How To Connect Amp Meter To Solar Panel

As you can see in the solar meter base the wiring actually looks backwards.

How to connect amp meter to solar panel.

Wiring diagram of a typical residential solar metering installation. So you can buy a panel ammeter with a built in shunt or use a separate shunt wired in at the battery s. In this video i show how to wire up a solar panel power meter in my vw t4 campervan conversion with links at the end for the items. I am running one 20watt solar panel loading.

The wires in the top terminal go out to the solar panels and the wires on the bottom terminals go back and tie in to the utility. To test a 18v solar panel voltage output directly put your solar panel in direct sunlight set your multi meter to the dc volts setting. But meter and shunt must be matched. The power meter is a chea.

You want to choose a voltage range capable of displaying the maximum possible voltage of the panel in open circuit this means that if you have a panel rated for 20 volts you should set the multi meter. A fused disconnect is always used and goes out to the solar panels. To measure the power going into your battery from your solar panel s put the battery on the load side and the solar controller on the source. The meter displays the small voltage as amps.

The meter side is not measuring current directly but the very low voltage drop across the shunt so the meter and the shunt have to be matched. In this video i show how to properly wire an ammeter amp gau. I ll show you how.
