  1. Hey all Is anyone else running a 3D printer on their solar setup? I have an Axpert Clone 5KVA 4kw inverter and a Tevo Flash 3D Printer with AC Heatbed. The problem I'm having is the heatbed is causing the fluorescent lights in the house and garage to flicker, only when on battery mode and solar mode. On bypass it doesnt flicker and also when bypassing the inverter entirely it doesnt flicker. Any idea what could be causing this, I'm assuming the inverter is not liking the AC heatbed.

  2. We had the idea of disassembling them but the batteries are only 1 year old, so we would effectively loose the remainder of the warranty.
  3. So the batteries have their internal BMS and from what it seems like, there is no known way to communicate with it at all. There are talks of a software that will be released in the future but other than that, nothing can communicate with it. Currently the inverter is set to fully charge the batteries and then change back to grid once they hit 48v. The issue being is that we dont know what SoC 48v is. For all we know it could be anywhere between 40% and 5%. Monitoring remotely and adjusting the inverter to change over at the correct SoC is most ideal.
  4. Hi all so we have the following : 9 x Canadian Solar 360w 1 x TheSunPays 5kva / 4kw Axpert Clone (soon to have 2) 2 x TheSunPays LiFePO4 100AH 48v batteries (possibly expanding to 3 or 4) Now as it currently stands, the batteries can not talk to the inverter. The batteries can also not talk to ICC, the inverter/s however can talk to ICC. So my question is, if we get ICC, how can we get some sort of reliable info on SoC from the batteries to the inverter? I have been reading around and it seems that installing a Voltronic BMV-702 will do this? Has anybody tes
  5. Would you possibly be offering comms with inverters and batteries from TheSunPays?
  6. Would you be able to pm me those comms with the ICC team? I have a 4kw/5kva Sun Pays victron clone with 2 x 4.8kw lithium ion batteries (their older ones without the screen) and we were told that the software cant communicate with the inverter and the batteries. The problem being that there is no comms between the inverter and batteries, ICC would be great for this. We've been waiting on Sun Pays to release a firmware that can communicate.
  7. Did they advise what was wrong? Our inverter is doing the same, relay clicking and screen flashing. Its just out of warranty, we sent it to the place we bought it from for assessment. It arrived there and worked fine, today they tried switching it on and it wouldnt power on, relay clicking and screen flashing. They think it might be the control board or the motherboard so they are testing that now. Problem is the control board is R980 and the motherboard is +- R5000.
  8. Well it isn't necessarily dangerous considering that fuses were used for many years before breakers. Additionally most electrical equipment has an AC fuse installed. Another example is all plugs in the UK have to by regulation have a fuse in the plug itself. AC fuses aren't anything new, it just isn't widely used here in South Africa which is why it seems quite odd. The main pro of using a fuse is that they tend to blow at their rated amount where as a breaker tends to trip 3 - 4 times its rated capacity. ElectroBOOM actually has a video that touches on this. He put 100A throu
  9. Judging by your response, it would seem that was the response from the installer, sadly I did not see it before it was removed. I would like to thank everyone for the advise provided. As for the installer, I intentionally did not name or shame you, I intentionally left out your branding stickers that you stuck on the inverter and the DB board, I removed my 1 star review of your business when you begged me to, I am sorry that you do not see me as a grown up and that we did not have the opportunity to meet, I am actually an incredibly busy person as I handle the international distribut
  10. So just an update. We had another company come out and correct the install. All 3 strings are now wired into the DB board (6 wires total), each line is fused and then passed through an isolator. Surge protection was also added on both the solar side and inverter output side. This fix up cost an additional R12000, the previous installed had the cheek to ask for his old equipment back since we are no longer using it
  11. Hey all So we overloaded our Axpert clone inverter one too many times and it kicked the bucket (currently in for repairs). We purchased another one though and intend on running them parallel to increase our overhead. Now what we would like to do is install some sort of overload protection on the inverter output. The idea is to have something similar to a PV fuse as its fast blowing, this would basically limit the inverters output and should this be exceeded, the fuse would blow before the inverter overloads. We have looked into the idea of using normal breakers but this woul
  12. I can confirm that currently there is no way to communicate with these batteries. We've had 2 batteries for just over a year with no way to communicate with them. Apparently they are developing a software for the raspberri pi to be able to communicate. As I understand, no inverter can communicate with these batteries. Inverters can however communicate with their new batteries which was released a month or 2 after we purchased these batteries. Incredibly frustrating to drop R50k+ on something that we cant use properly. After months of mailing with them it basically came down
  13. Thanks for your response. It looks like 3S3P, we peak at 2.8kw at +-120v. Each panel nominal voltage is 40v hence the assumption. The strings are combined on the roof at the solar panels. We have a single positive and single negative which then comes down from the roof to the isolator switches. Correct, there appears to be no surge protector, is this a requirement? The electrician was supposed to install it all to 'code'. I've attached an image of the cable where info is written, I'm not too sure what the thickness is because at one point it marked "6.00" and another point "MM
  14. Hi all So we've had a solar system for just about a year now. In December I noticed a burning smell in the garage where the solar system is (isolator switches, batteries, inverters and DB boxes). As I was soldering that day, I assumed I accidently burnt something with the soldering iron and just left it. Suddenly solar power was lost and I investigated further. 1 of the 30A fuses inline with the solar feed had blown. We replaced it thinking it was a manufacturing defect. Shortly after that the smell became worse and I noticed what looking like melting on the 1 isolator switc
  15. Hey all So I've built a 3s13p 18650 battery packing using 39 x Panasonic NCR18650PF 2800mah batteries. They are connected to a BMS. Technically the pack should have 36AH of capacity The intention is for it to run a router and tv at the S/O place. I am currently testing the pack by running it through a few charge and discharge using a small Turnigy Accucell 6 charger. Now, I would like to build a system so that it functions similar to a UPS, just with a lithium ion battery pack. I've seen a few videos of this being done but there are a few problems with just a direct swap
