A friend of mine starting out in his solar journey has been quoted on a 5.12kWh Volta Stage 1 Battery.
Does anyone have experience or knowledge of this battery? He was told it comes with a 10 year warranty.
Also, the quote paired it with a Sun Synk 5kw inverter. Are these two a good combination? Does the Sun Synk now have a 10 year warranty as well? My understanding is the 10 year warranty was only applicable if paired with the Sun Synk inverter?
Any advice is appreciated
