For a new house I have proposals of roughly same amount for: 12kVA Dye plus two Dyness 16 (so 12+32) and 6.9kW JA Solar 10kVA Fox plus two Fox EP12 (so 10 +24) and 6.9kW JA Solar I do realize that both systems have a LOT of storage but imho storage is now dirt cheap and I would rather have more than house energy balance needs so that I can tap-dance Eskom powerflex Time of Use tariff easier. I’m resigned to having to register. This way I have one install and won’t ever need to upgrade storage quantity. The garage is awkward so I will probably need to wall mount the batteries above hip height, making those Dyness PowerBrick systems a challenge. A third option for about same price is Sigen 10 + Sigen 10+6 (so 10+16) and 6.4kW Aiko solar Beyond installation, which is the more reliable product with better after-sales support and system / apps?
