Do I Need To De-rate an AVR When Installed At High Altitudes?

Yes. A fan cooled Automatic Voltage Regulator (AVR) must be de-rated at altitudes above 2000 meters. At 2000 meters, de-rate by 18%. and then by 9% for every 1000 meters. So At 3000 meters, de-rate by 27% and so on

If an iVolt or AVR is exposed to a reverse voltage can this damage it or does it protect itself?

Introduction When considering methods to save energy consumption in a building there are a range of possible technologies you may be considering. Along with an iVolt to reduce the electricity consumption, you may also be think looking at using solar PV, or may already have it installed. The question is, “Will the iVolt and grid connected solar PV work well together?” The answer is “Yes”, provided the system is connected in the correct way. Connection of an iVolt An iVolt reduces and regulates the voltage of the power supplied to a building. It is connected between the incoming supply and the AC distribution panel. This way all loads in the building will benefit from the regulated voltage and reduction in power. Figure 1 shows this configuration. Connection of Grid PV systems A PV system is usually connected as shown in Figure 2 (excluding the iVolt installation, highlighted in red). The solar modules feed power to a PV inverter, which changes the DC power to AC power and feeds it into the AC power system. Power from the solar inverter can be flow in either direction; a) into the house to reduce the electricity imported from the grid, or b) exported out to the grid, when there is more power from the solar than is required by the house. A dual electricity meter is required so that it will record both the normal import consumption from the grid as well as credits when exporting power to the grid. These are charged at different tariffs. Correct Connection of an iVolt and Grid Connected PV In the case where an iVolt is used along with a solar PV system, it is important to connect the solar PV inverter at the point between the meter and the iVolt input – this is shown in Figure 2.

Is the AVR set to 220 or 230 or 240V nominal?

The Automatic Voltage Regulators (AVRs) are normally set to 220V. It can operate normally and safely with 230V or 240V. In fact, the output will be reduced to 220V +/-4% which will be a better operating voltage for most electrical/electronic equipment and can additional save energy with certain type of equipment.

Voltage regulators stabilise the voltage when it fluctuates, up or down. They are essential whenever reliable power is needed or when normal operation of electrical or electronic equipment is disrupted by the variations.
