Inverters

Since SunSynk does not notify its clients of new firmware releases, I would like to start a thread and track the latest release versions of the firmware for the SunSynk models specifically. So, currently I have installed SunSynk 5kW: COMM:e41c - MCU:3367 Please post your inverter model and firmware version, if you see that you are running a newer version than the last one reported in this thread.

This thread is for tracking the latest Deye Inverter firmware. Only post the firmware details here. It is one click to start a new thread for anything else... Format / template: Model: Deye 8 kw single phase Date: 1 June: Protocol Version：V0.2.0.1 Lithium Battery Version Number：V0.0.0.0 HMI：VC.3.5.8 MAIN_1：V6.0.1.4 MAIN_2：V0.7.1.7

Hi, Does anyone know which is the latest Firmware for the Growatt 5000es?

Hi folks, My Growatt has the issue on PV, when the power consumption reached around 1700W from PV either feeding the output or charging the battery, it turns out to PV drop in power and voltage until 0V and 0W, few seconds and the process restart again, and so on. The utility is working well, output is well, battery discharge is well. The problem is only in PV. I debug the MPPT board, it had some teared wires due to humdity, so i fixed them out, and changed the TL072 to make sure the existing one is not broken. I tried out and still same issue. What do you think the problem is coming from? Might it be from other parts in MPPT? or in the controller? Thanks

I need firmware for this inverter I not know the firmware version the mcu MC9S08 is damage

Hi I currently have a 3kw Solis Grid tie inverter on the output of my Victron Multiplus-II 48/5000/70 Inverter. I would like to increase the wattage of the grid tie inverter and heard that I shouldn't go over the rating of the Victron itself which is 5000VA. Ratio of 1:1. Would I be able to install a bigger Solis of 6.4KW on the output of the Victron and then use a Solis current clamp and set the inverter not to feed excess power back into the Victron? Thanks JB

Hi guys I have a raw power 3 kw it gives 01 error and the fans are working fine i checked all the electronic components in the board that are related to fan circuit after that i bring a control card then the inverter worked fine and there is no damage in it's control card so i think it is in the software and i need your help guys to restore to default or install a new software, ? I need the information about the software to install in the laptop and the communication approach and the firmware.. step by step Thanks you in advance brothers

Hi, I got this firmware (50.81) from Sorotec for REVO VM II Pro 3.5 and 5.5Kw inverters and I think it may be useful for someone. The changes include reducing the PV normal operating voltage from 120 to 60 volts; adding a Lithium battery in battery type and other settings that I didn't get the chance to go through. VMII-PRO-05150-08-S1-1.hex

I have noticed that the Grid Export value of my inverter is calculating incorrectly. It is wrongly showing as "Export" + "House Load". This is during Forced Selling mode to discharge the battery. For example, if the battery is outputting 6500W, the house load is 1000W... the export value should be 5500W. However, the inverter is showing export as 6500W! Furthermore, I have looked at the Inverter menu to find the CT reading and that is showing a lower value (5800W), which looks nearly correct. Is this a known bug? Are there any solutions available please?

Hi,I have two inverters that I want to connect in parallel. One is Axpert Mks11 5kw with UI.71.80 and a Kodak OGX5.48 5kw with UI.71.70 firmware. Can I update both inverters to new firmware or just the one to 71.80. Can someone supply me with the correct firmware please.(previous topics I found UI.71.92 to be the newest firmware - can I use it?)

Can anyone help please. I have a Meccer sol-ax-5p inverter and a Freedom One Tower E5000 Modular Lifepo 4 Lithium Battery. My Problem is everything works fine but if the battery gets low and shuts down during loadshedding it does`nt reboot when the Utility returns and I have to manually reboot it. Is the problem just setting on the Inverter?

Hello My inverters won't charge the batteries at more than 100a each 200a combined even with the max charge rate set to 150a. There seems to be some sort of hard limit they won't go past no matter what. Solar panels will produce more power if building demand goes higher so I know there's more capacity to charge but it just won't draw over 100a from the panels

Good afternoon all, did anyone perhaps experience something similar on these units? Axpert king/Kodak . I have replaced the control board and tested each individual component that the 27 page service manual guides us on. Voltage shows 32.5 , and not the usual higher voltage which is confusing. I have another pcb which is completely dead .. I also don't see a fault on it , unless there's a processor somewhere which I didn't locate and probably can't test or replace .

Hi all, thanks for reading. I have a kodak 5kw , came in for error 9 . I found two igbts blown into pieces, replaced all 9. I have also replaced the gate resistors and optocouplers too. As soon as I start up it blows the 470uf cap in the switching power supply , I removed and checked all the surrounding components and can't find a reason why the cap would blow its top all the time . Has anyone else experienced this ?

