Keep you bms over voltage protection at 3.65 and set your charge controller at 56v which is 3.5 per cell..
Sorry but i consider this wrong way of thinking, why? at 3.65 cell is at MAX V so going...
what do you say, settings are ok in MPPT?
problem is this, one cell will always charge faster -> will reach the OVP, when this is the case BMS must turn charge OFF if cannot keep cell voltage under the set OVP with balance current.
not ON one sec and OFF next second and so one, my opinion...
Tis 8s bms is working has expected when one cell is over the set OVP charge is off
the 24S black BMS worked the same way when it was on the UPS in 8S config with DC-DC converter to get the min V of the BMS to turn ON
in attachment is the 8s BMS and charge is off when cell OVP is reached,
yes...
Hello
i have some problems my setup
Victron MULTIPLUS-II 48/5000/70-50 GX -> grid is connected no feed in is set and ext. current sensor connected
Victron Energy SmartSolar MPPT 250/100 VE.Can, connected to inverter by ve.direct
Victron Energy Lynx Power In as a buss bar
Victron Smartshunt...
well i read user manual so many times that i can reproduce it for an exam
i have a felling that BMS cannot switch off charging wen charging current is over a certain value of amps 10 -> 15 -> 20 A, i do not know
i will test this hope in the near future
reason i say this is because this BMS...
what app you are using with this bms
i use ENJpower because first time i scan the QR code from bms page would not load so i search JK BMS and i find this
https://www.jkbms.com/support/ and if you click on google play or Apple Store app will download
after install app connection to BMS was...
well beside that charge is switched ON/OFF almost each second and if you "watch" the clip this is done with charge function set to OFF then i hope you see the problem
and charging with 10->15 A one sec and discharging with same amp next sec and outside is full sunshine is not the right...
and do not care abut the charge on/off switch state, charge switch is set to of and still repeatedly switch charge on off and on
my first BMS is this JK and all 16 cells are new
and i have 2nd jk an 8s now for the UPS
Worked fine for 6 months on a 8s LiFePO4 with a DC-DC Converter, battery connected to and UPS
Charging with max 5A and discharging with no more then 25
Now i managed to install and connect all my Victron solar gears
