The LinkPro measures everything downstream of the shunt. If all the various batteries have their negative battery cables connected together either before the shunt or at the shut, then the LinkPro measures the amphour usage of all of them.
- - You really need to either learn how the system works or hire somebody who does. Obviously the original installer does not know how the LinkPro system works and did not install it correctly. If he knows he installed it correctly then the unit is defective and he should get you a replacement.
- - Besides the normal displays of amps and volts there is the display of amp-hours and a % display.
- - Inside the LinkPro you or the installer has to manually set the total amphour capacity of the batteries that the meter will be monitoring. If you have 800 amphours of batteries and the meter is set to 80 amphours it will show a rapidly decreasing % during discharge.
- - Also there is a manual setting for the algorithm that determines the % function. That can be manually reset or automatically reset by zero'ing the amphours reading when the batteries are fully charged. But the automatic function is not very good.
- - As stated by others, each wire to the LinkPro must be connected correctly according to the diagrams in the manual. Changing the wiring
willy-nilly can be a very expensive mistake. So either learn how to operate the LinkPro or get somebody who really has the knowledge to examine your system and can follow the instructions in the manual precisely.