Version 3.3.0 of the dSolar program supports the creation of your own access maps to modbus registers of various types of equipment via rs485/rs232 -> USB cables. Theoretically, by describing the register map, you will be able to monitor the equipment in real time with a second interval. All your data is stored directly on your equipment. No extraneous rain clouds Tutorial video on creating maps: https://youtu.be/785g92ziwAo Documentation for modbus map: http://doro.poltava.ua/dsolar/index.html#Modbus%20map dSolar program website: http://doro.poltava.ua/dsolar

Hello can any one share schematics of the below inverter board And the below is it's microcontroller side card which is having the sg3525 ic, can any one tell me how to activate this ic biasing on gate manually.

i was using my cheap, noisy and unefficient chinese AIO [a voltronic clone VM 1000watt] for a mini fridge(40w nominal wattage n 1,2Kwh per day consumption) n charge my e-moped (72v battery charger user 240watts) upgraded to Pheonix 12 500 Schuko (surge is 900VA) n when i open inverter even red led doesnt light. It just goes offline. Is there any simple fix (like a supercapacitor)? i dont want to use 12 800 or 1200 cos cabling gets too thick. (i checked all cables, fuses n breakers work with cheap inverter)

Hello, I want to check the gate signals with oscilloscope before installing the mosfets, can any one tell me how to start the SG3525a ic switching. Thanks

I have one of these trolley inverters bought from takelot almost 2 years ago. It has not skipped a beat in this time however last week there was a power dip and power returned immediately. The inverter started sounding an alarm continously with all lights flashing. Does anyone know what the issue might be and how to reset if possible? I dont think this thing has broken all of a sudden and would rather not send it in for a warranty claim. It feels as though there might have been a surge and it went into some kind of safety mode. It looks like this: https://www.makro.co.za/navasolar-nv-bp18-1012-pure-sine-wave-inverter/p/itm353aa6eb543b9?pid=IVTH7M76SCGXGSRZ&gad_source=…

Hi Everyone, Just wanted to share my experience with the RS485 port on my DEYE 16kw. In December the DATA coming from my inverter stopped working, I wasn't getting anything coming through. I initially thought it might be a faulty RS485 board as the ESP32 was running without issue and I swopped the board out for a new one. It made no difference and was still not getting any data. I tried using the battery's BMS port and split it into the CANBUS/RS485 ports which worked. I assumed that the RS485 port was faulty and stopped in to speak to the guys at DEYE who are luckily located about 3km away from my house in Kyalami. One of the eng…

Hello everyone! I live in a region where it is very hot in summer, and the infrastructure still leaves much to be desired. To solve the problems with the lack of electricity, I installed a solar power station. But I assembled it with a reserve (about 3 times more than my needs) for cloudy or short winter days. I also planned to export the surplus to the grid. For about a month now I have been struggling with: too hot air around the inverters (the outside air temperature is over 40'C) Because of this, both inverters overheat (the temperature of its sensors reaches 70-75'C) and, as expected, begin to throttle. One inverter produces approximately 80% compared to the time whe…

Here are some schematics that I reverse engineered from Anern Victor Max 10.2kW inverter. Should be very similar to Axpert VM models. Of course, part references and connector pinouts are different. Also ADC and GPIO assignments do not match genuine Voltronic's. The SCC board schematic is complete - PV boost circuit, voltage and current measurement, AC power supply and bus soft start circuit. Then there's a schematic of the two power supplies on the main board - this inverter uses an auxillary 150V power supply to start from the battery. Also a I attempted to trace the analog part of the control/DSP board. This was little bit harder as there were no printed part references…

Hello to all hardware hackers and software reversers from this forum. In the rush for cheap inverters, I bought a clone inverter of the Infinisolar V2 Daxtronm BGH-5KW. (looks exactly like Easun SV2 (Infinisolar V2) - a model very popular now in my country. The only difference / problem that I noticed is that it does not work without batteries connected. If I have only AC IN connected, as soon as I turn ON the AC out from the power switch it shows error 09 - bus soft start failed. It does not go into bypass mode. I had a look on the schematic diagram (many thanks @Coulomb- great work there), i also did a side by side comparison with EASUN SV2 (Infinisolar …

Hi all. Have a deye 8kw inverter, the wifi module doesnt power on. Bought a replacement module and the same occurs with the new module stick logger lsw-3. There is a small board inside the inverter, that the module connects too. Where can i buy this module? Im assuming a capacitor went or something. P.S. the solar company i us3d is not interested in assisting me, inverte is about 11 months old and logger not working for 2 months now.

As per the subject: I would like to know if anyone started a project of collecting local data from a SunSynk WiFi Dongle? I am sick of server-outages and lost data and am thinking of either hi-jacking the traffic (on my router) to SunSynk's cloud storage or cracking open the dongle and re-programming the NCU chip... My Question: Has anyone thought or started something like this? regards Aubrey (aka cyber7) ps - as an afterthought, this could even work for that "other" dongle we all got with our systems for free
