engine is commissioned at.

What it gives you

• The generator is chosen for the site, not fixed by the chassis
• It carries the load and charges the bank at the same time
• Engine off once the bank is charged — the solar day is unchanged
• Either unit can be serviced or replaced without the other
