Targeted Applications

Public parking garages / Parking lots / Parks / Street lights / Garden lights / School campuses / Outdoor signs / Traffic signs / Areas difficult to reach using power cables / Any location which may use lighting or surveillance cameras

For example:
A surveillance application for where power cables cannot reach.

The highly integrated product is an all-in-one photovoltaic energy storage system that comes with a high-efficiency 100Wh solar panel and battery. A built-in solar MPPT charging circuit safely directs constant electrical currents converted by sunlight into a 325W battery. Two built-in LED drivers deliver constant DC power to two 12V/12W outputs for LED lights. A built-in CCTV driver delivers 12V/10W output for a surveillance camera.

Unique technological breakthroughs

ISPB-12 can turn a normal solar panel into a high efficiency solar panel that easily converts even dim light into electricity. This is a leading breakthrough feature in the market. ISPB’s solar panel is embedded with CIGS (copper indium gallium serenades) technology. CIGS has advances on low-temperature deposition.

ISPB-12 integrates many unique circuits into one box. A built-in MPPT charging circuit stabilizes the DC current to charge the battery securely and reliably. A built-in LED driver delivers constant DC power to the LED lights for better performance and longevity. A built-in CCTV driver allows users or system integrators to plug in security cameras or other devices.

ISPB-12 is manageable. For system integrators, Lithium Power, Inc provides development tools to adjust the power usage settings. For example, scheduling when the ISPB will turn on/off or controlling the brightness of the lights.
