XET MicroInverter XPX-A1000
The XET XPX-A1000 is a DC-to-AC inverter for solar panels. Every solar panel should have one, because it does something no other inverter does:
it provides any mix of active and reactive power.
That's important because most electronic equipment, all motors, all air-conditioning, nearly everything connected to the grid these days requires some mix. Sure, the utilities charge residential consumers only for their kilowatt-hour usage, because it used to be that their active power load strongly outweighed their reactive load. With all the new plasma and LCD TVs, all of the computer power supplies, and all of the electric cars expected to go onto the grid over the next few years, that percentage is growing.
And inverters that provide only active power are going to go the way of the dinosaur.
Currently the residential electric meter measures only the kilowatt-hours used. But that is likely going to change. The utilities have begun installing meters that measurereactive power use too. It won't be long before they are charging for it. Want to be ready for the day that happens? Then get an XPX-A1000.
Commercial and industry consumers have always been charged for their reactive use when the power factor drops below 90%. In fact, they aren't just charged, they are punished for letting it drop. The utilities assume that if the power factor drops below 90% even once, it happens a lot. A typical charge formula looks at the peak 15 minute meter usage, and multiplies that by the ratio of the target power factor (90%) to the actual power factor during that 15 minute period. So, even if the actual power factor is 90% during that period, the charge is based on the peak 15 minute demand. And the ratio increases if the power factor worsens.
That's not good. Want to save your electrical bill? Determine your reactive power draw, and set one of these XPX-A1000 devices to work providing your equipment with solar reactive instead of grid reactive power.
Interested in selling electricity to the utility? Soon the utilities will be buying reactive power, particularly when they need it to prevent brownouts and blackouts. But reactive power, locally produced, is always needed on the grid and both the US Department of Energy and regional utilities are discussing ways of buying it, rather than building new generation plants. So get with the flow, use XPX-A1000s and sell something, for once, to the utilities!
