Hi hoping I can get some help, I've had a tough time with my installers.
I have two phases of power connected to my house which is why I have two inverters and two batteries with 9.6khw in each system.
Initially only one battery system would discharge but that has been fixed today.
The load reading on the foxcloud app does not change when I turn my air conditioning on which makes me feel like it's not connected to the solar or battery system. They insist it is but have lied already a few times.
The load reading is now working with other appliances connected to normal power points.
I have an efficient heat pump hot water system that used to run off the existing solar system but I believe that is also now not being fed by solar because it doesn't change the load reading either.
The way it's connect I think but cannot prove, is the AC systems + pool pump + water heater are not connected to the new inverters and therefore will not be powered by solar or batteries. This will cost me a lot in power very quickly and make the new system pointless
Should the AC and heat pump be connected to the solar and batteries like the old solar only system? If not, this means when it's the middle of the day and my batteries are full instead of the AC running for free on solar I'll be paying grid power.
Should I see the load reading in the app show the AC and hot water?
Thank you for any help
Yes you should see the load reading change when anything is turned on in the house, admittedly the data samples are only taken every 5 minutes so you need to wait at least 6 minutes to be sure but if it does not change then the load is not being seen by the inverters meter/CT clamp and consequently the batteries would not be used to supply it.
As you’ve got 2 phases running into the house and one inverter on each phase any load on that phase must be seen by that inverter, there are exceptions for example EV chargers tend to be fitted ‘in front’ of the inverters (grid side) so they don’t see it as load and flatten the batteries.
From what you have said the AC system and other devices may not be connected to either of the phases (i.e. they are on the 3rd phase) or they have been fitted in front of (grid side) the inverters meter/CT clamp and so they are not being seen.
Can I just check a few things you’ve said you have 2 inverters running separate phases, but only 1 meter between them ? - does that mean they are operating in parallel mode ? - If they are in parallel they cannot be attached to separate phases, only 1 phase will work in parallel mode which may be why it is not working. To be attached to 2 independent phases the inverters must be running alone with a meter each.
You’ve also said there is only 1 battery, I assume you mean there is a battery system attached to each inverter ?

Thanks for the response, no they are not in parallel mode, there is no cable in those ports.
Each inverter has its own 2 X batteries.
This is a disaster, all my major power usage devices don't seem to be working with the solar or batteries and certainly don't effect the load reading.
Is there a way to see the load on the inverter rather than the app? I'm hoping if there is it refreshes faster than 5 minutes like in the app.
Not sure what I can do
