@WannabeSolarSparkyhow much power do you generate on your best and worst day from the 10 panels? With regards to the sonoff. Does your geyser run on your essential side of the inverter and then you have set a time on the sonoff switch to allow power through once your batteries are charged. But if you don’t have enough solar power then the geyser will eat into your batteries supply? im asking because this is abit confusing. Do you have to monitor your solar production constantly in order to switch on your geyser? And your stove doesn’t run on solar at anytime regardless if you have enough solar power. I thought that your stove and everything would run on solar during the day and then when there isn’t enough solar it would draw from the power supply. basically I’m worried about eating into my batteries with the geyser if there isn’t enough solar. I can’t quite find the answers on exactly how the sunsynk inverter works. regardless I’ve already bought the 8kw inverter, will arrive next week due to stock. And at this point I’m leaning towards 4x pylontech us3000c but still haven’t made up my mind and I’m also struggling to figure out how many solar panels I need. I’ve been at this for weeks and all this information is mind blowing,

@WJB@P1000thank you for your response. Much appreciated

@WJPthank you for your input regarding the Hubble batteries, I just want to ask and possibly clarify a few things, First off I know that Hubble batteries are a 1C battery which doesn’t really bother me much as I will have multiple batteries but I’ve read that a 0.5c battery would have a longer life span, I have also seen the post regarding pylontech tech vs Hubble and how the Hubble batteries are of a better build quality, I have also seen more recent pictures of a pylontech batteries where as the build has improved internally. I have read that Hubble batteries are of a NMC chemistry and that the current market of lithium is moving away from NMC because the LiFePO4 batteries are better and give a longer life span than NMC batteries. my knowledge of batteries is very limited as I have only started my research a few weeks ago but if you have any more information regarding batteries and how to choose them it will be greatly appreciated I know that Hubble is made locally but to be honest I haven’t seen to many people suggesting why I shouldn’t get pylontech, Hubble seemed to be a problematic battery due to firmware issues which I do think may have been sorted out in the resent firmware update but I also don’t see people complaining to much about the pylontech batteries regardless if they locally made or about lack of after sales service. please understand that I’m not trying to bash Hubble because to be honest I know jack sh1t, I’m just trying to learn about the battery and why the people that bought them love them and the people that haven’t bought them don’t feel the need to have them and still suggest pylontech. edit: also I have followed the Australian battery testing and pylontech seemed to have done pretty well with an estimate of 4800 cycles and a SOH of 60%

@Scorp007@Mauritius B@18650@Chris Louwthank you all for your recommendations, I will go through all your links and see which one is best for my application. Much appreciated

Looking to get a single phase kw and watt hour meter. Something with memory. what I actually want to do is test my geyser for a day or a week to get an average usage. I’m playing around with my geyser timer to see what times suit me best an how much power I can actually save, also looking to test my fridge and my dishwasher. I’ve seen products for around R600 but I will gladly take recommendations on products some of you have tried and tested and is accurate. thanks

@P1000thanks you

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 😀

@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 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

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

This is what my whole house draws in amps and watts.. some people might find it interesting

@Nexussthank you for the information, look my end goal is to get off the grid completely, but to get the ball rolling I have decided to get the sunsynk 8kw and two 5.12kw 100ah batteries, (still figuring out which ones) I don’t just want to go buy a battery because so and so said it’s good, I’m trying to get the battery that is best for my application and because this is my first rodeo I’m very overwhelmed. At this point I will not be running more that 5kw at outages, i will however be purchasing panels in the near future to supply my geyser and charge my battery pack during the day, ( geyser is 15.3amps or 3700watts) regarding your above post I have attached another picture with specs on the sslb1, can this be correct because it says that it has a 1c rating on maximum discharge and the only difference with the pro max battery is its DOD of 100%, but then again I don’t see the sslb1 on sunsynk website, I only see the pro max battery. So I don’t know what to think.

Hi, so I am on the research path to find the right batteries to go with a sunsynk 8kw inverter. My supplier has sunsynk sslb1 5.12kw batteries in stock for the same price that I can get a pylon 4.8kw battery for. now for easy of use a lot of people have suggested the pylontech and Hubble but no one actually uses the sunsynk batteries. I’ve been reading up about the testing being done in Australia regarding the pylon batteries and to me with my limited knowledge looks pretty good. Only issue I have with pylon is that I don’t see the 4.8kw battery on there products list on their web page which leads me to believe that the 4.8kw that I can buy here in SA are discontinued and replaced with another model. Is this at all correct?? now I have noticed that sunsynk has two models of batteries, the 5.12kw sslb1 and the sunsynk 5.12kw pro max. The pro max seems to be a lithium ferro phosphate and the sslb1 is a lithium-ion phosphate. What are the differences between the two. I have uploaded the specs sheets and the pro max seems to be better although it is quite a bit more expensive. Is it worth it? the pro max picture has the lithium ferro written on the top of the picture

@Speedsterthanks for the info, I’m yet to start a new topic in inverters because I have so many questions about stuff like this

Unfortunately I’m also new to this so I can’t help you at all 😀

@isetechSo what you say is that I want to get an 8kw sunsynk inverter, the discharge rate is 190amps so then I would need to get 4 x 4.8kw pylon because it’s a 0.5c and it will allow me to discharge at 200amps to match the inverter Can you explain what you mean here? i also saw something somewhere which I obviously don’t understand but regarding the 8kw sunsynk inverter that 2 x 4.8kw is not enough because there is sometimes an error that occurs with low voltage. Does anyone know something about this?

@YellowTapemeasureperfect, thank you I understand now.

Hi @YellowTapemeasure if possible could you give a brief explanation what a 1c battery means and why it is a good thing. Struggling to info that I can understand. I might be getting a good deal on pylontech batteries but if they came outright and said it was a 1c I would buy them but I can’t find there c rating.. I did read somewhere that the us3000 was a 0.5 c but again I don’t know what that means.

Thank you @iceman

@YellowTapemeasure @hoohlocthank you for the information, these batteries will go to my brothers inverter when his lead acid bomb out. I have decided to go the whole way by spending the money and getting myself setup correctly to get off the grip. 👍🏼

Thank you for the information, much appreciated

Thank you

I won’t lie, I prefer yours to! Fair enough 😀 once again, thank you for all you help!

Awesome stuff, thank you. Thank you last question and then I will leave you alone 😂 why bsl battery? Any particular reason

Exactly what program did you use to create this, it’s fantastic, gives you everything you need to know all my n the same picture

Thank you Nexuss, awesome feedback!
