I know what you are thinking here,"can't be the battery it's only two years old" :)
Wrong!, the location of the panel and the environment temperature plays a key factor in battery life.
We have several systems that need the battery changing annually,not only because of it's location but as a precautionary measure.
Listen to the lads they know what they are talking about.
Clueless.. why mention the mains frequency? And why would an old veritas that's been in situ for donkeys years suddenly change from 50 to 60 htz?.
Makes no sense ????????.
Are you one of them techy guys in an office who folk speak to when there's a fault/issue cos I dont think you are engineer?
