Hello everyone,
Not really sure where to start, but here it goes, basically embarking on a diy battery system/install here in Western Australia. This is still in the planning phase, I have yet to purchase anything substantial for the battery system yet, nor have I got any approvals, apologies for the lackluster drawing,
The solar is already done.
What I do have;
19kW of solar tied to a 15kW Fronius inverter (roughly about 7years old).
Fronius smart meter installed.
3phase subboard where the intended batteries are going.
3phase EV Charger in the garage
A very good sparky :$
What I'm planning,
3x Goodwe GW5000s-BT as I believe are GRID approved in Australia,
5-10kWh 48V batteries on each inverter.

Questions I have;
1. Anybody in Western Australia know how hard this would be to get approved?
2. How does the Fronius and Goodwe inverters play nicely together? I.e. How does the goodwe know to charge the batteries when there's excess solar but also be able to charge the batteries from the grid in the "Super Off Peak" tariff.
3. Pretty similar to the 2nd question, How does the HOUSE know to use the excess solar rather than the batteries
I'm sure these are pretty straight forward questions, and I'm likely to have more. I just thought I'd get the ball rolling and add more questions as they come up.
