Hi I have a MultiPlus 12/3000/120-50 120V
I test the voltage out to the batteries I get 13.9 volts and 3.4 amps. Should the amps be more? Batteries also show 3.4 amps.
It sounds like the batteries are full, for any real help you need to provide more details, where you measured the voltage, Battery type, settings for the charger.
Hi … Thanks for the quick repose .
here is a history of what has been going on with my system, I will send you my settings shortly.
I finished the build and the system was working great except for a couple 120 outlets not working.
We took the van (2014 sprinter 170) on a 6k mile road trip to shake everything out and the van passed, system was charging using solar and the 12/12 alternator
and shore power .
-
second trip came along and started having charging issues.
-
checked the system and found the positive connection to the solar charger came loose and was arching due to bad ferals and vibration
-
I replaced the MPPT 100/50 solar charger with a new one added it to the system and still no charging.
-
Reset to system to the factory default and then reapplied suggested settings.
-
Rechecked the wiring and found some of my solar panel connections needed to be redone.
After all of that was complete and restarted the system is charging fine and this is the state I am in currently.
- But all of the 120 outlets the were working before my battles drained are no longer functioning.
This is what brings me to the AMP question , I checked the Voltage / Amperage output from the Multiplus to the battery bank…
I have a 4 battery bank using Simplfi PHI1.4 12 volt
Thanks….. settings on the way

As you have lithium batteries, if they are at 13.9V and only taking 4A then they are more than 99% full so they will not take much charge.
The other thing is to use a multimeter to check the Multiplus terminal voltage and the battery terminal voltage, these should be the same with only 4A, If they are different check all connections, fuses and breakers etc for voltage drop.
