incandescent lights are also wired in series to serve as dining room overhead lighting. I questioned Maggie about why the lights were wired in series, since this would cause both bulbs to go off if one burned out. The installer had chosen to wire the 24 volt system like this because it was easier to obtain 12 volt bulbs. The third DC circuit is wired to a Voltcraft SPA-5, 24 to 12 VDC voltage converter so that it can power the 12 volt radio telephone answering machine. Unlike the DC circuits,...

The 12 volt panels were mounted on the south face of the second story roof and wired in series and parallel to produce 8.4 amps at 24 volts. To avoid penetrations in the aging roof, the steel mounting channels were seated in eight, basketball-sized concrete lumps attached to the roof. The two, 33 mm2 2 AWG PV leads are outdoor rated and run without conduit for about 20 meters 66 ft. ,...

So we have plenty of sunshine available in the summer, but we need to catch every possible ray in the winter. Solar collectors produce the most energy when their collection surfaces are perpendicular to the sun. Tilting collectors to match a particular...

SMA agrees with me that an external fan should be offered for people who are in hot climates or would like their inverters in an indoor location like a garage . A simple box fan that could be mounted on top of the inverter's heat sink is a needed accessory. The SB2500 does not use energy at night. It has a relay that disconnects the unit completely from the AC lines when there is no DC input from the array. The performance difference between the Xantrex inverters and the SMA inverter is...
