I want to connect Rasbery Pi to JK BMS using Bluetooth and not RS485, do you know how to do that ? (any links to documentation and steps to use my rasbery pi and JK BMS together) Thank you

I have the inverter connected in SmartESS and WatchPower using provided WIFI Dongle, but Solar Assistant implementation is not communicating correctly with the device. when plugging in the inverter via USB it's showing up as a "Exar Corp. XR21V1410" serial device which is different from normal...

it is using this RS232 Wifi module that is very popular since summer of last year : http://easunpower.cn/uploads/soft/200727/WIFIModule.pdf

I am using Wifi with SmartESS and bluetooth for JK BMS, I don't have any laptop app and that inverter is not supporting any desktop app.

so if the developer will add it, we will be able to use it... it is so much more convenient to use Bluetoth that is a standardized protocol instead of so many adapters with various cipsets and just one works and the others do not work ... i had spent 2 days and not working just because os...

Is it possible to add JK BMS support by using Bluetooth and not RS485 adapters that many cipsets are not working correctly and is always a problem as opposed to standardized Bluetooth protocol ?

1) Because you wrote the driver for MPP Solar, you have a lot of experience with it, is it possible to connect directly to this wifi dongle of MPP Solar inverter directly and get the data via wifi and avoid cable madness ? It is a lot simplier to connect 9 inverters over wifi that with 9 cables...

Yes, it would be very useful if he would ask for your support because you are very skilled and can help all of us benefit from the help you will provide. Is it complicated to ass this feature to completly eliminate all cables and serial converters ? 3) I would want Bluetooth connection to JK...

1) I would add support for EaSun Inverters with cable at least . I have this model and it is not working to connect USB cable. The Inverter has WIFI dongle and works with wifi on all apps like SmartESS or WatchPower and I want to be able to use the same Wifi network as all the other 6 or 9...

I would like to sincerely tank you for sharing the functionality freely and not asking money for it. We all want to make it work with easun inverters. I will try it and I recommend the creator of Solar Assistant to add support it as a priority because it is a very good 2A active equalizer bms...

I paid for the software, but not working on my EaSun Inverter or JK BMS so I want to find how to make ti work as the software creator is not able to offer a solution for it for 2 days and it seems there are many other people in the same situation. I have the same JK BMS and many others as it is...

Hi everyone. I paid for the product 2 days ago but it is not working for EaSun inverter I have that is the model from last year with new Wifi dongle . I tried to connect with USB B "printer cable usb" and it was not connecting at all because the software that i paid for was showing the device...

Hehe, already checked that and between 24V and 48 the factory only switch from delta to star and I am using 48V so I can't do that ...

Can you send some links with price for one 3-phase transformer from 48V to 240V ? I will need to use 20 transformers (and also add transformer loss) and that might be more expensive than having the additional wires in parallel instead of series.

You had the capacitor where the bypass diode would be on my diagram right? - yes, electrolytic capacitor, with correct polarity All 6 turbines are of the same voltage? -> yes , all 48V You made sure that you did not wire any of the capacitors backwards right?? Because that would explain the...

I have done a series of 6 exactly like you image, with an electrolytic capacitor of 5000uF for each of them in series and without the bypass diode as i was considering 3 of the diodes will bypass if that wind turbine is not spinning. Problem is that 3 of them are always stalling never start to...

I haves asked for solutions so the smartest around can give their solution about how to do this. Each wind turbine will have its own controller that will provide 50V DC and I am searching for solutions how to connect output from wind controller. In series or parallel, series of DC with isolated...

I do think that It will work if i connect in series the DC-DC boost converters but using inputs from 2 separate wind turbines so like that it won't matter if they are non-isolated type because they will use different and isolated power supply ? For example with 6 wind turbines I will be able...

I want to find isolated ones or isolate them with a diode ? https://electronics.stackexchange.com/questions/91609/is-it-possible-to-add-up-dc-dc-converters-in-series-to-create-36v-output-from-5v In an isolated converter there is no ohmic connection (no d.c. current path) from the output to the...

Is there a way to isolate the boost DC-DC converters and use just 2 in series ? Another way is to search and find some DC-DC that can boost from 58V to above 130V . If none will work the only remaining way is to put all turbines in parallel to the bank of batteries and that will work for sure...

Not possible at all, batteries are inside house , wind turbines 100m away, cold does not allow charging at negative Celsius temperature. Also loss is at 20% with so many conversions. Waiting for opinions about the DC-DC voltage booster from 58V of wind controller to 90V than use 2 in series...

Anyone with a suggestion for best way to do this ?

Think a little , not possible to Combine 20 x three phase AC to a single wire of 100m in length !

As specified above cable costs for 200A instead of 40A for 100m in length is what matters and also lack of monitoring from mppt inverter with WiFi

Will this one work to put 2 in series and same input a specified previously? US $15.77 22％ Off | 1800W 40A CC CV Boost Converter DC-DC Step Up Power Supply Adjustable Module DC 10V-60V to 12V-90V DIY kit Electric Unit Module https://a.aliexpress.com/_mPENTDi

Yes, it must be between 10A to 20A input and boost from 50V to minimum 120V and more is better, but they must sustain constant voltage of 40V - 60V to power the wind co troller ( I have seen that controller seems to power on quickly but not sure if thousands of power cycles if it is not...

I already have filled the available roof space with solar and indeed solar is the best option because it produces a lot of energy in one year but wind is complementary because when there is a cloudy week usually there is wind day and night and wind will compensate the lack of sun for weeks...

Hi, thanks for the the answer. Regarding wiring wind turbines in parallel to the same controller it is not possible with AC because wind turbines will slow each other because of different frequency and that it is not a synchronized wave. If you mean to add DC output from rectifier bridge to...

I am searching for a way to connect 20 wind turbines to 48V battery bank, we have 10 wind turbines of 48v and 10 of 24V both are 10A wind turbines. Because distance is 100m to battery I wanted to connect output from wind controller in series and go to 350V input of standard MPPT solar inverter...

same happened with a few thousands of us. Is there a way to find something in AliExpress Terms of Service to force them to provide real shipping information, Last Mile Carrier , practically so that they have to provide a real proof of delivering the product and customs papers, not us that we...

do you have the link to the product that you have bought ?

This hacker also added products with normal price like $700 price for a pack of 4 cells that is in normal range, also added 2 pages of 5 star fake reviews for the product, so it is not easy to identify them, there are more than a few hundred stores like this with duplicated products, many...

Any news you have ? I still see many fake stores on AliExpress and there are still orders from them, so the fraud is still ongoing and no progress ...
