Great videos . Appreciate people sharing their installations so we can all improve on our work. And also learn from each other. I understand some electronics are safe to connect without an earth leakage but its just good practice to have one incase another electrician connects other 'non essentials' items that do require it in the future. I have seen many installations where plugs are on the non earth leakage circuits and people don't realize the danger. Other than that, good install, love the use of a proper ac plug for the Gen. Shielded cable , nice solution too!
What a fantastic guy. I contacted him about trouble with my Sunynk and Svolt batteries. he guided me through everything and it is working perfectly now. He knows his stuff.
Another thing if you using a single rail DB you have to partition the non essential from the essentials it's best to use a separate Db for the essential circuits
Under batt charge enable singal island mode, then from the mainboard, the white middle connector strip there is a L & N, have that go to your contactor then from your contactor into the green inputs
Hi Thank you for the informative videos. Does the changeover switch stay on 2? When there’s load shedding to you have to do the flip the changeover switch?
Good evening Anthony, thanks for videos and sharing your knowledge and your experiences. Anthony i just want to know the spd is it only to protect the inverter and what you feeding from escom on the change over switch, cuase when you feed from the inverter it doesn't include spd. Hope understand what i am trying to say. Thanks again
The SPD is protecting the inverter from any surges or transients that might arise from the electricity Supply company heavy industry equipment switching on and off or flash density From resulting from lighting strike in the area
Looking good! The only problem I see is the wire color you use is not allowed by law. However if you clearly mar the blue and yellow to red and black you should have no problem. Also don't forget your alternative power supply light. You know incase someone who does not know about inverters, works in the DB and does not get electrocuted. All and all looks clean well done
Thank you for your advice much appreciated, on the other colors if you noticed I tape the end of the cable for the other electrician who might not know what's happening, perhaps on this video it was not done.
firstly your videos on installations are the best thanks for all the info you provide. secondly wouldn't it be better to have an earth leakage for both non-essential and essential loads? also i put a NC contactor bonding Neutral to earth for my installation as there was a floating neutral when eskom is down is this correct to do?
Hi I used to put a contactor before now I permanently bond the neutral to earth cable on the Ac protection box to simulate Eskom power supply TNCS and will sort out your floating neutral and your earth leakage breaker will have a reference as well
From the Eskom breaker, the first 2 pole breaker, you go straight to non essentials? IE you bypass the earth leakage for non essentials? Or am I missing something
Hi yes correct I bypass the earth leakage provided that an earth leakage is not required on those items if Sans 10142 regulation allows if not there must be a separate earth leakage fitted to those items as well
Hi there yes the inverter does the switching But have you ever thought of how to isolate the inverter from an installation for maintenance or repairs. look at the diagram in Sans 10142-1 ed1.8, page 357 diagram S3 explains how to wire an inverter to a premises
I need help on that...i connected the input three core cable at the top of the main breaker, then output at the bottom .. With both of their neutral and ground connected to a bus bar...but after turning on the inverter fault light comes on...
Hi Anthony. There are conflicting arguments on whether to bond the neutral out of the inverter to earth permanently or through a contactor relay. Please can you explain the correct way of doing it as some electricians put the relay in and some bond…
Hi I used to bond with a relay nothing wrong it's just that the relay coil may after some time and you stand at a high risk of the earth leakage not activating , you end up having a floating neutral, elevated voltages between neutral and earth causing a further risk of electrocution when metal exposed parts become live. The inverter is a VOV machine, that was designed for the European market, you have to convert its power supply to local regulation requirements which TNCS that's why I permanently bond neutral to earth just Like generators same thing.
Could you provide a code for that generator input, please? I'm assuming the one on the wall is the male side under that cover. I'm going to be using a petrol Ryobi 7900k, which can push 28A. My Inverter is 11kw MAX E with 2 x AM2 batteries, soon to be 3. I want the generator for in case we have unexpected 6 hours of load shedding or the grid collapses to prevent the batteries running flat.
Anyone to answer.. I have a leupower inverter and a elf bulb lithium battery.. When the installer installed he told me the communication cable doesn't matter and it is not necessary he did not put it on.. Everything is working but the inverter doesn't show battery % and on battery type it shows lead acid.. Can i change these options on the inverter without the communication..cabble will there be any problem?
Hi there 20A is for inverter output to protect the inverter from overloading and 40A is for Eskom bypass if not using inverter backup purpose and cable rating size hope that explains well
Hi please share a bit more detail what model number is the Shoto and the serial number of the Lux power on battery settings number 3 what brand type did you select and lastly what type of network cable are using as in pin configuration
Hi there N energy is a generic battery does not have a communication protocol yet as far as know it only manages it's self so you set it up as a lead acid
just a couple of faults . incorrect CB installed in main DB that feeds the inverter DB should be of the same type as original cb's (cascading). Blue is not neutral that must be taped up with black tape Indicator lights with on protection must be installed to indicate what power source is present Socket for generator seems to be female ,that must be male. I would also use the same brand type CB for inverter return cb in main db this cb could also be an isolator type as the cb in inverter db already protects the cable and inverter
You can't use a blue wire as a neutral according to sans rules and you can't cant have 2 pen earth's on 1 property and you not allowed to have 2 wires that is 4mm and thicker in a breaker.

