Crunch my numbers

Hi. I'm trying to figure out if I'm onto a good thing here or not with my energy plan. I'm hoping someone can crunch the numbers to see if I can do better with another provider

I had a 36kw Sigenergy battery with a 15kwh 3 phase inverter installed 2 weeks ago. I've got about 16kw of panels on the roof. I'm in self consumption mode on the Sig app.

My energy retailer (Engie) pays me a 12 cent FIT all day. The daily supply charge is $2.17 and the flat rate is $0.47 per kWh. There is no TOU tariff just a flat rate.

In 14 days I've only imported 4.78 kw from the grid and exported 312.39 kw

I know the DSC and flat rate are high but getting 12c FIT all day is pretty decent.

AC coupling with existing Enphase micro inverter array

I've just put a deposit on adding a 36kwh Sigenergy battery, 3 phase 15 kwh inverter and Gateway with full backup. I'm adding 12kw of new Jinko panels to an existing 5kw array with Enphase IQ7 micro inverters.

Once it's AC coupled is there any need to keep the Enphase Envoy Gateway and all the monitoring wiring cluttering the back of the meter board?

Won't the Sigenergy app make the Enphase Envoy and monitoring app redundant?

Btw. The System price was $22,990 including NSW home owners compensation insurance

How's this quote?

Sigenergy 36kw battery with a 15kw 3 phase inverter plus backup gateway and additional 3.8kw of Jinko 475w solar panels (adding to existing 8kw of arrays)

$21,490 installed.

The above with a 27kw battery is $17,990

Does anyone know why this is occurring. Half the leaves have this type of discolouration. It was like this when I got it 12 months ago and I thought it would grow out of it. I've been hitting it with diluted composted cow and chicken manure tea to try to get it to green up.
