Abstract: A group of solar power stations with inverters are adjusted in order to achieve optimum power output in accordance with maximum power-point tracking (MPPT). The MPPT data is used to perform adjustments. Power measurement factors, including Maximum Power Points (MPPs) are established to represent a bus-voltage setting that produces the maximum power output from an individual photovoltaic panel. These settings are established for the group so as to optimize power output under a variety of operating conditions.

Abstract: In high-current electrical devices protected by fuses, additional performance data besides whether or not a fuse is blown is useful for diagnostics, repair, and preventing emerging failures from reaching a level that damages the device. An intelligent fuse-holder includes a built-in current sensor. The current sensor signals are passed through an A/D converter and analyzed by a microcontroller. Through an interface, a user can program the fuse-holder to periodically degauss the current sensor coil to improve performance or turn the sensor power off to conserve power. The user may also control various I/O signals carrying information about the fuse, the intelligent electronics, or the host board on which the fuse-holder is mounted.
