How to Solve Error 32 with Hybrid and Off-Grid Inverters Voltronic/Voltacon/Axpert / Infinisolar

This error is related to a software fault or potential hardware issue on the digital signal processor board. If you see this error on the screen of a hybrid or off grid inverter, it is advisable to repalce the DSP board first. You also have to inspect the firmware version of the new card to match the model of your inverter.

If the DSP appears to be healthy, then the second (and final part) card that needs inspection is the communication board. This board establishes the data transfer between the screen and the DSP board. It also bring together the communication from other external sources like BMS card, modbus card and LCD screen.
