Lousy service

I had a Sunsynk solar system installed in 2022 by a registered Sunsynk installer. All went well until about 3 weeks ago when some strange readings happened. There is a 10 year warrentee on the system. When enquiring from Sunsynk as to the solution I was told they did not supply the battery, the battery was sourced from Heroldts who were the importers. Heroldts informed us that we had to have the battery removed and brought in for repairs. No backup would be supp**** and the installer had to remove and transport it in for repairs. How long that will take is anyone's guess. On top of that I have to pay the installer for the job. Typical of the type of service customers receive from suppliers. Be aware of this type of shoddy service supp**** by these two companies.
