| Code | What it means | What to do | Service | Manual |
|---|---|---|---|---|
| High Temperature Warning | The temperature of the HELIOS 3600 is too high. | Place the product in an open area for cooling. If you charge the unit immediately after it is fully discharged, this warning may appear. Wait 2-3 hours before charging. | owner | p. 9 |
| Low Temperature Warning | The current battery temperature is low, which reduces charging efficiency. | Keep using the product. Charging efficiency returns to normal as the temperature rises. | owner | p. 9 |
| Overload Warning | The HELIOS 3600 is overloaded. Output ports are drawing more power than the rated limit for that port or the total output. | Unplug the AC load(s) that caused the overload. Unplugging the load clears the alarm and restores normal output. For 120V AC, total output across all ports is up to 3600W. For 240V AC, it is up to 2200W. For DC and USB, each single port has its own rated limit. | owner | p. 9 |
| A01 Fan Blockage | The cooling fan is blocked. | Check whether the fan is blocked. If so, turn off the machine, remove the blockage, then restart the product. If the problem persists, contact Growatt Customer Service. | dealer | p. 23 |
| A02 Inverter Over Temperature | The inverter has overheated. | Turn off the product and place it in an open area for 2-3 hours. After cooling, the product will continue to work normally. | owner | p. 23 |
| A03 AC Overload | The AC output load exceeds the allowed limit. | Unplug part or all of the loads and keep the total output within 3600W to resume normal operation. Long-term overload may cause product damage. | owner | p. 23 |
| A06 USB-A Output Overload | The USB-A output exceeds the maximum output of the USB port. | Check the output of your USB devices. Remove the USB device(s) if the output exceeds the maximum output of the USB port(s). | owner | p. 23 |
| A08 PV Over Temperature | The solar (PV) charging circuit has overheated. | Turn off the product and place it in an open area for 2-3 hours. After cooling, the product will continue to work normally. | owner | p. 23 |
| A09 Discharge Over Temperature | The battery has overheated while discharging. | Turn off the product and place it in an open area for 2-3 hours. After cooling, the product will continue to work normally. | owner | p. 23 |
| A10 Charge Over Temperature | The battery has overheated while charging. | Turn off the product and place it in an open area for 2-3 hours. After cooling, the product will continue to work normally. | owner | p. 23 |
| A12 Car Cigarette Lighter Output Port Overload | The car cigarette lighter output exceeds the port's maximum output. | Check the output of your devices. Remove your device if the output exceeds the maximum output of the Car Cigarette Lighter Output Port. | owner | p. 23 |
| A24 USB-C Output Overload | The USB-C output exceeds the maximum output of the USB port. | Check the output of your USB devices. Remove the USB device(s) if the output exceeds the maximum output of the USB port(s). | owner | p. 23 |
| A25 Charge Low Temperature | The battery is too cold to charge. | Move the product to a warmer spot or connect it to AC/PV power before use. | owner | p. 23 |
| A26 Discharge Low Temperature | The battery is too cold to discharge. | Move the product to a warmer spot or connect it to AC/PV power before use. | owner | p. 23 |
| A27 Inverter Low Temperature | The inverter is too cold to operate. | Move the product to a warmer spot or connect it to AC/PV power before use. | owner | p. 23 |
| A28 Anderson Over Temperature | The Anderson port has overheated. | Turn off the product and place it in an open area for 2-3 hours. After cooling, the product will continue to work normally. | owner | p. 23 |
| A29 Anderson Overload | The Anderson output exceeds the maximum output of the Anderson port. | Check the output of your Anderson devices. Remove your Anderson device if the output exceeds the maximum output of the Anderson port. | owner | p. 23 |
| A30 PV Over Current | The solar input current is outside the specifications for solar charging. | Check whether the input meets the specifications of solar charging. Remove the solar input to resume normal operation. | owner | p. 23 |
| F01 Output Short Circuit | The output has a short circuit, most likely caused by a problem with the connected loads. | Check the output loads for a problem and remove them to resume normal operation. If the problem persists, contact Growatt Customer Service. | dealer | p. 23 |
| F02 Product Over Temperature | The product has overheated. | Turn off the product and place it in an open area for 2-3 hours. After cooling, the product will continue to work normally. | owner | p. 23 |
| F03 Product Overload | The total output load on the product exceeds its rated capacity. | Unplug part or all of the loads and keep the total output within 3600W to resume normal operation. | owner | p. 23 |
| F13 Inverter Low Temperature | The inverter is too cold to operate. | Move the product to a warmer spot or connect it to AC/PV power before use. | owner | p. 23 |
| F14 System Failure | An internal system fault has occurred. | Restart the portable power station. If the problem persists after several attempts, contact Growatt Customer Service. | dealer | p. 23 |
| A31 240V Outlet Overload | The 240V AC outlet output exceeds its maximum output. | Check the output of your 240Vac devices. Remove your 240Vac device if the output exceeds the maximum output of the 240V AC Outlet port. | owner | p. 24 |
| A32 Split-phase Output Overload | The split-phase output exceeds the maximum output of the split-phase outlet port. | Check the output of your 240Vac split-phase devices. Remove your 240Vac split-phase device if the output exceeds the maximum output of the split-phase Outlet port. | owner | p. 24 |
