Hybrid inverters can connect solar panels AND a battery.

All hybrid prices below include the inverter's consumption meter.
All inverters include a WIFI dongle.
MPPTs refers to how many separate strings of solar panels can be connected.
Oversize refers to the maximum kW of panels that can be connected with a battery.
Without a battery the maximum oversize is 6.66kW
No installation costs are included.

Brands
Growatt are the only 'cheaper' brand we consider good enough to supply and install.
Growatt's new ALP and APX batteries are parallel connected with optimisers which is impressive.
Their 10kW and 15kW 3 phase inverters 3 x MPPT inverters with parallel strings on all is also excellent.
Whilst I am saying they are worthy, please don't mistake that for whole-hearted endorsement.
They ARE a budget brand and quality is not quite up there with some of the others.

Goodwe and Sungrow are very similar in terms of design and features.
Backup circuitry is built into all the inverters which is both a good and bad thing.
Unoptimised, Series connected batteries makes them a bit less attractive.

Sigenergy and iStore are the brands that most people ask us for and with good reason.
Top quality, highly featured.
Optimised, parallel connected batteries with fire extinguishers.

Fronius and SMA are the two European brands.
We are waiting to see how SMA's new hybrid inverter and battery performs.
Fronius have their own battery coming soon which may make it more appealing than the BYD battery currently used.

What a difference a year makes.
This time last year no battery rebates. No sign we were ever going to see any in WA.
Fronius ruled the roost with Sungrow pecking away at their market share.
Now Sigenergy dominate which is simply extraordinary for a new brand.
iStore's new product range has done very well too over the past year too.
