  • Q4Which fuel types do MPMC generator sets support?

    • MPMC generator sets support four fuel types:

      • Diesel (standard, including HVO/EN 15940 and B20 biodiesel blends on selected CUMMINS models)
      • Natural Gas (electricity efficiency ≥38%, total energy utilization efficiency ≥80%)
      • Methanol (400 kVA / 280 kW available; lower emissions, safe storage)
      • Biofuel / Biodiesel (up to B35 and higher blends; proven on the 18 MW Indonesia project with Cummins KTA50-GS8)

  • Q5What is the difference between the HBD-A, HBD-E, and HBD-R battery energy storage series?
    • SeriesFormPrimary UseCycle LifeCooling
      HBD-AStationaryC&I grid-connected, frequency regulation, peak shaving8,000 cycles @90% DODLiquid cooling
      HBD-EStationarySelf-consumption, backup power, small hybrid6,000 cycles @90% DODHVAC / HVLC (HBD-125-260)
      HBD-RMobileRental market, genset partner, construction/events6,000 cycles @90% DODHVAC (small) / LCAC (large)

      All three series use LiFePO₄ (LFP) cells and are controlled by an integrated EMS. The HBD-A series is the flagship for large commercial and industrial grid-connected applications (125 kW–1,125 kW AC, up to 2,170 kWh per unit, with a 5,015 kWh DC-coupled variant). HBD-E is designed for cost-effectiveness in smaller applications (10–125 kW AC, 30.7–261.2 kWh). HBD-R is purpose-built for the rental market with ruggedized design, millisecond-level load response, and easy maintenance.

  • Q11How does the BESS + Genset hybrid system save fuel in practice?

    • The core principle: diesel engines operate at their most fuel-efficient point only at 75–100% load. At partial load (25% or below), specific fuel consumption rises significantly. The BESS absorbs or supplements power to keep the genset running at its optimal load point at all times.

      From the Dubai Concrete Batching Plant case study (HBD-500-1000 + 3 × 500 kVA gensets):

      • Daily fuel saving: 254.13 liters per station
      • Fuel reduction rate: 10.56%
      • Annual fuel saving: ~92,757 liters per station
      • Annual cost saving: ~USD $70,496 per station (at $0.76/L diesel)
      • OPEX reduction: ~20%
      • Genset life extension: 2–3 years
      • CAPEX payback on hybrid premium: 2–3 years

      From the Italy Rental and UK construction site cases, parallel operation with gensets can achieve up to 75% fuel savings in low-load scenarios (e.g., office/server loads of 3–6 kW running on a 56 kW genset).

  • Q12What grid-forming and grid-support functions do MPMC BESS systems support?

    • MPMC HBD-A and microgrid systems support the following operational modes (as documented in the Kenya 6 MW microgrid case study):

      • PQ Mode: Active and reactive power control for grid-connected operation
      • VF Mode: Independent voltage and frequency control for off-grid operation
      • VSG Mode: Virtual Synchronous Generator — emulates inertia to improve grid stability
      • Black Start: Independent power restoration after grid outage
      • Grid-Forming: Creates a stable power network in areas with no grid
      • Reactive Power Regulation: Full-range reactive power absorption across all PCS units
      • Peak Shaving & Load Balancing: EMS-driven dispatch to reduce demand charges
      • Seamless On-grid/Off-grid Switching: Standard on HBD-R series; transition with gap on HBD-A series (default, can be configured)

  • Q13What is the BCH series' charging connector compatibility?
    • ModelDC Charging OutputConnector Standard
      BCH-80-7080 kWCCS2, 260A × 1

      BCH-800-600600 kWCCS2, 350A × 2
      BCH-500-1000500 kWCCS2, 350A × 2

      The BCH-275-200 and above also support CCS2 DC input for recharging from fast-charging stations (BCH-275-200 fully charged in approximately 1 hour via DC input). Optional connectors including CCS1, GB/T, and CHAdeMO are available for specific markets. All models support simultaneous charge and discharge.

  • Q14What battery cell technology does MPMC use in its BESS products?

