Sunpok Energy Storage: 51.2V 400Ah LiFePO4 Battery for Serious Home Power
Take control of your home energy with substantial capacity. Sunpok delivers core power storage through our 51.2V 400Ah Lithium Iron Phosphate (LiFePO4) Battery – engineered for homeowners prioritizing energy independence.
Unmatched Capacity & Reliability
At its core lies 20.48 kWh of usable energy, designed to:
Sustain critical appliances (refrigerators, lights, medical devices) during grid failures.
Maximize solar energy utilization by storing daytime surplus for peak evening use, reducing your electricity bills.
Expand your power reserve with multiple units (ensure inverter compatibility for parallel connection).
Engineered for Long-Term Performance
LiFePO4 Technology: Built on inherently safe, stable lithium iron phosphate chemistry, prioritizing security and enduring 8,000+ charge cycles while retaining usable capacity.
Space-Conscious Design: A streamlined vertical form factor minimizes floor space requirements for practical indoor installation.
Comprehensive BMS Protection: An advanced Battery Management System safeguards against over-voltage, over-current, overheating, and short circuits, while ensuring cell balance.
Robust Construction: Heavy-duty steel casing provides impact resistance and secure mounting for internal components.
Technical Specifications
Nominal Voltage: 51.2V
Rated Capacity: 400Ah
Usable Energy: 20.48 kWh
