Qoltec Stable Energy storage LiFePO4 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 can efficiently store surplus energy acquired during the day that we are unable to consume at any given time, until it is fully charged for use at a later time when current production ceases or is below demand, e.g. during power cuts. The stored energy is available at all times when the storage is discharged, electricity is drawn from the grid. Surplus energy can also be sent to the grid.

Sustainable Energy in One Storage

Precise power and voltage regulation, energy independence, real-time monitoring and a wide range of security features
Main functions of Qoltec energy storage :

- You can make the most of the energy you produce and use it at a later time, such as on cloudy days or at night,

- You gain energy independence and security in case of grid failure, the storage will also work well in a place where there is no access to the grid,

- You significantly reduce the effects of overloading the power grid by storing surplus energy,

- The storage regulates power and voltage and removes interference that reduces the quality of the energy produced,

- You support the development of renewable energy sources,

- It has 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 batteries - LiFePO4. The advantage of this battery is undoubtedly its long service life of up to several thousand charge and discharge cycles, as well as its lightness and the lack of memory effect, which causes a loss of actual capacity. LiFePO4 batteries do not pollute the environment, are non-toxic and non-flammable, which increases the safety of their use in photovoltaics.

Choose full control, choose our innovative energy!

Easy control of battery level and other parameters
The product features a multifunctional, easy-to-use LCD display with control panel. It allows control and monitoring of the battery status. In addition, the display informs you of failures, reacting accordingly if any parameter exceeds the norm. Combining efficiency with transparency, we provide you with full control of your energy, step by step, on screen, for your convenience.

BMS that is Intelligent Battery Management System

Cell protection against overheating, overcharging and deep discharge
Advanced BMS :

- Constantly monitors and controls the battery's operating parameters, ensuring optimum performance, even charging and discharging,

- Protects cells from overheating, overcharging and deep discharge, which can damage the battery.

Full operational safety - your energy storage works in complete safety

Equipped with a comprehensive security kit to protect your system


UVP protection - protects devices from too low voltage at the output, which affects the stability of connected devices,

SCP protection - is a short circuit protection,

OVP protection - is protection against too high output voltage and damage to connected devices,

OCP protection - is protection against too high current on the line,

OTP protection - is protection against overheating.
