In Belgium, the distributor of home batteries has a take-back obligation. This means that that distributor takes charge of collecting batteries for recycling and undertakes to accept returned batteries from end customers.  The cost of this processing is charged to the consumer upon purchase of a home battery. Of course, you can only return batteries to the original distributor, i.e. not to any distributor.

Your battery was registered at the time of sale and the 'recycling' contribution has already been set aside to bear this cost at the end of the battery's life. So always ask your installer what the origin of your home battery is, and whether the recycling surcharge is included in the offer. 

Are you an installer? Then make sure your end customer is well informed about where the battery was initially purchased, and provide sufficient information about recycling. At Allimex, we charge this cost as an extra 'item' on the invoice. 

When buying a home battery in belgium, there is an additional charge for the final recycling of the battery when it is end of life.  In exchange, you can return your end-of-life battery to the original distributor. The latter in turn will arrange professional collection of batteries, which can then be recycled.

This also applies to all batteries purchased from Allimex Green Power. As an importer, Allimex Green Power has a take-back obligation. Contact your installer to find out the origin of your battery and whether the recycling fee has already been charged. 

We register all batteries before they go to the customer, so we can perfectly trace whether your battery really originates from us.

It is best to contact your installer first.  He will check what the problem is and which guarantee conditions are valid for your specific case. In case the battery cannot be repaired and is still under guarantee, it will be exchanged according to the guarantee conditions. 

As an importer, Allimex Green Power has a take-back obligation. This means that when you buy a domestic battery, you will be charged an additional cost for the eventual recycling of the battery when it is 'end of life' . This applies to all batteries purchased from Allimex Green Power. Contact your installer to find out the origin of your battery and whether the recycling battery has already been charged.

The inverter is one of the most important parts of a home battery system. It is connected to the electricity cabinet, the solar panels and optionally to a home battery. Through the electricity box, the inverter ensures that the electricity produced by your solar panels or coming from your home battery is available to use in your home. Through the electricity box, the inverter can also store electricity from the solar panels or possibly from the grid in the battery. The whole system is fully automated.

Sadly, no. If you already have a solar system, you should first check whether your inverter is “battery-ready”.  If you don’t have a “bidirectional” inverter, you can choose to install an additional inverter or replace your current inverter with a hybrid one.

Which home battery is best for you depends on your energy consumption and the size of your solar system. How much capacity your home battery should have depends on your consumption profile, your inverter, the appliances you use at home and how much power you can generate locally. Installing your battery and PV panels at the same time is a great way to make sure that your system is configured optimally.

Preferably not, and certainly not in the rain or anywhere where the battery can be exposed to water. Large temperature fluctuations are also not recommended, as condensation can form inside the inverter housing.

The payback period for a home battery system depends on your specific situation. Important factors to consider include:

• Do you already have solar panels?
• What VAT rate applies to you? 6% or 21%?
• What do you currently pay for your electricity?
• Are you entitled to grants and are you interested in applying for one?
• The quality of your preferred battery system.

Typically, we see payback periods of 8 to 10 years.

However, home batteries have a wide range of benefits, so payback time isn’t the only metric to look at.

• With a home battery, you won’t be affected by future increases in electricity rates as much. A valid argument if you consider that electricity rates have increased by an average of 6% a year over the past 10 years!
• Besides, installing a home battery means doing your bit to reduce carbon emissions and counteract global warming. Rather than contributing to the problem, you’ll become part of the solution!

This isn’t recommended. The battery is modular, which means it can be expanded in the future. This won’t be as easy if you’ve wall-mounted your system.  Besides, a single battery module weighs about 30 kilograms.

For the FIREFLY, the max. distance between the inverter connector and the battery connector is approximately 6 metres, while it’s about 10 metres for the LUNA. This minimises losses and stops the cable getting too hot.

As long as the battery is active, your PV panels will stay on and power the circuits wired to the EPS output, as well as charging the battery in case of overproduction.

