SPH 3000–6000TL BL-UP / SPH 4000–10000TL3 BH-UP hybrid (Error 2xx–6xx codes)

Growatt Error 607 error code

EPS/backup output overload. The same event is shown as the 'Over Load' warning, and three overloads lock the off-grid function for one hour.

Likely causes

  • Connected backup load above the EPS output rating
  • Surge current from motors, pumps or compressors
  • Non-essential loads left on the backup board
  • Load connected during a grid outage that the inverter cannot carry

Checks to run, in order

  1. 1Add up the connected EPS load and compare with the EPS rating
  2. 2Check for high inrush appliances on the backup circuit
  3. 3Confirm only essential loads are on the EPS board
  4. 4Check whether the warning has tripped three times (off-grid locked for an hour)

Fixes

  • Move non-essential loads off the EPS output
  • Stagger motor starts or fit soft starters
  • Reduce the load and restart the inverter

When to escalate

If the connected load is within the EPS rating and Error 607 recurs, ask Growatt support to check the output power measurement.

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 607 mean?

EPS/backup output overload. The same event is shown as the 'Over Load' warning, and three overloads lock the off-grid function for one hour.

How do I fix Growatt Error 607?

Move non-essential loads off the EPS output Stagger motor starts or fit soft starters Reduce the load and restart the inverter

When should I escalate Growatt Error 607?

If the connected load is within the EPS rating and Error 607 recurs, ask Growatt support to check the output power measurement.

Can I reset Growatt Error 607 myself?

Only after isolating the AC and DC sides and running the checks above. If Growatt Error 607 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 607?

Growatt Error 607 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.
