Overview
Maximize your energy independence and home efficiency with the PITTAR GROUP High Voltage All-in-One Stackable ESS. This integrated energy storage solution combines a high-voltage lithium battery pack, a hybrid inverter, and an intelligent energy management system into one sleek, modular cabinet, designed for modern homes.
At its core, the system uses the safest Lithium Iron Phosphate (LiFePO4) technology, offering over 6000 cycles at 80% depth of discharge for long-lasting reliability and peace of mind. The innovative modular design allows you to start with a single module (e.g., 10.24KWh / 204.8V 50Ah) and easily stack additional battery layers to reach a total capacity of up to 20.48KWh and a voltage of 409.6V, adapting to your growing energy needs without replacing the entire system.
The built-in hybrid inverter supports a maximum PV input of 6000W and features 2 independent MPPT trackers, ensuring high efficiency in converting solar power. It offers flexible operation modes – hybrid, off-grid, and grid-connected – automatically switching to UPS-level backup power in under 20ms during a grid outage. With WiFi and Bluetooth connectivity, the free mobile APP puts you in full control, enabling real-time monitoring, remote control, and intelligent energy scheduling to maximize your savings.
Experience quiet, emission-free, and intelligent energy management for your home.
