Bi directional meters have three display screens.
Good voltage meter for solar panel.
Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
For example if your panel has approval for 30 volts set the multimeter to have a higher reading.
One is a test screen where all lights are on.
The second shows power coming in from the grid and the third shows power going out from your solar into the grid.
Make sure that you are measuring at the suitable voltage level for a solar panel.
Some exceptions may apply based on panel type.
Bi directional electricity meters are capable of measuring electricity that flows to and from the grid.
Doing this will give you the confidence and assurance that your readings will be accurate.
Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v.
In order to participate in net metering you will only need to add one additional piece of equipment to a standard grid tied solar panel system a bi directional meter.
Consult your solar panel s documentation for information or contact our technical support desk.
