Agree on this. I am over-panelled, but on a few consecutive overcast days it's still a close-run thing.

At my office I have a standby 6.5kW silent diesel genny on the ATS output from the Deye, at home I have a 'spare' 4kW of panels on their own Kodak invertor which I switch in to help charge (I also have a standby genny, but it hasn't been used in a year).

I am doing a major extension project at my office right now and will put up 4 more strings of panels and a second Deye 8kW (paralleled) when I have finished. Power is like beer or ammunition. You simply can never have too much.

Hi Pooky it looks like a healthy budget that you have, plan looks good. Just to check are you planning on feeding in to the grid? Does your municipality allow that?
 
If not I'm not sure what added benefit that you won't get form 2 Axpert max 8kw? With 60kw storage. Maybe a dedicated generator input?
I actually do want to feed into the grid and plan on upgrading to an inverter that supports it as soon as my municipality sorts it out. 

Hi Pooks, 
It sounds like our consumption if very similar. 
I am running 1 x 8kw Sunsynk inverter with 28 x 455 Watt panels in an East West split with & 2 x 6kw/hr BSL Batts
My monthly winter power consumption maxed out in July @ 1650kw/hr's  of which I purchased 660kw/hr from City power and generated 1060kw/hr myself (this was with 24 panels prior to upgrading to 28 panels)
This month I am on 1510kw/hr of which I have produced 1290kw/hr myself and used 279kw/hr from City Power. 
My experience is that the main thing is to schedule all your heavy loads to daylight hours and minimise your parasitic loads at night. 
Having an East/West Split with my panels definitely helps as it gives me a much wider spread of power during the day.
2 x 8kw Inverters & more batteries would definitely help as my inverter runs quite hard during the day, my max daily production is 56kw but my batteries are usually fully charged by 13:00 so there is usually quite a bit of power available with no where to go. I decided to go with extra panels so as to get me fully charged on the marginal days.
