Electrical Energy Power Voltage & Wattage Loads

Whether grid tied or off grid electrical alternative energy power AC voltage both take wattage to operate AC electrical devices like lights, outlet loads, pumps and everything inbetween!

Grid tied relies on the Main Breaker or Fuse, load side meter design amperage rating. 

Off grid relies on system design to match onsite electrical energy daily wattage usage.

AC electrical energy power voltage has many theories from the very start of its invention.

An example of this is that by raising voltage lowers amperage for the very same wattage being operated, the formula is wattage/voltage=amperage & voltage X amperage=wattage.  A standard grid tied secondary that is 200 amp 120 240 voltage single phase residential line drop is 48,000 watts controlled by Main Breaker and billed by utility meter.  This same grid tied 48,000 wattage load is only 6.67 amps on primary Line Side 7200 volts and then transformed down to secondary.

Off grid alternative electrical energy power voltage can greatly benefit from the history of  AC electrical power by mixing and matching the numbers. The same off the shelf grid quality utility transformers are available for wind and solar switching PLC SCADA for grid tied or remote onsite system designs. Needless to say this has angered some utilities and they do not allow Primary or Secondary Net Metering into their utility grids. The next step than is NET ZERO it is very easy to legally stop a grid tied utility meter from spinning for days or weeks at a time before any battery bank or banking charging maybe required.

Today's grid quality off the shelf  DC to AC inverters are so fast on switching from one voltage source to another voltage source that clock or computer resets are not necessary.

The same principles apply to AC transformers whether grid tied or off grid alternative electrical energy as long as the quality of the voltage is designed to be matched.

An example if a grid tied service drop was back feeded by an onsite 120 240 volt generator  it would charge the transformer to 7200 volts if there was no grid tied voltage present. If the secondary line was energised by utility voltage it would blow the generator up and possibly cause a fire. Not good ideas as it could also kill a linesman or oneself if improperly designed and operated. This is why ATS (automatic transfer switch) protects and switches various voltages from one another.  ATS is no more than a contactor based system that can be either normally open or normally closed once again it is in system design.

By taking grid quality off the shelf vendor products from various vendors worldwide makes it possible to have grid quality electrical energy even out in the middle of nowhere and the options are endless for wattage and voltage requirements in single or three phase options. 

By mixing solar and wind and any alternative energy a microgrid is formed and the options are endless as everyone's needs differ from their onsite wattage load requirements. D B Electric solution is to custom tailored each individual onsite usage demands and built in stages as funding permits. Bottom line alternative electrical energy is an investment that pays for itself and system design makes it safe, reliable and efficient.
