Anyone else running their garden office purely on solar through a UK winter?

Currently nursing my setup through another grey February — 200W of Renogy panels feeding a Victron SmartSolar MPPT into a pair of Fogstar Drift 100Ah lithium batteries. Some days I'm pulling in a heroic 8Wh before noon and calling it a win.

The office runs a monitor, laptop, a small fan heater on a timer, and LED lighting. Heater's the obvious villain — I've had to axe it most mornings and just wear an embarrassing number of jumpers instead.

Genuinely curious whether anyone's added panel wattage vs just accepted defeat and thrown a small grid feed-in as backup — at what point did you cave?

Hey @BayFrank, similar setup here but I swapped to a south-facing 30-degree tilt last autumn and it made a noticeable difference through the darker months — even on overcast days you're catching more of that low winter sun.

One thing worth checking is your Victron's absorption voltage settings for winter temps — lithium can behave a bit differently when the battery itself gets cold in an unheated space. The Fogstar Drift cells are decent but I've seen people run them slightly conservatively in sub-5°C conditions just to be safe.

What's your typical daily consumption looking like? I found ruthlessly auditing my loads (swapped to a 12V laptop charger, LED everything) made more difference than adding panels on marginal winter days.
