HESP three-phase hybrid (HESP H3/SH3 8-12 kW); code not listed in the single-phase HESP table
SRNE 36 error code
Balanced bridge arm overcurrent fault (Balance currentOC): the neutral/balance bridge arm exceeded its current limit.
Likely causes
- Unbalanced single-phase load on a three-phase output
- Large neutral current from nonlinear loads
- Output-stage hardware fault
- Load connected between phase and neutral beyond rating
Checks to run, in order
- 1Measure the current on each phase and the neutral
- 2Check how single-phase loads are distributed across phases
- 3Look for a large nonlinear load such as a welder or VFD
- 4Confirm the fault appears only with certain loads
Fixes
- Redistribute single-phase loads across the three phases
- Reduce the neutral current and restart
- If the fault appears with balanced load, refer the unit for output-stage repair
When to escalate
A balance-arm overcurrent with balanced loading indicates an output-stage fault and 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 36 mean?
Balanced bridge arm overcurrent fault (Balance currentOC): the neutral/balance bridge arm exceeded its current limit.
How do I fix SRNE 36?
Redistribute single-phase loads across the three phases Reduce the neutral current and restart If the fault appears with balanced load, refer the unit for output-stage repair
When should I escalate SRNE 36?
A balance-arm overcurrent with balanced loading indicates an output-stage fault and needs distributor service.
Can I reset SRNE 36 myself?
Only after isolating the AC and DC sides and running the checks above. If SRNE 36 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show SRNE 36?
SRNE 36 is documented for HESP three-phase hybrid (HESP H3/SH3 8-12 kW); code not listed in the single-phase HESP table. 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.
