Yes agree 72% is low but over 1 day your results really won’t be accurate and with low generation and consumption your system losses appear larger - it is best to view these stats on a monthly basis. The winter months of December and January are always the worst because of the suns low elevation.

I ...

Hi Steve,

If your HV2600 batteries are 2 years old it is very likely they are V1 batteries - you would normally expect to see a white sticker on the front saying Ver:C or Ver:D

If they are V1 batteries they are rare as hens teeth to find them (you might find them on eBay), but there is a V2 HV2600 ...

Your solar Production was 4.1 kWh (A)
You Exported 1.4 kWh (B)
So your Self-Consumption is (A-B) = 2.7 kWh (C)
Your Self-Consumption ration is (C / A) = 66%

Your consumption was 5.3 kWh (D)
You Purchased 5.2 kWh from grid (E)
Your Self-sufficiency is (D-E)=.1 kWh (F)
Your % self-sufficiency is the ...

The only slot that would charge the battery is the first one, and it wouldn’t turn on because you can’t have an overlap with another time slot (it has an overlap with the second).

To delete a slot, swipe it left and choose delete

thank you for your quick reply this is a screenshot IMG_4067.png


I can tell you what it’s doing, but you’ll have to say if that’s what you intended to do

First time slot from 05:00:00 to 07:00:59

Force Charge, minsoc 10% (not used for force charge but has to be set), maxsoc 40%, FDSoc 10 ...

Hi i’m newish to the forum and i can’t work out how to make a new post but this is similar to my problem.
i watched a youtube video on how to set up forced discharge and forced charged, i set it up as directed but i get an error saying make sure times don’t overlap

i can’t even work out how to ...

Someone has recommended to me that I wrap heating wire round my outside wall mounted battery which has gone into hibernation numerous times this winter. The heating wire is what is sold to wrap round water pipes to stop them freezing and comes on when a predetermined low temperature is reached ...

Hi Phil, sadly the KH series doesn't expose the charge time registers and so the charge card will not work (which is a pain)

What i've done for other KH users is to create several timedate helpers i.e. a charge period 1 start, charge period 1 end, charge period 2 start, charge period 2 end and also ...

The inverter is measuring a current imbalance to ground, Fox say this could be because the inverter ground connections are not properly terminated or there is resistance between the ground and live cables - so a visual check of all connections to make sure that connections to ground are well ...

Yes that is the address from the latest modbus spec and is definitely working on the H3_Pro - so it looks like the H3 doesn’t support this function via modbus

On a related theme, when my EV charger was installed they have wired it so that it now drains the EP11 battery when IOG schedules peak rate charging windows and the EP11 isn't set to Force charge. The installer said he wasn't trained in solar and so could not add it as a separate circuit before ...

Thanks for that info Dave. So if I have got it right only connect to the Meter/CT/RS485 port on the inverter for HA access.


Yes that’s right, it’s a 2 wire balanced connection so it doesn’t need a ground or any power, just an A/B pair.
On the KH inverter you will find RS485A on pin 4 and ...

Yes you should not use the USB port for any other purpose than it is designed for, even on earlier generation inverters that did have a spare USB port - these were only low power devices and not suitable for supplying power to modbus adaptors long term (unless extremely low power)

On the later ...

I'd recommend strongly against editing the automations.yaml file, they really don't want you to do that and it can cause a lot of heartache. I have written code in one version of home assistant, sent it to someone as yaml in a different version of home assistant and it corrupted the automation.yaml ...

Hmm ok, yours is slightly different from the US hybrid manual on their website but it looks like that P2 connector (right hand 3 pins) has an RS485 output that may allow modbus - but in all honesty it also may not, we’ve never tested one of these so it would be useful if you could connect an RS485 ...

Ok thanks, it sounds like an AC1 inverter with your solar being managed by another inverter (or micro inverters).

The shutdown sequence is easier,

On the large rotary AC isolator, switch that to OFF
On the EP11, press and hold the power button for 5 seconds, when all the led's start blinking ...

The dongle (Datalogger?) is flashing about twice a second.
The inverter looks fine (blue & green).
What do I need to do?


The inverter will be working fine, it’s just that you cannot see it in the cloud - a slow red flash means it’s connected (you would know if it was rapid) and approx every 30 ...

Hi, can you just double check your slave version, with the latest firmware I would expect to see 1.03 ?

Your Master/Manager are correct and up to date and I have not heard any adverse reports about generation.

Whenever Master is updated the inverter restarts, but it doesn’t for Manager - it’s only ...

We've never had (heard of) an US H1 being interfaced so far, and looking at the manual there appears to be an RS485 port available (one for meter, the other for modbus?) - can you confirm ?

We have an Error Code 222. Our mobile app is saying everything is off line. Has there been a software update? We have no handbooks so have no idea if there is away of removing the error code and getting back online. Having contacted the installer this morning we have had no response from them.

We ...

Is your datalogger connected via wifi ?, if it is has anything changed with your home wifi.

If it is showing as off-line then the datalogger is not connected to wifi, can you see a red light on it flashing rapidly (or is it a slow flash).

They usually take 24-48 hours to respond, with agile they may need to get their R&D team to look at it which might take a bit longer.

There's no easy way to tell when your firmware was updated, i've just checked and that is the very latest version of Manager for the G2 inverter so it will be ...

7 days after installation. App worked reasonably well until now, but last night it suddenly stopped showing the normal screens and gives me a pretty picture of a house and the instruction "Create a plant", with the message "invalid plant" I don't want to blunder about trying to set up the app ...

Thanks again Dave. Does that mean that if I force charge the battery up to 100% over, say, a 3 hour period using the Mode Scheduler, and it reaches 100% within the first 2 hours, it will then discharge during the remaining hour of the period? If so that’s very different to what I’m used to with ...

If you have the latest version of the V2 app you can click on ‘me’ at the bottom then Contact Us, then Support and you can ad details there or alternatively email fox uk service on service.uk@fox-ess.com - make sure you add your inverter serial number and explain it is a repeatable problem with ...
