What it means
The manual says: Over Load in EPS Mode - turn off high power device, press ESC to restart.
Part involved: Backup/EPS output overload.
Likely causes:
- As described in manual.
Is it safe?
| Does the inverter stop? | Partly |
|---|---|
| Severity | Fault — needs a manual reset once the cause is fixed |
The inverter keeps running with some functions stopped.
Resetting itself: brand-dependent.
Manual reset: reduce load then restart.
What you can check
- Read and note the exact code and time from the inverter display or app (screenshot).
- During a power cut, switch off large loads (kettle, oven, heaters) on backup circuits.
- Where the SolaX manual says 'press the ESC key to restart the inverter', a homeowner can do that on the display. Steps that say 'disconnect PV+/PV-/battery' are for the installer only.
What the engineer will check
- Check backup circuit design vs inverter EPS rating.
- Check for inrush/non-linear loads.
Who to ask for: Battery installer.
Certification: Electrician competent in electrical energy storage (BS 7671 Chapter 57; IET Code of Practice for Electrical Energy Storage Systems), ideally the MCS battery installer (MIS 3012); brand-approved installer to keep warranty.
