The front face is the entire interface

There is no menu on the P25. Everything decided in operation sits on the front face: output, charging input, solar input, parallel operation, the switch, the display and USB-C. Once these positions have been walked through, the unit can be handed over without quoting a manual.

The output: 230 V / 16 A

Whatever is plugged in here runs directly. The AC output delivers 230 V at 16 A. Cutters, welders and drills go straight in, without an adapter in between. This is the one socket the actual tool lives on.

The charging input: mains, overnight

The charging input is an input — and that is the most common mix-up. Both sit on the front face and both are AC, but this is where the cable to the wall socket belongs. Where the site has a distribution board, the unit charges overnight. It is the least conspicuous way to keep it in service across several days.

The solar input: DC, and only DC

This input is direct current. A 400 W folding panel clicks in here; two panels in parallel put 800 W into the station. Mains voltage does not belong here — the solar input is DC, and a mistake at this position is the most expensive the front face offers.

Six LEDs instead of an app

State of charge is readable from the doorway. The display is six LEDs. When loading out, it is the fastest check there is: does the unit leave full?

USB-C: small consumers

USB-C is meant for phones, tablets and laptops. Tools belong on the 230 V output. The split sounds obvious — and it is still one of the two questions that comes back after every handover.

Parallel operation: two lines, not one

The parallel set-up needs both lines. Between the units go the power line on the parallel power port and the data line on the parallel data port; over the data line the units stay in sync. Both belong to it: one carries the power, the other keeps the units together.

What the front face is not

The P25 is a 230 V machine. For 400 V three-phase there is the P25-T with its own connection layout. And the front face does not replace distribution on site: it puts power out, it does not plan it.

The whole briefing fits on the front face

One walk-through, eight positions, and the handover stands. If you want to make sure of one thing beforehand: that nobody swaps the solar input and the charging input.
