Hello everyone, I have a Tescom VM 5K 450VDC solar MPPT inverter which for no reason started showing error 32 and became unusable. I know that this is a lack of communication between the inverter and the display, and to fix it, the firmware of the inverter must be updated. The display is solid with software U2: 0261 and works (I tried it on another inverter). Please help me from where to download software for my inverter.
