Hi i have a Mecer Axpert originally installed 18 months ago together with 2.8kW of pv modules and 2x2.4kWh of pylontech batteries. It generally runs nicely but every few days it randomly trips with a 08 error, usually around 2 or 3am when the only load is the security lights and the fridge cycling on and off. I've had it replaced three times as my contractor thought it was a dodgy batch and has suggested changing it for an Axpert King. Does anyone know what could be causing the problem and will upgrading to the Axpert King fix it or is there an easier way. Thanks in advance for any help provided although please use non electrical engineering language as I'm a beginner at this.

Just spoken to my contractor who claims that I've never told him that it is an 08 error but this means that the inverter needs to be replaced and fortunately in my case it is still under warranty.

Hi All, I have had a 2.8kW PV system (8 x Canadian Solar 350W panels) installed on my home together with 2 x 2.kWh Pylontech Li-ion batteries and a raspberrypie linked to ICC software provides the load feedback. It is set to run in SBU mode, but trips almost every night around 3-5am when the only load is the fridge and a few fans and low wattage security lights. At this point the batteries are at 48.5-49V and 28-30% SOC. The error code shown is 08. Is it not possible for the inverter to switch to receive power from the grid? if so what settings do I need to adjust? Any ideas on how to resolve this would be most gratefully received.
