Specific Information for Belgian Customers - Bebat Tax

 

As part of our commitment to regulatory compliance and environmental responsibility in Belgium, we would like to inform our customers that the purchase of a Delong Top LVM15- 15.36 kWhbatteryis subject to a mandatory environmental levy.

A sum of €317.90 excluding VATmust be added for each battery purchased, as a direct contribution to Bebat, the organisation responsible for the management of batteries and accumulators in Belgium. This measure is in accordance with current Belgian environmental legislation.



Important:When purchasing a lithium battery, please add the corresponding product "Bebat Delong LVM15 - 15kWh environmental levy" according to the number of batteries you are ordering. Otherwise, we will recalculate and invoice the amount after the purchase.

This tax applies only to Belgian customers.






FAQ - 15 kVA / 15.36 kWh Three-Phase Solar Kit

1. Is this kit suitable for a house that is completely off-grid? +
Yes, absolutely. This kit is designed to operate in both off-grid (stand-alone) mode and grid-connected mode. The three-phase hybrid inverter can switch between the panels, the batteries and a generator or the public grid to ensure an uninterrupted power supply.
2. What is the difference between Grade A battery cells and others? +
The Grade A cells (CALB/BYD) used in the Delong LVM15 battery represent the highest standard of quality. They guarantee a true capacity matching the label, minimal internal resistance and an extended lifespan (up to 6,500 cycles), whereas lower-grade cells quickly lose efficiency.
3. Why choose a three-phase inverter rather than a single-phase one? +
A three-phase inverter is essential if your electrical installation has three phases (power for industrial machinery, high-powered heat pumps, or large homes). It ensures a balanced load distribution across your network and manages the feed-in of surplus energy optimally.
4. Can I add extra batteries later? +
Yes, the system is fully scalable. The inverter supports the parallel connection of multiple Delong batteries. You can therefore start with 15.36 kWh and increase your storage capacity as your needs or consumption change.
5. What happens if the panels produce more than I consume? +
The surplus is first used to charge your battery. Once the battery is full, the hybrid inverter can either stop production (zero feed-in mode) or feed the surplus into the public grid, depending on your region’s configuration and regulations.
6. What maintenance does this solar kit require? +
Maintenance is minimal. The LiFePO4 battery technology requires no water or electrolyte maintenance. A simple annual clean of the panels with clean water and a visual check of the connectors are sufficient to ensure optimal performance for 25 years.
7. How can I monitor my production in real time? +
The inverter is equipped with advanced connectivity (Wi-Fi). You can track your solar power generation, your battery’s charge status and your household consumption directly on your smartphone or computer via a dedicated app, wherever you are.
8. What is the Bebat tax and does it apply to my project? +
The Bebat environmental levy is a mandatory tax that applies only to customers residing in Belgium. For the 15 kWh battery included in this kit, the amount is €317.90 excluding VAT. It funds the collection and recycling of end-of-life batteries in accordance with Belgian legislation. If you are not a Belgian resident, this tax does not apply to you.
