Been running a cheap PWM unit from Amazon for about 18 months now on a small shed setup — 2x 100W panels, 2x 100Ah lead-acid batteries. Paid about £18 for it.

Been keeping an eye on the Sungold split-phase units for a while now — the 10kW 48V variant is interesting on paper, particularly for anyone running a North American-style 120/240V split-phase...

@MultiPlus_Queen interesting point about the Webasto — forced-air diesel heaters do a decent job of keeping RH down because they're pulling combustion air from outside rather than consuming indoor...

Yeah, it's not just you. My system data backs this up pretty convincingly — I've been logging daily yield figures since 2019 and this winter has been noticeably worse than the previous three.

Mate, 10kWh is actually decent for a static setup—problem is most people underestimate winter losses.

The real issue is storage versus generation. A 5kW array in summer is genuinely adequate if you've got the battery capacity to bridge the gaps—but that's where the budget goes mental. I'm running...
