Manufacturer Approval: Ensuring Safe Installations

When investing in a solar PV and battery storage system, the battery and inverter are often the
components that receive the most attention. However, where and how that equipment is housed is
becoming an increasingly important part of creating a safe, reliable and long-lasting energy
system. In many cases, obtaining manufacturer approval for your installation is also a key step. This helps to ensure safety and compliance.

At Eco-ESS, our External Battery & Inverter Enclosures have received written compatibility or
approval confirmation from a growing number of leading energy manufacturers. This includes Fox
ESS, SolaX, Duracell, Sunsynk, Solis and GoodWe.

But what does manufacturer approval actually mean, and why should it matter to homeowners and installers?

Battery and inverter manufacturers provide specific requirements for how their equipment
should be installed and operated. These can include considerations around ventilation,
temperature, positioning, clearances and the environment in which the equipment is installed.
An external enclosure therefore needs to do much more than simply protect equipment from the
rain.

Eco-ESS enclosures have been developed specifically for modern battery and inverter
installations, incorporating features including:

● IP55-rated weather protection
● Thermostatically controlled ventilation
● Heating and cooling
● Secure, lockable construction
● Structured cable entry
● Dedicated mounting solutions
● Protection for equipment installed outside the home

Receiving written approval or compatibility confirmation from equipment manufacturers provides
additional reassurance that the enclosure solution has been reviewed. This relates to the relevant
manufacturer’s equipment and installation requirements.

It gives installers greater confidence when specifying an external enclosure. In addition, it gives
homeowners greater reassurance about how their valuable energy equipment is being
protected.

Approved by Leading Energy Manufacturers

Eco-ESS External Battery & Inverter Enclosures have received approval or written compatibility confirmation from:

Fox ESS
SolaX Power
Duracell
Sunsynk
Solis
GoodWe

These are established names within the solar, inverter and battery storage industry. Their
products are installed across homes and energy systems throughout the UK.

For Eco-ESS, gaining recognition from multiple manufacturers is an important part of our
commitment. We focus on developing engineered solutions that work alongside the technology installers
are already using.

Why Does This Matter for Installers?

For installers, specifying the correct equipment isn’t just about finding products that physically fit
together. You need confidence in the complete installation.

When placing batteries and inverters inside an external enclosure, considerations such as
airflow and temperature management become particularly important. Poor thermal management
could affect how equipment operates and potentially conflict with manufacturer installation
requirements.

Eco-ESS enclosures incorporate active thermal management, including thermostatically
controlled heating and fan-assisted cooling, helping maintain appropriate conditions within the
enclosure.

Manufacturer approval therefore gives installers an additional level of confidence when
specifying Eco-ESS alongside compatible systems.

It can help installers:

● Specify enclosure solutions with greater confidence

● Protect battery and inverter equipment from external conditions
● Support appropriate thermal management
● Provide customers with documented manufacturer confirmation where applicable
● Deliver a more professional, purpose-designed external installation
● Reduce uncertainty when planning battery and inverter relocation projects

Rather than using a generic outdoor cabinet, installers can choose a solution developed
specifically around the requirements of renewable energy equipment.

Why Does It Matter for Homeowners?

A battery storage system can represent a significant investment in your home. Naturally, you want to know that the equipment protecting that investment has been properly
considered.

Choosing an enclosure with manufacturer backing provides another layer of reassurance.
It shows the enclosure has been reviewed for use alongside recognised battery and inverter technology.
Furthermore, the enclosure helps protect equipment from rain, dust, accidental damage and unauthorised access. Its temperature-management systems help create a more controlled
environment for equipment positioned outside.

For homeowners looking to relocate an existing battery or inverter from a loft, cupboard, garage
or other internal area, this becomes particularly valuable. You’re not simply moving the equipment outdoors. Instead, you’re moving it into a purpose-engineered environment designed around the needs of modern energy storage technology.

Supporting Safer, PAS 63100-Aligned Installations, Manufacturer approval is also important within the wider conversation. It is relevant to battery storage installation safety. PAS 63100:2024 provides guidance around the fire safety of domestic battery energy storage system installations, including areas such as installation location, ventilation, fault management and fire protection.

Eco-ESS External Battery & Inverter Enclosures are designed to support PAS 63100-aligned
installations when used as part of a correctly designed and installed system. However, it is important to distinguish the two: PAS 63100 is a code of practice for the overall installation. An enclosure itself is not simply “PAS 63100 certified”.

Final compliance depends on factors including the complete system design, equipment selection, location and installation.

Manufacturer approval adds another important piece to that picture by providing documented
confirmation relating to the equipment being housed within the enclosure.

More Than Just an Outdoor Cabinet

An external battery enclosure should never be treated as simply a metal box. It becomes part of the environment. Sophisticated electrical equipment is expected to operate there every day, throughout changing UK weather conditions.

That’s why Eco-ESS has focused on engineering enclosures specifically for battery and inverter
systems. Furthermore, receiving approval and compatibility confirmation from major manufacturers
is such an important milestone.

With backing from Fox ESS, SolaX, Duracell, Sunsynk, Solis and GoodWe, installers and
homeowners can have greater confidence when choosing Eco-ESS. It protects their renewable
energy equipment.
