Unusual for it not to have been started, must have been left like that from install - which means it basically watches but doesn’t act on anything.

You can also ‘start’ the inverter from the front panel by pressing and holding the ‘tick’ button - if it’s stopped it will say Start ?

Yes agree, it’s only in V1 at them moment - V2 getting better but still a way to go.

Has anyone tried power cycling the inverter, i.e. full shutdown, then restart.?

Checking status is usually seen at startup when there is no grid available, or the parameters voltage/frequency are out of bounds - but you’d expect to see an error reported in the logs that confirms that and you ...

Don’t worry it won’t do any damage to the battery as when it reaches minsoc the battery will charge cycle occasionally so that it doesn’t fall below.

Your date/time must be accurate for the charge periods to work correctly, so hopefully that is now correct.

As long as you don’t have any schedules ...

Yes that’s correct, unfortunately when you have a second source of solar the consumption is not calculated correctly.
If you haven’t already got one, you might want to consider building a home assistant to get accurate information.

I can’t see the setting on that page for protocol it says ‘none’ but should say modbus TCP.

One thing for sure you have the baud rate set to 19200 and it should be 9600.

The ACT light usually flashes as it is addressed, solid on typically means you have the A/B wires crossed - it should be A>A and ...

Great, glad that's sorted.

Best wishes

Lol, sorry Will - we posted together

Yes if the time is wrong on the display the inverter won't follow schedules properly - everything the inverter does is local to it's time clock.

It's unusual for it not to be set by the Fox cloud every day - how new is your installation ?

I've seen on older installs that the datalogger appears to ...

Sadly there's no way to run an ethernet cable to the inverter without replacing your wifi datalogger with a LAN variant.

I'd suggest power cycling the datalogger, it is sometimes needed when wifi is changed - you unscrew the collar, pull it down, leave it 10 seconds and then re-plug it in and ...

Make sure you try them as both input and holding addresses

You might have to do some test reads to see what the H3 Smart is using, the original specification used 41012, whereas the latest spec uses 46616

It may be that Fox haven’t added it to the H3G2 as they have with the KH, it was always strange that they had both power and current limits when it only needed one of them.

Is your ImportLimitCur set to 100A ?

I am seeing latest Master as 1.33 and ARM as 1.22, as these are quite new inverters so I ...

Hi Maureen, have a look at this video which explains how to connect the wifi datalogger - it can be a little difficult but this first video goes through the steps you may be familiar with https://foxesscommunity.com/viewtopic.php?t=970 , this second video is the more up to date way of doing this and ...

Hi Dave,

Apologies for the long silence. My installation has now been revisited by the installer, who of course had my setup immediately to hand on his phone. The apparent fault indicated by FoxCloud was easily cleared by switching off and back on again!

I have contacted Octopus on several ...

It may be your inverter is throttling do to an import limit, check your inverter Settings at the panel in On-Grid, Export Control, ImportLimitPwr should be at least 30,000, and ImportLimitCur is 100A.

There are a couple of effects here, firstly the SoC is calculated by the battery as a best guess of it's actual SoC and when new or out of balance the SoC may jump, make corrections or drop lower than you have set minSoC to - it's not a fault, just the way it works.

Once the battery has had a few ...

So far this year, apart from a cold snap in November, I have been able to set the charge periods to be 2 or even one hour, and the battery makes it through to the start of the next cheap charging period. I don't expect this to be the case with really cold weather.


Storing 1kWh in your battery ...

The rotary DIP switch is no longer used the master will scan the batteries at startup and establish the number of slaves fitted - it should be left set to 0.


For power up, everything should be off to start - then it is battery on first, wait 10 seconds for it do do it’s scan and it will close it’s ...

Been working for me, and is working right now.

I’m not sure it’s a logging problem, SoC jumps tend to suggest a battery pack that hasn’t yet achieved balance, the BMS is seeing one of the battery pack cells voltage fall and is re-calculating the SoC (which is a virtual calculation based on all pack cell voltages)

On new systems it can take a ...

It happens from time to time, nothing much you can do other than wait until it recovers - it’s rare for them to last for more than a few hours.

The main inverter functions have been updated a few times, latest stable versions:
Master 1.36
Manager (ARM) 1.22
Slave/AFCI - same

ECS2900 batteries
Master 1.019
Slave 1.14

Assuming you have a working datalogger installed, you just need to raise a support ticket in the app (Me, Contact Us ...

Ok strike what I said, I thought something had changed so spoke with one of my colleagues.

In the V2 app and V2 web, Fox now calculate load rather than use the load consumption register in the inverter - lots of reasons to do with some users that have corrupt registers and including external solar ...
