What EFT-Systems does
EFT-Systems GmbH is a German energy equipment distribution and lifecycle-services company founded in 2015 and headquartered at Bruchtannenstraße 28, 63801 Kleinostheim, Bavaria. The company is the official and exclusive European service partner of BYD BatteryBox, acting as the primary contact point for all BatteryBox installers across the continent. Its operations cover roughly 12 European countries with local teams operating in 8 languages and serve a network of 400+ certified installers who purchase and install BYD's residential and commercial energy storage systems for end customers in Germany, the UK, Italy, the Netherlands, Poland, France, Spain, Austria, Lithuania, Sweden, Switzerland, and Portugal.
The product portfolio distributed and serviced by EFT-Systems spans BYD's Battery-Box family — HVB (high-voltage, 4-256 kWh), HVE (high-voltage integrated battery-plus-inverter, 6.4-70.92 kWh at 140 mm form factor), HVS+ and HVM+ (high-voltage modular, 5.1-66.2 kWh, VDE 2510-50 certified), Premium LVS and Premium LVL (low-voltage up to 983 kWh) — together with Power-Box SH3-6K (single-phase 3-6 kW) and TH5-15K (three-phase 5-15 kW, 98.2% max efficiency) hybrid inverters. All cells are BYD's cobalt-free Lithium Iron Phosphate (LFP) Blade cells in Cell To Pack configuration, with up to 15-year warranty on HVB products. EFT-Systems does not manufacture the cells or inverters; it monetizes the relationship through distribution, training, technical support, ticketing via the BePartner portal, event programming, and end-of-life battery takeback as BYD's appointed producer extended responsibility agent under EU Battery Directive 2006/66/EC.
The business model is B2B2B channel-partner driven. Revenue is generated through hardware sales to certified installers (placed via email or telephone with prepayment or PayPal), professional services revenue from training, technical support, and after-sales, and managed services revenue from European logistics and end-of-life battery management on BYD's behalf. Pricing is not publicly disclosed. The company is a privately held German GmbH with no external institutional investors identified, 70+ employees, and is led by Managing Director Juan Carlos Alonso.
