New-Build Energy Storage System with Solar, Lithium & Victron

Sue and her partner Mark are building a new house on a plot of land near the Dorset village of Beaminster in the UK. They want to be as eco-friendly and off-grid as much as possible and have a new Victron Energy Storage System (ESS) built. With solar on the roof and lithium batteries, they want ket house circuits to remain on even if the power grid goes off.
