A traditional building will distribute AC power to individual loads, at which point it must be converted to DC power, a process called rectifying. Using a high efficiency rectifier at each load source is not economically feasible. Nextek's PSM avoids this issue with its integrated high-efficiency rectifier that converts up to 1600 watts with minimal power loss to DC which is then distributed through 16 channels.
Solar panels inherently produce DC power. A normal solar power system will invert this DC power to AC for distribution purposes. The power is then distributed throughout the building to each of the loads, where it is converted back to DC. This DC-AC-DC process can be incredibly inefficient. Nextek bypasses these steps by simply taking the solar array's DC power, stepping the voltage down to 24V, and distributing it to loads.
On-Site Battery Backup
Similar to solar power, battery backup systems run on DC. In a traditional AC system, an DC-AC-DC conversion would be necessary to use their power. Nextek's PSM takes DC battery power, and distributes it directly to DC loads, avoiding more unnecessary conversions. Similar to the gains realized with solar power, Nextek's system is much more efficient at utilizing battery power than a traditional AC system.
