  1. I have two 200A JBD BMSes for sale. Bought them through TTT who imported them. Since cancelled my batt build as I picked up to good condition BSL 6.4's. They have bluetooth built in and also has RS485 port, comms possible with Victron if you load a driver on Venus OS. Wanting to see if I can get R2000 per bms..., will courier anywhere in SA...
  2. No 22000 / 1.15 = 19130 You can just buy it without a tax invoice, so then the price is just R22k or make me an offer. It's a private sale in that the company is not a solar company or anything, but I bought it on company books...
  3. Not sure why I can't edit my posts but Price to come down to R22k vat inc.
  4. I have got one Victron Multi 5kVA for sale. R24 000 Vat inc Unit was used in a 3 phase UPS setup for about a year. Still have 3.5 years left on warrantee confirmed by Victron SA. The Inverter is still spotless and in "as new" condition!! I bought the set of three for an installation only needing 2... so selling off the extra one. Vat invoice will be supplied with sale.
  5. Super excited, went to pick up my 3 5kv multiplusses and venus gx from the couriers... Remembered now, the unit has been used for a short while as loadshedding backups but not used hard at all, and they still have bulk of the warrantee left, so happy with the purchase... A huge shoutout to [deleted by mod, commercial suppliers are to register with Powerforum] for an awesome deal on these, and sorting out the courier costs!!
  6. So a brief background... I've been on the forum for a while, although relatively silent. I almost bought a solar installation company in 2012, but things turned out completely different, maybe for good but still my keen interest in solar was still always there... In 2014 I had some capital and was planning to do a solar install but then 2016 the decision went to drill a borehole first, so solar was delayed again... mid 2020 I decided to take on the solar once more, and this time it looks like things will happen. My budget, around R120k for starters, then we'll see over time where we go. I planned initially to go for batteries with warrantees, but am now strongly thinking about building a bank myself as I can about double my capacity with the same money... Planned system: I planned a system with a 8kw Sunsynk, 7kw PV and 10kwh batts for starters. Then last week an add popped up for three 5kva multiplus units. A year old but never been installed and still under warrantee. So I picked up the units for R15k ex vat each, including a Venus GX. And there goes my budget... haha So I'm picking up he inverters from the couriers this morning. Secondly I am busy with a deal for a smartsolar 250/100, which will hopefully go through today, holding thumbs. If i get the mppt then I'll stick with that for the start. So this weekend it will be making lists of hardware needed. Current planned day for switch flip is 31 March 2021... Let's see how it progress. I will update the thread regularly for those interested and also I'll appreciate if those that have done this can give me pointers and warnings where they see needed, if they so wish..
  7. I'm just hanging on for a day or so with the order to wait for someone else to add to the order to get courier costs down... send me a message or a mail to [email protected] with what you want... Will take it from there...
  8. As far as I could see the Shelly EM for DB board monitoring does have one contactor control switching possibility but you don't need to use it to measure power. You use p1 and p2 to connect your clamps, so you can measure two channels, which you clamp over the wires you want to measure. So no switching done on the channel you are monitoring. The contactor control is handy to have, but is a seperate function to the power monitoring. I will still keep my current cost power monitor to visually see what is happening... but will use the shelly for the accurate logging. The Shelly PM with the relay is for single smaller appliances and not for the whole house application.
  9. Still planning to order end of this week... If there's still someone that wants some shelly stuff...
  10. Very aware that it can quite easily be done but I have too many other projects, so want to get something that I can connect right away with an existing portal... Want to relook my usage profiles and shift it around a bit before starting with my final solar system planning to implement later this year... But before that my water filtration system, the building and plc programming, is taking up most of my time... Just too many projects currently...
  11. Posted a group buy thread with cut off dates when I'm going to order if anyone wants to club in. I'm going to order for myself in anyway, so let me know. Shelly Group buy, direct import - Group Buys - Power Forum - Renewable Energy Discussion @Singh GP @Vassen @PaBz0r @langou
