Are there alternatives to the UC3845A from Ti. The delivery times are currently at Mouser at 09-2023. Can you take something from STM, e.g. UC3845BD1 or someone else? (component U16 on the boards)

I have had the IGBT Q27, Q28, Q29, Q30 and the Q32 changed (have no Q31). After a try to start with battery pack again came Error 09 at the second start attempt. In another subsequent test, the IGBT were partially defective again. What else can I check or someone has a tip why the new IGBT are through again.

Ho have now been able to test the IGBT as follows. Pin 1 and Pin 2 = Capacitor with 3700pf approx. and Pin 2 and Pin 3 = Diode Uf = 440mv approx. / C = 6.35 nf For me, the following IGBT are apparently defective Q32, Q27, Q28 and the TVS, TVS1 If one is broken everything else comes defective = e.g. Pin 2 and Pin 3 = Risistor 0.00 defective = Pin 1 and Pin 2 = Capacitor 17nf Have ordered the IGBT now and will report how it looks like who I have changed.

I have a new Tester Tool 10$/10Euro with Shipping A pair of values from the components. TVS / SMCJ51A 1.5kW 5 1V - GFZ MOSFET / CSD19505KCS 80V N-CH NexFET Pwr D65 - RHRP8120 8A, 1200V, Hyperfast diode I'm impressed by what the little tester can do 😍 😎 Have a nice day. I will continue to test and hope that I get my fix times.

Apparently some inverters have a short shelf life of my only about 30-60 days geschaft (48V-5kva) only the battery with a maximum of 58V turn. the charging of the batteries ran at that time only over the PCM60x and there were only max 60V on the solarpannel (1600W). I can only ask for photos and reported what was exchanged and was defective on components. So that others also manage to get their devices running again. Error 09 on youtube

current status was with me I still have the D65 - RHRP8120 8A, 1200V, Hyperfast diode has changed but unfortunately did not bring any error 09

Does anyone have a article number / manufacturer for the TX2 !!! Attention, the 48V device !!! According to the service manual, it should be a transformer seemingly with the data ( TX 15:200:15 FER EEL16 ) But at RS, Farnell and Mouser I have not found anything yet and needed your help.

Pin 46 on the Motherboard (the big One) or pin 46 from the CPU Board ( plug-in card ) I can not find this pin 46 where should it be. Or I need a pair of glasses that would be new to me. Unfortunately, my inverter only ran 60 days 😭

Hi Gerlach and Cloulomb. Please also send photos of the boards and parts you repaired. That would help me and others. Coulomb: Which board is the controller board for the soft start? (Photo would be good) Which controller OP-AMP.

Has anyone already repaired the "error 09"? I replaced the TVS which was defective (only One TVS was defective). All other TVS are OK (but still changed) ( SMCJ51A 1.5kW 51V - GFZ ) All MOSFET are OK (the defective TVS has been replaced by the Mosfet) ( CSD19505KCS 80V N-CH NexFET Pwr ) Still get the mistake. Have now ordered the following parts. the - D65 - RHRP8120 8A, 1200V, Hyperfast diode - U16 - IC PWM CNTL - uc3845ad1 SOP-8 But maybe someone has already fixed such a problem with the error 09 Info: I have a service manual from Voltronic 🙄 Top

Build the inverter completely apart. For me he was on the back of the motherboard with the TVS diodes. I have bought my on Aliexpress / shipping from Germany.

OK thank you for the info. Get the TVS Diodes now at Mouser.com. They have the TVS SMCJ51A (identification GFZ). In Germany, the ESD suppressors diodes.

PIP Inverter Error "error 09" bus soft start failed Voltronic Power Axpert MKS5K ISolar SM 5kw 48vdc = EASUN POWER 5000W Solar Inverter 80A MPPT Off Grid Inverter 48V 220V Hybrid Inverter Pure Sine Wave Inverter 60A Battery Charger Need your help. The inverter ran without problems batteries at about 57V (14S) and solar was at zero in time because not connected (solar is connected to the PCM60x). Consumption was at about 300Watt / 230V. According to SolarPI everything was ok all day. But then something must have happened at 16.30 o'clock because the fuses for the batteries and also the solar fuse from the PCM60x flew out. The inverter was of course without batteries. I tried to start the inverter normally after switching the fuses back on. The inverter also starts normally. But reports dan error 09 "bus soft start failed. And the 230V is not there. Has anyone with the error 09 already experience and can help me please. Maybe one of you can help me. On the motherboard, a diode is apparently defective. Designation on the diode is only GFZ without manufacturer and without values. The mounting space is labeled TVS. The board is the new model (with the ID 16-500558-02G) Inverter 5kva / 48v Thanks in advance to all who help me Greetings Dirk Please, please, please Thank you thank you thank you
