That's not a lot, wonder if it is the 2 per string vs 3 per string making a difference

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/

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

Wrong again, there is a option to limit it at 10A for say 100ah bank but they recommend you use a 200ah bank minimum. If I have gone with what was not recommended and used the 100ah bank and installed 3000w of PV It will still work but I would still not have matched what you stated as things that need to match? Yes it can TTT not necessarily wrong but your statement cant be applied to all setups

Yes this is possible, but minimum bank recommended for 5kva units (3000w Solar) is 200ah So you would limit it to 20A

Will have to check that for you but I am limiting my current to 20A for the bank +- 1100w going into the batts according to the BMV

Fixed it for you 2 strings of 3 panels

You keep saying this and this is not true for the Axpert boys, the thing has enough settings to be safe by having a limit on your charging current and still be able to use the rest of your PV to carry the load

Got me a few this morning. Got to hurry if you want to grab them the people were already parked outside the parking lot

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

Clutter?

@Alec Swanepoel I can mail you a copy of AICC from Jaco PM me your email address and I can mail it 5.28Mb For the BMV I'm sure someone on the forum can help out with good prices Found a BMV 702 + cable special R3300 https://re-volt.co.za/Store/index.php?route=product/category&path=69

@The Terrible Triplett Answer me this, why is it that Victron can charge you if you take the cost of the BlueSolar 150/70 charge controller and you want the use the CANUSB interface cable it's more than half the price of the charge controller. What makes this cable so special? Can say the same for Ve Direct to USB

My problem is in actually getting the item here thanks to our lovely post office. After a couple of orders of a few things that get's lost here it worked out more expensive than it would have for me anyway. Luck of the draw lately with getting your package or not. Some you get some you never do. Courier is just way to expensive negates the saving

I think when you look at solar and running on batteries at night every few watts you can save kind of makes up for the price

Get the network cable from a PC shop

Yeah that's the way it is, the only variety you will get is in the prices not the items

Mine works looks real good Manie

Dink hulle goed is heeltemal free

Have a look here at Rubicon for fuses. I paid around R25 for PV fuses might have been even less rated to a 1000v DC https://solar.rubiconsa.com/category/34-solar-fuses also fuse holders https://solar.rubiconsa.com/category/35-solar-fuse-holders The fuse they recommend for the battery bank 48v 160A is a little big (7680W) I will cry if my batts do that. Also the fuse for PV seems to have a low Amp rating I'm sure your panels are rated more than 6.8A. Fuses should be rated at 125% of the current to avoid nuisance blowing

This in my eyes is a design fault on your frame and kinda defeats the purpose trying to extract the maximum out of your panels then? We not saying it wont work, what we are saying is the cost of doing this + the wasted space you have now with trying to keep the panels from shading on each other vs the cost of just adding a few more panels (Cost is the key point)

talking about the space lost and the cost of the tracker vs just adding more panels to your existing install to make up the power lost. The only true thing the tracker probably brings to the table is longer hours of sun, but then again is it worth the cost?

Do you have dimensions of this frame, I see a huge space lost between the panels making up mounting space for extra panels if it's not used

What's the cost of doing a frame like this with tracking?

How many banks do you have Manie? Update your signature then it's easier to know Is it 4 x 6v batteries that make up one 24v bank?
