You can get estimate cost on the ags website. I imported a 3255 amplifier. Importand duties was around R500. Not a bargain for small item but ok for larger items. Price plus shipping still better than any local source
I have a 8kw sunsynk with two Revov 200ah batteries thats beren unning almost a year. It just works, no issues. We had a cable fault and was without power for 4 days. I was never off.
In the beginning I looked at the status several times a day but now I look at it probably every 3rd or 4th day...
