The Onkyo SR-606 rev-04 schematic shows voltage selection.

Insurers will of course take control of this emerging hazard, they move quickly when something new tips the balance sheet. Personally I will sit on the fence and watch the EV gold rush develop, lots more entertainment to come that's for sure.

Fact.

Let me guess, he talks rubbish because your extensive experience and knowledge of Africa does not align with his opinion. Please enlighten us, the topic is - AFRICA -Have you? Would you?

An introvert who went from a well paid teaching job in Japan to the Jungles of Africa. The demise and subsequent odd behaviour began with rejection of the Japanese work ethic and a series of videos aimed at crushing the dreams of anyone wishing to live and work in Japan. All of his original video content has disappeared.

This guy appeared at my sister-in-laws rent rooms over in Banglamung Nong Prue M1 a few years back. He was living in Japan at the time and looking for a new adventure in Thailand. A lot of reasons to hate Africa https://www.youtube.com/watch?v=sbTtvZVxMHY

Which I would expect our so called DIY & Electrical Forum Expert to fully understand and not belittle people with jelly bean nonsense.

I forgot to knock off nothing. Does not matter how much jelly bean nonsense you apply, my answer and the diagrams result are correct. There is a reason why the diagram shows 33V at the output and its not a mistake. Educate yourself and all will be revealed. PS Its possible the widely used diagram was taken from here https://rayshobby.net/wordpress/24vac-to-5vdc-conversion A little more help understanding half wave rectification with and without filter. https://www.youtube.com/watch?v=N7EUf1GAQuI

The output voltage of 33V given in your diagram is correct (approx) for half wave rectification with filter and no load.

Yes and its a good idea to start the BMS and new cell pack life with a clean slate. Balancing packs of large cells can take some time though.

Not everyone is nervous, for some; DIY solar is a hobby and take ROI far less seriously. I on the other hand closely monitor the returns from solar systems parked on packaging sheds owned by my Thai family. It is of course wrong to claim solar is powering your home at no cost before payback is achieved. Towards the end of the day when work consumption drops off, our electric lift truck grabs a tiny amount of solar power but I never claim its surplus and free from cost.

Who supplied this inverter?

That is just crazy and you really should take this to Sofar before attempting any more firmware changes. It is possible they have several versions which changed in production over time. They should know what version you have from the serial number. You should send this to Sofar and ask why it differs

I posted a photo of the manual to see if you have the exact match. They do not use any apps. Data is collected from the inverter and separate energy meter manually. My brother-in-law commissioned the inverter, he is very thorough when checking to see if the street meter shows any negative metering. The owner prefers not to give PEA any net metering evidence and always checks his meter after switching to no export. In the correct manual pins 15 and 16 are CT, pins 5 and 6 are the meter RS485 which is an alternative to using a CT. It would be interesting to see how the table in your manual differs from the table below. Anyway, to avoid complicating the issue with more checks I will leave you in the hands of Sofar.

Small update. User of same model inverter as yours reports zero export when anti reflux is enabled and its power set to zero (2kw strings set independent). He checks this by viewing the street meter and a bi-direction energy meter on the main feed when solar production is greater than house consumption. His display reads Reflux Enable when anti reflux is enabled and goes back to Normal if the CT is disconnected or reversed. There are many variations of firmware inside these inverters often based on the country they were intended for. Having the incorrect manual in the box and the inability to change country code is a red flag. I hope Sofar have not got crossed wires over your inverter type and sent the wrong firmware. The proper factory included manual for this range of inverters is shown below.

Google results can make you crazy - look at this one for 18AWG https://portablepowerguides.com/how-many-amps-can-18-gauge-wire-handle/

You are likely not missing anything and picked up a result that has taken length into consideration. .5 or .75 multi strand cable will suffice for the short length you require. Most PC power connectors have the shared ground (black) doubled up.

There are EV's on the road which are 5-6 years old have clocked 160,000+ kilometres and are still reporting 100% state of health at the battery. Can all manufacturers achieve this result, we have to wait and see.

True and the setting to no export should result in a tiny import of about 10W. The inverter trends on the import side to avoid the meter creeping backwards.

One more question just to be sure I am on the right page. Is this correct? Before the firmware update you could always stop export completely and the meter would not turn backwards when solar production exceeded house consumption.

I have got to be careful what I say here because there are so many firmware variants often country specific. If you are sure the CT wired correctly and you have done a complete restart after enabling reflux then best keep to your plan and contact Sofar again

Is the meter creeping backwards while in this condition?

If CT is wired correctly + anti reflux is enabled + CT mode selected + power set at zero :- The inverter should be derating with no export. Depending on firmware version, the display should say Reflux Derating on the top line and power in watts on the line below Is you goal to prevent any export?

Copy the folder to the flash drive. You will then have a folder on the flash drive named firmware which will contain all of the update files.
