A different battery brand

Most of our battery jobs today are Sigenergy or GoodWe, but we install SolaX too, and this Ocean Shores home went with it: an X1-VAST 8 kW hybrid inverter and a T-BAT battery stack. New LONGi panels went on the white tile roof, and the existing solar was upgraded to hybrid operation so it works with the battery and keeps running in an outage.

Parts list

• Solar: 14 LONGi panels (475 W each), 6.65 kW, plus the existing solar upgraded
• Inverter: a SolaX X1-VAST 8 kW single-phase hybrid inverter
• Battery: a SolaX T-BAT HS21.6, about 21.6 kWh, on a besser block base
• Monitoring set up for the household

On a sloping block

The ground beside the house is uneven garden, so the battery stack stands on a level besser block base against the rendered wall, with the inverter mounted nearby under cover. On the roof, the panels went on in two blocks on the faces that clear the tall trees.

How every job like this runs

1. Free energy assessment from one or two recent power bills, or a quick phone call on 0483 903 020.

2. Custom design sized from the household’s real usage, with the federal Cheaper Home Batteries rebate and solar STCs taken off at point of sale. We handle the paperwork. See your rebates or try the battery rebate calculator.

3. Face-to-face site visit before install day: compliant battery position, switchboard and RCBO check, and agreement on what stays on in a blackout. No surprises on the day.

4. Install, usually one day, by our own electricians. No subcontractors. Then monitoring set-up, grid connection and a sign-off call.

Warranties

Every new install from us now comes with a 10-year battery warranty, 10-year inverter replacement, 25-year panel performance and our 25-year workmanship warranty on our installation work. Equipment is covered by the manufacturer warranties.

The federal battery rebate steps down on 1 January 2027 and again on 1 July 2027, based on install date. If a battery is on your list, it’s worth getting your assessment done early.

Questions we get asked

Do you install SolaX?

Yes. Alongside our main Sigenergy and GoodWe batteries, we install SolaX, Sungrow and Tesla. See SolaX batteries and GoodWe ESA vs SolaX.

Why a block base?

It lifts the battery stack off uneven ground onto a level, solid footing.

Can my old solar keep working in a blackout?

Here the existing solar was upgraded to hybrid operation so it works with the new battery and keeps producing in an outage. See does my solar work in a blackout.

How close to the beach can a battery go?

The makers set rules for salt air, and they differ by brand. Read solar batteries near the coast before choosing a spot.

Thinking about solar and a battery?

We’re based near Mullumbimby and install across the Northern Rivers. See solar and batteries in Ocean Shores and Brunswick Heads, or compare Sigenergy, GoodWe and Sungrow, Solax and Tesla.
