SMS Sunmate Solar 05 error code
Output short circuit: a short is detected on the AC output.
Likely causes
- Short circuit in the AC output wiring
- Faulty appliance plugged into the output
- Water ingress in a socket or junction box
- Damaged output cable insulation
Checks to run, in order
- 1Switch the inverter off and isolate every load
- 2Insulation-resistance test the output wiring
- 3Inspect sockets and junction boxes for water damage or burning
- 4Restart with no load connected and add loads one at a time
Fixes
- Repair or replace the shorted output wiring
- Remove the faulty appliance from the output
- Dry and repair water-damaged accessories, then retest
When to escalate
If code 05 appears with nothing connected to the output, the inverter output stage is faulty — return it to the distributor's service centre.
Fix it with the right tools
Check the system around the fault before replacing parts: load, battery bank, PV string and commissioning settings. If you need a second opinion, send the code and your inverter model to our team.
Before you open the inverter
- Isolate both the AC and DC sides, then confirm the display is dead before touching terminals.
- Use insulated tools and one hand where possible. DC arcs do not self-extinguish like AC.
- If you see burnt terminals, swollen cells, leaking electrolyte or a burning smell, stop and escalate instead of resetting the fault.

More SMS Sunmate Solar error codes
- SMS Sunmate Solar 01Fan failure: the cooling fan is blocked or not turning. The same code appears as a warning when the fan is blocked while the inverter is running.
- SMS Sunmate Solar 02Over-temperature: internal component temperature above 100 °C, or converter temperature above 120 °C.
- SMS Sunmate Solar 03Battery over-voltage: the battery bank is charged above the inverter's high-voltage limit. The same number is also used as a warning (beep once per second) when the battery is overcharged.
- SMS Sunmate Solar 04Battery under-voltage: the bank has discharged below the inverter's low-voltage cutoff. The same number is also used as a low-battery warning (beep once per second).
- SMS Sunmate Solar 06Abnormal output voltage: the inverter output is above 260 V AC (the manual groups 06 and 58 as output voltage outside the 190–260 V AC band).
- SMS Sunmate Solar 07Overload timeout: the inverter has been loaded above 110% of its rating and the overload timer has expired, so the output is switched off.
