Trimetric 2030 battery monitor

After hooking the charger up properly, everything seems to be working properly except state of charge. I'm at 12.5 volts and still showing 96%.

To see what your panels are putting out get to "SOL" mode on your trimetric. Then turn on enough loads on your batteries so the battery voltage gets below 13 volts. Then your panels will be pumping max amps which you can observe on the SOL display.

Charger and solar off, turn a light etc. on/off and note it's draw. Handy to have a table of battery loads.

The monitor reflects the battery amps only and not charger/solar amps. For example with the charger off assume solar shows 20A and with 5A house loads the 2030 will show 15A to a discharged battery.

I had to tweek the settings a little for it to register 100% SOC with a fully charged battery. I have the 2025 RV model but essentially the same monitor.

Sounds like the charger is connected to the battery post rather than the frame side of the shunt.

It was indeed connected to the battery posts. I wasn't aware that was an issue. I'm learning as I go. That solved the amps in problem. I'll charge it and discharge it some and see how the SoC works.

Thanks.

As stated all items should have their negatives (including the solar controller) on the outer end of the Trimetric shunt with only one (fat) wire between the inner end of the shunt and the neg battery (bank) post.

Another thing is with more than one charger, the batteries will only accept charge from the highest voltage charger if the voltages are too far apart. The lower voltage charger will supply no amps. If the chargers are near the same voltage they will add their amps and that will show on the Trimetic.

Hard to tell from the OP, but perhaps you have either not connected all 12v items to the outer end of the shunt, and/or you have one charger at a lower voltage than the other.

The monitor should show the amps in or out (negative) of the battery regardless of any charging or any loads or any combination of the two. Doesn't sound like yours is working correctly.

Sounds like the charger is connected to the battery post rather than the frame side of the shunt. Remove pedestal power and turn on some lights. Does the 2030 show the negative amps? Leave the lights on for awhile, turn the charger on and you should see positive amps going into the battery.

Make sure there are no parallel paths from the negative battery post(s) to the frame ground. All battery amps must go through the single shunt path. Check all of the small control wires from the shunt and positive battery posts and make sure they are wired correctly.

Until the amps and voltage display correctly I wouldn't be concerned about the SOC display. And make sure all of the battery parameters are set correctly for the SOC.
