Solis alarm 1058: DSP firmware does not match the hardware
Solis alarm code 1058 usually means the inverter has detected a mismatch between DSP firmware and inverter hardware. DSP refers to the digital signal processor, which helps control inverter operation and power conversion.
Alarm code 1058 may appear as:
- DSP-SelfCheck
When this happens, the inverter may fail its selfcheck, stop producing power or prevent normal operation until the mismatch is resolved.
This type of issue may be linked to incorrect firmware, firmware update problems, model mismatch, internal software configuration or inverter control board behaviour.
Let e-Solar check your inverter firmware and model configuration
If Solis alarm 1058 appears, do not keep resetting the inverter without understanding why the fault is occurring.
Our Perth-based solar team can inspect the inverter, review the model details and help determine whether the issue is linked to firmware, hardware compatibility, software configuration or another inverter-related fault.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
- Your inverter model, if you know it
Do not attempt firmware changes or internal testing yourself. If the issue is persistent, a qualified technician may need to review inverter diagnostics, firmware version and hardware details before recommending repair, firmware support or replacement.
