SUNPOK 51.2V 100Ah Stackable LiFePO4 Battery | 5.12kWh Residential Solar Energy Storage

Product Overview

Designed for modern residential energy needs, the SUNPOK stackable solar battery combines advanced LiFePO4 chemistry with a user-friendly modular form factor to redefine home energy storage.

Each 51.2V 100Ah module provides 5.12kWh of usable energy. For space-saving indoor installation, up to 6 modules can be vertically stacked without extra mounting hardware. For larger capacity demands, the system supports up to 15 modules connected in parallel, delivering a maximum total storage capacity of 76.8kWh to scale with growing energy needs. The integrated heavy-duty caster wheels make moving and positioning the battery effortless, while its compact footprint fits seamlessly in garages, utility rooms, and basements.

At the core of the battery is a smart Battery Management System (BMS) that delivers 6 layers of comprehensive protection, including cell balancing, overcharge/over-discharge protection, temperature control, and short-circuit prevention. This ensures safe, stable, and efficient operation over thousands of cycles. The battery also supports multiple industry-standard communication protocols (RS232, RS485, CAN), making it compatible with most mainstream solar inverters and energy management systems for seamless smart home integration.

Ideal for maximizing solar self-consumption, reducing time-of-use electricity costs, and providing reliable backup power during grid outages, the SUNPOK stackable LiFePO4 battery is a durable, scalable, and cost-effective choice for residential energy independence.

Key Product Advantages

Application Scenarios

◼︎ Store excess electricity generated by rooftop solar panels during daylight hours, and discharge the stored energy in the evening when solar production stops. This maximizes your self-consumption rate, reduces grid electricity purchases and delivers faster payback on your solar investment.

◼︎ Provides reliable backup power for essential household loads during grid outages, blackouts and extreme weather events. Keep refrigerators, lighting, Wi-Fi routers, medical devices and critical electronics running continuously to protect home safety and daily life quality.

◼︎ Charge the battery during off-peak hours when electricity rates are lowest, and discharge power during peak tariff periods to avoid high utility costs. This arbitrage strategy can significantly reduce monthly electricity bills for households with time-of-use pricing.

◼︎ Delivers dependable standalone power for off-grid cabins, rural homes, vacation properties and remote sites without utility grid access. When paired with solar panels and an inverter, it creates a fully independent off-grid power system.

◼︎ Scalable capacity makes it suitable for small workshops, home offices, retail stores and small commercial facilities. It can be used to lower peak demand charges, store solar generation, and provide backup power for business-critical equipment.
