      Replacement Inverter 

A customer could not track down the installer who fitted her solar system over 10 years ago so we popped out and took a look at her failed system. We carried out a full test, inspect and health check and unfortunately it resulted in us having to replace the aged failed Schucco inverter with this nice new 6th generation Solis Inverter. Her system is now back up running and generating as it should do and earning her money again via her  feed in tariff agreement.
