@waynehooper Have you had a look at the Dyness Powerbrick Max yet?

I personally don't like it when a manufacturer, supplier or distributor comes onto these forums and post to tell us how great they or their product is and how much they care (biggest lie ever). If they post something like the above then they must be willing to respond to questions being asked on the specific post. They treat it as their own personal advertising board without taking the responsibility. I believe if they post here then the admins of these forums must enforce responsibility rules and remove their "advertisement" posts if they don't respond. I am in the process of upgrading my system to a bigger inverter and battery and I am in the research phase. I remember how Sunsynk ( @Keith Gough @David Drake ) treated their customers and that will affect my decision. I am watching the other guys as well. I see some activity from Solis on the forums lately so why haven't you responded on this post yet, @Solis Inverters SA ?

Years back I had contact with what I believe to be a legit supplier of them in South Africa and their normal price is quite expensive, much more that what the fake ones are being sold for here. Unfortunately I cannot remember who the supplier was. You can assume it to be fake when the price is good.

All the best to @TaliaB . May God provide you strength and a speedy recovery.

Good day I have a Sunsynk 5k and a Greenrich 5k (UP5000) installed in a house I am renting. I purchased them in January 2023 and installed them a few weeks later. There are no solar panels and the system is purely a UPS system. How do I determine a value for them in order for the landlord to buy the system from me so it can stay in the property? The price for them at that time was around R52k. Nowadays you can get the pair for around R29k if on special. Thank you

@TaliaB @Scorp007 I had a look at the 5A and it is good for my budget. Thank you for the advice.

I was looking at this table from their datasheet and was wondering about what you said. Should I rather stick to the provided table specs or can I safely buy a larger charger (in amps) to charge my 20ah LiFePo4 battery even though for instance the 25A specs recommend minimum 80ah?

May I assume you used it before? I saw reviews of people complaining about the Bluetooth connectivity and app. Is that the case?

Good day I would like to charge a 12v 20ah LiFePo4 battery and is looking for an appropriate charger. Do you have any suggestions on a specific charger I should consider and perhaps where to buy it? How are the Victron Blue IP65 chargers? I read that they need to be charged at around 14v+. Is that correct? I believe that the Amp/Hour rating of the battery determines the charger rating. For example a 5 to 7A charger will be fine for this battery but a 20A charger will not work correctly. Am I correct?

It did not favour a specific time. Night or day. (I don't have panels on. It is just a UPS) Just the other day it happened during the day and I was close to it and tried to see something on the Sunsynk. I saw the following (not my photo) for a few seconds only while the battery seemed to be starting up. So obviously the inverter cannot communicate with the battery during that time. The biggest question would be whether the inverter is causing this "re-start" or is it the battery that is just restarting. As I was typing this I was wondering if I should consider replacing the comms cable between the battery and inverter.

Does this sound carry through to your recording studio?

Long ago there was an advert for either Band-Aid or Elastoplast with a kid removing his plaster and asking "Where my cut go?". I suspect they will be asking "Where my electricity go?"

I assume this would mean France and Morocco had to be synchronized in frequency. If so, how? Is France and Morocco connected by themselves? Or it this more a case of France helping one side of Spain to get up and then Morocco another side and once up they could synchronize the two sides in Spain after disconnecting from France and/or Morocco?

There are so many fascinating lessons to be learned here just from an educational perspective alone. I just hope the real reason for their blackout comes to the fore. A national grid is such a delicate system and the cascading affects caused by a bad player, be it weather or failing equipment or mismanagement can be a wonderful teacher... if the student is willing to listen of course. I am keeping an eye on this news event with childlike excitement to learn as much as I can. Its not everyday that such a major grid event happens. In a traditional system where you have large generating units (coal, nuclear) you have the ability to absorb frequency fluctutations caused by a large load increase/decrease and adjust accordingly. It works with the assumption that you have enough of those large units to do that. I just wonder; if you remove those and you have all these smaller generating units (so-called green) then how is that achieved.

Indeed. And the way you use it conforms nicely to my earlier point.... You already know what to look for and you are able to pick up on any errors or false statements of the AI. You use it to save you some time but not to solve your issues or ignorance for you. I bet you always go over what the AI gave you just to make sure its correct.

Its seems the honourable @haudevbe has been kicked. Good job.

😁 A disclaimer is not necessary if you don't use AI to answer questions 😉 Anyways.... AI generated content seems obviously to be out-of-place amongst normal conversation so I think everyone will already know you used it. As long as you add a little genuine Welkom charm in there as well. 😄

I am part of a programmer online discussion forum and this trend has been discussed at length on there. It basically comes down to this; The people who can afford to use AI usually don't and those that cannot afford to, do. The uninformed are usually quick to run to AI, unaware that there are many false statements coming from it. They will never learn the real facts. I have been in the computer world far too long to fall for this fad. I treasure experience and great insight coming from an "ou ballie" more. 😄 Fortunately there are many greatly experienced guys on this forum that have already proven their chops. They are well known by us that frequent this forum. I hope such user accounts get removed.

[bump] Does anyone have an idea? [ping @Bruce Gu ]

I have a 5K Sunsynk and Greenrich U-P5000 battery as a UPS setup. Sometimes, rarely and inconsistently (Maybe once in 3 months or longer) I will hear a few beeps coming from the setup which stops and when I reach it I see the battery "restarting". Restarting being the lights acting the same as if I just switched on the battery. I do not know if the beeping comes from the inverter or battery. This happens only once at that specific moment and not again until some months later. There are no indications of errors on the Sunsynk screen. The SOH is 100%. I do not have montitoring software connected to it or even the Sunsynk dongle. The Greenrich manual does not seem to indicate anything. The setup is located in a well ventilated area and a few nights back it happened during cool weather. The setup runs smooth during loadshedding and power cuts and charges normally. I have had this setup for 2 years now. I cannot remember exactly when this started but I have a fading recollection of it being about a year back. Electricty in our area is not always the smoothest. Does anybody have an idea what the cause may be?

Excellent, Nicely spotted. Thank you.

There are many posts online about the NAD protection mode and how many times faulty or even sub-par components had to be replaced. I wonder if your device has a similar issue with sub-par components on their way out.

Hello @Energy-Jason Firstly, thank you for this wonderful forum that has lead to such great discussions. I am part of another online forum that uses the same forum platform software. On their Home page there is a link "Unread Content" right at the top which stays there. It is very helpful for me as I go to Unread all the time. I know PowerForum has such a link from one of the dropdowns at the top and also right at the bottom but I was wondering if you would be able to add the one at the top as a constant link as shown in the below image. Thank you

I second this. It will narrow the search.
