What are the advantages of the built-in lithium battery and external solar panel power supply of the 45MM Tubular Motor?

In high-frequency automation scenarios such as smart shading and electric curtains, the power supply method of the 45MM tubular motor directly affects the system reliability and cost of use. Traditional wired power supply is limited by wiring complexity and energy consumption, while the dual-mode solution of built-in lithium batteries and external solar panels is reshaping industry standards with flexibility and sustainability. How do the complementary advantages of these two technologies release value in different scenarios?
Built-in lithium battery: unfettered intelligent freedom
The lithium battery integrated design of the 45MM tubular motor (usually 18650 battery pack) solves three core pain points:
Ready to use: no need to pre-buried wires, especially suitable for renovation projects such as glass curtain walls and historical buildings, and the installation time is shortened by 70%.
Power-off endurance: Models equipped with a 3000mAh battery can maintain basic operation for more than 30 days (opening and closing twice a day) when the city power is interrupted, avoiding system paralysis caused by sudden power outages.
Energy efficiency optimization: The smart chip monitors the torque load in real time and automatically adjusts the output power. For example, under light load conditions (such as gauze curtains), power consumption can be reduced to 0.8W/time, and a single charge supports more than 600 cycles.
External solar energy: low-carbon practice of sustainable energy
For projects in areas with sufficient sunshine (annual irradiation ≥ 1200kWh/m²), solar power supply solutions show unique advantages:
Off-grid operation: Connecting a 40W flexible solar panel (conversion efficiency ≥ 23%), with an MPPT controller, can reserve 3-5 days of electricity on rainy days, achieving year-round off-grid autonomy.
Cost control: Calculated by opening and closing 4 times a day, the solar solution can save more than 90% of electricity bills within 5 years compared to the mains supply, especially suitable for large townhouses or commercial buildings.
Environmental certification: Meet green building rating standards such as LEED and BREEAM, helping projects obtain policy subsidies or tax incentives.
Scenario-based adaptation: the collaborative logic of dual-mode energy
Residential renovation scenario: lithium battery-dominated + solar energy supplement
In existing buildings, lithium batteries are preferred for power supply (eliminating wiring troubles), and 10W micro solar panels can be optionally used as auxiliary charging sources to extend the battery cycle life from 3 years to 5 years.
New commercial scene: solar energy-dominated + lithium battery emergency
Use the 100W solar array pre-installed on the building facade or roof, with a 5000mAh expansion battery, to achieve self-sufficiency in sunny days and seamless switching on cloudy days, ensuring the stability of 20 high-frequency uses per day.
Extreme climate scenario: dual-mode redundant power supply
For typhoon or blizzard-prone areas, lithium batteries and solar panels can back up each other. When the solar panel is covered with snow, the system automatically switches to battery power supply, and melts the snow through the heating wire (power consumption ≤5W), and gives priority to charging the battery after recovery.
Technical depth of intelligent energy management system
The new generation of 45MM tubular motors achieves a leap in energy efficiency through three technical innovations:
Dynamic priority algorithm: automatically selects the optimal power supply path (solar direct supply → solar charging + battery power → pure battery power) according to the real-time radiation intensity and battery power;
Wireless networking: supports Zigbee 3.0 protocol, intelligently dispatches the remaining power of multiple motors to avoid power shortage of local equipment;
Self-diagnosis system: When dust accumulation on the solar panel is detected (power attenuation > 15%) or battery health < 80%, push cleaning reminders or replacement suggestions to the user APP.
