Makes sense, it comes down to how much of that 42 kWh you’re actually cycling each day. Once you switch to reverse cycle, utilisation…

A 10-13 kWh battery will cover your nights and still cycle daily, which is what will drive your ROI. The 40+ kWh system won’t get…

Do you run the aircon all night, or just a few hours in the evening?

With 2 houses on one system and future EV/café load, 3-phase makes sense. The 3-phase is about handling higher loads and spreading them…

Victron SmartSolar MPPT is what you want, the 100V models suit your setup. Size the MPPT to your array. Avoid cheap no-name MPPTs, they…

A 42 kWh battery stores 42 kWh, so it can supply up to 42 kWh per day if fully charged. In your case, you’re only using 4 kWh overnight,…

You only need around a 5-8 kWh battery. That will cover your night usage. Anything larger will be underutilised and won’t pay back…

A 48 kWh battery only makes sense if you’ve got high overnight usage or want grid independence. What are you actually trying to run…

ROI is definitely part of it, but that calculation only makes sense if the battery actually cycles daily and offsets real imports. With…

Check the DC/AC ratio: 40 kW of panels on a 30 kW inverter is common, but you should understand expected clipping and whether export limits…

Nominal vs. usable capacity makes a big difference. 40-50 kWh installed typically sits far above those figures, even after rebates. I’d…

For two people with a $120 bill, 40 kWh battery is very large. The 9.4 kW solar makes sense. The 40 kWh battery is likely oversized unless…

It is a late reply, but I hope you got the 10kW With ducted AC and a future EV, 6.6 kW will not be enough in no time. You have a…

You’re essentially drawing from the grid when it’s cheap and using it later when it’s expensive. This will work if the tariff…

The price you should be targeting is around $10k if it includes gateway, meters, commissioning, and compliance in North Queensland.…

Noted on this. EV charging overnight with 2-3 aircons running will take your night usage to 25-40kWh. You already have 14kW of PV, which is…

Bigger isn’t always better (unless you have high night usage). Go back to basics. What is your actual nighttime vs. daily usage? Your…

What’s your actual nighttime usage? 42 kWh is a big battery tank unless you have high night usage or want strong blackout autonomy. With…

Do you need a 50kWh battery? The battery should be quoted from night time usage or else most of your battery will sit idle most days…

What's your actual night usage now? And how much of that will you be running from the pool? The size of the battery should be based on…
