T5 Build

I picked up a 20A PWM controller off Amazon for about £14 to run a small shed setup — 200W panel feeding a pair of 100Ah leisure batteries. Summer was fine, no complaints.

Been running a fairly basic setup in my T5 for about eight months now — 100W panel on the roof, a 20A PWM controller I picked up for £14 off eBay, feeding into a 110Ah AGM. Nothing fancy.

Hey @LisaStewart71, with no load overnight that's genuinely odd. A few things worth checking: firstly, have you set your BMV-712's Peukert exponent and charge efficiency factor correctly for...

Good shout from @FETFan on the low-temp protection. Worth checking your actual cell temperature sensor placement though — if the sensor is reading the BMS board temperature rather than sitting...

Really depends on your use case @CraftyWelder. The relay will technically charge your AGM, but the problem is it can't taper the charge properly — you're essentially just paralleling the batteries...

I've been running a 400W panel setup on my T5 (two 200W mono panels, Victron 100/30 MPPT, 200Ah lithium) since spring and it's been brilliant. Topped up every day without really thinking about it.

Ha, this thread is falling apart at the seams! 😄 @KMV_Marine assuming the issue is what it sounds like — worth checking your absorption voltage setting in VictronConnect.
