Esperyd´s Raspberry PI project
#31
This sounds promising. I will run in next days my EPever active and we can look how to fetch some data with pymodbus inside influxdb.... i do not understand for the moment the way how to use pymodbus and how to send the data to the right adress. from the modbus protocoll. Maybee some video with some example of configuration will be good exact at this point a step by step procedure. Collin talk in his video about pymodbus and than in the git link he use a php libary but no description. I saw only from the manufactorers given modbus protocol and i saw that pymodbus handle this somehow but its not clear the steps.

For this i am not educate...

UPDATE

Have done several changes to the ISO. 
* Sorted better logging for the services including better log rotation 
* Batrium service is now autostart and as a service
* The SDM630 meter service is also autostart as service
* Alot more coding done for the new npm package for the RS232 package for inverters are done. This will make it very easy for building your own reader/sender for any inverter or charger that runs normal RS232 text protocol. Like all MPP stuff including others like EPever.
* PIP + MPI hybrid is partly implemented in terms of the protocol in question


I will be uploading a new ISO soon but except the NPM package for the solar. That one need some more testing and tweaks first before i will release it.

i did not got any news. Meanwhile the GTILV2 did arrive but i have only a smal sheet with just one panel and they did ship the bigger inverter with 1000W 45-90 V version.

I like to run maximum 24 V because of the epever that only can run 12 or 24 volts.

Do you think as here described is way? For the Raspberry pi?

i think yes... but for me is not clear how to get the data from the phyton libary inside influx... in general needs not all parameters involved for an example but for a programmer noob like me 1 or to examples of data and more important is the way i think... most go the way with socat. 

maybee you help with such a way description for people like me and act a bit as mentor than.

i did register a sourceforge place also for to store the image than but  realy to start i need a mentor to learn first steps...

PS. Yours valence batteries where you get them used? i look arround europe because of shipping but nothing to get used...

The video below is a brand new boat what did have a little problem with LiIon batteries and i do not wish this happen...

Where does it say the boat had liions onboard? There is no audio nor any information in the description.

Was in Germany and the Boat (solar driven) owner did describe in the boating forum for his new boat some month old that that some problems did appear with the batteries. And was Liions. After the fireman did enter the boat because of smoke 16 where injured and if you youtube search minden boot explossion you find some videos. A drone owner did saw the firemen and did this illegal video (because its forbidden drone flights in the night and this complete explosion is impressing.... no gas or something else at the boat. Thread in the forum was suddenly blocked to prevent the owner in front of inshurance things. The thing was that in the forum discussion in the afternoonwas announced for the next day that a electision of the company that build the boat was ordered. to late as far we see.

I think lipo with used batteries in a boat where is not a good idea. so the idea for the valence batteries (used ones) can be reasonable. but in a small powerwall with just 2 batterieies maximum 4.  if i get used 4 used ones for my steal boat each 130 or 138 AH can be reasonable. If i pay 250 Euros for one than the batteries have the double price i did pay for all the boat :-)

lion powerwall i like to make first experience but if available valense with fe are the better choice i thing or i have to go ordinary AGM gel batteries for boat.

for the moment i focus just for the monitoring with the raspberry as long there is no decition ade.. same for home and for the boat

Sounds to me like the person who built the power setup didn't fully test each cell and potentially just threw cells together. Or, he had a failing/failed charger that over charged the cells. Or, the charger worked fine, but the packs where in the wrong series (ie. 24V setup but used 6s instead of 7s or something similar, which resulted in the charger overcharging the packs). Or didn't have a proper BMS installed. Or, the wiring wasn't separated enough and there became a short somehow and high amperage caused overheating.

These things don't just blow up without some sort of thing usually external causing them to do so. Someone could say "Well, the Samsung phones exploded". Yeah, but it was shown there some defect in the manufacturing process or they were damaged. Those were "new" cells.

The reason why I say something must have not been done correctly, is because several members on here have tried to force failures. And most have failed. I say most, because the ones that failed were super extreme; like taking a blow torch or air heating gun and heating the cell to well beyond what it was designed for.

However, in all things said, I hope the firemen were ok. It stinks for the boat, and the boats next to it.

Anywais its not the topic. I saw just Valence lithium iron batteries in Daniels Video and do not know where he got them. And a price level here is not talked. Should be a good solution for me.

Back to the topic...
I did change the passwords in the build but did expose it in the internet and runs approx 3-4 days and than seems to be hacked... Idea was that daniel can develope with time on real EPEVER and SUN GTIL-V2 1000 (the Model of 22-65V and the Model 45-90V).

Anyways its now second time i can no more reach the unit. That way i do suggest for the moment not to use this img with internet access. I have 2 Internet lines and one is seperate only for such tests. I will check stability now without access to the Internet until Daniel have time to look a bit deeper inside...

First time i did not change the passwords but second time i did change them all because of the Webserverpage with the data.
