June 21, 20233 yr hie everyone please help me been having problems with averge lithium batteries connected to an Synapse 7.2kw inverter over discharging i have my dc cutoff set at 46vdc. i have 3 batteries wired in parallel.
June 21, 20233 yr Hi silvester begedu, welcome in the club. Nice rack for your packs! I put mine only face up on wooden blocks. I do not quite understand what you mean with "over discharge". The LEOCH BMS is set to low voltage cutout at 40.5V. I set my low cutout at the inverter to 42V. It has triggered few times during load shedding. At power return the inverters powered up automatically in line mode and recharged the batteries.

Welcome Silvester, are you not using communication between bms and inverter? Something else i want to mention connect your battery terminals staggered so you spread the load on the terminals as indicated in the Averge manual. See below:

Red to the top and Black to the bottom. The interconnecting cables look very thin though. But yes, I don't see communication cables either.

That way you spread the current on the terminals. Cables could be 16mm² or 25mm² difficult to see Edited June 21, 20233 yr by TaliaB
June 21, 20233 yr Okay, so connect cables to separate connectors on the middle battery. Not sure if that would make much difference, but it could be tried. The missing communication cables (green in your photo) could be tried too. The cables to the battery bank seems to be much thicker than the interconnection cables. That's something else which could be tried here: thicker interconnection cables.
June 26, 20233 yr Author Hello guys thank you for contributions will change the thin cables and put communication cable between the batteries as advised .One thing i need clarified does Synapse communicate with Averge batteries .
