About SolaX Power

High-voltage storage from an established inverter brand

SolaX Power designs hybrid inverters and high-voltage battery storage, with a modular Triple Power battery range that scales to suit a wide span of Australian homes.

SolaX Power focuses on hybrid solar inverters and high-voltage battery storage. Its Triple Power battery range is modular and stackable, designed to support different household capacities, power requirements and levels of energy independence.

  • Modular high-voltage storage

    Stackable 5.1 kWh LFP modules let households size storage from around 10 kWh to 66 kWh and expand later.

  • Inverter-led ecosystem

    A long heritage in hybrid inverters means the battery is designed to work as part of a coordinated solar-and-storage system.

  • Safety and monitoring

    LFP chemistry, an IP66 enclosure, aerosol fire suppression and remote monitoring support safe, serviceable operation.

In Sunbridge’s eyes

An inverter heavyweight that grew into storage

SolaX Power is one of the more established names on this list — a Chinese manufacturer that has been building grid-tied and hybrid inverters since the early 2010s and is a familiar sight on Australian roofs and switchboards. Its Triple Power high-voltage battery range extends that inverter heritage into storage: a stackable LFP tower that scales from 10.2 kWh to 66.5 kWh at a full 100% depth of discharge, with an aerosol fire-suppression module built in.

  • Genuinely modular — stack 5.1 kWh LFP modules to 51.2 kWh in one tower, up to 66.5 kWh across two.
  • Full 100% depth of discharge and more than 6,000 cycles rated at 100% DoD.
  • Layered safety — LFP cells, IP66 enclosure and a built-in aerosol fire-suppression module.
  • Backed by a long inverter track record and broad installer familiarity in Australia.
Best suited to

homes wanting scalable high-voltage storage from an established inverter brand — most at home paired with SolaX or compatible solar, so the battery and inverter are designed to work together.

The right fit for your home — and fully backed

Why the SolaX Triple Power TSYS-HS51 fits your home

Homes wanting room to grow

A stackable high-voltage tower that scales from 10.2 kWh to 66.5 kWh in 5.1 kWh steps, so you can size for today and add modules later.

Every kWh you pay for

A full 100% depth of discharge means the rated capacity is the usable capacity — no reserve is held back.

Safety-first outdoor installs

An IP66 enclosure with a built-in aerosol fire-suppression module targets protection at the source, so it can be installed outdoors with confidence.

High-voltage efficiency

A high-voltage architecture keeps current low for the same power, supporting strong charge and discharge with lower losses.

Warranty & compliance
  • The SolaX Triple Power TSYS-HS51 uses LFP cells rated for more than 6,000 cycles at a full 100% depth of discharge, tested to the standards listed on the datasheet, and carries an IP66 enclosure for outdoor installation.
  • SolaX’s manufacturer product warranty applies to the battery, and your guarantees under the Australian Consumer Law apply in addition. Warranty terms can depend on the configuration and registration; Sunbridge confirms the current terms for your setup and registers the warranty on your behalf as part of the installation.
Rebates & payback guidance
  • Home battery storage can be eligible for government rebates and incentives, which change over time and vary by state and household. A correctly sized TSYS-HS51 system — paired with the right rebate — can meaningfully shorten your payback period.
  • Sunbridge handles rebate guidance as part of the quote process: we check current eligibility, factor available incentives into your system design, and show you the expected payback based on your actual usage. See our battery rebate guidance for more, and we will confirm what applies to your address when you request a quote.
