Sunsynk Canbus compatible BMS
Good day all I had opened a new post but no response and then stumbled again on your post. Was wondering if you had managed to find the canbus link or protocols for the inverter as I have built same cell set up pls refer to below and the request im now getting from Daly themselves to supply the inverter protocols. Hopefully you have come right and could share or alternatively point me in right direction. I have been doing a lot of research and am very new and green to the whole concept so any help and assistance would be appreciated. Somewhere in these threads i saw "wanna be sparky" I think was the user name give advise on a 16s battery build to sunsynk inverter. I have two 48 v battery packs that are eve 3,2 v 105 a/h 16s however the supplier who i got cells from cannot give me the same composition cells which both top charge and balance to 3.42 v per cell when in parallel so the issue would be one set of cells having a top balance of 3,26 and the other 3.42 this when connected in parallel to inverter would mean having top and bottom balances vary and thus not have complete charge and discharge and full range of batteries ? correct me if im wrong? So I have two daly 150A 48V BMS and then 2 daly active balancers with BT that i was told by the supplier to get from electromann that can connect to their app and then hopefully manage each pack to their correct state of charges if i were to just use the the AGM charge V but this would mean mayby having to varied settings because of difference in packs or an i wrong? So upon further investigation and getting hold of Daly they suggest two parallel modules and two WNT boards and rs 485 or can communication parallel connector usb cable which they say will then allow proper balance of any two different voltage li-ion packs. But have asked that i give them the correct protocol fo the sunsynk 8 kw inverter so as to see if it can be interfaced. Any experience or advise on the above would really be appreciated as well as comm protocols if and where i can look for such? Rgds Newbie 1
