STANDARD OR NET METERING

Description

NET metering applies to electrical systems which incorporate a power generating source such as solar or

wind and sells energy to the power company when the power generated exceeds the power consumed.

Monitoring such systems requires that the power meter has the ability to determine the direction of

power flow. The GEM therefore provides a polarity to identify the direction of flow.

By default, all measured energy consumed is specified as a positive value. Any of the 32 channels may

be enabled to indicate the polarity of the measured power.

Setting

The metering option should be set to “standard” for all channels unless:

 The system has an inverter and a solar, wind or other generating system sending energy to the

electrical grid.

 The system is 3-phase.

If NET metering is not required, all channels should be set to “Standard”. Do this using the following

procedure:

1. Check “Set All Channels”

2. Click the “Standard” radio button

3. Click “Save”

If NET metering is required (generating power), all channels should be set to “Standard” as described

above, then NET metering should be selected one at a time by selecting the channel number, NET radio

button then clicking “Save”. Typically the channels set to net would be the “inverter” (solar or wind) and

main panel channels.

CHANNEL POLARITY

This option is used to toggle the polarity of a single energy channel. This function is active only if the

selected channel is enabled for NET metering otherwise the polarity has no effect.

Description

It is standard to display consumed energy as a positive value when energy monitoring. If a renewable

system is generating more energy than is being consumed, the resulting energy is represented as a

negative value. It is quite possible that the polarity is opposite of what it should be. This depends on
