You don't understand the level of bad luck I have experienced in the last couple of years so therefore I would not dare attempt to do anything myself despite the fact that I would love to DIY.
If it wasn't for bad luck I would not have any luck at all😢

Maybe all solar owners must switch off their systems for a couple of days and see what will happen? 🖕

And today it is back with a Stage 6 bang.....

If I had decent roof space at my house, I would go almost-off-grid:
council supply goes to a new small DB that has a plug for just in case next to it and the only other breaker is a battery charger that can be managed by data signal relay.    This council connection is 20A, so carries the smallest basic fee if any at all.    That gives you about 2kWdc charge capacity if ever needed.
entirely separate from council is the old DB running off battery inverter.    In effect the battery is pure isolation from grid.   It normally charges from solar input to battery inverter but if needed a relay allows the grid connected charger to also charge the battery.    All your house loads sit on this DB.
Because impossible to export, the NRS size limit on solar does no apply.
Obviously must still comply with electrical and building safety rules & regulations, but none of the other stuff.
Why not completely off-grid?    Most council bylaws allow them to charge you for there being a connection available, even if you don’t use it.   This way you get some benefit from the small connection - that 2kW charge can help a lot in bad solar times.
When I sell my house I will build a single floor home with the right roof to put up a LOT of solar.    My current house has awkward roofs and is too big for my 8kW of solar.

It will scream at you NO BATTERY and then drop the load, safer option would be to switch to grid to service the load while you work on the addition.
I saw that happen when they were installing my system, battery was shutdown...gave the on screen message is green NO BATTERY and then it dropped the load.
Probably also just safer to shutdown the system, do your changes and then start everything up again.

This happened to me about 2 years ago. One MC4 also melted like that. Turns out the cable was not crimped on properly.

The Guy Wire bases are 120 Degrees appart and 6 meters from the central base each Guy wire base is 1000 x 1000 x 800 and the central base is 1000 x 1000 x 410 mm 
One Guy base diagonal with the direction of swivel on the base this allowed us to assemble the turbine and tower on the ground. 
Total estimated 27 Mpa Concrete used was close to 3 Cubes in total all the rebar and steel mesh we had to supply the manufacturer supplied the base plate and threaded rod and the eyelet rods for the Guy bases.
More to follow...

There is the actual meter which measures your consumption, and, for pre-paid users, there is usually a separate CIU (customer interface unit) that just displays the credit balance and gives you a warning when you're running low. I have seen some cases where the CIU "talks" to the meter via a wireless link, but in most cases it "talks" over the wiring in the house. As I said, an inverter will break that connection and you will not be able to reload.

You don't have to intervene between grid and meter. You just need a socket that doesn't have an inverter between it and the meter.

Different brands of units behave differently. One brand that is common around where I live loses all it's settings if there is no power to it. Which means that when you run out, you first have to register it with the actual meter again. That registration is usually done via the key pad, so try to make sure to get a manual. 

Good afternoon all,
First of all @TaliaBis doing much better and is now in the general ward awaiting pathology tests that has been sent to Paris 'Laboratoire Cerba" operates on the French and international markets of specialized clinical pathology. The reason the physician had made the decision to seek specialized intervention is they can't find any traces of DVT( deep vein thrombosis) where the blood clots could have originated from and no injury or surgery that could have been the causes of the clots in the lungs.  According to @TaliaB brother they are not comfortable to discharge him until the results is known from the pathologist in France. He is taken off all oxygen and breathing freely and comfortable. He is still on blood thinning iv as a precaution measure. By the sounds of it he is now desperate to get back home to Cpt who can blame him.
Hopefully this will be my last update as i am sure he will be back on the forum soon then he can share more detailed information about the cause of the sudden blood clots.
Regards
Derek.

I use several. I usually choose supplier based on price.
Delivery time depends on origin. If the goods are coming from Chine, it takes about 3 weeks. If the supplier has a warehouse in Europe you can get items in 5-7 days.

If you mean can you easily convert a 48 V inverter into a 24 V inverter, the short answer is no.
You would need a different transformer turns ratio, dozens of different parts, different firmware, it's endless.

Two questions:
After an electric conversion, do they still leak oil? Get some pics from your friend fi he doesn't mind and share!

I was called out by a client in Cpt for a burning smell only at night in his main bedroom. As he explained it smells like something is burning. Indeed this is what i found. Old type Tungsten screw type bulbs in the headboard recess both sides of the bed. By the way these Tungsten filament bulbs is now officially discontinued and are not allowed to be sold in SA. Pictures below that could have had serious consequences for the house owner. As the pillows moves around when persons lying on the bed pressing against the bulbs that could have ignited the pillow. 




 
 

Some multi voltage smart chargers needs battery voltage to select either 12v or 24v. You need a charger or power supply that does not need voltage to switch the charger on. You can test the charger if there is voltage across the pos and neg clamps without a battery then you can use it on the external Esener battery terminals to charge/ wake it up. Then change the Growatt charge source priority to Utility and charge it to 100%soc.

I purchased the Pace RS232 USB to RJ11 cable from SolarAssistant, Loaded BMS Tools HS2.03 (Any PBMS Tools software works)
The ethernet cable used for master and slave is a normal straight-through network cable.

Try protocol 12

Thanks for this info. I purchased 2 cheap SunMagic 150Ah batteries to test out, and apparently, they are also manufactured by FiveStar.
Though the booklet that came with is exactly the same as the Felicity Solar battery, it actually has a Pace bms in.
After much battling using the Felicity BMS wiring, I wired up using the Pace, and voila.....all good.

Hi All

Just an update on the 25.6V 106ah S-Volt lfp battery. The setup of the battery was a bit confusing as my electrician did not understand why the manual stated incorrect charge voltage as my understanding was that it is a 8cell battery not a 7cell battery. After much deliberation between myself the electrician and the supplier we figured out the manual was incorrect and is indeed a 8 cell battery with recommended charge voltage of 28v. See attached data sheet that is still not correct. So to anyone purchasing the 24v S Volt battery it is 8 cell and chances are good that the recommended charge voltage is incorrect in the manual.
