Festivals, concerts, sporting events, film shoots and exhibitions need power that arrives quickly, runs quietly in front of audiences, handles sudden surges from stages and broadcast equipment, and leaves as fast as it came. MPMC’s HBD-R Series mobile battery storage, used alongside containerised generator sets, is built for this cycle, and has powered a 2 MWh event rental system in Chile.
Power Through Every Phase of an Event
Build-Up
During construction of stages and structures, loads are light and variable. HBD-R units carry these loads from stored energy, with a generator set running at an efficient output to recharge them when needed, so engines spend far fewer hours running at light load.
Smaller HBD-R units such as the HBD-30-60 and HBD-50-100 suit production offices, catering areas and backstage cabins, while the HBD-100-200 and HBD-250-400 support larger zones.
Show Days
Event peaks from stage power-up, lighting and PA systems can be three to five times the average load. With HBD-R absorbing the peaks and providing instantaneous power quality support, generator sets run continuously at their optimal load point of around 75% rather than being sized for the highest spike. Where noise rules restrict generator set operation, for example after 22:00 or on Sundays, HBD-R carries the site silently.
The battery also smooths transient loads in milliseconds, protecting sensitive audio, video and broadcast equipment from voltage dips when large lighting rigs switch on.
De-Rig
As equipment comes down, loads fall away and the battery handles the remaining lighting and tools, allowing generator sets to be released early.
Units are then collected and returned to the rental yard, ready for the next event after routine checks, and their status is visible remotely through MPMC’s monitoring platform.

A Configuration for Large Events
For major events, MPMC’s recommended configuration pairs containerised SC super-silent generator sets of 750 kVA to 2,000 kVA per unit, in parallel with motorised ACBs, with HBD-R units of 100 kW to 250 kW per zone, seamlessly paralleled through compatible controllers including DSE, ComAp, DEIF, Woodward, Smartgen, CAT EMCP and Cummins PCC. Noise-sensitive zones run on HBD-R alone during restricted hours, and SPK mobile solar arrays add clean daytime energy for outdoor and multi-day festivals.
HBD-R units are compact and transportable, so they can be positioned close to the zones they serve, reducing cable runs across public areas, and they are removed quickly at the end of the event.

In Chile, the 2 MWh HBD-R system provided pure battery power during performance hours, delivering clean, silent supply that kept generator set noise and emissions away from the audience. In China, MPMC’s 7.5 MW event rental supply used six 1,250 kVA Cummins QSK38-G5 units with droop CT, RTD monitoring and protected air inlets for major live events.
HBD-R units use LFP cells rated for 6,000 cycles at 90% depth of discharge, offer up to 50% lower O&M cost through a specialised rental structure, are CE certified, and carry a 3-year system warranty and a 5-year battery performance warranty.
Rental companies building event power offers can combine HBD-R units with MPMC’s containerised generator sets and SPK solar arrays from one supplier, with remote monitoring through MPMC’s SCADA platform.
