    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.

    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)

    That is correct.. although i have seen 10mm used on a 60amp breaker over very short distances. I still prefer the 16mm...

    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.

    Sorry, but why would you install it like that, inverters should be installed properly. 
    To answer your question, the breaker will not protect your inverter. The inverter electronics should pop long before the breaker trips.

    Jaco De Jongh got a reaction from Youda in What does it means if the red Led "ALM" light comes on   
    It will happen every 48 or 72 hours (Cant remember ) if you dont discharge your batteries. It does happen in battery backup systems without PV panels and self consumption. The alarm is not serious, but it remains annoying. I found a site a while back explaining what in the firmware causes this, bu cant seem to find it now. 
     
    EDIT: Wait here it is. its under the Victron Q&A section.

    Jaco De Jongh got a reaction from Louisvdw in Type of roofing recommended for solar panel installation   
    I like to tinker and mess with bird brained ideas, all for the sake of just knowing. 
    One summer some time ago i mess with the idea of cooling my panels with installing a pipe with sprayers on the top end of my panels. My panels were adjustable so i had them on the correct angle for the specific time of the year. I chose a few very hot days up here (Ambient in the mid 40s), waited for for peak period (Between 11H30 and 12H00) and switched on all the loads in my house. I compared the PV production before and after opening the water. I had 12 x 260 watt panels connected. 3120Wh and could record a 240-250 watt (7.7-8%) increase in production with the water open. The smallest pump I could find with the correct head and flow ratings were .25kw so my conclusion was that I would gain nothing by cooling the panels as my pump would be consuming the extra generation. (although the test was done with municipal water, so no pump needed, i planned to install a pump and use water from 2 x 5000 l tanks as i did not want to wast municipal water.) 
    The test was repeated some time later after adding another 12 panels and mounting them on the roof at a fixed angle. Now with 6240 whp on the roof there was an approximate 450 watt increase in production and again with a bigger pump (0.37kw) it did not make sense to cool the panels. 
    I messed with this idea for some time, but decided its just not worth it.

    Jaco De Jongh reacted to Coulomb in What does it means if the red Led "ALM" light comes on   
    I wonder if you could set up the inverter to do an "equalise" charge every 2 days (maybe every 3 days would work), for just say 5 minutes, to top up the battery and prevent the alarm. Just set the equalise voltage to be the same as the absorb/CV battery voltage setting.
    That way, the red ALM light will only ever mean "serious fault, don't ignore".
    Alarm red light for "sleep mode" is a terrible user interface.
