The fans are temperature load controlled intelligent cooling, not pure fixed on and off. Your older unit kicking in at 2 kW is normal for earlier firmware. Newer units have a higher threshold 3 kW, which is an improvement. On a cold day 20 °C at only 2.5 kW they ideally shouldn’t need to run hard if they do, it’s still more about internal component temps than ambient. Solis fans are generally quieter and better managed than other brands. So look at getting the firmware updated.

Yet Pylontech offers R2K eish man eish...

How on earth would the Power Forum a trusted free resource take responsibility for your batteries? Please send me what you are smoking seriously... 😎 The okes at Power Forum has always been solid maybe your Question should be focused on Pylontech....Besides Pylontech knowing the risk is attempting to engage with guys like you 🤣🤣🤣 a fortune 500 company engaging with the 44 left in SA but who am I 😛 I see it as refreshing and positive does Sunsynk do the same ? With 6 month plus warranty repairs? ....nope ..... It's a joke 🤣.... But the BMS should have Functioned at 275000 KM per second...just because you used a crappy budget inverter... seriously send me what you're on...

Swollen cells and then told “you overcharged them” while the BMS was supposed to stop it… ja, classic.Those older US3000s + Voltronic the real battery killers was a match made in hell. Weak balancing, voltage spikes the BMS couldn’t catch in time, and the logs still show every high-cell event. That’s why the trade-in is R2k and not “almost new” money.Used is used, boet. Depreciation doesn’t care about the brochure.

Spot on, @Yellow Measure . People get emotionally attached to what they paid years ago and the “status” of their big battery bank, but the market and the BMS logs don’t care about feelings. Once those cells have taken heat, imbalance or abuse, there’s no practical way to fix them. You can’t just swap a single cell like you replace a water pump on a bakkie the labour and matching alone make it a non starter. And let’s not forget a replacement BMS on these Pylontechs is sitting around R3k. So the moment one of these tired packs needs a new BMS which a lot of the low-value ones do, you’ve already burned more money than the whole battery is worth. That’s why the R2k trade-in isn’t “unfair” it’s just the real residual value after the logs have spoken. Keep running them till they die, or sell them privately if you can find a buyer who hasn’t done the maths.

Surely this is the same logic as buying a car. A brand new car loses a massive chunk of its value the moment it rolls off the showroom floor, and then continues to depreciate at a steady rate every year. Nobody walks into a dealership three, four or five years later and demands close to original purchase price just because it still drives or it only has 150 000 km. Exactly the same principle applies to lithium batteries and inverters, for that matter. A new Pylontech US3000D is currently sitting around R12 000 to R14 000, comes with 8 000+ cycles and a proper 10 year warranty. Yet people with 3–5 year old US2000, US3000 and US3000C packs that originally cost R20k+ are somehow shocked when a trade in offer comes in at a few thousand rand. Using Cycle count is only one data point to measure value. These batteries have lived through South African summers, possible high ambient temperatures, deep discharges, high C rates, and whatever else the installation threw at them. Health, remaining capacity, cell balance and thermal history matter far more than the number on the cycle counter. And here’s the part many owners forget the evaluation tool Pylontech uses doesn’t just look at the cycle count. It pulls the full historical life of the battery every stress event, temperature extreme, over discharge, high current event, cell imbalance, the lot. Even if the owner was completely clueless about what the battery actually went through, that data is sitting right there in the BMS logs for them to see. Once a product has been used, it is a used product. It has already taken the big depreciation hit and continues to lose value. Expecting anything close to new money for an old Pylontech is simply unrealistic. Keep running the old ones until they actually become a problem, or accept that the trade in value reflects today’s market reality not what you paid years ago. Or just sell them on in the open market and buy new ones.

Count me in I like free stuff!!! SUBSCRIBED again... Just in case...

Cool @TheMac , how much money have you invested to support the forum? These commercial companies are what keep Powerforum running who do you think pays to make this a free resource for everyone? How long does it take Sunsynk or any other brand to repair a faulty inverter? Short sighted take in my opinion… this is entertainment for some, but real support for others.

Power Forum Store is the cheapest on a JA Solar 550 Watt Panel @ R 2,257.45 Vat Incl https://powerforum-store.co.za/collections/featured-products/products/solar-panel-ja-solar-550w-mono-perc-half-cell-mbb-mc4

Yep I paralleled them didn't mess with the old firmware those batteries still work like a charm with 100% SOH the new ones not so sure going to do some capacity testes etc when time allows..

Nice!!

I have the 110 Ah AM-2 batteries too but also some of the newer AM-2 Batteries but their performance are not as good as the old ones they are also much lighter 42 KG for the old ones and 34 KG for the new ones.

Seems like I missed out on a great Discussion sofar many valid points mentioned sofar.. however the most important thing for me is what happens after the warranty is over will I still be able to have my Pylontech / Hubble /Blue Nova / Revov etc serviced repaired or refurbished?

Wow that does look very nice and neat

Please substantiate you comments with proof @Brani you are an installer and have hinted that on many occasions.. you are not an consumer and have many times indicated to us that you claimed to have vast knowledge when it comes to solar power and batteries .. however I will not further waste my time as it is not educational nor productive and I don't argue for the sake of Argument..

Lol Leshen has been a member longer than you have buddy almost as logical as your Pylontech argument.

Segen Solar does not sell directly to the Public do they ??
