SolaX ESS-Aelio Energy Storage Solution for Pachmax Egg Packaging Production Plant in Poland

Located in Środa Wielkopolska, Poland, Pachmax specializes in egg packaging and sales, operating facilities that require a consistent and reliable electricity supply.

Among its energy-intensive operations are cold storage rooms for liquid egg products, which operate 24 hours a day. With continuous electricity consumption, managing energy costs is essential to maintaining operational efficiency and business competitiveness.

While solar PV helps meet the facility's daytime electricity demand, solar generation alone cannot fully cover its round-the-clock energy needs.

To maximize the value of its solar installation and reduce electricity expenses, Pachmax turned to battery energy storage as a smarter and more flexible energy management solution. The integrated PV and storage setup also supports the company's electric vehicle charging needs.

Project Overview

Project Challenge: Optimizing Energy Costs for Continuous Operations

For businesses with round-the-clock operations, managing electricity consumption while controlling energy costs is a key priority.

At Pachmax, cold storage facilities for liquid egg products operate 24 hours a day, creating continuous electricity demand.

The facility faced three key energy management challenges:

• Continuous Energy Demand: Cold storage operations require electricity throughout the day and night.

• Solar Energy Utilization: While the existing solar PV system supports daytime electricity consumption, battery storage can help extend the use of solar energy beyond daylight hours.

• Electricity Cost Optimization: Making better use of available solar energy and optimizing electricity consumption can help reduce operating expenses.

In addition, the company operates an electric vehicle fleet. Making use of on-site solar generation and stored energy for EV charging creates another opportunity to improve energy utilization and manage charging costs.

By integrating battery storage with its existing solar installation, Pachmax aimed to improve energy utilization and achieve more cost-effective electricity management across its facility and EV charging operations.

The SolaX Solution: ESS-Aelio P39B200 C&I Energy Storage System

Working with local installer Solar Volt and distributor 7SUN, Pachmax deployed the SolaX ESS-Aelio P39B200, integrating a 39 kW hybrid inverter with 200 kWh of battery energy storage capacity.

The system works alongside the facility's existing solar PV installation, enabling surplus solar electricity to be stored and used when needed.

Beyond solar self-consumption, ESS-Aelio offers intelligent energy management capabilities that help businesses optimize electricity usage according to different tariff periods.

By supporting charging during lower-cost periods and discharging when electricity prices are higher, ESS-Aelio creates additional opportunities to reduce energy expenses, including during seasons with limited solar generation.

Its advanced energy management capabilities also support flexible energy strategies, including dynamic tariff optimization and energy market participation where applicable.

In addition, the system provides backup power capabilities, adding another layer of flexibility and reliability to the facility's energy infrastructure.

Supporting EV Charging with Solar Energy

The integrated PV and energy storage solution also supports Pachmax's electric vehicle charging needs through the SolaX Smart EV Charger G2. According to the installer, solar energy generated during the day can be used to charge the company's electric vehicles, while stored energy makes it possible to charge vehicles at night as well.

The installer reported that, with the SolaX energy storage solution, EV charging had become 'completely free' under the site's operating setup. This demonstrates how combining solar generation with battery storage can help the company make better use of its own energy, reduce reliance on grid electricity for charging, and support the operation of its electric vehicle fleet.

Project Results: Turning Energy Storage into Business Value

The Pachmax project highlights how intelligent energy storage can deliver measurable benefits for commercial and industrial businesses.

With the SolaX ESS-Aelio P39B200, Pachmax has gained a more flexible approach to managing its electricity consumption, improving solar energy utilization and optimizing costs through smarter energy scheduling.

The reported daily electricity savings of approximately PLN 200 during the initial operating period demonstrate the potential of combining energy storage technology with appropriate tariff configuration.

Beyond immediate energy cost benefits, the system provides a foundation for more efficient energy management and greater operational resilience.

And lower EV Charging Costs: Enables the company to use stored solar energy to charge its electric vehicle fleet, even at night, reducing reliance on grid electricity.

Powering a Smarter Energy Future for Businesses

The Pachmax installation demonstrates that the value of C&I battery energy storage extends beyond simply storing solar electricity.

Through intelligent energy scheduling, improved solar self-consumption, and flexible tariff-based optimization, SolaX ESS-Aelio helps businesses take greater control of their energy costs and consumption.

By also supporting electric vehicle charging with solar energy stored during the day, the solution helps Pachmax extend the value of its renewable energy beyond the factory's immediate electricity needs.

From food production and cold storage to other energy-intensive industries, SolaX continues to support businesses with smart, flexible, and reliable energy storage solutions.
