    CSIR battery

  2. HI Leonc quick post as I have hunting clients here. Do you have a communication cable between Pylons and ICC device?

    I think @plonkster knows the owner.

    Same two clowns look like they are headed to Hungary now. https://rightoftheright.com/hungary-welcomes-white-south-africans-fleeing-black-violence/ They don't have the look of folk that work outdoors.

    UPS and Solar battery choice

    Each battery module comes with its own interconnect cables and communication cables. One has to order one cable pack per Pylontech stack (R295 VAT incl.). The modules are R14350 VAT incl. The neatest way of installing them is inside a 19" server cabinet. A client of mine has made a rack using square tubing. Otherwise the is a bracket system for mounting 2 Pylontech modules which is a little over R400. Jip both Infinisolars and Axperts are on the compatible inverter list. Victron, Goodwe, Studer and Imeon are also on the list.

    Pylon have their own BMS and Axperts are one of the approved inverters to be paired up with a Pylontech.

    Eskom strike tomorrow

    Over the weekend there was cable-theft related outage in Irene affecting 1500 homes. We just don't hear about it.

    Extra solar panels Axpert

    Welcome Colin Most SCCs can be oversized by 20-30%. I have 3kW of panels and was considering installing a 5th string to take me to 3.75kW of PV. I have bought a 2nd Axpert so in a effort to have a more robust system I am going to parallel the 2 inverters and put 1500W of panels on the second inverter so I have abandoned the idea. Solar systems in Australia and the US are often oversized for the very reasons you present and in some cases legislation limits them to the size of inverter one may install. The only South African I know of who has oversized an Axpert's array is @Sidewinder who had 3750kW of PV. As far as I know it was very successful but he too has expanded and paralleled two Axperts . I wonder if @Sidewinderand @viper_za are distantly related?

    Victron BMV 702 - No Power?

    There is a TTT fairy (related to the Sandman) that comes and sprinkles it at night. Sorry I OD on kid's movies over the weekend. Looks Like this weekend is going a repeat process with the cold weather on the way.

    Land Expropriation without Compensation - Truth and Fake News

    Hmm I doubt this is a legitimate website. Author is either a one article wonder from Russia or the true identity of the author is South African and deliberately obfuscated. That been said several of my wealthier farming friends have invested in Georgia.

    Victron SCC.

    same as what I experienced with the Axpert and AGMs and Axpert and Pylons.

    Victron SCC.

    In my case Victron and Voltronic are accepted partners for Pylontech. From discussion it seems the Victron is also prone to overvoltage (something that I know the Voltronic does). My solution is to run the Pylons 0.2V below the recommended 53.2V - a trick I learnt from our favourite Blue Goto Guy.

    Victron SCC.

    I have canned the idea. The Vicron kit is just too expensive. I would need a 250V 100A unit which is north of R10k. I will go with doubling up the home run and two combiners. As soon as I complete my additions I will be totally off-grid. I will still be able to charge via the gennie but my battery bank should be large enough to go through the night with 30-40% SOC on Lithium's which is going to be a wonderful experience. If I had gone through with the Victron SCC the Victron, Axperts and battery bus bar would in effect be the same node so on would be using Solar rather than battery during the day. I would lose the Axpert's Solar balance capability but with the Lithiums able to accept 100A it would not be a major consideration as my loads would invariably be below 5000W.

    Goodwe ES 4.6kW Hybrid Inverter (4.6KW Backup)

    I have had trouble but the Wifi is weak where the install is. Addition: There is a youtube video on how to connect. If you still have trouble I will assist.

    Mecer 5kva inverters - want to run in 'SUB' mode

    Any discharge greater than 1C is thought of as "fast discharge" . Anything below 0.5C is considered "slow" so I would try stay below 0.5C.
