Posted January 13, 20232 yr Hi All The 16kW SunSynk has dual battery input. Does anyone know if that will allow one to use 2 different battery types/brands? Example, using Hubble's on 1 input and BLS on the other.. Since there is only 1 can port, i guess battery voltages could be used... thoughts?

CAN is a parallel bus... so both battteries would pobably be able to talk on the CANbus... As for mixing, I don't think mixing LiIon and LiFePO4 is a good idea, but, I guess that's where the manual/spec sheet comes in, I always had the idea of 2 separate battery input on an inverter, one for LTO, high current but less sustained capacity and one for LiFePO4, lower current but but much higher sustained capacity. Bu even these have 2.3 or 2.4V nominal cell Voltage for LTO and 3.2V nominal cell Voltage for LiFePO4 and probably also very different charge/discharge Voltage curves... so mixing this, may be not so easy/ideal... ...also mixing 15S LiFePO4 and 16S LiFePO4 on the 2 inputs is possibly also not a great idea, but I guess see what the manual/spec sheet says Edited January 13, 20232 yr by Kalahari Meerkat ...also

Would have been an awesome feature to have .. ok, looking at that picture, this may simply be an easier way to connect some serious cables between the batteries and the inverter, I'd like to say, once the inverter is off, measure for continuity between the two positive and the two negative contacts, you may find they are interlinked and thus really only one battery connection and thus definitely no mixing of different cell numbers or chemistries...
