November 30, 20169 yr Author Hi Hein, I always make use of either DHL or FedEx. The norm from China is between 2 and 4 days and I rather pay a little extra and get the things quickly. I only placed this order Monday afternoon at 16h00 and it will be at my doorstep early tomorrow morning. The 2*HA02's is going to take a little bit longer as they are still in production.

Unfortunately the place I ordered from (dx.com) doesn't offer DHL shipping. Only registered post. I'll keep my eye on the tracking website. I found a 2nd hand unit (spherical camera) here in S.A that I'm going to buy that I can use till the shipment arrives.
December 1, 20169 yr Author HI Guys, The 10 HA-02 's is on my desk. Total cost R 775.20 incl vat If everyone could let me know what your shipping addresses is, I might be able to deliver some of the units to you. Otherwise I could send it via post or courier to you( Courier cost to be yours) If I make use of "The Courier Guy" the cost to you would be R85.50 for delivery to your door anywhere in South Africa. Delivery would be anything from overnight to the big cities, to a maximum of 3 days for remote areas Please contact me on my email: [email protected] for banking details and your shipping address. Thanks guys !!
December 5, 20169 yr Author HI Guys, Could all the guys please confirm receipt of their HA-02's Just checking to make sure everything is completed successfully Thanks - Chris
December 5, 20169 yr Should be at my office tommorrow AM. I wasn't in this afternoon. Thanks again - great speed and service!! Regards Mark
December 6, 20169 yr 1 hour ago, SolarNoob said: What do you guys think is the best way to connect these? If you have a BMV 702 I would connect 1-4 and 5-8. If there is an imbalance you will be warned by the BMV mid-point reading. Ideally you need 1 HA01 to link the two ½. Any combination that has batteries on either side of the midpoint could still have an imbalance that goes undetected. I the batteries in one balancer string is 0.5V lower than the other you will not notice since of the 4 batteries 2 will be one side of the midpoint and two on the other. I thought of using the 12V functionality and pairing them 1 & 2, 3&4, 5&6, 7&8 for one balancer and then 2&3, 4&5, 6&7 for the other but that leaves 1 and 8 vulnerable to imbalances. Perhaps someone clever can come up with a good solution.

Now to see if there is a difference running 1x HA02 (wired in Parallel with fuses) or 2x HA02 (1 per bank) PS: I have removed the large cable between the midpoints and now added a smaller fused (5A) cable as per BMV installation instructions.

December 6, 20169 yr 50 minutes ago, Mark said: How about: 1-3-5-7 and , 2-4-6-8. ? I am worried about non sequential attachment. The HA01 has 3 wires 0V 12V and 24V. You may find that the positive of one balancer set of wires is common to the negative of the next internally. If you mix and match the balancer architecture may assume to wires are at the same voltage when they are not. Chris is in contact with the manufacturer why not ask them. Addition: If 2-4-6-8 is slightly lower than 1-3-5-7 you will never pick it up as 2 low batteries will be on one side of the midpoint and 2 on the other and so your BMV will happily return a value of balanced even though patently they are not.

I have not received mine yet and need to perform a few tests before confirming the above, but according to the Chinglish on the web it seems that the 4 sets of cables can be connected any way you like - none of them seems to be connected internally, unlike the HA01's connections. The equalizer is not affected with battery connection way, no matter in series or in parallel, both can work.
December 6, 20169 yr Author I will send an email to the manufacturer and ask them what do they suggest and how are the units connected internally. Will give feedback soonest possible? I am sure I saw somebody on the forum ask about high current & high voltage DC breakers and suppliers for this. I am busy with another supplier on these units and and it looks like being very much cheaper than what I can get it locally as well as being frequently available. I am ordering a DC breaker 250amp for my battery bank as well as a DC 1000v 63a for my solar panels. DC Surge arrestors also available If anybody is interested, I will have the final prices by tomorrow morning. Cheers
December 7, 20169 yr Hi Chris, I would also be interested in DC breakers for my battery bank and solar side. Thanks.

December 7, 20169 yr Author The brand is Feeo Approximate pricing is 200 amp dc breaker 550v = R 675 +vat 63a 1000v Dc breaker = R 390 + vat I should receive mine by next Monday latest and will give you feedback on the quality. I have purchased surge arrestors previously from these guys and were very happy with it. Cheers
December 8, 20169 yr I have seen the Feeo stuff, not bad at all. Not Noark quality but it's decent for the price you pay. http://www.feeo-solar.com/dc-circuit-breaker/
December 10, 20169 yr Author Christmas present coming for Zupta I have started with my installation today, and got the first 16 panels fitted. The Imeon9.12 is fitted and I should receive my power box Monday for fitment. I manufactured my own brackets for IBR fitting, as I wanted at least 180mm clearance between the IBR sheeting and the panels. I also used 100 x 50mm lip channel as purlines and fitted Unistrut u-channels on top for fixing the panels. The brackets and lip channels is powder coated and should last many years. ( I hate any paint work ! ) I've got the brackets coated with a mix of all the leftover powder ( all different colours ) and it actually came out nearly black, but at a very affordable price!! All of this made the frame durable, although fairly inexpensive compared to all the different quotes I;ve got. Many thanks to all the forum members who assisted me so well with support, advice and sometimes just being there for me when I felt down !! I have posted a few pics. Open for criticism and suggestions. Still a lot of work left for the next two weeks. Cheers Guys !
December 12, 20169 yr Author Need advice on wiring layout for new DB! Attached please find proposed layout for my existing and new Db's. Anybody with advice where will be the best situation for installing a switchover. I need to be able to switch all the buildings back to the grid, in case I have to disconnect the inverter. Thanks Guys!Switchover.pdf
December 12, 20169 yr Author HI SilverNodashi The vertical brackets manufactured and powder coated = R 60 each = 30x 60 = R 1800.00 14 x 3m purlines @ R130 + powder coating @ R150.00 = 280 x 14 = R 3 920.00 16 x 41 x 1.6mm Unistruts @ 195.00 each = 16 x 195 = R 3 120.00 100 M8x60 Stainless steel Security Torx screws = 100 X 9.70 = R 970.0 100 x M8 30mm square stainless steel washers = 100 x 2.41 = R 241.00 Total cost excluding labour = R 10 051.00 Cheers PS. The structure is for fitting of 2 sets of 20 panels each, one facing Northwest and one South east.
December 14, 20169 yr Author Hi Guys, I really need some advice on a switchover switch I would like to install, to bypass the inverter and keep the grid going without the inverter being installed. I have attached a layout of the wiring I was thinking about, but need the experts advice! Is there anybody out there that can help me? Switchover.pdf
December 14, 20169 yr Chris I use one of these (40A) and plan to add 3 more when I redo the DB. One for each phase plus an extra for outbuildings... http://www.hager.sg/energy-distribution/control-signaling/modular-isolating-changeover-switches/5264.htm Regards Mark
