The H3 has something called grid compensation which is the same thing, it's a bit more complex with 3 phase, sadly i'm not an expert on the H3 but in essence every installation is different and you have to set it and check, the aim is to reduce the small import that is needed to balance the loads or ...

Hi, the price looks ok - some of it is driven by the amount of scaffold you will need if you have multiple elevations, but it doesn't seem unreasonable.

It is better to slightly over power the inverter as it is unusual on multi elevations for all panels to be producing full power at the same time ...

Hi, your versions are quite old and one of the early things to do with new installations is to make sure they are running the latest versions of firmware.

Fox do not provide release notes but the latest versions are the more stable, as a rule it is not possible to downgrade but where a problem ...

i've just released v0.45 which introduces this last fix to catch the 162 holding state - enjoy

Separately, since the HV batteries are connected essentially serially, is it not harmful to then push up to 50A constantly through each battery and maybe also through each and every cell. In an alternative low voltage setup, say 48V, there would be high degree of parallelism in configuration with ...

There have been a few cloud issues of late but all have now been resolved.

The timestamp must be within 1 minute of UTC time, and the most usual candidate in these cases is that your internal clock has drifted just enough to be outside of the 60 second window.

Check to see if you ntp service and ...

Yes it can do all of that, if single phase you would be looking at the KH10.5

Batteries can be added to get over 40kWh capacity (either EQ4800 or EP11)

The inverter is wired in parallel with the grid, it is grid tied and works by measuring the load at the incoming grid feed and maintaining a ...

What I would expect to happen after 05:30 is that the batteries would immediately start to be used to cover the house load (plus ~100 watts ti run the inverter/batteries etc..) but nothing should be exported to the grid - is that the phantom load you mean?

Then in the morning when the solar ...

Yes that is underrated, it should be at least a 50A breaker - you’ll need your installer back to fix that.

Disable any force charge you have set and then turn the breaker back on again.

You can do a temporary fix to throttle max power the batteries are charged at, you’ll need to know your battery ...

The traces you have posted don’t appear that unusual, although i’m not sure what you are trying to do with the 2 schedules that set self use from 05:30 to 16.15 and 16:45 to 23:30.

If you are setting a minsoc of 70% the batteries won’t be used unless they get above that value when charging from ...

Yes that setting is correct, it is simply the number of batteries attached in the chain so a dip switch setting of 0 is 2 batteries (the minimum) then it goes up as n+2.
A setting of 1 means 3 batteries - it’s not a setting the should be changed as it is set at install and if set correctly it will ...

Hi @Dave Foster
Thanks for the warm welcome and the additional info.
Are you aware of any guides on wiring the waveshare to the Meter/CT connection?
I have the H1-5.0-E-G2 inverter
Thanks in advance
Will.


There is this one, not sure if you’ve seen it yet https://github.com/nathanmarlor/foxess ...

The easiest way to deal with this is to make sure the EV charger is connected in front of the inverter so that the inverter does not see it as house load and won’t discharge the home batteries into it. This could require a bit of re-wiring (usually a henley block) to split the feed to the house / EV ...

Hi Will
Do you know if they are different in version(s)?
Or should I get the firmware updated to the latest?
If so, is this something I can do myself (reasonably confident electronics and software engineer) or should I get my installer to do so?

By the way, the numbers displayed by the FoxCloud 2 ...

The solar inverter can only be connected to the grid side, it is meant to be a grid tied inverter and will only operate in that mode (without a considerable effort to design an off-grid system)

Hi welcome to the forum.

The Waveshare adapter is an excellent product but as you say it is not really meant to be located externally unless you mount in a waterproof ABS box.
It can just as easily be mounted indoors and wired to the inverter, it is wired using a single pair (RS485) which will run ...

Do you have the V2 app setup?, could really do with seeing an image of the ‘house’ screen which shows your current load, grid, battery

It will also show your workmode which should be Self Use for normal running conditions.

Finally the Quick Settings screen will show whether you have any charge ...

The solar will always cover any house load first and then charge the battery if you are in the normal Self-Use mode, any surplus over the maximum battery charge power or if the battery is full will then go to export.

If you change workmode to feed-in the solar will cover house load first and then ...

No only one user per system but you can use the same credentials on multiple devices

It’s probably still registered to the original owner - did they leave you their username / password anywhere by chance.

Failing that you will need to email Fox service with your inverter serial number (not the data logger sn) explain you are a new owner as they will have to de-register and re ...

As a rule you don’t have to change the work mode back to Self Use after a schedule, it will default to that anyway.

The only time you might want to have a self use schedule is to switch the minsoc back to its normal value - for example you may have changed the minsoc in a schedule to 50% (rather ...

Temperature will be playing a part, it looks like you only have 2 batteries ECS2900? - a stack of 2 has a nominal voltage of 115v so at maximum performance (25C) they should supply 4.6kW but if it’s 7.5C that will likely be reduced to around 1kW.

Updating the firmware on both inverter and batteries ...

Do check the inverter the BMS and the inverter maintain separate values - the inverter sets the normal rate and the BMS the max allowable rate - the lowest one wins.

The settings look ok, the charge power is how much power the battery is giving up - it should comfortably meet your house power at those loads.

You can see what the maximum allowable is from the BMS by clicking Device, Inverter, Detailed Parameters, Battery Information and scroll down to the bottom ...

As a rule that appears to be in the correct position, can you identify where the brown/blue cables are going bottom left hand corner entering the white silicon sealant, and also behind it there are a pair of grey wires - are they heading towards your consumer unit.

Assuming it is wired correctly ...
