The Aero-Sharp is a transformer-based inverter which was installed until 2011 and came in various sizes (1 kW, 1.5 kW, 2 kW and 3 kW). It was initially warranted for 5 years, but the latter models came with a 10-year warranty, shortly before the company went into liquidation.
If your solar inverter was installed by Solargain, you may be eligible for a replacement with an equivalent unit (such as a Macsol or SLK). Please note that the inverter is very heavy and cannot be moved by a single person, so you will need to book a maintenance service to have an install team visit your property and remove the unit for you. This will be charged to you, as the manufacturer does not cover call-out fees.
If your inverter is out of warranty or if it wasn't installed by Solargain, you will need to pay for a replacement unit. If you are exporting power back to the grid, we recommend you replace your Aero-Sharp with a Fronius Galvo, which has a similar system size, allowing you to continue benefiting from the feed-in tariff arrangement you have with your electricity retailer.
| Fault Code | Description | Remedy | |
| BIT Failure | Internal component has failed | The inverter needs to be replaced. | |
| Ground Fault | This could indicate an earth fault or, if permanent, the board may have fused. | We recommend you book a maintenance service to have a technician check for an earth leak. If none is detected, the inverter will need to be replaced. | |
| PV1 Over Volt | Internal component has failed | The inverter needs to be replaced. | |
| PV2 Over Volt | Internal component has failed | The inverter needs to be replaced. | |
| System Error | Internal component has failed | The inverter needs to be replaced. | |
| Grid Volt Error | An AC fuse may have blown or the AC board may be fused. | We recommend you book a maintenance service to have a technician check the AC fuse in the inverter and the AC board. The inverter may need replacing. | |
| PV Over power | Internal component has failed | The inverter needs to be replaced. | |
| Grid Freq Error | This fault may indicate an energy provider issue or the AC board may have fused. | If the fault is intermittent, this could be a legitimate power distributor issue. If it is permanent, the inverter will need replacing. | |
| TVS1 Failure | Internal component has failed | The inverter needs to be replaced. | |
| TVS2 Failure | Internal component has failed | The inverter needs to be replaced. | |
