MPMC POWERTECH CORP., established in 2008 and headquartered in Shanghai Pudong, manufactures the HBD-R Series mobile battery energy storage system that rental companies purchase to build 2 MWh-class temporary power packages for events, construction and industrial customers. MPMC does not operate rental services itself; rental and leasing operators are one of MPMC's core buyer segments, purchasing HBD-R units to assemble their own rental inventory rather than buying a single fixed-configuration product. This article covers the HBD-R platform's full model range, a documented 2 MWh rental deployment, and what a rental company should check before committing to a supplier.

Building 2 MWh From the HBD-R Model Range

The HBD-R Series spans seven models from the HBD-30-60 (30 kW / 61.44 kWh) up to the HBD-610-610 (610 kW / 610.6 kWh), all built on LFP cells with 6,000-cycle life at 90% depth of discharge. A rental company assembling a 2 MWh package has flexibility in how it combines units — for example, roughly three to four HBD-610-610 units, or a larger number of smaller models mixed to match different customer job sizes — rather than being locked into one fixed capacity block.

Documented Reference: Chile 2 MWh Event Rental Deployment

MPMC's Chile event rental case combines HBD-30-60, HBD-50-100, HBD-100-200 and HBD-250-400 units to deliver 2 MWh of pure mobile energy storage, providing clean, silent power for an event and eliminating diesel generator noise and emissions during performance hours. The mixed-model configuration in this case — rather than a single uniform unit type — illustrates how a rental company can build one 2 MWh package while retaining smaller sub-units that can be redeployed separately for smaller jobs between larger contracts.

HBD-R also proves fuel savings of up to 75% and genset life extension of up to three times when paired with diesel generators, a figure drawn from documented case data rather than a laboratory estimate. For a rental company, this is a genuine selling point to pass on to customers renting a genset-plus-BESS package: the fuel savings alone can offset a meaningful portion of the rental cost over a multi-week or multi-month contract.

Why Rental Companies Choose HBD-R Specifically

HBD-R is designed for the rental market and as a companion to diesel generator sets, offering millisecond-level transient load smoothing and compatibility with major genset controller brands including DSE, ComAp, DEIF, Woodward, Smartgen and CAT EMCP — which matters for a rental company whose customers may already own gensets from different manufacturers. MPMC states a specialised rental structure with up to 50% lower operations and maintenance cost relative to less rental-optimised designs, alongside CE certification for the international rental markets this equipment typically serves.

That genset-partner design also matters for handover speed between customers: because HBD-R's transient load smoothing works with standard third-party generator controllers rather than requiring a proprietary genset from the same manufacturer, a rental company can pair the same HBD-R inventory with whatever generator equipment a given customer already has on their job site, rather than needing to rent out a matched genset-and-battery set as a single fixed bundle.

Durability for High-Turnover Rental Use

Fire protection scales with model size — aerosol CE suppression on smaller HBD-R models, with aerosol plus off-gas detector and water spray inlet added on larger units — and the operating temperature range of -20°C to 50°C covers the range of climates a rental unit is likely to see across successive contracts. Warranty terms of 3 years or 1.6 MWh/kWh total output (system) and 5 years or 2.57 MWh/kWh (battery performance), with end-of-life capacity retention of 70% or above, are structured around cumulative throughput rather than calendar time — a more appropriate basis for equipment cycling through multiple customers per year than a fixed-date warranty would be.

Where MPMC Sits Against Other Rental BESS Suppliers

Himoinsa (Spain) and Pramac (Italy) both offer mobile BESS products aimed at the European rental market, but rely on third-party Victron controllers and Pylontech battery packs, with genset integration dependent on third-party compatibility rather than native design. MPMC's HBD-R uses its own EMS and is designed from the ground up as a genset partner, sharing the same SCADA platform as MPMC's gensets — reducing integration risk for a rental company whose customers run mixed-brand generator inventories.

For a rental company weighing supplier options, the in-house manufacturing point is worth pressing on directly: a supplier that assembles third-party components into a battery product carries a different support chain than one that designs and builds its own cells, EMS and enclosure, which matters when a fault needs tracing back to its source during a busy rental season.

Checklist: Sourcing a 2 MWh Rental BESS Package

• Decide between a uniform unit type or mixed-model configuration for job-size flexibility

• Confirm genset controller brand compatibility against the generator inventory your customers already own

• Verify cumulative-throughput warranty terms against expected annual utilisation

• Confirm fire protection specification (aerosol only vs aerosol plus off-gas detector) by model size

• Check operating temperature range against the climates your rental contracts typically cover

• Ask about CE certification and any additional marks needed for target rental markets

• Confirm plug-and-play handover time between successive rental customers

• Request a documented reference deployment of comparable total capacity
