A121 training leveling up again. Showing methods to install batterys, EVs and consumer units outside. Without using Tin sheds, outdoor consumer units or basically replicate indoor installs outside. Just an approach we take as installers to build into our training simulations.

My sympathy to anyone in lofts this week. We have a rewire and solar project combined with solid floor (bungalow) the joy! Thankfully I have proposals and a trip out to meet a manufacturer of roof mounting kits that dont require screwing into rafters. My current reaction is a

Busy few weeks past and coming. Luckily a few new build roofs the next couple of weeks. Much easier than older plain tiles and slates lol. Checking installer dashboards and seeing MW of daily generation is sometimes the fruits of the labour we dont check up enough on! The

Dance Gala at the local cricket club this afternoon. Izzy and her friends were amazing. I dont know how they did it. Must have been a good 500 people watching. So brave and great to see so many families out supporting each other.
