After close monitoring, the battery voltage was 54V and the inverter screen showed 67V.

I have a problem with my 11kW Ultra inverter I connected it to a lithium battery, and when it was fully charged, the battery voltage increased. At first, I thought the problem was with the battery. After a long struggle, I tried replacing the BMS board, but it didn't work. Yesterday, I tried replacing the battery with a different type, but the problem persisted. If I update the inverter, will that resolve the issue? Sorry for the long message.

I will go to the battery website and attach a photo of the cell voltage reading.

Someone told me that all batteries need their cell readings adjusted using BBMS Tools software.

All batteries are of the same age, but there is a difference in electrical voltage between all the cells inside the battery.

I have four lithium batteries connected in parallel, each with a capacity of 10 KW The problem is that when the SOS percentage for all four batteries is 100%, the voltage of the four batteries is not equal. Note that the BMS type is JBD

I have a problem with the axpert vm iii inverter. The lithium battery is not charged with more than 10 amps. U1: 60:13 U2: 25:16

I have a 4k VMlll inverter with a Felicity lithium battery connected to it. Sometimes, every day or two, an error 61 appears.

I did not make any update

Error 32 on the 3600W inverter screen

Thank you Mr. Coulomb

I have a problem with this device, it does not connect to the lithium battery. Can I update it to the following versions? U1: 71.97 U2: 2.70

Some users have 4.2 kW units. The unit type is winged. The following versions are available: U1: 68.06 U2: 28.01 What is the appropriate update for these devices?

I did all the protocol and cable requirements correctly and it still didn't work.

Battery type: Lithium Felicity

Can you help me update the device 3.5K VMIII U1 : 20.10 U2 : 2.68 The problem is not connecting to the lithium battery.

The damaged screen has version 60.02. The new screen has version 38.08. Can I upgrade from version 38.08 to version 62.03?

Thank you very much

Yes, that is what is meant.

I have a problem with my 11 kW inverter. The external screen malfunctioned, and I replaced it with another external screen. However, the screen software version was incompatible with the inverter software, as the old version was missing. U1 : 11.03 U2 : 62.02 Whereas in return, the software version of the screen that was replaced was released. U2 : 38.08

The problem is caused by incorrect charging behavior. U1 : 43.21 U3 : 02.08

I programmed the charge and float settings to 8.28. Of course, manual settings

Can you help me? I have a device that does not connect to a lithium battery.

I calibrated the cut-off voltage at 21 volts and the inverter has lead acid batteries connected but it cuts off at 24 volts.
