I had a system which worked 2 110 ah AGM batteries with a Sterling 30 ah charger, everyone was saying go lithium for more power so I bought 2 100ah lithium batteries but my Sterling charger was confusing to set up with rows of leds and push buttons.
Again people were saying by Victron dc to dc as better product, I thought it would be like my Victron hook up charger and solar charger both dead easy with the Victron app, but know it’s a bloody nightmare, 12 volt planet who I bought the 50 ah Orion off can’t understand why it’s not working properly. Now they have got in touch with their supplier who wants to know size of cable, make of lithium batteries, output of alternator and the serial number of the Victron.
I wish I had not gone lithium and had this nightmare that I’m having.
