  1. Sorry all, very rough day. We can look at splitting, if we then basically have everything go at once. And from the above replies, it seems all is in order on that front. I will PM you guys separately Thanks all.
  2. Hi Guys, I have my blue system up for sale as we are heading across the pond Multigrid 48/3000/30-50 Bluesolar Charger MPPT 150/45 VenusGX Controller Pylontech Battery 3.6kw (no mounts) - Less than 100 cycles (80% DOD only), health still reports 100% if that helps. 6x 355w Canadian PolyPERC KUMax Gen4 - with rails Battery Fused Isolator - with some fat fuses Cables etc. Link to see it in action below. https://vrm.victronenergy.com/installation/27720/share/0db8810f Purchased in October 2018 from supplier in Centurion, will confirm on warranty transfer Not putting a price on it, reasonable offers would be appreciated. Thanks
  3. 4.4KWh from something the size of a 10 cent coin...pity it takes 5000 years to release that power...And you have to build a house made of lead :)...
  4. On a flight into dark Africa about a year ago I had a chat with a (insert big word title) "mining/mineral expert" , specializing in battery tech research in Africa, around this exact topic. He stated that telecoms are starting to replace with Lithium batt banks, because they don't have that much maintenance, and because it doesn't get stolen from cell towers as there is no recycle value to lithium currently. It's apparently not easy to recycle, and because there is a LOT of lithium resources, we won't run out soon so just use raw materials, So the local scrap yard has no use for the batteries. There may be some high value metals in the mix, like Cobalt and Nickel, but this will possibly be removed completely in the next few years.
  5. Apologies, you are technically correct. but for the price of blue nova...Who can afford a second unit anyway, One can survive on a single Kidney, but no kidneys...it's gonna be a bumpy ride
  6. That will make it quite unique, and very very useful. Especially for upgrade purposes. 2x of these 3.5kw jobbies will basically match a Tesla powerwall for half the price. In any event, these units will be a serious contender to replace lead-acid. Like for like (Price per KWh) they are in the same ball-park, especially when comparing 70% SOC to 80% DOD. And less worries about balancing and monitoring.

  8. Hi Antony, Depends on what you have on the equipment, if you keep switching off a DSTV PVR decoder and sensitive AV equipment, that has a mechanical Hard drive in there, which doesn't like instant power drops. That's why we perform shutdown on PC's to get the HDD heads in parked state, and not just skimming across the platter. While I respect your opinion on saving 100w a day, this only means R6 a month at best. Having to replace a DSTV PVR @ R1k a year..would nullify those savings. Just my 2cent
  9. Hi Guys, I had some bad luck last week, my solar system got fried by lightning. And my batts cried after the untimely death of the inverter, came home to a splash pool size of battery "tears" on the floor. I am in the final stages of the insurance claim, and just want some advise and recommendations for replacement. Equipment: 1x 5kw rebranded Axpert II 4x 355w Canadian Solar Kupower PV, 4x 120AH Flooded batts 1x HA-02 - Seems to be toast, as the differences we're massive on the battery bank, and it's not squealing like an angry Mozzie anymore. And then some cables etc. Day time load: 400w base load, plus 1kw, for 4 hours 10-2pm for the Pool pump. The system was sufficient to carry all load from around 8am, to 4pm, where I would switch to utility mode to save batts in case of load shedding, and then Batt mode around bed time. This was quite tedious to manually do daily so a bit of automation in this regard would be appreciated. Evening average around 500w load 6Pm-6AM. Your suggestions would be appreciated on a replacement system, maybe upgrades if there is budget. Thanks.
  10. Hi, Thanks, That's the main reason for swapping the 2 older ones this weekend. So I have 4 fresh ones on the string now. I have read a few posts around that indicate similar issues with the all-in-one. School fees i suppose But with the money I spent and all the forum help, I should graduate soon. Any preferred provider for that balancer? Thanks Theo
  11. Hi Guys, I am getting a weird issue after running fine for a few weeks. My 3rd and 4th battery in series from positive side are becoming unbalanced. I noticed that the 3rd batt was always around 0.5v lower than the rest, and could see it cause issues as it drained much faster, but would pick up quickly aswell, causing the whole setup to switch between grid and battery modes a few times a day. I changed the batteries (3rd/4th) which we're the lowest, with new ones on Saturday. Made sure the SOC was close across all 4 batts. And hooked it up. It was much better, as it ran most of the day off Batt mode, until it kicked back to grid at 48v. I thought it good to recharge from grid overnight to 54v then. They we're happy and at 54v and around 13.5v each on Sunday morning. I switched back to SBU mode, and immediately battery mode, with a little input from solar as it was still early. This drained the batts to 48v again over 2 hours. I charge solely off Solar from here on out, but noticed it only charged for 10mins, before kicking back to batts off 58.8v. Load was 1.5kw average (washing day), Solar 900-1200w, and batts drainging between 5-10amps. It would only be able to sustain the load for 20mins, and then charge 10mins, rinse and repeat. That is definitely not enough time to chage 3 cycles before 12pm, and the batts are way out of sync again. 1. 13,7v 2. 14.5v 3v 12.5v 4. 12.5v So it's back to the drawing board, as the new batts are now behaving similarly. I swopped the front pair and the back pair, and withing 2-3 cycles, it would again change the charge around. Front pair high, and back pair low. I don't have a BMV yet, so I went according to the good old manual multi-meter, writing down the readings every few minutes. Any ideas? Cheers
  12. Hi Guys, I am now fairly happy with my system, although it's seen on here as cheap, (READ: I am paying school fees) it seems to work well :), at least got descent panels it seems. I now want to wire this into my DB, and split the line in from Eskom, so that I power the plugs and lights from the inverter/solar/battery. I have all the power hungry bits on gas already. Don't even own a electric kettle. I don't want to do this part DIY. Can you direct me to someone willing and qualified that can do this part for me? Cheers
  13. Howzit all, So some feedback after a few days more testing. My little 3 year old was sitting on the battery bank on Saturday, and after giving me a hell of a fright because he was messing with the cables, I realized 1 clamp was loose. Tightened the whole bank, and Voila!!! I got 65Amps out at 50% DOD that night. No weird quick drops or anything, it goes down slowly, and charging also comes back up slowly. Who needs a tester, Get a curious little guy to "test" your setup.
