Also still learning, Sunsynk 8kw with bulls. I have my setting like this. As I experiment and learn, I am hoping to get @Leshen on site to help with the Earth Bonding, and would have asked, But as we are on a same journey as you and I was to afraid to ask what you have now asked .......... I am controlling my battery output like this. I seem to be to only one doing this. I also have the max sell to 40w. seem to remember this has a influence on back to the meter?? But not sure. Setting those to less watts as I have done means the battery never exeeds over the wattage. Why? well I should have installed 50mm for battery cable but at the time only did 35mm. Then I discovered that the battery will exceed the drawn amps on the cable. Yes I can change the cables, but lets learn first. This steps it down gradually nicely .....

I am also keen to learn on this issue as I have two 6 x 450w strings that are similar and one always is different to the other in watts, amps etc and hope to learn from your issue. Maybe post a picture on your panels and what you see??? The visual may help

I replaced all my 7AH with the 8AH from take a lot at around R550 a battery long before inverter purchase. Thats Electric fence (Exactly the same as yours), centurion swing gate motor and the alarm which was a big problem when on 4 hours load shedding the gate and alarm stop working. problem solved. Have not replaced a battery since. Your gate / garage doors dont work without a battery. Lucky the fence does with out battery but has to have AC all the time. I have not replaced any battery yet, definitely more than two years. https://www.takealot.com/12v-8ah-battery-lead-acid-gel/PLID59533565

I can certainly comment on the Inverter Sunsynk / Deye etc. Brilliant choice. We have ours working with a basic install about 10 days now. I setup the solarman app and its telling me I am 95 percent utilizing my own generated power. I have a smaller UPS Essential load like you, House plugs, But that said its Dishwasher (day use on PV only, not battery at night). fridge washing machine. But the amazing part is how it back feeds into the non essential using PV and Battery. geyser, pool - Borehole pump in the day from solar after a full battery. The nighttime I am still learning. I have the BLSB (Bulls) battery.

Thanks, I was wondering what it was and my other mentor >>>> Google came up with that 😀 , I would check on this forum if anyone has experience with these. I learned how important a battery is to your installation also being quite new but growing by the day and by reading on this forum. My thoughts are you have a 5 kw Deye and this battery seems to compliment that 5kw. what are your other choices?

Love this choice ..... Best choice I think

You need Eskom and you will have cold water at night time load Shedding, or use up battery to heat water at 2am. You will never have cold water and never be reliant on Eskom. The 48kg are huge, even 19kg lasts long, Have spare like I do and when one is empty I change to the other and have at three months to fill the spare.

I built my home made battery charger to help my people that work at my house. I gave them each a 7AH battery and a china mall R35 LED light. I also gave them a LPG gas single cooker with bottle.Bring back the battery and I give you a charged one. I bought a number of these batteries and solar charge them. The cost was around R240 and R35. Its changed their life. No more paraffin.Good light for at least a week or two. Now imagine Eskom had a few of these power points. You bring me a 7AH and I give you a charged one for say R5.00. And I charge it with solar. You will change the life of 10 Million people, Instead they squandered Billions on cars, houses, overseas holidays etc etc. R275 to change a persons life???

@Deez I was thinking about this topic. My geysers are covered by Home Loan insurance. Lets say they are not, and I have made no PV investment to heat the water. What are my options >> new Geyser. Yes but then a 150l > How do I heat it?? EV tubes. No thanks and pretty costly. PV Maybe but also costly ?? >>>best hot water ?? GAS?? Yes please. Yes yes. No Eskom, no power, far less dependency. The difference it made in our lives taking out the electric hob and Oven and putting in the Gas was Huge. Our gas usage is 19KG about every 4 - 5 months at R500 a cylinder refill. Endless no worries every during every load shedding. Even hot water for coffee on a whistle kettle. imagine a geyser that works on very little gas to heat water when required. Bye bye eskom completely

@phalaborwa This has been a most interesting chat topic. Who would have known. Thank you for your input. Down the line this will be used for some advise and use. If there is a passion it spills over and solar is out passion.

I would not be discourage from using any 2 KW, however the Geysewise has some positives on the PTC element. Either way dont be discouraged using a smaller KW element. I agree with Vassen. it will take longer to heat ,use less power but longer.

@Deez the PV system has a dual element 900w DC and 1500w / 900w recommended for 150l and 2000w AC /900w DC for the 200l. The 900w heats the water via DC (PV) to a special MPPT controller to the PTC element. Yes it heats it. Even at 900w(200l). The day would start at 55C, then the morning people shower/ bath 26C - 30C. At the time I use the water 55C around midday, I am old school and shower quick, now at about 44C, come 3pm to 5pm back at 55C again. I also have the 150L , works even better as its smaller at 900w naturally. This is winter

@Vassen @Deez Exactly. I have three years experience on these. Geyserwise dont use a element in the element if you buy from them. This is the splab on them. Its a bakelite material I believe that does the heating An immersion heater element that offers inherent safety and improved functionality over typical resistance-wire heaters. Our new technology utilises Positive Temperature Co-efficient (PTC) chips as the heat source. You can even buy this for any geyser without all the PV stuff https://www.geyserwise.com/products/elements/2200-w-ptc-ac-element/ So that would not hold true at all about a 2 KW. I always see the geyser as a large kettle. Would a smaller element in a kettle have a big difference. Say you put a 1800w in a 2500w after it broke??

@Leshen I see you are often doing updates to the Sunsynk. Would it be possible to share with us how that is achieved? Who does the update and how is the serial number found? Thank you for all your wise help and time

My thoughts when I read this. I have a torch. I used it until there was only a faint light, It has four batteries in parallel, I open and only change two. Torch is working great after only changing two of the four. The other two are old and not the same voltage/ amp anymore. Should not be a problem? Lots of conflicting information. Did you pay R4000.00 for two 200w or was there other things? Do you have a china mall. I made a small battery solar charger a few years back with a 100w panal and a PVM charge controller to charge a 7AH(gate , security etc battery). I think the whole lot set me back under R800.00. Something like this. https://www.takealot.com/all?_sb=1&_r=1&_si=059e7f3422a6404cd83dffe1afcb9847&qsearch=Solar Charge Controller
