    Jaco De Jongh reacted to Czauto in Victron experience....blue stuff is getting me red around the cheeks!!   
    Hi guys, 
    Everything solved. I contacted victron's sales manager (if i'm correct), Gerrit Tromp, and he sorted everything out in a matter of days. I sent the Multiplus back to my supplier and no more than a week later it was repaired (actually repaired this time), under warranty and is now working perfectly. 
    In the time i was without an inverter and had to use my generator more often i decided to automate it completely. I ordered a Linixe generator controll module from Aliexpress and less than 14 days later, at a total cost of R927, it was delivered to my door. I also acquired a proper 63A automatic transfer switch and installed everything when the Multiplus came back last week.
    Now, when grid power fails, the Multiplus takes over the loads (system is used as UPS with no solar and small 200Ah battery bank). 
    What's lekker now, without any user intervention, the Multiplus starts the generator as soon as one of the conditions are met (battery SOC, AC loads) and the transfer switch switches over to auxilary power (generator in this case)
    As soon as grid power returns, the transfer switch goes back to normal mode and the Multi stops the generator after the set delay time is met. 
    Setting are different for "silent hours" so if grid supply should fail through the night, the generator will only start if it's really needed. 
    This is a really great function and i wanted to utilize it for a long time. Glad it's done now. 
    Thanks Victron. I now realize again why i've converted to blue, even while you (or rather a supplier) made me red around the cheeks for a while. 
    And like always the forum did what it alway does with members replying almost immediately. Thanks guys. You rock!

    That is not the way Victron operates. I will PM you the details of someone you can contact at Victron, He will sort you out. Victron themselves will not tolerate something like this.

    Jaco De Jongh got a reaction from TJ Botten in Installing a Ziehl 101E Anti-Islanding Relay (SA Settings)   
    Just a few things to remember when installing a Ziehl 
    You will need the following:  AND One or two 63A contactors  
     
    Install using the following connection diagram.    Please remember to bridge L1 - L2 - L3 when single phase are used.  Return wires (Feedback from Contactors) are not required in SA. I have used 48VDC to power the unit, but you can can chose to use the grid voltage. I have used grid voltage to switch the contactors.  I have Chosen 63Amp Din rail mount DB contactors (Schneider)   
    Putting the unit into programming mode: Switch the supply on.  Look at the following picture.  The unit comes with the seal not in place.  If the Led between the 2 locks are Red, slightly lift the key cover and turn it 180 degree. While turning you will see a Small blue pin like switch behind the key cover.  Use the key cover and press down firmly on the blue pin for 2 seconds.  The Led should turn to Green now.   Once the LED is Green you can continue with the configuration.   
    Configuration: There are 2 Programs to chose from PRG5 is used for 230Volt Phase to Neutral, 1 or 3 Phase PRG6 is used for 400Volt phase to phase systems with no Neutral.  Press the UP arrow 1 time to display "InFo." Press the RIGHT button 5 times to display "PR 1" Press the UP button till you reach "PR 5" or "PR 6"  Press the RIGHT button 1 time to display "no" Press the DOWN button 1 time to display "YES" Press the Right button. The Device will reset and start with the new program.  Every time a new program is selected, all the settings revert to the default settings.  Changing Settings:  ONLY after you selected the relevant program for your installation, you should continue to the settings.  Press the UP button 2 times to get to the first Menu on the Settings LIst.  Use the Right Button to Scroll through the 5 settings of each Parameter. Use the UP and Down buttons to change the setting to mach the settings on the list.  Once done with all 5 settings, use the UP button to scroll to the next Parameter on the list.   The settings for South Africa are as follows.  Once you done, remove and re-apply the power, the unit will go through a 60 Second "self check" that might be followed by another count down.  Once that is complete and all conditions are within spec, the Contactors should energize.  Once you are satisfied with the settings, press the blue pin till the LED turns red.  Apply the seal, but dont crimp it till you are sure no one wants to check your settings.

    Jaco De Jongh got a reaction from Anonymous in Series String Mystery   
    One other thing that I just thought of. The frame with the JA's had wooden legs and a steel top that was in contact with the panels. Sometimes if I touched the steel it shocked me. Went through the wiring and could not find a reason for power to be percent but did not make much of it. 
    Have anyone heard of a panels Isolation breaking down at higher voltage? 
    I am going to test that when the new panels arrive. String all of them up to the inverter before I mount them on the roof. 
    Want to see if the higher voltage could have been the cause of one panel partially failing.

