This is a question for GE staff. But can anyone install a second battery or does it need a qualified electrician to do it? I ask as I can get another 8.2kw battery for £2565 but to get one installed by a local dealer is £3300 or EON £3480. £700+ is a tad hard to swallow. The install guide suggests just 3 wires are needed and I have a mate who's a sparky who would assist me.
