Boost your solar installation with the Sofar Solar ESI-9.9K-T1 three-phase hybrid inverter – 9 kVA, designed for advanced self-consumption with storage. This high-efficiency model (up to 98.2%) manages photovoltaic generation, charges high-voltage batteries and supplies power to your domestic or commercial grid, whilst ensuring a backup power supply in the event of a power cut.
Thanks to its 3 MPPT trackers, it optimises output even across multiple roof orientations. Its fanless passive cooling ensures quiet and durable operation, ideal for residential and commercial installations.
Compatible with a wide range of lithium batteries, it offers a scalable solution to maximise your solar self-consumption and reduce your electricity bill.
Key features

Optimise your photovoltaic system with the SOFAR Solar BTS-5K high-voltage battery (5.12 kWh): a modular plug-and-play solution designed for residential and commercial installations. Thanks to its LiFePO₄ (lithium iron phosphate) technology, it offers an initial capacity of 5.12 kWh, high efficiency and excellent durability.
Compatible with the three-phase hybrid inverters in the SOFAR range (notably HYD and ME), this battery operates at a nominal voltage of 400 VDC (range 350–435 V) and can be scaled up to ~20 kWh by connecting multiple modules.
Key features:
Why choose it?
This battery is ideal for households or small businesses wishing to increase self-consumption, add storage capacity after initial installation, or benefit from a backup power supply. Its modular format allows you to start with 5.12 kWh and then add more as needed.
