SunBlazer IV

Home / Technology / SunBlazer IV

The SunBlazer IV is a next-generation product that is an easy-to-install PV solar-based community charging station.

The next-generation product in the SunBlazer series, the IEEE Smart Village SunBlazer IV, has scalable features designed to provide reliable sustainable energy solutions to off-grid communities around the world.

IEEE Smart Village aims to relate across boundaries, incubate new designs with community input, demonstrate sustainable local market enterprise, and educate through linked learning communities.

These goals draw principally on the work of IEEE engineers and partner educators to develop synergistic and holistic community solutions. SunBlazer IV aims to service smaller villages cost-effectively at the same time introducing a simple scaling model with added reliability through redundancy. Numbers of systems can be deployed throughout a community to provide many kilowatts of power as the community grows its demands.

Simultaneously, a reciprocal learning training and education model will enrich the knowledge and experience of students, engineers, and development practitioners globally.

How it Works

SunBlazer IV is a mobile solar 1,800W to 3,600W base station including 100-200Ah at 24V station batteries and portable battery kits (PBKs) for home lighting. Each PBK has an auxiliary outlet for other DC powered devices in the home such as cellphones or small entertainment devices.

Assuming an average three to four-day return for recharge and two charging shifts for the 12Ah PBK batteries, with 6 chargers the basic unit with two four-hour charging shifts will support 36 home lighting systems of 2-4W LED bulbs. With 12 chargers (12-pack) it can support 60 12Ah units.

The solar panels are held in a stand-alone A-frame with adjustable solar angle. The heavy duty steel box containing the electronics can rest under the frame, or on a concrete pad nearby. The assembly needs protection by a security fence, or alternatively the box could go indoors and the panels mounted on a roof.

All PBKs and stations will contain a monitoring and telemetry feature to record by battery serial number/lessee every time a PBK is charged.

For larger home or base loads, multiple SunBlazer IV’s with expansion capacity can be deployed.
