The Megawatt-Hour-Per-Month Club? Yes please! All-time-high was last month (October) at just under 1.3MWh though the average is around 1MWh p/m even in winter.
System (details in signature) payback time will be under 4 years. Now (whilst load-shedding is on standby and prices are black-friday-good) is the time to upgrade: if your're on the fence, pull that trigger! Will add some more batteries on my own system with the profits once it's all paid for itself 3 years from now.
 

Almost good enough cup grounding more efficient answer for your friend.

My suggestion on solar panel replacement would be 4 x Ja 550w or if you have space 5 x JA 550w 5S1P the latter will work great providing ~210v Vmp @ 13A. Below data sheet of the JA panel range you can consider. I have use these panels in my installations and they work great with the 5kw Sunsynk.
JA-Solar-525W-550W.pdf

Where are you situated(province). Is your solar panels partially shaded? Even at 07h30 you have very little current flowing. Your voltage is between Voc and Vmp due to almost no current flowing. Below an example on SA from one of my clients in Gauteng this morning that consists of a 3kw Growatt inverter with 2 x 460w panels in series. If the panels are not shaded you have a problem with the solar string connection. The Trina Verso panels are not suitable for the Sunsynk 5kw inverter due to the ISC of these panels as previously mentioned by @GreenFields,but that should not affect the performance though, the Sunsynk will clip the current and only use what is safe for the inverter. The ISC for the Sunsynk is 17A and could affect the warranty as this is a hard limit specified by the oem. 

Try this: On the inverter's screen, find the Status Page, and then give the values for Volts in the blocks for Solar Power 1 & 2.
My guess is it's around 125Volts, give or take a bit, when the sun is shining.

If @GreenFields is correct about your panels you may likely need 550W canadian solar or ja solar as alternative, they have a higher VOC rating and lower short circuit current rating AFAIK. You need to get the exact panel information from your installer so we can advise you properly.

The Growatt 5000ES has a total charge capability of 100A solar+utility. To determine the best charging setup the question would be out of your 400ah lfp battery bank how far(Soc) do you discharge your battery during non solar periods( at night). Depending on your answer the best charge current could be calculated. As best practice always endeavor to charge the battery at lowest charge rate possible 0.1c ~ 0.25c. What is your battery module spesification 0.5c, 1c. 
Also what is your generator spesification in VA? Generators have a power factor of between 0.75~0.8va this needs to be taken into account when setting charge current as your generator will have to delivered charge + loads connected. Is it a petrol or diesel generator? The utility charge current is set in program 11.

No, solar inverters don't heat up your house, but they can generate heat as they convert DC power from solar panels to AC power for your home. Solar inverters dissipate this heat through fans or heat sinks, and it's added to the ambient temperature of the inverter's enclosure.
On the other hand the fan noise cooling the inverter might be a nuisance depending on type of inverter but like you say you don't have other options for installation location most probable due to db board location.

Yes you do i would suggest the double pole Tuya 63A smart mcb as this one has a ka rating of 6kA.

There could be various reasons for the failure and damage in your picture but the most common hazard on solar arrays is ARC FLASH. 
The types of Arc Flash that can be generated within the solar industry are another major risk. With arcs capable of reaching more than 3000 degrees Celsius in temperature, these arcs not only cause fires but can also melt materials such as glass and metals including copper and aluminium. This can subsequently ignite any combustible materials and items in the surrounding area. In the solar industry, it is not only the direct risks of arc flash that must be considered but also the many possible indirect risks, too.
Improper crimping of MC4 connectors, loose connection in combiners, damaged solar cables ,damaged solar panels(micro cracks) can all lead to arc flash. Great care need to be taken when installing solar panels as dc is not as forgiving as ac curcuits.

2 years is quite a long time for storing lfp batteries. You need to keep an eye on the soc as they have a 2% self discharge. Charge them to 80%soc every 3 to 6 months. Store in a cool dry place out of direct sunlight. 
Just as a matter of curiosity why don't you sell these 2 battery modules or is there a specific reason you want to keep them in storage. 

@Kory Below link how the process should be done. In the document their is a section "How to" download that pdf and follow the step by step explanation.
Your installer should have applied first and after getting the permission letter he should only then have done the installation. But it is done so just follow the process. You will need a test form accompanying the coc.

