Home BESS

The most compact residential battery in the industry.

Welcome to the future of home energy management with the YES-EU Home BESS, a residential energy storage system designed to safely and efficiently power your life. Whether you want to maximize solar self-consumption or leverage dynamic electricity tariffs and Virtual Power Plants (VPP), this system delivers exceptional, long-lasting value.

Compact, scalable, long-lasting.

  • 6–64 kWh Per stack
  • 15,000 Cycles (Kunlun cell)
  • 15-year Extended warranty
  • IP66 Indoor or outdoor
Why Home BESS

Engineered for modern households.

  • Compact & effortless setup

    The industry's most compact battery. A high-density design (35% above average) and ultra-lightweight (<30 kg) modules allow fast, hassle-free, one-person installation.

  • Limitless scalability

    Seamlessly expand from 6.0 kWh to 64 kWh per stack, with a universal 80V–1000V operating range and support for up to 10 parallel systems for powerful microgrids.

  • Unmatched lifespan & ROI

    Engineered to maximize profits from dynamic tariffs and Virtual Power Plants, delivering 15,000 cycles and backed by a 15-year extended warranty.

  • Bulletproof resilience

    Built for the harshest environments with an IP66 rating that blocks rainstorms and operates flawlessly from -20°C winters to 50°C summers.

  • Instant upgrades

    Advanced passive balancing automatically aligns module charges (~10% SOC/day), letting installers stack new batteries onto existing systems, saving 3 to 4 hours of labor.

Using scenarios

Built for real homes.

Tight-space installation

Volumetric energy density 35% above the industry average. A standard 4-module system (12–13 kWh) stands just 0.74–0.75 m tall, with hidden wiring and no decorative panels for a clean look in a narrow garage or small closet.

Effortless upgrades (easy retrofit)

Buy an EV or add a heat pump later and need more energy? Passive balancing (~10% SOC/day) lets a technician bring a new 26.5 kg module, stack it on your existing system, and leave, saving 3 to 4 hours of labor (roughly €180–240).

Surviving extreme weather

A die-cast aluminium enclosure, IP66-rated with 72-hour flood resilience. Operates down to -20°C and discharges without an internal heater, keeping your home powered through freezing winter grid outages.

Dynamic tariffs

8,000 cycles with standard cells and up to 15,000 with premium Kunlun cells, so you can trade energy daily without voiding the warranty. Even at one cycle a day, up to €1,764 in additional savings over 10 years versus competitors, while retaining 80% of battery health.

Peace of mind

Inherently stable LFP chemistry with an ultra-low failure rate (<1 PPB), having passed nail-penetration and hot-box abuse tests. The battery pack operates with zero Wi-Fi, eliminating cybersecurity and hacking concerns.

Savings on initial installation

Every component, including modules, weighs under 30 kg (each module 26.5 kg) with integrated handles, so a single installer can carry and click them together, saving roughly €60–95 per hour. Over the lifespan, reduced logistics, installation and maintenance can save up to €154–194 per kWh.

Advantages for installers

Faster, cheaper, simpler to deploy.

One-person installation

Every component, including the 26.5 kg battery modules, weighs under 30 kg with integrated handles, enabling a single installer to set up the entire system without a helper, saving at least €300 a day (€60–95 per hour).

Zero-friction assembly

No side screws between modules, no decorative panels to attach, and a hidden wiring design make the physical installation exceptionally quick, clean and straightforward.

Stack and leave retrofitting

Passive balancing of ~10% SOC per day lets installers stack a new module on top and leave, saving 3 to 4 hours of on-site SOC alignment (roughly €180–240).

Simplified training & procurement

A one-SKU-fits-all solution for residential and commercial (C&I) setups. Because the installation mode is identical for both, it streamlines procurement and installer training.

Reduced logistics & storage costs

Compact 600×400 mm modules are fully compatible with standard Euro pallets, cutting storage and logistics costs by over 20% (roughly €2.55–3 per kWh).

Highly versatile placement

A small footprint needing only 10 cm of wall clearance, plus IP66 weatherproofing and optional wall mounting, for indoor, outdoor or tight, low-clearance placement.

Configurations from 2 to 19 modules in series (44.8V / 75.2Ah / 3.3kWh module, 14S1P; max 4 stacks in parallel). Also available with 63.6Ah (3.2kWh) and 52Ah (2.99kWh) cells.
