A well-structured request for quotation (RFQ) is the most reliable way to select a supplier for a large-scale commercial and industrial (C&I) energy storage project. Each section asks the supplier to show, in documented terms, how its system will perform for ten years or more. Below are six RFQ sections and the response MPMC, the Shanghai-based manufacturer of HBD-A battery energy storage systems, provides for each.

Six RFQ Sections and a Strong Response to Each

1. Technical Schedule

HBD-A units range from the HBD-125-260 (125 kW / 261 kWh) to the HBD-1000-2000 (1,125 kW / 2,170 kWh), with DC-coupled HBD-DC models of up to 5,015 kWh. All use LFP 314Ah cells rated for 8,000 cycles at 90% depth of discharge, liquid cooling, an IP54 system with IP67 battery packs, operation from -20°C to +55°C and altitudes up to 3,000 m. The HBD-210-410 operates at 690 to 800 Vac for higher-voltage designs, and CE-certified aerosol fire protection is standard.

2. Safety and Construction

The HBD-1000-2000A units delivered to Europe illustrate the standard: a full-weld 20HQ container with reinforced lifting points, C4 coating, ceramic-based aerogel insulation and IP55 protection; 45 CATL LFP battery packs per unit with aerosol fire suppression in every pack; smoke, temperature and humidity alarms; and BMS-EMS linkage with automatic power cut and remote alarm.

3. Controls and Grid Services

MPMC's self-developed EMS and SCADA support PQ, VF, VSG, black start and grid-forming modes for frequency regulation, peak shaving and load balancing, with ten years of data retention, automated reports and an SL3-level cybersecurity framework. Every model supports on-grid and off-grid switching, with seamless switching as an option, plus external PV inverter and ATS integration.

4. Certifications

MPMC operates under ISO 9001:2015, ISO 45001 and ISO 14001, and its products carry CE, TUV, SGS, UN38.3, UL and France BV approvals, with SABER for Saudi Arabia and UN38.3 for battery transport among the market-specific certificates.

5. Warranty and Performance

HBD-A systems carry a 5-year product warranty or 2.2 MWh per kWh of capacity and a 10-year battery performance warranty or 4.3 MWh per kWh, with at least 70% capacity retention at end of life. Remote diagnostics through the SCADA and EMS cloud platform and on-site engineers for commissioning support the system throughout its life.

6. References and Delivery

Ask for projects at comparable scale. MPMC's references include 8 MWh systems in Hungary, the Netherlands and a further European delivery, and twelve HBD-125-260 units recently exported to Oman. Systems are built on automated battery pack and BESS assembly lines at the Yangzhong energy technology base, and every project includes design consultation, customisation, factory testing, logistics and commissioning support, with lead times confirmed for each order based on configuration and production scheduling.

Why Buyers Shortlist MPMC

MPMC's Yangzhong base, opened in 2025 with USD 27 million of investment, combines a 19,000 m² workshop, a 3,300 m² R&D centre, semi-automatic and fully automatic battery pack lines and fully automatic BESS assembly lines, in an industrial base that supplies around 30% of China's high- and low-voltage switchgear. Because MPMC also manufactures generator sets and BCH mobile BESS chargers, a C&I project can add backup generation and EV charging under one EMS, backed by deliveries to more than 120 countries and territories.
