The ULTRA 5 25.6V 200Ah 100A energy storage units are devices designed to store energy produced by a photovoltaic system. They operate on the principle of collecting and releasing electrical energy at the right time. Solar energy is not available 24 hours a day, and in most homes, the highest energy consumption occurs in the morning and evening when sunlight is limited. Therefore, it is advisable to produce energy under favorable conditions to be used later during peak electricity consumption hours. This allows optimization of electricity consumption and gaining energy independence.

The VOLT POLSKA ULTRA 5 25.6V 200Ah 100A energy storage units are widely used in private spaces (single-family homes) and public spaces (restaurants, hotels, supermarkets, factories, etc.).

• Use of lithium iron phosphate cells (LiFePO4), ensuring long device lifespan and safety.
• Capability of performing approximately 6,000 cycles, allowing multiple charge and discharge cycles while maintaining at least 60% of the original capacity.
• BMS (Battery Management System) that monitors various parameters such as voltage, current, temperature, and state of charge. It also protects the device from over-discharge, overcharge, and extreme temperatures.
• Unique structure that allows parallel connection of storage units for future expansion of the photovoltaic system.
• Modern design and compact size facilitating installation in almost any indoor space.

The VOLT POLSKA ULTRA 5 25.6V 200Ah 100A works with solar inverters—models 4000VA and 6000VA—in a photovoltaic system. The system is practical and can be configured according to the provided instructions.

Proper operation of the energy storage and the inverter is critical for efficient storage and use of energy, ensuring reliable power supply to devices and optimal management of energy production and consumption.

• Energy storage is used to store excess electrical energy and allows its use during periods of higher consumption.
• The inverter is mainly used to convert electrical energy from direct current (DC) to alternating current (AC).
• The inverter can perform monitoring and control functions for the energy storage operations.

The device is intended for users who wish to improve energy efficiency, reduce costs, and increase their energy independence.
