Solarway will not honour warranty

just nowNEW-Edit Delete I purchased a property which has solar panels/inverter/batteries already installed. The system is 2 years old. The batteries have a 7 year warranty. One of the batteries is faulty and SOLARWAY SUPPIERS will not honour the warranty because the warranty is not registered under my name, but the previous owner. HOW RIDICULOUS!!! Am I first person to buy a house with a system installed ??? If I sell my 2 year old car, the warranty passes to the new owner!! WILL NEVER SUPPORT THIS **** COMPANY
