PIP Inverter Error "error 09" bus soft start failed

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.

Thanks in advance to all who help me

Greetings Dirk

Please, please, 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

That's why I suggested a generic TVS ...... in the absence of the exact specification.

I do not quite understand that with "generic TVS".

Can you tell me one (Type Manufacturer Model) and link.

:huh:

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.

Interestingly, there is only 1 GFZ and 1 SMCJ51A listed in the pdf as well.

How best to test the things / TVS. - I have a multimeter
- not an oscilloscope

Built-in testing or desoldering does not matter
- Soldering iron is there
- SMD soldering station too

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All MOSFET are OK (the defective TVS has been replaced by the Mosfet) ( CSD19505KCS 80V N-CH NexFET Pwr )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 :huh:

Hi Dirk, just curious were you able to fix the easun inverter?

Had the intention to order the same inverter but have doubts about quality & reliability.
So might stick to MPP solar of pay premium for Victron.

Franky the inverters you buy from easun and mpp solar are both manufactured by voltronic. They are exactly the same. That is not sure for the service they provide.
