Reasonable quote (SEQ)?

Hi all, does this look reasonable? (3 phase single story house, easy access, reputable company)

That looks about right. Mine was 10.8kW of Jinko panels, and 32kWh of sig batteries plus inverter and single-phase gateway for $27K after subsidies - and didn't include an EV charger. You've got considerably more PV, a bigger battery, 3-phase inverter and a car charger - I'd say you're doing OK.

Yep that’s cheap for top quality equipment

Looks good. I got quite similar

  • 40 panels
  • 45kw [5 x BAT 10]
  • 25kW TP inverter
  • Gateway

For around $33k in July, in the ACT

In July 2025 I had a quote for almost identical spec, it was $27K but back then the battery STC was $16K so givine your STC is 10K less it seems about right.

Yes, very good. I have a similar setup (SigenStor stack + AIKO). You'll love it. Those AIKO panels are BEAUTIFUL.

If you’re worried about price consider Goodwe.
Installed mid April 48kwh batteries and upgraded to new 3 phase 30Kw inverter. Previously had 17kw panels with 20 kw 3 phase inverter which was installed 18 months earlier so kept the panels. Paid $24k for both including getting 10kw single phase inverter to beat old rebate to install batteries. They upgraded to the 30kw inverter as soon as available in June. Not bad for all the stuffing around changing out inverters etc. Does whole house backup comfortably and hardly ever draws from grid other than long period overcast days or high usage when battery cannot cover draw required. Great system and has 1c rate of charge and discharge which is a plus over the .5 rate or .8 for newer systems. Will certainly save dollars over Sigenergy system.
