@Squib82 and @DaiHendrei nailed it. Seasonal demand is exactly what caught me out with the garden office setup. Thought I'd cracked it in summer with 4kW solar — felt bulletproof.

Measurement's crucial mate. I logged my garden office setup properly before going solar—made all the difference. Cheap clamp meter from Screwfix sorted it.

VSR's definitely the answer here. I've got a Victron Cyrix-li on my garden office setup—works a treat. Just wire it between your batteries and let it handle the switching automatically.

Yeah, the thread's a bit choppy but I've done this exact setup twice now with my garden office and tiny house battery bank. Key thing nobody mentions: your MPPT output voltage needs to sit...
