Sunlight and solar panels.

Really need battery's and off grid capability whenever possible. Charger +Inverter or a hybrid. No Battery no power in the nighttime or a rainy day.

Problem with systems that need grid synchronization or cloud is you might have full battery's but still sit in darkness due to outages.

100% offgrid also really needs a generator of some kind to bridge longer bad weather periods.

@Kerplunk @nickofnz
You can have a grid tied system with battery backup that uses an Automatic Transfer Switch for off-grid use.

@Kerplunk @nickofnz

Depending on setup you'd need to switch from TN to TT earthing and possibly three phase to all using the same phase (for SMA Sunny Islands, at least). This complicates the ATS. Mine's single phase TT, so it's simpler.

@davep @Kerplunk @nickofnz
Yes. I have a single phase grid connected system with solar & a battery & backup of some circuits. The trick for ours is that those circuits always run through the inverter. In a grid outage I have power, internet & some power points.
Cloud in Melbourne today was grim, so I charged from the grid while the price was low - before 3pm.

@Kerplunk @nickofnz

Battery systems DC coupled to the inverter are by far the best option. They also need less complex management then AC coupled and you can normally mix vendors of inverters/batteries etc.

Thank you I will be looking in to a setup made from separate components.

My present Delta Pro with 2 extra battery packs is working fine but I am open to improvements at a reasonable price.

Looking at many non net connected setups I do not think I overpaid. Panels are in the garden btw.

@Kerplunk @nickofnz my Goodwe inverter has an automatic island mode which works from the BYD battery stack just fine. On a power outage it won't drive the full load of the house, but we can live without the dishwasher and air conditioner (we have large ceiling fans too). Came as a standard feature on the inverter, some messing about in the distribution board so that only the low power devices were powered, across the three available 3600W circuits for the island mode

Have about 15KW of solar panels, and about 15KWh in battery. So nothing fancy by Australian standards. The ducted aircon is a chunki boi pulling 4.5KW, so we were keen to drive that from the sun from morning to dusk on summer days
