Shvncrvn Posted April 26, 2022 Posted April 26, 2022 Morning all, I have recently installed a SunSynk 5.5 inverter with a LiFePo 5Kwh /100ah Freedom Won battery. I would just want to ensure I have the right configuration for the unit. Currently everything is running nominal, the CT is connected the BMS is communicating etc. Would I still need to set settings manually for the battery if the BMS is communicating? I currently have the following settings: Gen signal ticked grid charged ticked grid signal ticked Battery float v: 55.2 Absorption v: 57.6 Equilization v: 57.6 90 days 0.0 hours https://ibb.co/VNwYP8W https://ibb.co/VpQwGJ3 https://ibb.co/s50FPGH https://ibb.co/BgpRrv1 https://ibb.co/dPr3Tsy https://ibb.co/CKrWrss Thanks a mil!

Shvncrvn Posted April 27, 2022 Author Posted April 27, 2022 Oh forgot to add; Charge amps: 40A Discharge amps: 120A Shutdown: 20% Low Batt: 35% Restart: 50% Quote
Shvncrvn Posted April 29, 2022 Author Posted April 29, 2022 I have changed my settings to 55.8v for float,equilisation and absorption with a max discharge of 100A and low batt to 30%. I am assuming this is what it should be from what I have read from other sources. Quote
mzezman Posted April 29, 2022 Posted April 29, 2022 For the Float, Eq and Absorption - what does the battery manual / sticker state? That should be your true north as the batteries all differ. You don't need Gen signal unless you have a generator connected to the inverter Your settings for shutdown, low batt and restart are ok - you can also change these to suit your usage, e.g. mine are 8, 10 and 12 respectively but i run my batteries down to 35% everyday. So if there is LS when we wake up i will still have between 35 and 8% usage Quote
Shvncrvn Posted April 29, 2022 Author Posted April 29, 2022 Thanks Mzezman, The sticker and manual talks about max settings. I found an interesting line in the manual stating 55.8v float and all other settings, so I set it as per the manual that i had to go find online (nothing in box). Wasn't too impressed with Freedom Won support either as I asked the support gentleman the same question on what the voltages should be and he referred me to whoever I bought the battery from. Surely giving that info isn't hard. Anyways - hoping I have it set up properly now. Quote
phidz Posted April 30, 2022 Posted April 30, 2022 You don't need to manually set the charge voltage settings if bms is communicating with inverter. Quote
