The charge current may be too high for the kWh of the specific Pylon battery. I found an overshoot of voltage close to full-charge. The pylon opens up at this level and the resulting higher voltage on the output of the inverter triggers a fault. Lower current setting will limit the sudden rise close to full charge. I have a new (very new!) 3.5kWh pylon and at 30A and voltage setting of 53.5V on the inverter, it is fine as the current starts dropping before the voltage goes too high. It would be nice if the inverter could sense the faster rise in voltage close to the floating voltage level and cut back on current before the voltage goes too high, resulting in the Pylon disconnecting from the inverter, causing overvoltage. Today was my first experience with Axpert and Pylon, so I am still learning. Do your own test by starting with lower current and a voltage that is maybe at 53V max. This voltage may be too low over long term for protecting the battery, but still a good test for finding the problem. Regards. Smitty from Stellenbosch. No I am not a Robot, wishing I were.
