The Deye 15 kW hybrid inverter (SUN-15K-SG05LP3-EU-SM2) is the ultimate power solution for large homes and commercial three-phase installations. Capable of handling up to 19,500 W of photovoltaic power, it enables extensive energy self-sufficiency by combining large-scale solar generation with battery storage.
The technological breakthrough of this model lies in its AI-powered Deye Copilot system. This intelligent brain analyses your consumption data, weather forecasts and grid tariffs in real time to optimise every watt produced. The AI anticipates your needs, intelligently manages battery charging and discharging, and maximises your savings without any effort on your part.
Unique on the market for this power range, it remains compatible with low-voltage batteries (48V), offering unrivalled flexibility and installation safety. With its ultra-fast backupfunction (4ms),it guarantees total service continuity, even on the most demanding grids.
Key benefits:
The Leapton EL-A16 battery has established itself as the benchmark for high-capacity storage in modern photovoltaic installations. Designed to offer maximum energy density in a compact format, it utilises LiFePO4 technology to ensure complete thermal safety. Its exceptional robustness and 16 kWh capacity make it the ideal partner for high-power hybrid inverters, delivering uncompromising energy autonomy.
Key features and specifications:
With the EL-A16, Leapton offers a durable storage solution capable of handling high charge and discharge currents (150A), thereby ensuring the longevity of your solar investment.

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 Leapton EL-A16 battery is subject to a mandatory environmental levy.
A sum of€346.80 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 Leapton EL-A16 Environmental Levy – 16 kWh" 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.
