48 Volt DC Power Distribution System Use Your Renewable Energy First

Nextek’s NPS-1000 delivers power from renewable energy sources such as solar panels, fuel cells, wind generation, and batteries to power a building’s 48 volt DC lighting and other low voltage loads.  Nextek’s Power Module reduces energy costs by using energy from renewable sources first, then fills in with power from the grid or, when the grid is not available, from batteries. This assures higher rate of return on investment and accelerated payback for alternative energy systems.

The NPS-1000 specifically addresses the limitations of conventional power distribution systems by combining the availability of all AC and DC sources of electric power generation, creating a future-compatible electrical system. The NPS-1000 assures power quality through voltage regulation, which eliminates damage from brownouts and power robbing over-voltage situations. A high power factor (>0.99) and very low total harmonic distortion (THD <5%) assure the highest capacity and the cleanest electrical circuits. Power quality enhancements are further provided through the use of the power module’s auxiliary battery storage connection and secondary DC power inputs, providing and uninterruptible and the security offered by multiple power supply support. The patented NPS-1000 achieves its exceptional power efficiency by Direct Coupling® alternative energy directly to the load. The NPS-1000 is designed for exceptional performance with variable intensity power sources such as solar cells and wind generators. Nextek lighting systems are ideal for both small and large installations. Any number of power modules can be installed to accommodate any size of electrical demand. Compact modular construction of the NPS-1000 contributes to easy wiring and flexible installation layouts. Specifications:
