April 20, 20242 yr Hi everyone, I was hoping someone could give me some advice. I have a RCT-AXVM2 12v system and it just started giving me problems. For some reason it is reading the battery voltage incorrectly. My battery via Bluetooth and using the multimeter is reading say 13.2v but my inverter is sensing 14.4v so only gives a trickle charge not enough to charge the battery. Interestingly enough I cannot even charger it from utility as well. It all started a few weeks ago when the inverter started clicking all the time. Looking at the display it is almost as if it is see between charging the battery and using the battery. I think this is because it constantly reads the voltage incorrectly. Any ideas or suggested fixes it would be really appreciated.

Because it reads higher alsk adjust your settings for going to battery and cut out higher to compensate. In which area of the country are you?
April 28, 20242 yr Author Just some feedback ppl, in case anyone else has this issue. I found that the positive terminal in the inverter was partially melted, and was not making a good connection, or at least a partial connection to the battery. This seems to have been contributed to the issue. I have seated everything correctly, and everything seems to be working again.

In 12v and 24v systems you run relatively high currents so it is of utmost importance to ensure no loose connections on battery connections. Hence the reason why manufacturer torque settings is so important.
