Hi,

Could I add FOX ess 41.93kwh and H3 pro 15kw inverter and aiko 470 x 23 panels to the current sunpower max 6 with microinverters 10.6kw system.

Is that a possible? Will both system charge battery properly?

Thanks!

I'm not that familiar with the Sunpower system and micro inverters but typically micro inverters convert the DC from panels to AC for use in the house.

If the micro-inverters can all be connected together into a single AC feed so that the Fox system can monitor the amount of power being generated (you will need a second CT to be connected to that AC feed for this) then the Fox system will be able to calculate the amount of power being generated and charge / export etc.. with all available power.

If you don't connect CT2 the Fox system will be confused by the extra power generation and get it's load / export statistics wrong.

Which CT meter is available in Australia for that?

Apology for my technological ignorance.

Does that mean
-Sunpower max 6 Microinverters to CT meter, then to house, battery and grid
-Aiko panels to h3 pro 15kw inverter to battery, house and grid

Does the battery have two system connections like that?

Thanks!

This diagram is from the manual which explains the connections.

Your existing micro inverters should be connected where you can see 'METER2' i.e. you will have 1 or a number of phases coming in from the external micro-inverters and they would be connected via a second meter. This meter would be the same as Meter 1 ~ i.e. a Chint DTSU666 (either direct connected or using optional CT's)

It would measure the generated power from your other PV modules so that it can include it within the Fox metrics.

Where can I download the manual?

Can't find it in this

That's just for the battery itself, you need to be looking at the H3 Pro inverter manual https://www.fox-ess.com/download/upfile ... 250327.pdf

Thank you.
