Hi all - I’m currently researching my options in relation to having solar and battery storage installed. My current preference is the AIO-2 and Gateway-2 but I have a couple of questions that I’m unable to find unambiguous answers to and so would like ask here please.
The Gateway-2 has the ability to split the house load into a General Load and Critical Load (as well as a smart load). I know the critical and general loads have different capacities (9.2kW & 18.4kW) but the question is, in the software do both load types have similar config options in terms of how the AIO/Gateway handles each load? i.e. Can the general load be configured to automatically stay active during a grid power cut (assuming the current load is within the max output capacity of the battery), the same as the critical load?
Also, a second, unrelated question - Does the IOS app provide push notifications for things like a grid power cut or battery SOC warnings?
Many thanks

Hi Paul, perhaps a question for you if you and the team?
The loads are treated like this in a power cut
Power goes off and SOC is 50%
Youve got critical load set as 20% (Default)
All is fine and everything is powered.
At 20% the Main load is shut off and only the critical load output is on for the last 20%
If you want Critical and General to behave the same, set the SoC cutover at 4%
But why bother having them seperate.
Critical loads is designed for home lights, a small ring main with internet, an office, etc etc
Smart load is the other way around.
Smart loads can be configured to be turned on and off with:-
Manual setting on/off/auto
timer with scehdule
Auto on SOC reached eg 95%
So making it ideal for water heaters
Push notifications is not an app thing, its server side and is being worked on, to prevent false notifications

Thanks for the reply - that’s useful and good to know.
My question was based upon having a consumer unit that, without a major re-wire, doesn’t have the ability to easily split out a critical load, so I wanted to confirm that if the entire house load was connected to the general load (with the higher capacity) it would stay powered in a grid outage.
My other option is to connect the house to the critical load but split out the cooker circuit (electric hob, oven and microwave) to the general load given that it is the biggest load in the house.
Regarding smart load - is it configurable to switch on only when there’s excess solar and the battery SOC is full? I’m considering powering the immersion that way.

The whole house will remain powered.
If not using critical load. Set the critical load switchover to 4%
Ie notused.
Whole home upto 12kw will remain powered till battery runs flat, PV comes or grid is restored.
