Firmware versions

Details of the IES installation

  In response to my Question to Samil ...

Can you please clarify/verify the firmware versioning, as it appears our new inverter has a later version(v1.10) than what is contained in the RAR file you sent me(v1.2)

(The original inverter was v1.02)

As an aside, the new inverter (running firmware v1.10) continues to mis-record values on a sporadic basis just like the first unit;

One sunny day (about the same amount of sun as those either side of it) the inverter decided to record 0.04KW for the day!

On three occasions now, it appears to have not reset the previous days total and continued to accrue the subsequent day’s generation to effectively have double the normal value on the second day!

I haven’t even bothered to try and re-connect it via WiFi/LAN to log the data as it will not stay connected to the network long enough to be worth my time!
Regards Colin

The Samil response was ...

 Hi Colin,

The v1.2 is the latest firmware version which fix the power record issue.

I admit that the R&D is working on the wifi dropping off randomly issue right now.

The temporary solution I recommend to J is to monitoring his system via the VIplant, which is a more stable firmware.

My reply was of-course ...

Thanks M

I may have a go at the firmware update this weekend then.

I must reiterate that there is ABSOLUTELY NO POINT TRYING TO USE VI-Plant because THE INVERTER WILL NOT STAY CONNECTED TO THE NETWORK let alone communicate with ANY monitoring solution!

It physically stops communicating until you reboot it 
Regards Colin

 A very brief update to say I've now had two other Samil owners email me to share their similar stories with me.
To one of the senders I replied ...

It’s nice to know its not just me!

I too have been rung by MikeZhang and have this MASSIVE email trail between us.

He has taken my early reports to the devs and I too got told to use VIplant instead of the browser solution ... despite me explaining at-length that the inverter won’t even stay on the network long enough to use VIplant ... quite apart from my having already set up an account and tried VIplant with total non-success.

In short it doesn’t seem like they want to recognise they have a problem and keep telling me to upgrade the firmware using  “the latest” rar file which they emailed me which I can’t seem to get through to them appears to be an EARLIER version than what is on the replacement inverter I had swapped-in by my installer!!!!

Am I frustrated ... you bet I am!

Having paid as much as we have for a supposedly “automated” system which I have to manually record each day and even then with the second unit every so often it records some totally erroneous daily value like 0.04KW on a sunny day or conversely 53KW+ on a partially cloudy day when the best “real” value I’ve ever seen is like 39.37KW on a totally sunny day!

I can only hope you are right and with more voices Samil will finally try and fix the shonky firmware!

Do stay in touch and I’ll try and update the blog when I have new info

Please Tweet/Facebook/G+ about my blog to get the info out to other Samil owners

PS

I take it you did see all the pages I put up with all my research and findings?
