What is the main benefit of an ESS for business?

An ESS combined with a PV system can reduce electricity costs by up to 95%. It lowers dependence on the grid and ensures stable business operations.

How does selling excess energy to the grid work for businesses?

The ESS stores energy from a PV system or the grid during low-tariff hours and sells it when electricity prices are highest. This happens automatically, based on the company’s needs and battery capacity.

Can an ESS work without a PV system?

Yes, an ESS can operate directly with the grid. However, maximum efficiency is achieved only in combination with a photovoltaic, since self-generated energy is free.

How difficult is it to integrate an ESS into existing infrastructure?

The ESS is designed for seamless integration into a company’s existing energy systems. Installation and configuration are handled by our service team, which also provides guidance after commissioning.

Can an ESS be scaled in the future?

Yes. The system is modular, so capacity can be expanded by adding new energy modules as your business grows.

Does an ESS require special training or maintenance?

The system is automated, requires minimal user intervention, and only needs routine technical servicing, which is provided by our team.

What warranty and service are provided for an ESS?

The equipment comes with a 10-year warranty, along with official servicing and support from Proso Energy, an official Huawei partner.

How does automatic control and monitoring of an ESS work?

The system automatically manages charging, discharging, and energy source selection. It also enables real-time cloud monitoring via dedicated apps, allowing you to optimize energy use and control the system remotely.

How does it work?

What is an ESS?

A system that stores energy from both the PV system and the grid to use it later with maximum efficiency.

Today, having a photovoltaic for business is common. But without an ESS, companies lose part of their potential.

Combined with a PV system, it allows you to:

sell energy at the most profitable tariff,
store energy at the lowest cost,
reduce peak loads,
optimize the use of generated energy,
increase your company’s energy autonomy.

This solution helps you get the most out of your photovoltaic.

Benefits

Additional benefits
for you!

When designing a system, we take into account your consumption patterns, work schedule, and the specifics of your business.

Proposal based on real data

We install a meter and record your consumption for 5 days to gather precise data on energy use and seasonal fluctuations. Based on this, we design a PV system tailored to your budget, work schedule, and actual needs.

Control in your smartphone

The FusionSolar mobile app lets you track your PV system in real time. All analytics are clear, transparent, and accessible anytime, anywhere.

104 extra days of benefit per year

Over 100 weekends a year, energy generated without “Active Consumer” status simply goes to waste. We officially set up the system so you can sell surplus energy at market price and earn additional income.
