I purchased a FiveStar 48400 March 2024. I have back up inverter as the inverters seem to be better the weakest link in the chain.
On the evening of 16 November 2024 I heard crackling noises coming from the battery. After observing this for some time 30mins my inverter packed with a large grunt. I continued by connecting the battery to the backup inverter.
As soon as I switched the battery on I heard what sounded like a power surge through the inverter. I then switched off and disconnected the battery . I am now using my old lead acids and all works. Seems like my battery is poked.
Looking to have it tested .. any advice welcomed
