Second update - so after mucking around with voltage drop calculators I realised the remaining 0.3v was probably coming from what I thought was a short run of 6mm (4.58mm2) cable out of the reg to the thicker leads that turned out to be nearly 2m. I did it so long ago I forgot where the cable...

Spot on Substrate - that's exactly why I didn't just crank the target volts up. However, an update on this one - the battery sense struggles with under bonnet temps and did not prove to be a reliable solution. So I have replaced the cable run with very thick battery cable - slightly thicker even...

100% understand that the reg should be close to the battery but this is on a 4wd with the battery under the bonnet and this is easier said than done. Under bonnet temps, water crossings etc all mean the reg really has to be inside the car. This introduces a minimum 3m cable run before you even...

Hi all, I recently switched from a 12v PWM (Curtech CT15A) controller to MPPT (Victron smartsolar 75/15) thinking it would be superior technology and slightly more efficient. However, my setup is such that there is about 6 or 7m of I think 6B&S cable between the reg and the battery (not ideal I...
