The Inverter (the brain)
SolaX X1-VAST 5 / 6 / 8 / 10 kW · single phase
- Runs your house in a blackout, and switches over in under 10 milliseconds.
- On a single-phase home, Ergon allows 10 kVA in total for all inverters. We check your site.
- Up to 4 solar inputs for roofs facing different ways.
- Two battery ports, so there's room to grow.
Backup and the grid
Blackouts and the Ergon network
In a blackout. Both SolaX systems switch to battery in under 10 milliseconds. They can briefly deliver twice their rated power for 10 seconds, which helps start things like a fridge or a pump. What stays on depends on which circuits we back up, the inverter size, and how much charge is left. We'll explain what's realistic before you decide.
On Ergon. Ergon has to approve the system before we connect it, even if it won't send power to the grid. On a single-phase home, all inverters together can't go over 10 kVA, and export is usually capped at 5 kW per phase on a basic connection. Read more about solar and batteries on Ergon in Townsville.
Is it for you?
Is a SolaX battery right for your Townsville home?
A good fit if you
- want a slim battery that fits beside the car (15 cm deep blocks)
- like the inverter and battery in one tidy unit
- want your home to keep running in a blackout
- live in a single-phase home (most Townsville homes are)
- want to start smaller and add blocks later
Talk to us first if you
- have a three-phase home. The SolaX models we install are single phase, so we'll show you options from our other brands too.
- already have a SolaX solar-only inverter (like an X1-BOOST). Read about adding a battery to existing solar. We’ll check whether your setup needs a new hybrid inverter.

01Do you install SolaX batteries in Townsville?
Barra Solar Power does. Our own licensed electricians design, install and support SolaX battery systems in Townsville and across North Queensland. Call 07 4401 5122 or request a quote online.
02How big a SolaX battery do I need?
It depends on how much power you use after the sun goes down. We size it from your power bill and how you live. The slimline goes from 5.1 to 20.4 kWh. The standard battery starts at 7.3 kWh (2 blocks) and grows one block at a time.
03Can I add more battery later?
Yes, within limits. The slimline takes 1 to 4 blocks (up to 20.4 kWh). On the standard battery, each X1-VAST battery port takes 2 to 8 blocks, and there are two ports. If you think you'll use more power later, for example with an EV or a pool, we'll plan for it in the first design.
04Will a SolaX battery keep my power on in a blackout?
It can. Both systems switch to battery in under 10 milliseconds. What stays on depends on which circuits are backed up, the inverter size, and how much charge is in the battery at the time. We'll explain what's realistic for your home before you decide.
05What's the difference between the slimline and the standard battery?
The slimline (X1-IES) has the inverter and battery in one, with blocks only 15 cm deep, up to 20.4 kWh. The standard battery (T-BAT HS) is a floor-standing tower that pairs with a separate X1-VAST inverter (5 to 10 kW), and it can grow bigger.
06Will it work on the Ergon Energy network?
Yes. Ergon must approve it before we connect it, even if it won't export. On a single-phase home, the inverters count toward Ergon's 10 kVA limit, and export is usually capped at 5 kW per phase on a basic connection. Read more about solar and batteries on Ergon in Townsville.
07What warranty do I get?
SolaX gives 10 years on the X1-IES, X1-VAST and T-BAT HS batteries under its Australian warranty terms. On top of that, we give our own 10-year workmanship warranty.