    • All MPMC BESS products use LiFePO₄ (Lithium Iron Phosphate, LFP) cells. The HBD-A Series uses 314 Ah cells. The HBD-R Series uses 100 Ah cells (smaller models) and 314 Ah or 265 Ah cells (larger models). The HBD-E Series uses 100 Ah cells (smaller models) and 314 Ah cells (larger models). The HBD-A Series (8 MWh Europe project) uses CATL 1P52S battery packs per published case study materials.

  • Q15Does MPMC's SCADA support remote monitoring and what cybersecurity standard does it meet?

    • Yes. MPMC's self-developed SCADA supports real-time remote monitoring and control, alarm and fault management, maintenance management (early warnings, record tracking, warehouse management of spare parts), automated monthly/annual reports, and customizable operation reports. The system stores up to 10 years of data. It operates on an SL3-level cybersecurity framework. StarLink satellite communication is integrated as a backup link.

Part CCommercial & Purchasing Questions

  • Q16What is MPMC's typical lead time?

      Note: For diesel genset series, the warranty on engines, alternators, and controllers follows the original manufacturer's warranty terms. These can be found on the respective engine brand's official website.

      Battery performance warranty validity condition: battery box temperature must be maintained at 0°C–25°C (±3°C tolerance) and humidity ≤80% during operation.

  • Q20How does MPMC handle after-sales service for generator sets?

    • Diesel generator sets powered by CUMMINS, PERKINS, MTU, BAUDOUIN, SCANIA, SDEC, and Kubota benefit from each engine manufacturer's global service network. Buyers can access authorized local service centers in their region through the respective engine brand's official website.

      For alternators equipped with STAMFORD or Leroy-Somer, after-sales support is similarly available through the alternator manufacturer's global service network.

      MPMC's own warranty obligation for gensets covers manufacturing quality and parts replacement during the warranty period. Labor, travel, and airfreight costs are not included in the standard warranty unless otherwise agreed in the contract.

  • Q21How does MPMC handle after-sales service for new energy products (BESS, BCH, GSB, HSL, HBL)?

    • MPMC provides two layers of after-sales support for new energy products:

      1. Remote support: MPMC's technical team provides remote diagnostics, fault analysis, parameter adjustment, and troubleshooting via the EMS/SCADA platform or direct communication (phone/email). The SCADA system supports real-time alarms, fault records, and remote command functions.
      2. On-site service: MPMC can dispatch after-sales engineers for on-site commissioning, fault resolution, or system upgrades when required.

      To initiate a warranty claim, users must report the fault to MPMC or an authorized agent within 7 days of occurrence, provide fault records and product information, and must not disassemble products without prior authorization. Warranty claims require maintenance records as proof of compliance with the maintenance schedule.

  • Q22What is excluded from MPMC's warranty coverage?

    • The following situations are not covered under any MPMC warranty:

      • Faults caused by incorrect use, transportation, or storage
      • Damage from improper fuel, lubricant, or coolant (for genset hybrids)
      • Environmental damage from extreme weather, contamination (dust, salt, chemicals), strong vibration, or strong magnetic fields
      • Use of temperatures or operating conditions exceeding those stated in the product manual
      • Normal wear parts and components
      • Unauthorized modification or third-party maintenance without MPMC approval
      • Use of non-MPMC-approved spare parts
      • Force majeure events (war, natural disaster, power surge, lightning, flood, fire, etc.)

  • Q23How does MPMC handle warranty disputes?

    • In the event of a warranty dispute, MPMC and the product owner may mutually agree to engage a first-class international testing organization for third-party verification and opinion. Unless otherwise agreed, the costs of the verification procedure are borne by the party requesting it.

      Warranty extension beyond the standard period is available — contact MPMC sales for pricing and terms. All requirements during an extended warranty period are identical to those during the standard period.

  • Q24How do I contact MPMC for technical support or a product inquiry?

    • For warranty claims, contact the MPMC Marketing Department directly or through your authorized dealer. Include the product model, serial number, fault description, and maintenance records in your initial communication.
