Thansk , they have quite a range too .

I find it bizzaire that is required , you can get decent clamp DC mutimeters for under R1000 which measure 600A with good precision. The sensor itself cannot be more than R150 itself .

I looking for a 100 A DC current sensor - so I can monitor the current balnce between two battery banks on a common busbar. It must not break into existing wiring - so a Hall effect clamp than can be permanently fitted . Cannot find anything?

Lithium cell lieftime is a very complex issue - in general high voltage reduces life expectancy - so if you only using 30% of your battery its better to operate 50 - 20 % SOC as opposed to 100 - 70% SOC . This can be a challendge to get your charge to charge up to a SOC level as opposed to a voltage level . You can do this with a multiplus and a venus using a 2 wire BMS assitant .

Good to know. Is it really quite that it wont upset the neighbours I wonder

Thanks , its a 5000VA 48V 100A/70 Multi. Doing my due diligence before going offgrid one day

HAve been sold thanks

Anyone had experience with actually getting a generator to sync with Victron Multiplus / Quattro - which ones do and which don't?

keen to find out how well the REC - BMS works with the Victron Venus system. Is anyone using it on this forum ? http://www.rec-bms.com/datasheet/UserManual_REC_Victron_BMS.pdf

Yes still available

You can parallel the 2 phases ( load side ) in your DB board effectively ignoring one incoming phase. Cannot do so on the supply side that will result in a big bang. HAve one phase as maintained supply ( plugs lights ) and the other direct Eskom supply - Geysers, oven etc

Meteoblue predict solar radiation in their 2 day weather forecast - not too bad . https://www.meteoblue.com/en/weather/aviation/air/-34.108N18.374E7_Africa%2FJohannesburg . SMA also do if you have a SMA inverter .

Big problem is that Pylontech are 15 cell LiFePo4 batteries , almost everyone else is 16 cell - so if your 100Ah x 2 bank is made up of 15 cells then it should be Ok if not using CANBUS control - else I doubt it could work reliably

I'm look for someone with the necessary equipment to calibrate a Fluke 87 in CapeTown ( at a reasonable price ) - anyone?

I guess its just the top cell that gets burnt off . I have seen a video where the cell 8 can external drive a lamp load , not sure if they were discharging or balancing

Thanks for the info - do you need external balance loads to implement the balancing or is it an active balancer? 400ma x3.2V x 8 cells = 10 watts which will generate quite a lot of heat? Do the displays stayon all the time or do they "timeout " after a while

Has anyone used one of these multichannel battery monitors designed for the RC guys ?? https://www.goblinhobbies.co.za/digital-battery-capacity-checker-tester-cellmeter-8-lipo-battery-discharger-balancer-rc-servo-tester.html https://www.goblinhobbies.co.za/charger-and-power-supplies/charger-accessories/isdt-batterygo-bg-8s-smart-battery-checker.html Just wondering if you can keep then permanently wired in or do they draw current unequally from the cells ? Perhaps other issues when permanently on

Just double up to get more capacity - you can also just get 50Ah cells and put in parallel if you want 200 AH

Set of 3 for sale. still with original packaging , balance of 5 year warranty - 2023 remaining . R1850 .

Can you get away without a BMS if you do the inital balance well and then manage max /min voiltage with the victron charger and perhaps as a victron disconnect.

Need to build up a 16- 18 cell Lithium battery pack for my Victron MP1 - however was considering adding an extra cell or two in case one or two go rouge after a few years . The problem is will a BMS be able to handle a missing cell ? or will you have to use say an 18 cell BMS initially and then replace with a 16 cell one if in the case when 2 cells go off. How else do you manage this possible scenario?

Can anyone confirm where these batteries are made? I suspect they are Chinese no name batteries branded here in South Africa to Omnipower

Are you able to show a screenshot of the battery display on the Portal ?