    Jaco De Jongh reacted to PJJ in Tesla Powerwall vs Pylontech (or similar)   
    I think so too.
    At R167K its about the price of 5 x US3000's and a 8000VA Victron Quattro.
    The Quattro obviously has a bigger inverter (6.5KW) and another big benefit I think is that second AC Input.
    And then there is just the chemistry differences, NMC cells will have a lower cycle life compared to Lifepo4.
    So with those things considered, I will still go blue

    Jaco De Jongh reacted to MongooseMan in New to Solar - Advice needed   
    I can tell you what I'm doing now, since I'm literally in the process.
    I spoke to @Jaco de Jongh, a highly recommended installer. I told him what I wanted, at a high level, he asked some questions then sent me a quote. I then had lots more questions, and we went back and forth on Whatsapp for about a week, tweaking stuff.
    Now I have a final quote.
     
    With that information (and some help from @Tariq  ), I can mostly complete the CoCT form. The rest, I send to Jaco, and he fills in (technical details, diagrams, etc).
    Then I'll submit that to CoCT. Tariq reckons his approval took about 10 days, so hopefully in that ballpark.
    Then I'll get it installed, and apply for the commissioning with CoCT (again, hopefully about 10days).
    Then I'm done.
     
    Hope that helps, @Tariq can correct me if I'm wrong anywhere.

    Jaco De Jongh got a reaction from RikH in How to convert a (grid tied) Sunnyboy into an off-grid   
    You can of coarse connect it to the output of a 3kva Victron with batteries. The PV inverter wll  then take the place of the MPPT in the system , that should be the most effective way of doing it.. 
    Doing it that way, you will even harvest the sun while the grid is off. 
    If the unit is too old, and without Sunspeck, you would need a Carlo to tell the ESS what the PV inverter is generating. (it is needed for control)

    Because this is a monitoring device and not a load, I use a 2.5mm neutral wire from the load side of the main breaker/Neutral bar (Before the inverter) to one of the 2 poles. No fuse needed as non of the other neutral wires in your board are fused.
    It literary only gives a return path for the current that is drawn by the electronic circuits, and even in the highly unlikely, very slim, 1 in a million change that a dead short might occur within this device.. the electronic circuit should fry long before it reaches the 25Amp rating of a 2.5mm wire.. 
    This is just my 2 cents worth...

    The inverter size. Your inverter is a 3kva/2400watt. In this case your load seems to be a resistive load, so the 3000va will apply. It will take from the panels what it can and add from the batteries to make up the 3000va (Rating of inverter) - losses. The balance then has to come from the grid. 
    3289 (Load) -2267 (PV Production) -445 (Battery) -837 (Grid)  = -260Watt (conversion losses). 
    If you had a 5kva unit, everything in this case would have come from panels and battery, nothing from the grid..

    Very professional and neat installation love the attention to detail some of the best I have seen to date. Also love to see Sunsynk installs great Idea to mount the battery box on sturdy brackets looks much nicer than batteries on the floor. Also love the galvinized pipes used for the solar cables and earth cables really rounds everthing off. Even the Solar panels are mounted perfectly. I am impressed.

    Jaco De Jongh reacted to yani in New software for Inverter/Pylontech monitoring and control   
    Hi guys,
    Just wanted to present to you a new Windows' software tool that we prepared for monitoring of PIP/Axpert inverters and Pylontech batteries. It supports many compatible inverter models. It can work with parallel configurations as well. This was actually the main reason to write the software because a few months ago I upgraded my system from single to 3x inverters and the "pi" solution did not work correct anymore.
    The software can control switching between battery/grid mode based on Pylontech SOC, and also can control Pylontech max charge current based on the request coming from its BMS. The software can also upload data to emoncms server. 
    Currently the software has only basic reporting, but all inverter/pylon data is stored in local database and we intend to add more reporting options in future.
    We also added a "console" screen where users can manually send commands to Inverters and Pylontech.
    The communication with inverters is by USB or RS232 connection. In parallel setups each inverter should be connected with separate cable. I chose this method because reading parallel data from a single inverter is highly inaccurate and slow (at least in the setups where we tested).
    The Pylontech batteries can be connected by RS232 (console port) or RS485 (to the dedicated RS485 port). 
    You can download the software at http://www.multisibcontrol.net . It is absolutely free now.
