HESP series hybrid inverters (single-phase 4-12 kW and three-phase 8-12 kW)
SRNE 17 error code
Inverter short-circuit protection (InvShort): a short was detected on the AC output, so the output was switched off.
Likely causes
- Short circuit at the load output terminals
- Damaged cable or appliance
- Water in an outdoor socket or junction box
- Rodent damage to output wiring
Checks to run, in order
- 1Disconnect all loads and measure resistance/insulation across the output
- 2Inspect the output terminals and distribution board
- 3Check outdoor sockets and junction boxes for water
- 4Reconnect loads one at a time
Fixes
- Clear the short-circuit point, then re-power to resume output
- The inverter retries the output after about one minute and locks out after three attempts, so clear the fault before the third try
- Replace damaged cable or the faulty appliance
When to escalate
If the output is clear but the short-circuit protection trips immediately at start-up, the output stage needs distributor service.
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.
Questions installers ask
What does SRNE 17 mean?
Inverter short-circuit protection (InvShort): a short was detected on the AC output, so the output was switched off.
How do I fix SRNE 17?
Clear the short-circuit point, then re-power to resume output The inverter retries the output after about one minute and locks out after three attempts, so clear the fault before the third try Replace damaged cable or the faulty appliance
When should I escalate SRNE 17?
If the output is clear but the short-circuit protection trips immediately at start-up, the output stage needs distributor service.
Can I reset SRNE 17 myself?
Only after isolating the AC and DC sides and running the checks above. If SRNE 17 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show SRNE 17?
SRNE 17 is documented for HESP series hybrid inverters (single-phase 4-12 kW and three-phase 8-12 kW). Confirm the code on your own unit's display or manual before ordering parts.
More SRNE error codes
- SRNE 01Battery undervoltage alarm: the battery voltage has fallen below the [Batt. Under volt. alarm] value under Battery Setup, and the alarm does not by itself stop the output.
- SRNE 02Battery discharge average current overcurrent, detected by software (BatOverCurrSw); the inverter limits or stops discharge.
- SRNE 03Battery not connected (BatOpen): the inverter cannot see a battery on the DC side and stops the output.
- SRNE 04Battery undervoltage stop-discharge (BatLowEod): the battery has reached the low-voltage cut-off and the inverter has stopped discharging.
- SRNE 05Battery overcurrent detected by hardware protection (BatOverCurrHw); the inverter shuts the output down.
- SRNE 06Charging overvoltage protection (BatOverVolt): battery voltage rose above the over-voltage cut-off and charging was stopped.
