For an equipment rental business, a battery energy storage system is cost-effective when it earns hire revenue for many years, costs little to run and move, and delivers savings customers are willing to pay for. MPMC, a Shanghai-based manufacturer that sells equipment to rental companies rather than renting it out itself, designed its HBD-R Series specifically for the rental market and as a partner for generator sets. Here is where the return comes from.

Five Sources of Return

1. Long Life per Unit

HBD-R units use LFP cells rated for 6,000 cycles at 90% depth of discharge and carry a 3-year system warranty or 1.6 MWh per kWh, plus a 5-year battery performance warranty or 2.57 MWh per kWh, with at least 70% capacity retention at end of life. The warranty is transferable if units are resold within the period, which supports resale value.

2. Lower Running Costs

A specialised rental structure gives up to 50% lower operation and maintenance costs, and remote monitoring through the EMS with 4G or 5G lets depots check units on hire without site visits.

3. Savings Customers Will Pay For

Paired with a generator set, HBD-R keeps the engine at an efficient load and absorbs peaks with millisecond-level response. MPMC's rental and construction cases in Italy and the UK show fuel savings of up to 75% in low-load applications, and in one UK case refuelling moved from every 2 days to every 7 days and maintenance from every 10 days to every 60 days. Product data also shows generator set life extended by up to three times, and silent operation opens jobs with noise restrictions. Seamless on-grid and off-grid switching is standard on HBD-R.

4. High Utilisation Across Markets

The same units move between construction sites, events, oil and gas fields and mines. MPMC references include a 2 MWh event rental system in Chile, 560 kW / 920 kWh of HBD-R units for a construction carbon-reduction project in Australia, and a 500 kWh mining storage plant in Chile. On oil and gas sites, HBD-R works as a Genset Mate for peak shaving and selective generator set shutdown during low demand.

5. Low Integration and Logistics Costs

HBD-R parallels with DSE, ComAp, DEIF, Woodward, Smartgen, CAT EMCP and Cummins PCC controllers, so it works with the generator sets already in the rental yard. A ruggedised structure is built for repeated transport and deployment, PowerLock and CEE plug-and-play connections speed set-up, and forklift pockets and standard container footprints simplify transport.

Building a Range Around Customer Demand

A balanced rental range pairs smaller HVAC-cooled units for cabins, telecoms and silent nights with larger liquid-cooled units for events and high-power peaks, so each hire request can be matched without oversizing. Because all models share the same EMS and controller compatibility, depot teams learn one system.

Larger 1C models carry aerosol fire suppression with an off-gas detector and a water spray inlet, and MPMC provides remote diagnostics and on-site commissioning support. Rental companies can extend their range with BCH mobile BESS chargers and GSB hybrid power stations from the same supplier, and HBD-R units are CE-certified for European hire markets.
