Inverters

SolaX hybrid inverters

The inverter runs the whole system. A hybrid takes power from your panels, your battery and the grid, and decides where it goes from moment to moment.

Which one suits your home

X1-Hybrid G4 5.0-D

Most single-phase homes

Output

4,999 W

Panels, up to

10 kWp

Backup

5,000 VA, 7,500 VA for 10 s

Weather rating

IP65

Backup covers a few chosen circuits, like the fridge, lights and power points.

X1-VAST-10K

Whole-home backup on single phase

Output

9,999 W

Panels, up to

20 kWp

Backup

9,999 VA, double for 10 s

Weather rating

IP66

SolaX lists whole-home backup as a supported mode, and the extra surge helps start motors. It also has two battery ports and four panel inputs.

X3-Hybrid G4 5, 10 and 15 kW

Three-phase homes

Output

4,999, 9,999 or 14,999 W

Panels, up to

10, 20 or 30 kWp

Backup

5, 10 or 15 kVA, at most 5 kW per phase

Weather rating

IP65

Backup runs as three separate phases, so we plan which circuits sit on each one.

What a bigger inverter does and doesn't do

Synergy's DEBS buyback pays on up to 5 kW of exports whatever the inverter size, so a 10 kW inverter earns no more buyback than a 5 kW one. The reasons to go bigger are whole-home backup, more panels, and large daytime loads such as ducted air conditioning, a pool or EV charging.

Keep it on your Wi-Fi

Every new system in WA starts limited to 1.5 kW of exports. Synergy raises that limit remotely after commissioning, which needs a working internet connection at the inverter, and the 1.5 kW limit comes back if the connection drops. We check the Wi-Fi signal at the inverter position during the site visit.

Monitoring and the future

You can watch solar, battery and home use live in the SolaX Cloud app. All three models are also VPP ready, so they can join a virtual power plant later if you choose to.
