Here’s our newest product, the MicroNexus Power Center!

We are excited to be sending several hundred complete, pre-integrated 12V PV systems featuring the MicroNexus to schools in Tanzania in the new few months.

The MicroNexus is a circuit protection and wiring integration enclosure that becomes the heart of a small off-grid solar PV system. Connect your solar panels, attach your batteries, and you’re ready to power up! The MicroNexus handles the control of solar PV charging of the batteries, and distributed the flow of current from the battery out to your lights and appliances. We pre-wire the Nexus for ease of installation under remote field conditions or by DIY non-professional installers. Each MicroNexus contains a charge controller (5-30 Amp), a battery meter, room for up to six panel-mount circuit breakers (comes with 3 DC breakers standard), two insulated busbars for DC load distribution, a ground (earth) busbar, and has a variety of knock-outs for easy conduit or “trunking” access.

We designed the MicroNexus to power low-power DC computer labs in East African schools. But its remarkable versatility makes it an excellent choice for a wide variety of off-grid applications. Add an inverter, and run your AC power loads– with up to a 100 Amp DC breaker installed. Need more charging power? The MicroNexus can scale up for PV charge controllers up to 80 Amps or multiple controllers in parallel.

The unit can be purchased alone, or as part of a complete pre-wired PV system, including modules, batteries and all the required interconnections and balance of systems hardware. Give us a call — we’ll custom design and build a MicroNexus system to meet your needs.

As with all SolarNexus products, we source from the best in the business and stand behind our products with a lifetime limited warranted. Creating happy off-grid customers is why we’re in business!

The Solar Nexus Power Center is designed to provide quiet, reliable electric power for off-grid schools, clinics, offices and homes in rural areas of the developing world.

With the addition of a properly sized photovoltaic (PV) array and deep-cycle battery, the SolarNexus is the central wiring hub of a complete off-grid solar electric system.

Inside the SolarNexus are all the high quality electronics necessary to convert the energy generated by the solar PV panels (or any other source of renewable energy) into power that is stored in batteries for later use.   Electric output is both sinewave AC power and 12 Volt DC power.  We utilize UL-recognized circuit breakers and wiring interconnection hardware.

The SolarNexus power center is designed for permanent indoor installation. Detailed instructions, training and support are provided to ensure successful installations.

By pre-engineering these systems, we bring the time-tested quality of North American off-grid solar installations to areas of the world where such systems are hard to come by.

In April of 2010 we shipped 30 complete SolarNexus systems -- including PV panels and deep cycle batteries -- to Tanzania for a project run by the U.K. based charity SolarAid. The systems will provide lighting and power to schools far beyond the reach of the electricity grid, replacing smoky and dangerous kerosene lanterns with efficient compact fluorescent light and enabling the schools to serve more people in the local areas.

In May of 2010, SNI founder Eric Youngren traveled to Tanzania to assist in the training of local installation crews. One goal of Solar Nexus International is to improve the knowledge, skills and capacity of solar installers in the developing world.

SolarNexus power centers are sold as part of a complete package, shown here. The package includes PV panels, deep cycle batteries, mounting hardware, code-compliant wiring, and instructions.

Please contact us if you are interested in purchasing SolarNexus systems.

The SolarNexus model pictured has a continuous power rating of 300 Watts. Larger models are available.
