Hi all,

Does anyone know why my SPF 5000 ES Growatt inverter suddenly started showing 2 warning messages every day at midnight? The first is "(5009) Grid phase error(Warning)" followed directly with a second one which is "(5011) Over temperature(Warning)". Everything is working properly and no hardware failures or problems. More details are written in the first topic I shared before.

Hi Hussein,

I have exactly the same problem.

How did you solve this?

Thx

Hi @Mak,

I wish I knew, but the problem still exists. If anything may help, read my other topic with the title "Error Code 02". More details are written there.

I have the same problem. I installed the inverter SPF 5000ES two months ago. Suddenly it is reporting Grid Phase error and High temperature (code 02). Restarting it did not solve the problem. Although, it is working fine. Had to disable the buzzer though.

Hi same issue, although my inverter is not working now... Batteries have plenty charge / power showing 52 volts... 

 Just see a plug picture on the top left of screen and got the same errors as Hussein... Any suggestions would be appreciated.

Hi, has anyone been able to resolve this ? I am seeing reports of corrosion on board tracks in some the other threads as the root cause, but they are not reporting the Grid Phase error.

If I cycle through the display options to the one showing the grid input frequency, it's often below 50hz, especially when the grid comes back online after load shedding. I see it as low as 49.7hz.

From what I see in the documentation, the device is rated for 50hz - 60hz.

It stabilises after some time to 50.1hz. I don't have enough data at the moment to support that the low grid frequency is potentially a problem.

My inverter will show the error a couple of times a day and then it's fine. It does not appear to be related to temperature or fan failure, at least for me.

Welcome to the forum.

That low frequency is likely to be real. After load shedding ends, the loads on the grid are very large; lots of refrigerators to get cold, compressors run till they build up pressure, etc. In the first second or less there is an even larger load as transformers magnetise, capacitors charge, incandescent lamps heat up to operating temperature, motors start, and so on. With such a large load, the generators are overloaded and slow down the grid. Eventually, the load is manageable, and the frequency is more normal.

There are two nominal frequencies in world power systems, nominally 60 Hz in North America and a few other places like half of Japan, and 50 Hz in the rest of the world. But the exact frequency could be plus or minus a few percent, depending on the exact settings of the generators. 49.7 Hz is only 0.6% low, which is not too bad. Your inverter should be happy with that. The grid frequency should never be between 52 and 58 Hz, however; always clustered around either 50 Hz for South Africa, or around 60 Hz for North America.

Hi there,

my Growatt SE 5000 has been showing the same problem, after exactly one year of been installed, as Hussein described. I have contacted  my supplier that is Autosolar in Spain, after checking the inverter they just sent me a new one.

No details or explanation about what nor why error 02 happens.

I wonder if a new serie of the device with that problem solved has been or is in the process of being built by Growatt.

Any idea?

Would be interesting to know which series of the 5000ES this problem manifests itself?
I have recently added a new 5000ES in parallel to my older 5000ES which was installed Aug 21 and the new one runs 10-15C warmer than the original one.
On closer inspection I found that Growatt in their "wisdom" changed the airflow direction.
The old one sucks the air in from the bottom placed fans and blows it towards the top.
The new one blows the warm air out the bottom, i.e. sucks it from the top.
Now these Inverters are marked as Version 2 and Version 4 respectively on the front cover of the manual and there seem to have been 4 Versions of this same model number ever since the series was launched.
Up to Version 2 the Firmware versions were the 04X series.  Version 3 and 4 had the 06X Series Firmware and the latest Version 4 have the 114 Firmwares. All a bit of a mystery what else has changed between the Versions
@Lusan perhaps you can check which version of Firmware your Inverter has. It may well be a temp threshold limit that alerts at a too low a temp and it may be particular to just a series of Firmware.
Mine doesn't have any warnings and the temps now in summer are as follows:  Inverter#1 being the older one.
Something else I noticed is that all the posters seem to have a grid feed which is absent on my installation.

You can contact Amos Yang on email or whatsapp, the International Rep in China and give him the full specs of your Version and Firmware and see if there was a known issue and if that has been fixed in the meantime. He is quite responsive with feedback.

Hello @zsde my two usually max temp around 36, see last three days.

That's the typical temps for my original Inverter too in summer.
I am so tempted to change the fan mounting plate on the new Inverter to change the airflow direction, but that means opening it up which will void the guarantee
