January 28, 20233 yr Hi, my SunSynk is only charging my batteries at 140amps. I’ve set the charge on SunSynk to 185amp and I see the charge current limit on LiBMS screen displays 300amps. Am I missing a setting? System Sunsynk 8.8kw inverter 3 x 15kw DIY battery packs each with Seplos 200amp BMS 4.5kw Solar PV AC coupled Peter
January 28, 20233 yr You probably reached the requested voltage. Try discharging the batteries more, before charging.

They are down to 20% when charging starts and stop at 75%. I only have a charging window of 4hrs on my Octopus tariff so want to charge as much as possible in that window. It’s a constant amp through the charge. Edited January 28, 20233 yr by pedro54
February 5, 20233 yr Charging voltage might be too low ? What's your batteries config : 15S or 16S ? How much charging voltage & current have you setup on the BMS ?
