Watchpower for windows?

Watchpower for windows?

Hi all,

I've just finally managed to get watchpower for windows to connect to my MPP invertor after they sent me a firmware update. Is it possible to extract the log history from the inverter through watchpower? I know I can extract any logs from whilst WP has been connected but its the historical (none watchpower monitored) logs that I coudl really do with extracting to show the history of F51 faults I've had to MPP.

My understanding was WatchPower only has access to active logging (when connected). I’ve never been able to pull any historical data off the inverters.

Thanks that seems to be the case with me but wondered if there was a way given the inverter is storing historical fault data. Apparently with my MPP, I can pull historical by plugging in a usb stick and holding esc key to access the logs menu but this does not work.

Yeah I know what feature your talking about. I need to get a micro usb thumb drive and try on the 6500.

Be warned that you will need a small sized micro usb stick and it has to be OTG. MPP said less than 4GB and ideally 2GB.

Thanks for the size info. Guess I shouldn't be surprised it has to be tiny...

I ended up purchasing a 2G stick with a micro-usb (OTG) adapter. If 2G is still too big, I know I have a lot of smaller ones floating around that I'll give a whirl as well.

I don't think so...

Well the thumb drive showed up today and I was able to get log data from the inverter. Only problem is that it's just a comma delimited list of numeric values. There's no header information so you can't tell what each value is supposed to relate to.

Here's a sub-set. I can tell the first 4 values are month, day, hour and minute. I'm guessing the 120/121 is in/out voltage and the 59/60 would be frequency.

So here's my guess at the columns:

• Month
• Day
• Hour
• Minute
• Inverter Mode (3 seems to be battery maybe and 4 is grid)
• PV1 Voltage?
• PV2 Voltage?
• AC In Voltage
• AC In Frequency
• AC Out Voltage
• Output Power?
• AC Out Frequency
• Battery Discharge Current
• Battery Voltage (no decimal)
• Battery Capacity (SOC)

You're close, but I think I can help a bit. I don't know all of them either, just going off of info on the inverter and then exporting to compare. Also note that setting 94 allows you to set the logging interval. By default, it's 10 minutes but you can select 3, 5, 10, 20, 30, and 60 (it's in the manual, stating here for readability). There's a maximum of 1440 entries in the log. Once it hits 1440 it overwrites the oldest entry. So, if you select 3-minute intervals, you can get a max of 72 hours worth of data ((1440*minute intervals)/60 = hours logged). The default 10 minutes provides 10 days of logs.

Anyway, here's my combined guess (noting differences in red, confirms in green, and changing to numbers so it's easier to reference in the future):

1. Month
2. Day
3. Hour
4. Minute (Notice the gap between minutes aligns with the logging interval)
5. Inverter Mode
6. Total? PV Voltage
7. Total? PV Power (w)
8. AC In Voltage
9. AC In Frequency
10. AC Out Voltage
11. Output Power (w)
12. AC Out Frequency
13. Battery Discharge Current
14. Battery Voltage (no decimal)
15. Battery Capacity (SOC)

A few notes:

• My "inverter mode" is the same (3) as the data above.
• I have a battery and PV1 connected, but nothing connected to PV2 or AC in.
• I'm pretty confident I'm seeing PV voltage on 6, and PV power on 7. I doubt the schema changes if you connect PV2 (in other words, it doesn't add columns), so I'm assuming it's total, but I don't know that for sure.
• I think if 5 changes, the schema changes. Here's a sample from my data (note that this was before I changed the date/time, it was really like a week before this post):

11,06,09,36,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,00,
11,06,09,36,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,00,
11,06,09,36,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,00,

• In this small sample, note that 1 through 4 are the same and I believe 5 (inverter mode) is as well. However, 5 alternates between 0 and 1 during this time and there are considerably more data columns, but I have no idea what they represent.
• This may have been when I disabled AC output to work on my breaker box, but I don't remember for sure. My main point is that if 5 really is the "inverter mode", if it isn't in the same mode as ours (3) then your columns might be completely different.

Hope this helps anyone in the future. I'd love to get confirmation from EG4.

are you able to see historical data log using the mobile app for either watchpower, Energy Mate, SmartESS? All of them feed off the wifi logger or wifi device.
