24kW (≈30kVA) Portable Solar + Battery Power System - Dorset

Description

Zero-emission primary power with generator or mains backup

We are offering a nearly new, proven off-grid power system at an exclusive price. Designed as a genuine alternative to diesel generation, this 24kW (≈30kVA equivalent) solar and battery solution delivers reliable three-phase power with the flexibility to integrate a generator or mains supply for load-shifting and backup.

Ideal for festivals, glamping sites, campsites, events, temporary works, or any application where fuel costs, noise, emissions, and generator runtime need to be reduced.

System Overview

24kW three-phase PCS (≈30kVA diesel equivalent)
72kWh total battery storage
Up to 24kW of solar input
Generator or mains input for peak load support and resilience
The system can operate fully off-grid, or in hybrid mode where a smaller generator or grid supply is used only when required—dramatically reducing fuel consumption, noise, and idle hours compared with traditional gensets.

Key Benefits

Zero-carbon primary power
Solar and battery first operation with no local emissions.
Hybrid-ready for critical loads
Seamless integration with generator or mains supply for top-up power, redundancy, and load-shifting.
Proven in live festival environments
Successfully powered the Live Nation Rock Retreat (1,000-person glamping site) at Download Festival 2023 and 2024, running 24/7 throughout the event
Reduced generator size and runtime
External supply input is programmable, allowing efficient pairing with smaller generators rather than oversized diesel units.
Portable and practical
Fork pockets and stackable design for easy transport and storage.

Example: Powering a Small Stage (Audio & Lighting)

This system is ideal for a small outdoor stage, handling audio, lighting, and control equipment even during typical UK summer weather.

Typical loads:

PA system & processing: 3–5 kW
Monitors/backline: 1–2 kW
LED stage lighting: 3–6 kW
Control & ancillaries: <1 kW
Total continuous load: ~8–12 kW, well within the 24 kW (≈30 kVA) capacity.

With 72 kWh of batteries, this provides 6–8 hours of silent operation with no solar input and no generator. In poor weather or evening peaks, a small 20–30 kVA generator or mains supply can be connected for battery top-up and resilience, dramatically reducing fuel use, noise, and runtime compared to running the stage directly from diesel.

If you are looking to reduce diesel usage, cut fuel costs, and offer quieter, cleaner power without compromising reliability, this system is ready to deploy.
