DEYE 3.6 kW hybrid inverter + 5.12 kWh LiFePO4 battery: this pack is ideal for adding intelligent energy management to an existing or new photovoltaic installation. The hybrid inverter manages solar production, power supply for appliances, and battery charging/discharging to better optimize your kWh daily, with the option to sell back the surplus depending on your configuration.
Key benefits: the Leapton LiFePO4 5.12 kWh battery (IP65 + integrated heating) stores energy produced during the day to release it when production drops, in the evening and at night, increasing self-consumption and reducing reliance on grid energy.
Why choose this pack? A compact and scalable solution, durable lithium technology, 48V compatibility, battery wiring included (2x25mm² – 2 m), and XVB cables provided for a clean integration.
Customization: possibility to adapt storage capacity, add batteries, or select a hybrid inverter with a different power rating according to your needs. Our Wattuneed advisors provide a personalized study (consumption profile, goals, site constraints).
Quote & support: contact us to validate compatibility with your installation and receive a tailor-made offer.
