Consider the loads  you draw that you will ever need 9000W concurrently from your battery i.e mostly at loadshedding time

@FixAMessI plan to go off grid eventually, but for now it will be 8kw sunsynk and 10kw batteries. Solar will come shortly after everything is set and running

In short, if you're the average guy, just go the toyota route and buy Sunsunk and Pylontechs...Simple, combination works, very reliable, well supported and there's plenty of forum support.

I think that because of this quote I’ll be going pylontech. I’ve been doing a lot of research and reading all the threads in the batteries forum and at this point the price is good, the longevity seems good if you look after the battery and stick to the guidelines, most importantly the batteries communicate with the inverter well. So honestly it’s a no brainer.. and I’m a Toyota gun 😉

I’m not sure if I should go for 3 us3000c or 2 up5000. What I’ve read is that the us3000c gives a 7 year warranty and if I register the batteries the warranty is 10years. The up5000 is only 5 years. 
 

I would like to go for the us3000c because if a battery has a problem I can send it in and still have decent capacity so I won’t feel it as much, the problem is the price! It’s basically R10000 more expensive to get 20ah more… is it worth it? (2 up5000=200ah and 3 up3000c=220ah) 

do you have and thoughts on the above. Advise would be appreciated

I have found that people get lost in the figures, KVA,  kwh ratings, electricity account figures, etc and loose  focus on the important stuff. 

The important stuff being the part that you understand your load requirements and time of use.

If your electricity account is R10k and you install your whole roof full of panels and a small inverter with a battery suitable for the inverter, you going to be pretty screwed if you entertain in the evening and run heaters, a sauna/ jacuzzi or aircons etc, or have tons of security lights around the property, etc.

Like the C rating and cycles of your battery, if you only use a small percentage of the total power of the inverter, because you want a long backup for your security system, then a 0.5C battery could be ideal which will also reduce the DOD adding years to your batteries, if you understand what it is you looking for, choosing the right equipment is simple. 

My point - focus more on the important stuff, then design a system around it. It's trying to find a person or company to take the time to understand  your specific requirements and create long term solution becomes the biggest challenge.

This industry has become a means to a quick buck for many due to the lack of understanding, I find it rather amusing when customers request I sit in on meeting with installers. "baffling people with bullshyte" comes to mind  

 

Thank you @isetech I really appreciate your input. At this point I have decided to plan my house for essentials and non essentials. I am making progress and getting ready to drop the hammer as soon as I’ve made up my mind on the batteries. And find good deals 😀

@P1000Are there any other reasons why you would go for bluenova 

Sure, they have good local support and very good charge/discharge rates and very good warranties.

@P1000thanks you

 

Great choice.

That is because they are basically white-labelled pylontech batteries.

Many seem to have, we know that Hubble has had some claims (and that they were honored). 

If price were no objective (as your thread title suggests) then there is currently no better that the Zenaj Aeon LTO battery. You will probably need 2 or 3 of them, but they boast a 22,000 Cycle life at 1C discharge rate capacity. I am not sure of your age, but that's probably more than your lifetime. 😄

They are pricey though, and realistically, considering South Africa's price-sensitive market and weak currency, so you have a choice of Freedom Won, Pylontech, Hubble, Dyness, BYD and BSLBatt (and some others that I haven't mentioned).

I have both Hubble and Pylontech at two different installs, and if I did another install today, I'd probably go for Hubble again. My reasons are many, but a 1C battery being locally supported with a good track record speaks volumes. I'd also consider BSLBatt (another 1C contender) and BYD, depending on price performance.

As all of the available batteries are pretty much new, testing of 10 year warranties isn't possible today. The closest you will get is the testing conducted in Australia https://batterytestcentre.com.au/   

I am looking for Battery options to move to solar backup for my energy needs. I am sitting withQuotes from two different vendors talking about Voltastage 1 (5.12KWh) and Sunsynk. 

Can you advise which is the better one between the two OR whether I should even be considering them
