My Home system, with net metering

My point of view, and going back to the original post, i don't really see the need to closed loop monitoring and/or control because of one basic thing: SOC is a calculated value and over time it needs to recalibrated or recalculated so i don't find it useful. On the other hand, voltage is as...

My first connection from a xw6848pro using node-red with the modbus nodes. This is from the node-red dashboard. This is fun !!!

You are a savior ! Thanks for pointing that out. I downloaded the file.!!!

I am using vb.net and Easymodbus dll to try to create an interface for the schneider equipments. In this first successful try i read register address 0x00 of slave id 70 ( my SCP) using Modbus over TCP, and it was great !. Posted a little picture of the event! Do you think there is any future...

And i was thinking i was clear ! You nailed it !!!

Too late ! I already cried a river trying to get the meaning of things, but not to worry, tomorrow is another day !!

Just a big hit !! I just changed Grid Support Voltage in Inverter settings from 54.6 to 54.5 volts and the system suddenly release the 3kv pv limit that i was having and increased to 5kw solar !!!. I set max sell to 20 amps and got a max of 3.9 kw sell to grid, aprox 16.25 amps !! That is...

Thanks for the suggestion. This is my first attempt to this type of programming. I am not a professional programmer but like to make things work. I have done some applications in vb.net with sql database connections and client replication also. I am going to look for the nano-10 since i don't...

I have the ones in the picture attached. Are there any others or more updated? Thanks

A small update, more registers seen !

Those are my actual status pages. I did full factory reset, then connect LAN cable from router for initial setup, configured AP Ip and password, and lastly configured wi-fi ssid and password.

I was so infuriated that i put 1.17 back and everything worked good, buuuut now i cannot write the Region Code. I dont know if it is related or not but when i try it says: stored successfully mut in status says: State: Mismatch, and Current Region: Custom!! I am goig to a short vacation with the...

as sancsam said it coul be a cloud problem and not mine, anyways i will not try it again as I cannot get my Fortress Evault Classic to use closed Loop !

My DC coupled system have about 7.9 kw pv for two schneider mppt 60-150 that generates about 6.5 kw ( 120 amps x 54.4 volts). I have a xw6848pro at fw 1.11 and a Gateway at fw 1.17. When i was in grid support-zero sell mode the system charges the battery to full 54.4 volts, no matter the GSV...

Thanks for replying. Your first paragraph describes exactly how my system is working. Because of the current heat wave here the utility bill went up a little and my plan was to try to use battery power after the sun comes down and cannot do that by lowering the GSV as i could before with sell...

Does it matter that i have the charger of the xw disabled? Also set to cold in the mppt's and the xw?

Thanks for all replies. To clear things a little lets use SOC for a minute ok? If i set GSV to 99-100% SOC when the sun comes down there is no use of the battery to supply loads as it is already at GSV. That is how i have it now. Second case: i set GSV to 60% SOC. when the sun comes up it...

There are various voltage across the system. First The battery recommended float voltage is 54.4. Measured with a Fluke digital voltmeter at the dc bus is exactly as the battery and exactly as the battery integrated display. At the mppt's it is 0.1 volt above; 54.5. At the Inverter display in...

Thanks for you time. My system is in open loop, so no soc. I am fighting with the Fortress Power people because their modbus interface with the gateway is always showing positive current no matter if charging or discharging. soi disconnect the interface and reset the gateway to factory and...

Hi there folks, as this is my first post I will try to explain the best I can. My problem is similar if not the same as romangeek. Firts my setup: xw6848Pro,two conext mppt 60-150 for a 7.9 Kv pv array and a Fortress Power Evault Classic 18.5 KW Battery in open loop(the interface with schneider...

Thanks for the input. For your recommendation i will have to change the inverter battery type to Custom. Easy Peasy. But first I will try to re-flash the previous firmware 1.11.01 build 49 to the inverter. I have not tested selling before with this previous version bacause i was waiting for...

I just did the update to 1.18 and lose wifi, access point, everything. Had to remove and do a factory reset. It said something like that in the fw readme. But now i dont get internet access. Dont know what else to do. Gracias ! I did reset my lan access point and my switch also, just to be...

Please clarify some points: are you using equalization for LiFePo batteries? and second: where exactly is your 56 volts setpoint? Thanks

I am trying to input you json file but there a re some nodes missing and for the life of me i cannot seem to find them. Do you have an updated list for the nodes that have to be installed. Thanks. I am in node-red v 3.0.2

Will try to look into Javascript then Node-Js and then Node-Red as apparently is the roadmap to understand this stuff. I have only used vb.net because it was the first one I learned about a century ago! Then a bit of html,css and asp, That is all !! Time to expand horizons !!!

Just installed node-js and node-red and finally made a connection to read one modbus port ! excellent. It was easier than expected. Now my problem is that i cannot stop the flow once i deploy it !. Maybe next time !!

I have two raspberry pi 3+. Is your solution using node-red your own or openly available? I am interested in exploring all avenues. Thanks
