Outdoor battery storage for farms and businesses.

Store your own solar or wind energy in a battery system built for outdoor use.

Outdoor battery storage gives farms and businesses more control over when they use self-generated energy. It can help reduce grid reliance, manage peak demand, and keep your energy supply more stable during outages or grid congestion.

Ecoways helps you choose and connect the right system for your site.

When does outdoor battery storage make sense?

Outdoor battery storage is useful when your business needs more capacity, has space outside, or wants more control over self-generated energy.

It can help if you:

  • generate solar or wind energy
  • have high or uneven energy demand
  • want to reduce peak loads
  • face grid congestion or feed-in limits
  • are adding EV charging
  • need room to scale

Ecoways helps assess what is technically, practically, and financially sensible.

Our outdoor battery models

Ecoways works with different outdoor battery systems because every site has different needs. Some businesses need a compact PV-ready system. Others need scalable storage for larger operations, charging infrastructure, or future expansion.

Pixii - Modular and scalable outdoor storage

Pixii PowerShaper systems are built for businesses that want a flexible, modular battery setup. They are designed for peak shaving, PV self-consumption, market participation, and scalable energy storage.

Pixii systems are available in different configurations, including 50kW / 51kWh and larger 60kW or 100kW systems with up to 225kWh installed capacity. The PowerShaper range uses LFP battery technology and is designed for connected, monitored operation.

Best fit for businesses that want modular storage, future expansion, market participation, EV site support, or a European-built system.

Kaifa - Flexible storage for solar, backup and hybrid systems

Kaifa EcoSave is a commercial and industrial energy storage system for outdoor use. It is available in different power sizes, from 30kW to 125kW, with storage capacities from 104kWh to 261kWh per cabinet. The system supports PV integration, off-grid switchover, liquid cooling, and remote monitoring.

This makes it a strong option for sites where solar energy, inverter replacement, backup power, or a hybrid setup with grid and generation all need to work together.

Best fit for solar-heavy sites, businesses replacing or upgrading PV infrastructure, backup needs, and compact outdoor storage setups.

CESC - Robust outdoor storage for higher-demand sites

CESC Mercury 233 is an all-in-one outdoor energy storage system with 105kW rated AC power and 233kWh rated energy. It uses LFP battery technology, liquid cooling, built-in EMS control, and has a cabinet IP54 rating with IP67-rated battery packs.

This makes it suitable for larger outdoor energy storage projects where reliability, cooling, and higher storage capacity matter.

Best fit for farms, larger business sites, wind and solar integration, and higher-demand commercial energy systems.

Which outdoor battery is right for your business?

The right battery is not simply the biggest one.

Ecoways looks at how your business uses energy, when your demand peaks, how much you generate, and what you want storage to solve.

We assess:

Your solar or wind generation
Your daily and seasonal energy use
Your grid connection
Your peak demand
Your available outdoor space
Safety and access requirements
Backup or off-grid needs
Future plans, such as EV charging or expansion

Outdoor placement, installation and safety

Outdoor battery storage needs the right location. That means enough space for the battery cabinet, safe access for installation and service, suitable cable routes, and a connection point that works with your existing electrical system.

Some outdoor systems also require groundworks, foundation preparation, and specific safety distances from buildings or other site features.

Ecoways checks these requirements during the site assessment, so the battery is not only technically correct, but practical to install and maintain.

Smart control with EMS.

Smart control with EMS

Every outdoor battery system needs smart control.

With an Energy Management System, your battery can respond to your energy use, generation, battery level, tariffs, and grid situation. It helps decide when to charge, discharge, use stored energy, or export power.

That means your battery is not just storing energy. It is actively helping your business use energy more intelligently.

Do I need an outdoor battery?

You may benefit from outdoor battery storage if you generate your own energy, have high peak demand, face grid limits, or want more control over how and when your business uses power.

As energy export becomes less attractive and grid congestion increases, many businesses are looking for ways to use more of their own solar or wind energy on-site. Battery storage can help make that possible.

Ecoways can assess your site and advise whether outdoor or indoor storage is the better fit.

Can an outdoor battery help with grid congestion?

Yes. Battery storage can help reduce peak demand, store excess energy for later use, and make better use of available grid capacity.

While a battery does not solve grid congestion on its own, it can help businesses operate more flexibly within existing grid constraints.

What is the difference between backup and off-grid use?

Backup power allows the battery to support selected critical processes during a power outage.

Off-grid capability goes further, allowing a larger part of the installation to continue operating independently from the grid. Some systems can also continue using solar or wind generation while disconnected from the grid.

Not every battery setup supports these functions by default, so it is important to discuss your requirements early.

Which outdoor battery model do I need?

The right battery depends on your energy use, generation, grid connection, available space, and future plans.

  • CESC is a practical and cost-effective option for adding storage to an existing solar or wind installation.
  • Pixii is highly flexible and suitable for a wide range of projects, from smaller installations to large-scale energy systems.
  • Kaifa can be a strong option when existing solar equipment or inverters are due for replacement.

Ecoways compares the available options and recommends the best fit for your site.

Can an outdoor battery work with my existing solar panels?

In many cases, yes. Ecoways can assess your current solar installation and determine which battery system can be integrated safely and effectively.

Does an outdoor battery need groundworks?

Usually, yes. Outdoor battery systems often require a suitable foundation, cable routing, and enough space for safe installation and maintenance. The exact requirements depend on the battery model and site layout.
