At the core of the Jarrett Power Wall are Class A LiFePO4 cells, renowned for their superior thermal stability and safety compared to standard lithium-ion batteries. Our systems are designed to endure, offering a cycle life of >6000 times. This ensures that
your investment continues to perform optimally for 10-15 years. The ultra-slim “Power Wall” design not only saves floor space but also complements modern architectural interiors, making it an ideal fit for residential garages and utility rooms.
Safety is our priority. Every unit is equipped with a professional 100A/200A BMS that monitors voltage, current, and temperature in real-time. This smart system prevents overcharging, over-discharging, and short circuits, ensuring the battery operates within its safest parameters. Crucially, our BMS is highly compatible, supporting RS232, CAN, and RS485 communication protocols, allowing for “plug-and-play” integration with multiple mainstream inverter brands.
As your energy needs grow, your Jarrett system can grow with you. Our wall-mounted batteries support parallel connection of up to 15 units, enabling massive energy storage capacities of up to 230kWh. This scalability makes it suitable for diverse applications beyond residential use, including:
