Hiya. i re-tested the meter a few times today and all is well, meter read OK when tested so looking good.
Hope you don't mind re re asking.
Ref the Chint PT , it is currently set to "1" after reading the Chint instructions i wonder if "1" is correct?
I am still a little concerned about the Gid value. currently there are no electrical items on in our house, no TV, Washing machine or Immersion etc, yet we seem to be pulling 1.29KW, Batteries are at 10% Min SOC, any idea?
H3 Pro issue- Power from Load icon

If the batteries are at minsoc they will be cycling to maintain their 10% charge as they are slowly draining to power the inverter so they will be on for 10-15 minutes hour, off for an hour so and will repeat that until they get well above minsoc and with 2 batteries you can easily take a couple of kw's.
The thing to remember about the power flow graph is it isn't real time, it only updates the data every 5 minutes so you are mostly looking at an old snapshot - the better way to look at usage is on the website and see how the trend is changing across the day - it also shows when the batteries are charging (or maintenance charging) which might help to explain the grid usage - it's always better for the batteries to be charged above minsoc or you'll see the charger coming on occasionally and with 2 batteries even more often (you also get the affect when the batteries get very cold but it's mild at the moment so won't be that).
I'm not saying for sure that's right but it does appear to be working correctly so perhaps the ideal time to measure your loads with either the clamp meter or even better if your electricity meter can show the cumulative phase power being used that will be the most accurate answer you will get.
On the Pt setting, that is referring to the voltage (and not the current ratio which is the 40) - the voltages are read via the L1/L2/L3 which are connected directly to the meter and so the ratio is 1.

Morning, just thought i'd check in and see how it was running - hopefully a slightly better day with some solar so you might get some charge in the batteries.
The one thing I hadn't asked before but now it's settling down I will, is, have you updated the firmware to the latest?. The H3 Pro is a very new inverter and there have been a number of releases to correct bugs and issues, so can you check your firmware is the latest.
At the top of the energy flow page where it shows the serial number and site name there is an arrow on the right hand side and when clicked it will list the Master, Slave and Manager versions - latest versions available are Master 1.56, Slave 1.06, Manager 1.25

Good Morning. all seems to be well this morning, thank you so much.
See the image below of the firmware.
Master 1.31 Slave 1.06, Manager 1.15
I did think maybe the the firmware might need updating but i looking online and could not see how to update it.

ok great, be nice to get some decent charge in the batteries, I can see from your graphs they were taking .8 kw charge for quite a while in the early hours to maintain their minsoc's and keep the inverter operational - thursday's solar forecast is currently looking a bit better but there's not a huge amount about at this time of year.
On the firmware, yes definitely update it - but wait until you've got a spare hour as it's a bit clunky and you have to go in and out of the website to do it.
Always update the Master first, then the Manager - you can do it on the website using your agent account, click on the Firmware Management item in the menu, then 'Inverter Remote Upgrade', you'll need to enter your inverter serial number in the box at the top, click search - select your inverter, and click 'Upgrade' on the far right.
Give it a task name - 'upgrading Mas to 1.56' , select Master as the firmware type, click on the Firmware version box and it will show you the versions available select 1.56, change the timeout to 45 seconds and click upgrade - It will go off and download the upgrade, then verify and apply it which takes 10 or 15 minutes,
You can check the status by clicking on check upgrade status and it will show you what is in progress and when complete it will say have a '1' in the completed box - when it's done a successful download the inverter will restart and that's the Master done. It does sometimes fail if the comms is interrupted or they have a server issue - you just have to repeat the process until it is successful.
Wait for the Master to be done, but as the website takes 5 minutes to update it may be 10 minutes after the upgrade before the version is shown as updated, you can check in the inverter panel in the About screen what the inverter thinks.
Once it's done and confirmed you repeat the process for Manager, task name 'upgrading Man to 1.25', Select Manager as the f/w type, click on the box select 1.25, change the timeout to 45 seconds and click upgrade and off it goes again - the Manager usually takes a lot longer ~ 20 minutes.
And once done you will be on a much more stable version.

Thanks so much, it is now all updated.
lets hope for some sun later this week.
FYI of the 52 panels we have, only 7 on one mppt and 6 on another are currently connected. the other 39 are due to be connected early January. today for a short time we pulled in circa 3kw.
before we had 2 x H1-6kw with 42 panels and all worked great. the 2 invertors ran 2 of the phases, but now all 3 phases are on the new 3 phase H3.
a few screens shots for you to see the latest info.
