May 27, 201610 yr Got these beauties today Just need advice or any tricks..... before I attempt installing them please Batteries 8 by 6v J305 USA R700 each
May 27, 201610 yr That is ridiculously cheap. Well below supplier cost prices. Sent from my SM-A500FU using Tapatalk
May 27, 201610 yr Author I have a very good mate, that gets me super staff prices........ what would one pay for this?
May 27, 201610 yr About R1200 +VAT for the end user. At R700, it is WAYYYY below dealer prices that I have seen.
May 27, 201610 yr You asked ... 1 hour ago, Camel said: what would one pay for this? I am waiting same as you, for a answer, for 4 x 6v ones.
May 27, 201610 yr Author Surely someone has done it on 6v batteries. I am just going to act like two batteries are 1 12v battery.....
May 27, 201610 yr Yes I did it on my 6v batts just grouped them in pairs with voltages as close to each other and that made the 12v "batt" then just follow the wiring diagram sent with the balancers . Just check on the voltages of the pairs every now and then
May 28, 201610 yr Viper_ZA, yes, you said so before. So 1 x BMV balancer with 4 x 6v batts, (2 x 6v to make 12v) is then fine? Thing is, I swap my batts every few months around, being only 4 easily accessible ... EDIT: I want Victron to make a 6v model.
May 28, 201610 yr If Camel can provide Blue battery balancers to us Forum Members, at around R700 + courier ... for me it is a no-brainer.
May 28, 201610 yr Maybe late to the party, this is how to connect. for 6V you could do this: in theory it should work. The units only apply a load so really it should work fine like this.
May 28, 201610 yr Author Not late at all. Have not got to it yet. Still trying to work out how to keep it neat and tidy....... the bottom picture users 5 of them?
May 28, 201610 yr That's just theoretical for balancing 6V batteries with 12V balancers, Before the argument begins... lets say Bat 3 is slow to charge Bal 1 will load between 0-12 Bal 2 will load 12-24 Bal 3 will load 12-24 bal 4 will load 12-24 bal 5 will load 12-24 Admittedly its a little more complicated to figure out what will happen. But if you think about it each balancer only cares that its own banks voltages are the same while charging.in the scenario where one battery charges slower the rest must be slowed down and that happens just fine. Imagine not batteries but drums of water with a bunch of level valves. they'll end up the same volume because science.
May 28, 201610 yr Author Thanks, it makes sense. Do you really think it would be worth getting 2 more ? More wires to the system too
June 1, 201610 yr Author You going with 3 or 5 ? If I have time I will put them on this weekend going with 5 balances
June 1, 201610 yr Let me know how this goes, I might have to add 2 more to my system but really saving up now for 3 more panels to run the geyser on PV during the day
June 1, 201610 yr Author Will do viper. Just out of interest I see you running 2 strings of 3 panels how is that woring for for you? I have 3 strings of 2 panels. Would it be better for me to go the same? I have the same Axpert. what MM wire you runing on the strings?
June 1, 201610 yr Thanks Camel I'm also interested in what 2 panels per string is doing. Not seeing any problem on my system, see PV maxing out at +-1550w (heat, angle etc) on normal days and did see 1790w on cloudy days before. Using 10mm² for the strings to the combiner box and 16mm² from combiner box to the inverter +- 9-10m run. I don't like voltage drops Update your signature so we can see what's cooking http://powerforum.co.za/settings/signature/
June 1, 201610 yr Author I have only seen my max at 1200watts on the 48v one. Signature updated..........
June 1, 201610 yr That's not a lot, wonder if it is the 2 per string vs 3 per string making a difference
