Important notice for our customers in Belgium: An environmental contribution of €119.50 excl. VAT will be applied to the purchase of each Sofar Solar BTS 5K lithium battery. More information at the bottom of the page.

Key Advantages

• Complete installation of 25 solar panels of 450 Wp each, enabling significant production.
• 10 kVA three-phase hybrid inverter (Sofar Solar ESI 10K-T1) with 3 MPPTs, capable of managing production, storage, and grid or backup power supply.
• Modular lithium storage (2 "BTS 5K" modules of 5.12 kWh each): stores the energy produced for use at night or during power outages.
• Grid injection possible: this kit mentions "grid injection," meaning that excess production can be fed back into the grid under certain conditions.
• Increased energy independence: reduced electricity bills + possibility to optimize solar production usage.
• Quality and scalable components: high-performance panels (N-Type TOPCon cells) + modular battery.
• Suitable for residential needs or small three-phase commercial/tertiary uses: high power can cover relatively high loads.

Sofar Solar ESI-10K-T1 Three-Phase Hybrid Inverter – 10 kVA for Photovoltaic Installation with Battery

Boost your solar installation with the Sofar Solar ESI-10K-T1 three-phase hybrid inverter – 10 kVA, designed for advanced self-consumption with storage. This high-efficiency model (up to 98.2%) manages photovoltaic production, high-voltage battery charging, and power supply to your residential or commercial grid, while ensuring backup power in case of outages.

Thanks to its 3 MPPTs, it optimizes production even across multiple roof orientations. Its fanless passive cooling ensures silent and durable operation, ideal for residential and commercial installations.

Compatible with a wide range of lithium batteries, it provides a scalable solution to maximize your solar self-consumption and reduce your electricity bills.

Key Features

• Power: 10 kVA three-phase
• 3 MPPTs for optimal efficiency
• Backup function
• Compatible with high-voltage batteries
• Scalable, silent, and high-performance installation
• Ideal solution for production

SOFAR Solar BTS-5K High-Voltage Lithium Battery – 5.12 kWh for Solar Installation with Three-Phase Inverter

Optimize your photovoltaic system with the SOFAR Solar BTS-5K (5.12 kWh) high-voltage battery: a plug-and-play modular solution designed for residential and commercial installations. Thanks to its LiFePO₄ (lithium-iron-phosphate) technology, it ensures an initial capacity of 5.12 kWh, high efficiency, and excellent durability.

Compatible with SOFAR three-phase hybrid inverters (notably HYD and ME series), this battery operates at a nominal voltage of 400 VDC (range 350-435 V) and can be expanded up to ~20 kWh by assembling multiple modules.

Key Features:

• Capacity: 5.12 kWh (per module)
• Nominal voltage: 400 V DC, range 350-435 V
• Efficiency and reliability: lithium-iron-phosphate technology, active cell balancing, modular design
• Easy installation: pre-assembled cables, plug-and-play design, IP65 protection rating (indoor/outdoor installation possible)
• Expandable: up to 4 modules in series for ~20 kWh storage.

Why Choose It?

This battery is ideal for homes or small businesses looking to increase self-consumption, add storage capacity after initial installation, or benefit from backup power. Its modular format allows you to start with 5.12 kWh and add more as needed.

Uses / Needs This Kit Addresses

• A single-family home or building connected in three-phase, with significant electrical equipment: heating, air conditioning, heat pump, workshop, garage, etc.
• A household with high daily consumption or consumption peaks, wishing to reduce grid dependence and optimize self-consumption.
• A situation where orientation and sun exposure are reasonable (well-oriented roof, little shade): this kit works best in good sunlight conditions.
• A user wanting not only to produce but also store part of their energy for use in the evening or on days with lower production.
• A desire to enhance property value, switch to cleaner energy, and in some cases sell excess to the grid (thanks to the "grid injection" function).
• A project where there are plans to potentially increase or expand the installation later (thanks to battery and panel modularity).
• A building operating partially for domestic use but with a "semi-professional" dimension or heavier loads than standard use.

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 Sofar Solar BTS 5K battery is subject to a mandatory environmental contribution.

An amount of €119.50 excl. VAT must be added for each battery purchased, as a direct contribution to Bebat, the organization responsible for battery and accumulator management in Belgium. This measure is in compliance with current Belgian environmental legislation.

Important: When purchasing a lithium battery, please add the corresponding product "Bebat Environmental Contribution Sofar Solar BTS 5K" according to the number of batteries you order. Otherwise, we will recalculate and invoice the amount after purchase.

Here is the reference list and corresponding contribution rates!

This tax only applies to Belgian customers.
