SPH 3000–6000TL BL-UP / SPH 4000–10000TL3 BH-UP hybrid (Error 2xx–6xx codes)
Growatt Error 507 error code
Output overload (displayed as 'Over Load'); the manual's first check is whether the load power is greater than the lithium battery's rated power.
Likely causes
- Total load above the battery's rated discharge power
- High inrush loads such as pumps, compressors or welders
- Too many appliances left on the backup circuit
- Battery discharge current limit set low in the BMS
Checks to run, in order
- 1Compare the measured load with the lithium battery's rated power
- 2Check the backup/EPS loads actually connected at the time of the fault
- 3Review the battery BMS discharge current limit
- 4Check whether the fault coincides with a motor or compressor starting
Fixes
- Reduce or stagger the load on the backup circuit
- Add battery capacity if the load is legitimate
- Restart the inverter after the load is reduced
When to escalate
If the load is within the battery and inverter ratings and Error 507 persists, ask Growatt support to review the inverter's power-limiting behaviour.
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 Growatt Error 507 mean?
Output overload (displayed as 'Over Load'); the manual's first check is whether the load power is greater than the lithium battery's rated power.
How do I fix Growatt Error 507?
Reduce or stagger the load on the backup circuit Add battery capacity if the load is legitimate Restart the inverter after the load is reduced
When should I escalate Growatt Error 507?
If the load is within the battery and inverter ratings and Error 507 persists, ask Growatt support to review the inverter's power-limiting behaviour.
Can I reset Growatt Error 507 myself?
Only after isolating the AC and DC sides and running the checks above. If Growatt Error 507 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Growatt Error 507?
Growatt Error 507 is documented for SPH 3000–6000TL BL-UP / SPH 4000–10000TL3 BH-UP hybrid (Error 2xx–6xx codes). Confirm the code on your own unit's display or manual before ordering parts.
More Growatt error codes
- Growatt 01Fan is locked (displayed as F01 on the SPF ES Lite).
- Growatt 02Internal component temperature is over 100 °C (F02 on the ES Lite).
- Growatt 03Battery is over-charged / battery voltage is too high (F03 on the ES Lite).
- Growatt 04Battery voltage low.
- Growatt 05Output is short-circuited (F05 on the ES Lite).
- Growatt 06Output voltage is too high. The manual groups 06/58 as 'output abnormal' — inverter voltage above 150 Vac or below 40 Vac.
