Achieving Approx. One Week of Operation Even in Cloudy Weather! Latest 'Portable Solar Power System' Launched

Assist You Inc. (Headquarters: Miyazaki City, Miyazaki Prefecture; President and Representative Director: Yuki Obata) has developed and launched the 'Portable Solar Power System,' a state-of-the-art outdoor power unit capable of supplying stable power even in harsh outdoor environments, effective May 25, 2026.

This system is an off-grid power source combining high-efficiency solar panels with a large-capacity, high-safety lithium iron phosphate battery. It solves challenges in locations where power supply was previously difficult to secure—such as emergency power during disasters, outdoor monitoring systems, events, and temporary facilities—without the need for construction.

Development Background In recent years, the progress of DX (Digital Transformation) has led to a surge in demand for outdoor security cameras and data collection via IoT devices. However, significant barriers have included locations where power installation is costly and time-consuming, temporary event/construction sites where fixed power is inefficient, and environments with unstable power supply risks like disasters. Under the concept of 'Sustainable power for every location,' Assist You developed this system, balancing mobility and sustainability.

Product Features 1. Autonomous power via 150W high-efficiency solar generation Equipped with high-efficiency panels as standard, the system operates equipment while storing excess power in the battery, ensuring continuous operation even at night or in bad weather.

2. Long-lasting power with high-capacity battery Equipped with two lithium iron phosphate batteries (total approx. 3584Wh), known for safety and long cycle life. When fully charged, it can operate low-power devices (approx. 15W) for about a week (7 days) without solar input. - Smartphone (approx. 6W/unit) 10-unit simultaneous charge: approx. 40 hours - 2 Notebook PCs (approx. 50W/unit): approx. 24 hours - Low-power device (15W or less, 1 unit): approx. 8 days

3. AC100V output support Built-in 1000W pure sine wave inverter allows the safe use of standard AC100V devices like PCs and precision equipment.

4. 'Portable' design for immediate deployment Major components are housed in a rugged, waterproof/dustproof caster case. It can be offloaded from a vehicle and put into operation immediately without heavy machinery or complex installation.

Intended Uses - Outdoor security camera systems - Emergency power during disasters - Construction sites/temporary facilities - Outdoor events - Mountainous regions/agricultural equipment - Infrastructure inspection/monitoring devices

Future Developments Assist You intends to expand this system not just as a power unit, but as a foundation for outdoor monitoring and safety solutions, including packaging with AI cameras/IoT devices, strengthening partnerships with municipalities, and expanding the product lineup.
