Powertech Power Meter 240V - For sizing off-grid systems, inveters etc

 

This is an essential tool for those trying to calculate power usage for off-grid systems. Many appliance will have a "power rating" written on them which is either wildely innacurate, or the peak power usage only. 
This intelligent power meter simply plugs into a normal power point (GPO) and turns it into a real-time power monitoring outlet. This meter will monitor the power usage of any appliance in real time, and will data log power usage over time (this is important for fridges, etc, that will only be on for a portion of the time) giving you accurate information.
You can enter the local price of your electricity and the meter will tell you exactly how much the appliance is costing to run. In addition, the power meter tracks the power used and can display the instantaneous voltage or current being drawn as well as the peak levels that have been drawn. The meter has backup batteries so it will not lose the stored data during a blackout or moving from point to point.
 
This meter will also montior POWER FACTOR. It is essential that you take into account power factor when sizing inveters and calculate energy usage. Power Factor is a measure of ineffeciancy in the device being measure, this increases the total power being drawn though the inverter and from the batteries.  The power factor will be given as a number between 1 and 100. This number is a percentage of ineffeciancy (phase distortion to be accurate) To apply this to the number of watts displayed, simpy divide by the percentage given. So if you appliace is coming up as drawing 800W, and the power factor is 86 the equation is 800 / 0.86 = 930W. So you need an inverter of more than 930W watts, etc. If you are having trouble with this you can simply call 1300 123 228 we will calcualte it for you.
