48V 300ah 15Kwh Lithium Solar Battery Rechargeable Storage Lithium Ion Batteries

Power Through Your Day: Sunpok 51.2V 300Ah Home Energy Storage

Imagine a major storm hits. The grid goes down, but your home stays bright, your fridge stays cold, and your essential devices stay powered. The Sunpok 51.2V 300Ah Home Energy Storage unit is designed to provide that essential peace of mind. This substantial lithium-ion battery system offers substantial power capacity specifically engineered for reliable home backup.

​​Your Home's Energy Reserve​​
At its core, the Sunpok unit delivers a robust 15.36 kWh energy reserve. That's substantial power on tap for:

• ​​Extended Backup:​​ Keep critical systems like refrigeration, lighting, communication, and medical devices running during extended outages.
• ​​Daily Optimization:​​ Store solar energy generated during the day for use at night, helping maximize the benefit of your solar panels and reduce grid reliance during peak times.
• ​​Off-Grid Potential:​​ A key component for cabin or remote home energy independence when paired appropriately with solar generation and power management systems.

​​Engineered for Power and Longevity​​
Sunpok focuses on core, reliable technology:

• ​​High-Capacity Energy Storage:​​ The 300Ah rating provides significant runtime for essential loads. Specify the usable capacity relevant to your setup.
• ​​Intelligent Battery Management System (BMS):​​ Continuously monitors cell voltage, temperature, and current, ensuring balanced charging/discharging (±0.05V balance precision) and providing critical protection against over-charge, over-discharge, over-current, and short circuits. Focuses on maintaining battery health and safety.
• ​​Stable Voltage:​​ The 51.2V nominal voltage integrates efficiently with common off-grid and hybrid solar inverters suitable for this voltage level.​​

​​Simple Integration for Home Use​​
The Sunpok 51.2V 300Ah battery is designed for straightforward setup with compatible equipment:

• ​​Built for Resilience:​​ Its IP21 rating ensures sufficient protection against vertical dripping water and dust ingress for indoor installation.
• ​​Compatibility First:​​ Seamlessly connects with a wide range of popular hybrid and off-grid inverters supporting 51.2V systems. Always confirm compatibility with your specific inverter brand and model.
• ​​Scalable Design:​​ While a significant unit on its own, its voltage allows for potential future capacity expansion by adding parallel units when your power needs grow (consult Sunpok for parallel configuration guidance).

​​Safety and Reliability You Can Trust​​
Safety is paramount:

• ​​Inherent LiFePO4 Stability:​​ The chemistry is fundamentally safer and more stable than older lithium-ion types, reducing risks like thermal runaway.
• ​​Protection Layers:​​ The multi-level BMS acts as the first line of defense against electrical faults.
• ​​Passive Safety Design:​​ Robust casing and internal construction prioritize safe operation. Follow all manufacturer installation requirements.

​​Sunpok: Power for Your Essentials​​
The Sunpok 51.2V 300Ah Home Energy Storage unit focuses on delivering substantial power capacity and long-term reliability. It’s built to provide essential backup during outages and store solar energy efficiently, helping you manage your home's energy consumption. Its robust LiFePO4 cells and intelligent BMS prioritize safety and durability year after year.
