[523] SUPPORT FOR SOLARMAX PV-INVERTER
Hi, not sure whether I understood the posting rules while posting a tracker first. Appologies if I'm doing wrong!
I was stunned reading about the SolarEdge Support in this forum. Beside a SolarEdge Inverter I'm also running a SolarMax Inverter that comes with a simple LAN UDP-Interface. I've done an implementation in Delphi. All you need to do is sending a UDP request string to the inverters IP on a specific port (12345 in my case). The inverters respons string sends the values of the requested data fields in ascii. This is a example:
Send: '{FB;01;1E|64:KDY;KT0;PAC|0672}'
Receive: 'KDY=A3;KT0=1689;PAC=570'
The values are in hex.
KDY=energy today in Wh
KT0=energy total (energy produced since installation or reset )
PAC=AC current power
There are a lot more parameters that can be requested, however these are the ones that really matter to me. At http://blog.dest-unreach.be/2009/04/15/ ... ent-page-2 a more detailed discussion on the protocoll can be found. I'd be hayppy to do any testing on experimental code or could even expose my SolarMax to the internet for testing purposes. Unfortunatly it's only responding during power production. So no chance to test at night .

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
Could it be that in the forum they talk about TCP ? (Not UDP)
you might be able to write a small bash file that reads the values,
and then send it to domoticz via the json interface
It might also be possible that SBFSpot supports this inverter? We do have an SBFSpot implementation in domoticz

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
You're right, it's TCP. I already wrote a small program that updates domoticz via the json interface. However I'd find it great to have a native support for that. SBFSpot seems to support SMA inverters only.gizmocuz wrote:Could it be that in the forum they talk about TCP ? (Not UDP)

Could you upload your script file ?

Re: [523] SUPPORT FOR OMNIK PV-INVERTER
HI gizmocuz
Would it be hard to have Omnik inverters available in the same way?
Currently it can be done using a script as described here: http://www.domoticz.com/wiki/Omnik_Solar_Inverter
Send a magic packet and the machine will spit out the data
tnx.
Any assisstance needed, please let me know.

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
Same for my SamilPower inverter, I currently use this perl script described here.
I use a RS232 to USB cable.
I'm not a programmer but maybe I can make it more easy to implement, but don't now what suits best for you?

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
Is it possible to get a more exact reading from a solarmax inverter?
Now the day readings are in 1 kWh. Would be nice when it's in 0,1kWh output if not too much trouble

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
I got a Solarmax 3000S
I activate in the front panel the ethernet interface and add it to Domoticz
and nothing...
do I have to do something else?
do I have to implement something?
my Domoticz is on a raspberry Pie and update
don't I supposed to get all the drivers with?
there's 2 ethernet plug in my Solarmax 3000S and description seems to give them both as working
could U help me with this hardware please

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
hi, before i saw the current watt and the total day kwh and total all time kwh , but after a complete new installation i dont see total of all time anymore on the dashboard or utility. the total value is visible in devices.
How can i fix this?

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
One of the reasons I chose Domoticz was the inbuilt support for SolarMax inverters. I connected my inverter and it works really well.
Only problem... when the sun goes down Domoticz continues to try and poll the inverter. See here...
Is there a method of telling Domoticz to stop polling the inverter at certain times of the day, such as during the times where there is no sunshine?

Is this Plugin Solarmax with Lan working for SMT Series as well?

Re: [523] SUPPORT FOR SOLARMAX PV-INVERTER
I had the same issue. I changed the address in the settings of my inverter to 001
Then did "sudo service domoticz. sh restart" and then it worked.
Even though the answer is rather late, i hope it is helpful.
