Trimetric 2025 RV

This monitor requires either a 100 or 500 amp shunt. I cannot find any help on which one to choose. I am building a 560 watt solar system and have 2 pairs or Trojan T105's with 450 amp hours if that helps.

  • I too had a few questions when installing the 2025rv
    So picked up both the 100amp and the 500amp shunts
    Tried them both - depending on your system loads you might be forced to the 500amp shunt. The 100amp has a bit better resolution but not enough to stress over. I settled on the 500amp for the rigs 2025 installation and used the 100amp shunt on another install.
  • Hi,

    If you have not purchased yet, get the Victron monitor instead. It is cheaper and more fully featured than the Trimetric.
  • The 500A shunt has a 50mv drop white the 100A has a 100mv drop. Use the 500A shunt.

    Also depending upon what loads are on your battery you could exceed 100A.
  • It should have come with one
    http://www.bogartengineering.com has a list of dealers if all else fails
