If you want to install multiple home batteries, you need to pay close attention to the technical requirements. Consider the right cabling, suitable inverters, sufficient space, and additional technical conditions. In this blog, you'll discover step by step what you need to install home batteries safely and efficiently. Whether you are a business, agricultural entrepreneur, or individual: good preparation prevents high costs and maximizes the benefits of your investment.

The role of cabling for multiple home batteries

Cabling is essential when connecting multiple home batteries. Incorrect cables can cause energy loss, malfunctions, or even dangerous situations. Therefore, strict requirements apply to cable thickness, length, and connections.

Things to pay attention to:

• Use cables with enough capacity to handle power surges.

• Keep the cable length as short as possible to minimize energy loss.

• Always choose certified cabling that can withstand high temperatures and prolonged load.

• Ensure good grounding to minimize safety risks.

A specialist will prepare a cable plan in advance that includes the total system power and expected load. This ensures your home batteries function efficiently and safely.

Inverters: indispensable for multiple home batteries

Inverters play a key role when you want to install multiple batteries. They ensure that the stored energy is made usable for the power grid or for direct use within your own installation.

Important points to consider:

• Use an inverter suitable for parallel battery setups.

• Pay attention to the maximum power and efficiency of the inverter.

• Check whether the inverter is suitable for the battery technology you are using (e.g., lithium-ion or LFP).

Sometimes multiple inverters are needed, depending on the number of batteries and the desired flexibility. A good configuration prevents malfunctions and optimizes the performance of your home batteries.

How much space do you need for multiple home batteries?

The physical space needed to place multiple home batteries is often underestimated. Besides the dimensions of the batteries themselves, you also need to consider ventilation, maintenance, and fire safety.

Key aspects:

• Ensure a dry, well-ventilated space.

• Maintain a minimum of 30 centimeters distance around each battery for heat dissipation.

• Preferably install batteries in a place with stable temperatures, such as a technical room or separate battery room.

• Avoid locations with direct sunlight or extreme cold.

With sufficient space, you prevent overheating and extend the lifespan of your home batteries.

Technical conditions and regulations

When installing multiple home batteries, you must consider laws and regulations. Think about safety requirements, building permits, and standards for electrical installations.

Examples of technical conditions:

• Installation must comply with the NEN 1010 standard for electrical safety.

• A certified installer is often required for larger systems.

• Fire safety measures, such as smoke detectors and special extinguishing systems, may be required.

• You may need to report to your network operator due to feedback or increased capacity.

Being well-prepared for these requirements prevents delays or fines and ensures reliable operation of your home batteries.

The benefits of a professional installation

Although it may be tempting to start yourself, hiring a professional installer is the best choice for multiple home batteries. They know exactly what requirements apply, can offer custom solutions, and ensure everything is connected safely and future-proof.

Benefits of professional installation:

• Faster installation thanks to experience and the right tools.

• Complete inspection and certification.

• Access to warranties and service contracts.

• Advice on optimization and integration with existing systems.

This way you get the most out of your investment in home batteries.

Frequently asked questions about installation requirements for multiple home batteries

Do I need to create a separate space for multiple home batteries?
Yes, a separate, well-ventilated, and dry space is strongly recommended for safety and optimal operation.

Can I combine multiple home batteries with one inverter?
Yes, provided the inverter is suitable for parallel battery setups. Sometimes multiple inverters are more efficient.

Which cables are suitable for multiple home batteries?
Use thick, certified cables with sufficient capacity and protection against high temperatures.

Do I need a permit to install multiple home batteries?
In many cases not, but for large systems or business applications, a notification or permit may be required.

Should I inform my network operator?
Yes, for large installations or increased feedback, a notification or adjustment of your connection may be required.

What happens if I have insufficient space for the batteries?
Insufficient space can lead to overheating, reduced performance, and faster wear of the batteries.

Are there special fire safety requirements for multiple batteries?
Yes, especially for larger installations, additional requirements apply, such as smoke detection and sometimes extinguishing systems.
