Aero-Sharp Inverter Faults

Submitted by Nedjma.Loucif on Tue, 18/04/2017 - 12:43

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.