Below test certificate that needs to accompany your coc. If you don't have a test report you need to get one from the IE or MIE that issued the coc.
 

 
 

Eskom’s new plan to punish solar users

According to the voltage graph above the panels can't be connected 9S1P( 9 series) otherwise you would have seen ~400v. According to the voltage and current graphs you only producing max 2kwp. I would suggest you contact the installer to rectify the pannel connections, same panel count on both orientations. 5 panels North 5 panels West paralleled at the combiner that should give you ~ 5kwp.
 

Mixing different panels, whether connected in series or in parallel, ALWAYS reduces the installed wattage.
Different solar panels reduce the effectiveness of the controller to track this optimal power point. Is it a problem to source the same panel as already installed. Give us the make and model( picture of nameplate on panel) of existing panels if you battle to get the identical panel maybe we could assist.
 

To appear incompetent and to actually be incompetent are two very different situations. The perceived "incompetence" is often a carefully planned strategy to keep the coffers full, allowing for even more people to dip into the funds.
A good example is the pension fund 2 pot system who is gaining the most not the poor working class trying to survive no the tax man is helping to keep the coffers filled up. A crying shame.

Good afternoon forum members,
Update regarding @TaliaBprogress in hospital. I spoke to his wife this morning and was given permission to post what happened his symptoms and his progress. He suffered a pulmonary embolism and had difficultity breathing. He was placed under sedation for the past 2 days and is currently receiving high flow oxygen therapy and was placed on an Streptokinase drip to dissolve the blood clots in his lungs. He is still in high care unit and not out of the woods just yet but doctors are positive of a full recovery after blood clots are dissolved and clears. 
Derek.

Good evening forum members.
I just got word from @TaliaBbrother that he has been in Mauritius for the last 3 weeks for work/ vacation and has taken ill this afternoon with serious breathing problems and was admitted to C Care Wellkin hospital in Moka Mauritius Apparently he is in high care unit awaiting test from pulmonologist. I will keep the forum updated and pray 🙏 that he will be ok.
Thank you Derek.

I have learnt a few things from this video i didn't know not to wind the wire tight with a pair of pliers before inserting and crimping the wire. Great video thanks.
I know most electricians go bos with a pair of pliers and Gp wire ends before connecting to db breakers🤣 I am waiting for a lashing from the electricians including @TaliaB🤣🤣 Just joking guys.

While we are on MC4 training here😝 take a look at the video from Greenwood solutions trainer Veli for some very good pointers.
 

It is very important to use this dedicated mc4 crimper below.

I agree with @Virwatyou didn't really find the problem and still might have a loose connection within one of the mc4 connectors. It is now difficult to actually visually inspect each crimp once the mc4 connector contacts is pushed into the housing. There is a method to check for loose connections but you need to do it with caution. You will need a 20~30 amp dc fuse or 20~30 amp dc breaker to do this test. 
1. Switch the Victron mppt off in the settings page under battery 
2. Disconnect the pos and neg solar input wires from the Scc be cautious they don't touch together. 
3. Ensure the fuse holder is in the open position and remove the fuse. Connect pos and neg to the fuse holder pos top neg bottom or vica versa doesn't really matter. Make sure they are thoroughly tightened.
4. Insert the fuse and close the fuse holder (quick action). If you do have a dc clamp meter you should read just below 12 amps(Isc). Do not use a multimeter on amp scale as the max for multimeters is normally 10 amps.
5. Leave it for around 30 minutes in the shorted out state then climb onto the roof and check all the mc4 connectors for arching or hot to the touch. If all checks out ok it might have been a male and female connector not pushed in all the way( you should hear a distinctive " click" when they seat together. If all is ok after 1 hour with panels in full sun at noon you should be ok. Discconect and assemble the process in reverse. Remember to open the fuse with a quick action the last thing you need is arching across the fuse terminals.
DC is unforgiving if there is loose connections that is how your house 🔥 burn down.

Well done @ClintonDBNand @TaliaBthat is what this forum is all about assisting each other to solve íssues one by one.👏

Talia, thanks so much for your assistance. I disconnected and tested each panel. They all looked fine, which concerned me as I felt I had my resolved the issue. However, it did resolve it! My assumption is that it was indeed one of the connections and by disconnecting, testing and reconnecting, I resolved it.