Our Firefly can be discharged down to 10%. Discharging the battery by 90% and then recharging it only constitutes 1 cycle. With our residual capacity of 85% after 5,000 to 6,000 cycles, this amounts to a useful life of around 15 years. The battery’s overall lifespan, with a residual capacity of 70%, is probably around 20 years.

The FIREFLY is not actively cooled, as it does not need a fan thanks to its robust design and high efficiency.

Yes, within a few months of purchase and installation, the battery can be easily modularised into blocks of 3.6 kWh to a total of 25.2 kWh. If you want to expand after a few years, we’ll remove your used batteries and refund you their residual value. If possible, we’ll expand your current battery with a used battery with the same number of operating hours to prevent internal currents and efficiency loss.

Any electrical device or battery can catch fire in the event of a short circuit or technical defect.

• The designers of the FIREFLY opted for LiFePO4 battery technology to mitigate this risk and make sure that the battery can simply be extinguished if it does catch fire (unlike Li-ion batteries).
• Thanks to the battery’s aluminium housing, dedicated pressure relief valves for each module, 240 Wh modules (which means you only need 4 modules for 1 kWh storage) and sound temperature and voltage monitoring, the FIREFLY is a very safe system.

It usually won’t in Belgium, but you are obliged to notify your insurer.

You could, but it’s not a financially interesting option. It would require a major investment, and you still wouldn’t be able to carry over solar energy from summer to winter.

The Firefly has a 3kW Electricity Power Supply output on its inverter, and if your installer wired this output to several circuits in your home, these circuits can remain live in the event of a power cut. Within 10 msec, this EPS output will switch from the grid to the battery in the event of an outage.

We offer a 10-year warranty on the entire system.

Certainly. All our systems are Synergrid-approved, which is just about the strictest scheme in Europe. From 2021, the Netherlands will probably also adopt the Synergrid label as a requirement.

You do not need to reserve capacity for the backup function to work. In the event of a grid failure, the remaining battery capacity will serve as a backup. If there is still PV power stored in the hybrid inverter, it will continue to supply energy whilst storing any excess energy in the battery.

You can wire our system in parallel to existing systems consisting of PV panels and an inverter. However, you will not be able to see how much energy is generated and used by the PV system in the app.

They do not take the generated PV power into account, but do take grid injection into account. The Home module takes grid injection by PV panels in Eco mode into account. This will prompt the home to switch to a lower charging setting (6A) and accommodate for the injection detected by the phase clip.

All our systems are available with load balancing, except the Mobile. This application can be configured in various different ways at the installer’s discretion, depending on the project in question.

Yes, all our industrial charging stations can be opened to the public, so that users can also scan public badges to charge their vehicles. Please note that this is only possible if the stations are made publicly accessible.

When installing multiple charging stations at a private residence, we will look at incoming power. Depending on the situation, we’ll opt for several separate wall boxes (without a fixed cable) or several Home modules (with a fixed cable).

The Home has an internal 6 mA DC breaker. It requires a type A differential (40A 30mA) and a 32A circuit breaker. Our Advanced and Cluster ranges require the same breakers, though they must be three-phase with a 40A 30mA type B (!) differential and a 32A circuit breaker.

This is possible, but due to Powerdale's warranty conditions, it will void your current warranty.

Please note that type 2 systems only support type 2.

The fleet manager can manage all activities of users or drivers in the company on a paid platform. There are two options:

• Nexxtmove Flex: EUR 6 per month per station.
• Nexxtmove Business: one-off fee of EUR 300 per station.

An inverter converts the direct current generated by PV panels into alternating current.

Panels are made from an element called silicon. Silicon crystals come as POLY and MONO cells.

POLY cells

• Cells composed of several small residual pieces.

MONO cells

• Cells that come from the same batch of silicon and that have therefore not been mixed.

Used to denote the Wattage of a system.

• 1 kWp = 1000Wp
