Converting d.c. from the solar panels to a.c.
A well-designed solar electric system, backed by a husky battery bank, has
inherently high reliability on the d.c. side. However, the point at which
power is converted to a.c., which is the responsibility of the inverters, is a
potential weak point. Sudden, unpredictable overloads can cause the inverter to
shut down. The current inverter subsystem, our third-generation of
inverters, is visible as the black panels in the relay rack at the center of
