Event power without a diesel generator

At events the generator rarely fails on power — it fails on noise and permits: exhaust, engine sound, separation distances. Storage needs none of that, and still does not drop out when the band plays the chorus twice.

What drives event power planning

Plan in peaks, not averages. Lighting cues, amplifiers and haze machines ramp up together; the peak defines the system, not the evening average.
Separate continuous from peak load. Stage tech and cooling run through, light and sound in waves — two separate circuits keep the system smaller.
Check noise limits before planning a generator. City centres and residential areas often exclude combustion entirely; the permit decides, not the price.
Plan reserve for encores. A set running ten minutes longer is the normal case, not the exception.

From a small set to a stage

One unit: small stage, radio mics, mixer, lighting — the case nobody wants to keep a generator for.
Two units in parallel: sound and light separated, plus cooling; one circuit does not fail when the other hits its peak.
Three units plus distribution: 400 V for larger lighting rigs and chain hoists, with the load spread across three units.

P-series parallel power systems

One modular platform. Add parallel units where the load grows — two or three units single-phase, or three units for 400 V three-phase.

Wiring

The parallel distribution unit carries one power input and one data input per battery unit, and a single output to the load.

AC230V/20ATwo P25 units, 230 V single-phase.
AC230V/30AThree P25 units, 230 V single-phase.
AC400V/10AThree 230 V P25 units in parallel make 400 V three-phase — all three required, or the system loses a phase.

How the parallel link is wired

Each P25 runs one power cable and one data cable to its own input pair on the distribution unit.
The distribution unit has three input pairs (L1 / L2 / L3); one pair per battery unit.
Only the distribution unit output feeds the load. Battery units are never connected to the load directly.
Each unit keeps its own protective device; no unit back-feeds another.

Three configurations, one platform

Start with a single unit and add parallel units only when the load demands it. Every configuration runs the same battery unit and the same distribution unit.

For rental and event tech

OEM and ODM: we work with partners on these projects — from custom logo printing to adapted configurations.
For rental, turnaround counts: no fuel station, no cold start, no waiting between two events.
Tell us the loads, the voltage and the quantity — we confirm feasibility, required tooling and lead time.

Why not diesel at events

No exhaust at the venue: no separation distances, no argument with the authority about placement.
No engine noise — at concerts with acoustic passages, the difference between possible and impossible.
No refuelling during the event, no supervision effort across the runtime.
Fanless cooling: confetti, dust and haze fluid cannot block an intake.

Data sheet and dealer terms

Three details are enough for a sizing: which loads run at the same time, how long the event lasts, and whether three-phase is required.

Frequently asked questions

The questions buyers actually ask before a first order — answered with numbers from our own datasheets, not from a brochure.

Why do diesel generators fail on permits at events more often than on power?

Because exhaust, engine noise and separation distances drive the conditions — in city centres and residential areas often so strict that a combustion unit may not be placed at all.

How do I plan peak load?

Count what ramps up together: lighting cues, amplifiers, haze machines. The peak defines the system, not the evening average.

Why put sound and light on separate circuits?

Because they draw differently: stage tech runs through, light and sound in waves. Separate circuits keep the whole system smaller.

What about encores and overruns?

A set running ten minutes longer is the normal case. Plan reserve instead of sizing to the planned runtime.
