The emergence of TKEM for home storage of inverters and batteries

All-in-one energy storage refers to an energy storage solution that integrates battery packs, inverters, BMS, and EMS into a single cabinet. The core value is an “out-of-the-box” zero-configuration experience compared to traditional split systems, which require separate optional inverters, battery packs, and controllers.
Industry data show that in 2024, all-in-one machines will account for 42% of the global home storage market, with an annual growth rate of over 35%. The core driving force is to reduce installation complexity and improve system compatibility. After 2025, all-in-one machines are expected to account for 60% of the home storage market.

• Compatibility risk: 18% mismatch between inverter and battery agreement (European TÜV report).
• High installation cost: split scheme requires an additional US $400-1000 + system integration fee.
• Fragmentation of maintenance: failure needs to be checked by multiple manufacturers, and the average repair time is> 72 hours.

• The EU RED III directive requires residential energy storage systems to have intelligent dispatch interfaces (mandatory in 2026).
• China’s “whole county photovoltaic” policy promotes the penetration rate of integrated optical storage equipment to 67%.

• 50% reduction in size of silicon carbide (SiC) inverter module Smart.
• BMS chip power consumption down to 1/3 of the traditional solution.

• Only 2 interfaces (PV input/load output), 87% fewer connection points than traditional solutions.
• Intelligent self-test: boot automatically identify photovoltaic panel parameters → adaptive MPPT tracking.
• Load access instant matching output waveform (pure sine wave> 99.9%).
• Mobile management: APP remote monitoring + OTA upgrade, fault self-diagnosis accuracy> 95%.

The measurement is based on a 5KWh system, including PV adapter components.

Double cavity isolation design:

• Power compartment (battery + inverter) + IP67 protection/independent air duct of heat dissipation compartment → electromagnetic interference <15dB (EU RED directive limit 30dB)
• Module quick release technology: failure module replacement <10 minutes (industry standard ≥ 1 hour)

• Full inspection process: cell entry → ultrasonic flaw detection → internal resistance classification (0.05 mΩ) → 72 hours aging → self-discharge sorting (>5mV/day elimination) → A + class cell (EVE)
• Output result: battery pack dispersion <0.03%(industry average 0.5%)
• Product A cells use sensor devices and intelligent algorithms to achieve millisecond-level defect detection and elimination. The terminal positioning algorithm ensures accurate alignment, reduces manual production line intervention by 92%, ensures subsequent welding pass rate of more than 99.99, and extends battery pack life by 50%

• The innovation adopts the stress balance technology of aviation grade aluminum alloy + stainless steel composite module, which makes the stress distribution on the battery unit reach 98% uniformity. This reduces the cycle expansion by more than 50%, completely eliminating the expansion problems that occur in conventional processes. Its unique directional heat conduction channel design effectively minimizes the temperature difference inside the battery.
• Performance improvement: low temperature -25 ℃ discharge retention rate 92% (traditional process 76%)

• Equipped with a high-power pulse laser generator, the welding is completed instantly to ensure that the penetration depth and width of the welding point meet the standards, the welding strength is increased by 40%, the heat of fast charging is reduced by 30%, and the conductivity efficiency is increased by 15%. With metallographic testing instruments, the welding quality parameters can be fed back in real time to ensure zero hidden dangers of welding quality and eliminate false welding.

• Support: Users can remotely monitor in real time through the cloud platform: SOC (remaining capacity), SOH (health) data cloud synchronization, fault response time <10 minutes.
• Blockchain power trading: compatible with P2P energy sharing, increasing PV spontaneous generation rate to 85%.
• Remote upgrade: firmware online update function reduces operation and maintenance costs by 40%

All series are equipped with Type-C fast charging/RV port/emergency start function as standard.