Wow what a video, straight to the point all detail in just over 5 min
well done, thanks for putting it out there as we electricians are all to familiar with nit pickers whom wont even publish their work, you go dude!
Hi Anthony, Great job and installation...but your geyser must be under earth leakage according to SANS10142. Love your videos!
Another thing if you using a single rail DB you have to partition the non essential from the essentials it's best to use a separate Db for the essential circuits
Great video. Thank you. Can you show a video on how to wire up the contactor for the ground neutral bond on the sunsynk. Thanks again
Under batt charge enable singal island mode, then from the mainboard, the white middle connector strip there is a L & N, have that go to your contactor then from your contactor into the green inputs
Segen solar has a detailed guide on this
Hi
Thank you for the informative videos.
Does the changeover switch stay on 2?
When there’s load shedding to you have to do the flip the changeover switch?
Hi yes it's recommended to be on two if it's supplying part of the premises, if for the whole premises you do it vise versa
Nice to see this video! Does one need a 10mm Cable for a 10KW inverter and 50mm cable for the DC side with 2x 5KW Batteries?
Good evening Anthony, thanks for videos and sharing your knowledge and your experiences.

@@anthonymwambazi7390 awesome stuff Anthony ! Are you happy with the Greenrich batteries, head all sorts of great stuff about them
Also neutral wire is used as an earth continuity conductor under the SPD

According to SANS 10142 GEYSER must be on earth leakage
I thought the change over was done by the inverter itself.. do you actually need an external breaker for that ?
Hi there yes the inverter does the switching
But have you ever thought of how to isolate the inverter from an installation for maintenance or repairs. look at the diagram in Sans 10142-1 ed1.8, page 357 diagram S3 explains how to wire an inverter to a premises
@anthonymwambazi7390 thank you, sir. very informative.
And how did you bypass the geyser
I didn't see a earth neutral bridge box. Is one needed for lux power inverters ? Awesome videos bro keep it up!😊
Not anymore
@@anthonymwambazi7390 do you know the brands of inverters that do require E.N Bridge box / E.N relays ?
I need help on that...i connected the input three core cable at the top of the main breaker, then output at the bottom .. With both of their neutral and ground connected to a bus bar...but after turning on the inverter fault light comes on...
Awesome videos Anthony - how do i contact you for a quote. I am in JHB South.
Are if you want to add solar panels do I remove generator?
no you do not have to they work together
Why is the input of the inverter on the changeover? Why not put the output of the inverter on the changeover?
i think both input and output are on the changeover switch incase there is a failure you will have to do it manually. incase the inbeter fails

How much do you charge for installation Anthony of similar setup?
hi there if its a back solution app 7k with panels about 9.5k to 12k based on assesment first prices are not the same
Hwst bru why did you have to use a 20amp as an output breaker from the inverter to feed a 40amp breaker ther
Hi there 20A is for inverter output to protect the inverter from overloading and 40A is for Eskom bypass if not using inverter backup purpose and cable rating size hope that explains well
I installed the same but used two am5 batteries
My question is how do I know if both batteries are working how does one see this in the settings
So with your connection.. when the eskom go off … need to come switch manually or its automatically
You leave it on auto provideded you select the loads you want to have without overloading the system
I know its not illegal however it should be on a earth leakage, but i dont see your Geyser on the earth leakage?
I have the same luxPower inverter but it does not want to pick up my battery (shoto) when we plucg it in. What can we do?
Hi please share a bit more detail what model number is the Shoto and the serial number of the Lux power on battery settings number 3 what brand type did you select and lastly what type of network cable are using as in pin configuration

Check the vid for battery settings
Hi Anthony, what is pin config for BMS 5kwh N Energy Lithium Battery with Growatt 5kw 5000ES..
Hi there N energy is a generic battery does not have a communication protocol yet as far as know it only manages it's self so you set it up as a lead acid
Thanks anthony
The SANS 101421 regs states that the geyser must be protected by an Earth leakage relay, I see from the video it isn't
just a couple of faults . incorrect CB installed in main DB that feeds the inverter DB should be of the same type as original cb's (cascading).
Blue is not neutral that must be taped up with black tape
Indicator lights with on protection must be installed to indicate what power source is present
Socket for generator seems to be female ,that must be male.
I would also use the same brand type CB for inverter return cb in main db this cb could also be an isolator type as the cb in inverter db already protects the cable and inverter
Noted
What am I doing wrong
You can't use a blue wire as a neutral according to sans rules and you can't cant have 2 pen earth's on 1 property and you not allowed to have 2 wires that is 4mm and thicker in a breaker.
Can you please type your website

Hello Anthony great video, where can I find your contact details
Only thing that I wish to know is Earthing.
So confusing
