Sunpok 48V 270Ah 13kWh Sodium-Ion Solar Storage Battery

Product Overview

◼︎ The Sunpok 48V 270Ah 13kWh Sodium-Ion Battery represents the latest advancement in stationary energy storage, leveraging innovative sodium-ion chemistry to address key limitations of traditional lithium iron phosphate (LiFePO4) batteries. Designed specifically for residential and light commercial solar applications, this unit combines high energy density, robust safety, and ultra-long service life in a compact, user-friendly form factor.

◼︎ Unlike lithium-based batteries that rely on scarce lithium resources, sodium-ion cells use abundant, cost-effective sodium materials, delivering a more sustainable and supply-chain-resilient energy solution. The battery maintains stable performance across a wide temperature range, making it suitable for installation in garages, basements, outdoor utility rooms, and remote locations.

◼︎ Each unit comes equipped with a state-of-the-art Battery Management System (BMS) rated at 200A, which continuously monitors cell voltage, temperature, and current to prevent overcharge, over-discharge, overcurrent, short circuit, and thermal imbalance. The built-in Bluetooth and WiFi modules enable seamless remote monitoring, allowing users to track state of charge (SOC), power flow, and battery health via a dedicated mobile app.

◼︎ With support for up to 15 units connected in parallel, homeowners can easily scale their storage capacity from 13kWh to 195kWh as their energy needs grow. The flexible floor-standing design adapts to various installation spaces, while the integrated LCD display provides at-a-glance status updates. Rated for over 10,000 deep charge-discharge cycles, this battery delivers 2–3 times the lifespan of standard lead-acid batteries and outperforms many entry-level LiFePO4 batteries, ensuring long-term return on investment.
