Can the solar container system be placed indoors

Solar panels are made for outdoor use, but they can work if set up near a window. A solar container is essentially a portable, self-contained unit equipped with solar panels that harness sunlight to generate electricity. They work in conjunction with a solar PV system to capture surplus energy produced during sunny days when the sun's. Anyone have any experience with systems installed inside main living area - particularly concerning code & permitting? We're doing an off-grid new build and I want to put the batteries and inverter/charger inside the house in a utility room.
