Batteria Domestica in Garage or Shed: Practical Placement Advice

Garage and shed: popular batteria locations

The most popular placement location for a batteria domestica nei Paesi Bassi is the garage or shed. This is understandable: there's space, the batteria isn't visible in the living area, and the installatore has easy access. Tuttavia, the garage and shed also impose specific requirements on the system — requirements that aren't always communicated at the time of purchase.

In this article, we provide you with complete and practical placement advice, including sicurezza antincendio regulations, temperature requirements, and structural aspects you need to know.

Requirements for the placement location

A batteria domestica in the garage or shed requires a location that meets the following minimum requirements:

• Temperature range: most batterie LFP operate optimally between -10°C and 45°C. At temperatures below 0°C, performance decreases, and in extreme cold (<-20°C), the batteria may shut itself down.
• Ventilation: although batterie LFP do not emit gases during normal use, a ventilated space is required as a sicurezza antincendio measure. An opening of at least 500 cm² is sufficient for most installations.
• Moisture protection: the batteria must not be exposed to direct rain or condensation. IP55-certified systems are resistant to indirect humidity but should not be placed outdoors.
• Accessibility: a minimum of 30 cm free space at the front and bottom for service access and heat dissipation.
• Flat, stable surface: for wall mounting, the wall must be able to support at least 300 kg per m² for heavier systems.

Garage vs shed: the key differences

The choice between garage and shed depends on the structural properties of the space:

Attached garage (to the home)

An attached garage is thermally the most stable: the temperature fluctuates less than in a detached shed. The cable distance to the meter cupboard and pannelli solari is usually shorter, which saves costi di installazione. Disadvantage: in case of fire, the flames have direct access to the home. Always use a fire-resistant cladding panel (REI 60) on the wall side adjacent to the living area.

Detached garage or shed

A detached garage or shed offers greater sicurezza antincendio distance from the home. Disadvantage: temperature variations are greater (cold in winter, hot in summer). During very warm summers, uninsulated sheds can reach temperatures of 50°C+ — above the temperatura di esercizio of most batterie. Consider insulation or a ventilation system.

Outdoor installazione

Some produttori offer IP65 outdoor-certified batterie that can be placed outside. Tuttavia, this is only possible in a special outdoor cabinet and requires protection from direct sunlight. Always check the IP rating and temperature specifications of the specific model.

Installazione requirements by system type

Installazione requirements vary by system type:

Sicurezza antincendio regulations for the garage

The Dutch fire service and Building Decree set requirements for installazione della batterias in the garage:

• REI 60 fire resistance: the separation between garage and living space must be fire-resistant for at least 60 minutes (legally required for attached garages)
• Smoke detector and CO₂ detector: install a combined smoke detector and CO₂ detector in the garage, linked to your home alarm
• Class A fire extinguisher: ensure a CO₂ fire extinguisher (minimum 5 kg) is placed near the batteria. Do not use water extinguishers on live electrical equipment

Conclusion: a well-considered placement choice

The garage or shed is an excellent location for a batteria domestica, provided you account for temperature, ventilation, and sicurezza antincendio requirements. Always have the location assessed by the installatore before purchase — they can foresee problems that are expensive to resolve after installazione.
