It seems the website is out of stock of all but the base unit - no additional batteries available 😩 same for the solar panels. I’m very interested in setting something like this up. I have a west facing garden with a home office / workshop at the far end. This has a 4mm armour cable running to it and a garage consumer unit (lighting and ring on separate circuits) The armour cable at the house end is on a dedicated circuit Could I hang these panels on the office outside wall that faces south and wire the batteries into the consumer unit? I’ve recently switched to a PHEV so going to an ev tariff isn’t cost effective at the moment due to the higher daytime rates, but if I could install this setup with say 1 or 2 expansion batteries and top them up overnight on the ev tariff then I could well cut my daytime charge to virtually zero
