5KWh energy storage inverters have diversified styles, including integrated hybrid inverters, split grid-tied inverters and stackable energy storage inverters, covering household energy storage, emergency backup and small industrial and commercial power supply scenarios. The integrated model with built-in MPPT photovoltaic controller is compact and easy to install; the split model has strong scalability for high-power combined systems; the stackable model supports free capacity expansion for stepwise power demand. All models adopt IP65 waterproof and dustproof design for indoor and outdoor installation. With optimized hardware, it has a 15-year design lifespan, 26,000 battery cycles and 98% charge-discharge conversion rate, featuring high efficiency, energy saving and low failure rate in long-term use.
