Solar Panel Monitor With Shunt

A solar monitoring system works through the solar system s inverter.

Solar panel monitor with shunt.

The example below shows a solar application but the same configuration can be used for any individual charge source or load that. Wired with 22 4 stranded alarm wire purchased at home depot for 30 cents per foot. My monitor choices were 100a and 500a and i could possibly draw up to 200a so the choice was obvious. Mounted flush adjacent to rv systems control panel.

The monitoring system works in a straightforward manner. In most cases companies sell their inverters with a patented built in monitoring software setup. Another reviewer mentioned using a dpdt swith to use one meter to monitor both charge and discharge. In the process of converting dc direct current from the panels to an ac.

On victron systems we recommend a lynx shunt on lithium systems using a color control monitor. Used 100 amp shunt. A 50a draw would be 5mv drop across the shunt which is a small loss and good tradeoff to provide the monitor capabilities. When energy conservation is critical a battery monitor is very helpful in educating you on the electrical consumption of your various devices as well as the charging potential of your solar array.

How do solar panel monitoring systems work. In order to monitor solar wind or hydro output a dedicated monitor needs to be installed with its shunt connected in the negative output line of the charge controller and upstream of the battery monitor shunt. Unit works as advertised and i am very pleased.
