Place your work up on GitHub if you don't mind - im happy to contribute to the project.

Removed the tracker, could not locate any obvious caps or transistors that looked bad (did not perform any test, just a visual check) could not remove the heatsink to inspect those 8x transistors (4x + 4x -), tried to remove the screws but the heatsink would not budge & appears suspended by the transistors , did not want to force it off.

Hello, My kings tracker popped a transistor here in Cape Town after the last cold front by over volt cloud effect 😞 I used to run 3S 2P 415w Canadians for +- 1.3 years & recently added another 3S-1P JA 455w with a slightly higher volts rating (Feb 2022).. Looks like on the 05/04 at ~11:30 there was a spike where after the mppt was not happy anymore 😞 Symptoms are: relay connects, volt drops to battery volt @ 51v and then relay disconnects and tracker displays the open circuit volt. Rinse & repeat. So im guessing a transistor failed & was wondering if someone had a broken king with a working tracker I could perhaps buy as spares ? Its still generating energy but not even 50% of the 9 panels at the minute and the constant disconnects well, its not very useful at the minute at all 🙂 Yes I have done the full off for a while without any sources, still the same. I have opened the inverter case and briefly inspected the tracker, I saw no popped cap or circuit blown. The inverter will be going off to the distributors for a repair quote but in the meanwhile I'm trying my luck here to maybe locate a replacement myself and attempt a self repair. Will be stripping the inverter a little more this afternoon in order to check if I can see a blown transistor.

yes they are all showing up as entities but not as "native energy" entities that can be used in that energy dash but that was no fuss to convert power to energy and use it in the energy dash, converted the "amps in|out" to watts - > kw & then finally energy readings too to get the battery stats to work. I had to convert some of the whatts values to kw first (creates new kw entities) and then feed these converted values to the power integration that produces proper energy values that were required for the energy dash. and then I played with the utility plugin to create by own "energy dash" (this was before hass released their) - I don't look at this as much anymore but kept it as a aesthetic to show to people.

Hello, did you ever get this issue resolved or sold yours for sunsync ? recall accepting this after having the 69 error that dropped the PV & updated the firmware & just accepted this as "better as the previous issue" - revisiting a year later to check if this was maybe resolved in some later firmware ?

Thanks for the honest reply, same here hobbyist DIYer 🙂

yep agreed, it sucks getting that little kid feeling when battery shopping and finding deals that looks to good to be true. Mind you I feel sorry for people who just order & don't do any due diligence. A question for you @WannabeSolarSparky if you don't mind, if I take the one part of your forum nickname 🙂 you don't happen to assist random DIY folks with CoC`s ?

Hi All, Has anyone purchased anything here before ? - Looks like they are based in Bloemfontein. Just curious because I’m after this battery & they are selling for +- 3K less + free shipping vs any of the other online e-tailor Their domain was registered: 3e. creationdate : 2021/08/30 09:49:32 Did mail them just now asking of they are real but in the current day & age we are living + the stories that you see going around my thoughts with new domains popping up just before x-mas with prices that "looks to good" smells a little funny I.MO. Thanks Konrad

Hi @R3plic8, This is interesting I never knew of this esphome integration & im a hass + esphome user!! Question: Have you had a play with this and collected metrics to hass & are able to change your input/output sources on the inverter ? Im using this at the moment and it is working very well, just curious on this plugins polling cycle for data collection, ive gotten this integration down to about 10 second refresh but sometimes only see inbound data every 15/20/30 seconds so its not perfect but ive been managing my system for over a year using this method. Curious if this is any better? (I have a esp32 & nodemcu here in a box waiting lol...)

hello @Solar Assistant - Care to share a little more detail on this? I can only assume that the Pi as a docker host with influx, grafana, your custom site, MQTT in there too perhaps ?

I have not tried them but the supplier confirmed that they are just rebranded pylons and works fine with regular pylons (just the name on the box that are replaced, battery sacks and hardware comes from pylontech) Dealership prices are 13999 ex vat at the minute for the 3000c, No shipping.

Actualice su firmware Kings al firmware más reciente: 71.94 y los 69 problemas que tiene donde se producen las desconexiones de energía fotovoltaica o ca desaparecerán. Encuentre el firmware en esta sección de descarga de foros.

Manufacturers state 6000 cycles at 80% DoC at 25 degrees, so you should be good going from 100% to 20% SoC every day in terms of reaching 6000 cycles. I run my inverter in SBU mode with solar only for the battery charge source. (Sunny days) Im a low energy user (15 kWh a day on average / no AC running! ) so my small array carries the base load during the day & charges the battery and the 4.7 kwh usable part of the battery carries the night load until sunrise. Depending on how intense the dinner making routine is of course, I sometimes hit 20% SoC about an hour before sunrise where the inverter is set back to grid assist (SUB) & then between 08 am and 10am back to SBU mode. 50 to 80% in your case is very limiting in terms of what a LifePo can serve up, you missing out on 50% & only using 30% of available energy. Its a LifePo not a led acid 🙂

I came here to ask exactly this! Thinking by myself last night "who else here recently build a small PV system to combat load-shedding & the ever rising cost of corruption are now moving towards plans to extending their system further." With the likes of City of Cape Town, DA & others pushing really hard to be able to purchase from IPP`s, I foresee Eskom heading towards a slow death spiral. Unfortunately, this will be a the cost of the tax payers. It only logically makes sense to push harder for going off-grid now, shame that the brainless government is digging a hole even deeper for themselves & the entire country.

Hi @Coulomb, I have added a US3000c to my setup recently just before the x-mas break. With the 3000c as the master the weird dump & charge fluctuation seen from the start of this thread with just the one 2000b battery has gone away. Im guessing the firmware / settings has improved a little on the newer model battery vs the 2000b
