WhetEnergy 51.2V 840Ah LiFePO₄ Wheeled Energy Storage Battery - 43.008 kWh (WP-512840)
Intro Paragraph
Designed for applications that demand extended runtime and high continuous power, the WP-512840 delivers 43.008 kWh of reliable energy storage in a single mobile cabinet. Featuring triple-parallel 280Ah modules (16S3P) and a PACE 300A BMS, it reduces the need for multiple cabinets, cuts down on complex cabling, and supports deep communication with mainstream 48V inverter systems.

Application-First Positioning
- Off-grid commercial sites - Run longer without generator backup.
- Large residential estates - Power heavy household loads with fewer modules.
- Mobile & trailer-based systems - Reduce setup time with a single-cabinet design.
- Backup for critical loads - Longer autonomy during extended outages.
Performance Highlights
1) Massive Single-Cabinet Capacity
- Feature: 16S3P configuration using premium 280Ah cells, totaling 840Ah.
- Benefit: Delivers 43.008 kWh in one unit, minimizing the number of parallel connections and potential failure points.
2) High-Power Ready
- Feature: PACE 300A BMS with CAN/RS485, supporting sustained high current output.
- Benefit: Ideal for inverter systems requiring stable delivery at 10 kW+ continuous power.
3) Reduced System Complexity
- Feature: One cabinet replaces multiple smaller modules; fewer interconnect cables and breakers.
- Benefit: Simplifies installation, lowers maintenance overhead, and improves system reliability.
4) Optimized Thermal Control
- Feature: End-plate compression (~700 kg) per module, steel-belt conduction, and strategically placed venting.
- Benefit: Maintains uniform temperatures across cell banks, extending cycle life.
5) Mobility Without Compromise
- Feature: Heavy-duty Foma wheels, reinforced chassis, balanced center of gravity.
- Benefit: Easy relocation for site changes or mobile power needs without sacrificing safety.
6) Flexible Cell Sourcing
- Feature: Available with Hithium, CORNEX, EVE, SVOLT, GOTION, GANFENG cell options.
- Benefit: Allows customization for budget or premium performance requirements.

FAQ
Q1: How is this different from the WP-512560 model?
A: The WP-512840 uses a 16S3P configuration (840Ah) instead of 16S2P (560Ah), delivering ~50% more energy per cabinet. It's designed for higher autonomy and reduced parallel counts.
Q2: Can it handle heavy motor loads or startup surges?
A: Yes, the PACE 300A BMS supports high surge currents for short durations. We recommend confirming your inverter's surge capacity for best results.
Q3: What is the expected cycle life?
A: Over 8,000 cycles at 80% DOD with premium 280Ah cells; actual performance may exceed rated specs.
Q4: Is transport and installation difficult due to weight?
A: While heavier than the 560Ah model, the reinforced wheeled design and balanced structure make site handling straightforward.
Q5: What lead time should I expect?
A: Typical production and delivery range from 20–45 days, depending on cell brand and customization.
