Qoltec Stable Energy storage LiFePO4 for RACK |5.12kWh | 51.2V | 100Ah | BMS| LCD

Store up energy and use it whenever you want!

Stable, reliable, and environmentally friendly power supply at any time of day

Qoltec energy storage will significantly increase the functionality of your photovoltaic installation and provide a stable and environmentally friendly power supply. It efficiently stores surplus energy acquired during the day that cannot be immediately consumed and keeps it available for later use, for example, during power outages or when production is low. When the storage is discharged, the system automatically draws electricity from the grid. Surplus energy can also be fed back into the grid.

Sustainable Energy in One Storage

Precise power and voltage regulation, energy independence, real-time monitoring, and advanced security features

Main functions of Qoltec energy storage:

• You can make the most of the energy you produce and use it later, such as on cloudy days or at night.
• You gain energy independence and security in case of grid failure; the storage also functions in areas without access to the grid.
• You significantly reduce the effects of power grid overload by storing surplus energy.
• The storage regulates power and voltage and eliminates interference that reduces energy quality.
• You support the development of renewable energy sources.
• It features a built-in LiFePO4 lithium-iron-phosphate battery.

LiFePO4 – Technology You Can Trust

Powerful and discharge-resistant LiFePO4 batteries

Qoltec’s energy storages are equipped with extremely powerful and deep discharge-resistant lithium-iron-phosphate (LiFePO4) batteries. These batteries offer a long service life of up to several thousand charge and discharge cycles, are lightweight, and do not suffer from the memory effect that reduces actual capacity. LiFePO4 batteries are environmentally friendly, non-toxic, and non-flammable, enhancing safety in photovoltaic systems.

Choose Full Control, Choose Our Innovative Energy!

Easy monitoring of battery level and other parameters

The product features a multifunctional, easy-to-use LCD display with a control panel, allowing you to monitor the battery status. The display also alerts you to failures, responding accordingly if any parameter exceeds the norm. By combining efficiency with transparency, we give you full control over your energy, step by step, right on the screen.

RACK Cabinet Mounting

Advantages of RACK Energy Storage

Mount your energy storage in a RACK cabinet to optimize space and maintain order. This ensures easy access to your energy management system while creating a professional and aesthetically pleasing installation, ideal for offices, server rooms, or other spaces where efficiency and functionality matter.

BMS – Intelligent Battery Management System

Protection against overheating, overcharging, and deep discharge

Advanced BMS system:

• Constantly monitors and regulates battery operating parameters, ensuring optimal performance and even charging and discharging.
• Protects cells from overheating, overcharging, and deep discharge, preventing battery damage.

Full Operational Safety – Your Energy Storage Works in Complete Safety

The system includes comprehensive security features:

• UVP Protection – Prevents excessively low output voltage, ensuring stability for connected devices.
• SCP Protection – Short circuit protection.
• OVP Protection – Protection against excessively high output voltage, preventing damage to connected devices.
• OCP Protection – Protection against excessively high current on the line.
• OTP Protection – Overheating protection.
