My solar system is in the shed with the panels on the roof. It's a 6kW Huawei inverter and with 6.6kW of panels it does regularly hit 6.0 at the inverter. It's only connected back to the house with a 6mm2 cable, so not sure if that would support 8kW... Looks like a hefty price increase from 6 -> 8kW in the inverter price, and not sure I would benefit much from more than 6kW - I'm not planning on going offgrid.

A typical summer day of usage (excluding overnight EV charging at 8kW) looks like this.

I had been waiting for a legal way to buy a Leaf and plug it into an inverter but I think that's a way off (legally) :-(

The connection back to your house will likely be the AC output from the inverter, so irrelevant to the battery. You’d need to place the battery as close to the inverter as possible and run say, < 1m length 50mm2 cable for each positive and negative cable to the inverter.

Based on that graph it does appear that your inverter is clipping to 6kW for a couple hours during peak sunshine hours, so you’d be losing a small bit of kWh when it’s really sunny. But it’s not uncommon to oversize PV to inverter size, often by 20-30% due to PV usually operating at 75-80% of there rated output (and better for winter months)

If you have roof real estate to add another string of PV panels, then going 8kW Deye and battery would be even more appealing to be honest.

I will add though, it obviously depends on 1. What you’re wanting to achieve and 2. what your budget is, unless 3. You’re just environmentally conscious and/or 4. Want to stick it to the power companies :-)

Dropped to $4k + GST per unit ($4600) to move these last 2 units quickly, can't go lower than that

Your inverter must support low voltage DC (52VDC)

Thanks to those who have already enquiried, it's unfortunate your inverters DC voltage doesn't match up. To see if yours does, search the datasheet of your inverter and check under the battery section that the voltage (or voltage range) is within the Basengreen 52VDC voltage, if it's outside that range it won't work.

For example, Deye 8kW hybrid will work:
