A free EV charger with your home battery? Compare the whole installed quote

The bonus belongs on the spreadsheet

Revcharge is offering a free EV charger with selected home batteries during November. That could be useful if both were already on your shopping list. It is also a good moment to remember that a bonus attached to a large purchase should earn its place on the spreadsheet. Free accessories have never paid an electricity bill by themselves.

What the November offer includes

Under Revcharge’s offer, eligible quotes must be accepted from 1 November to 11:59pm AEDT on 30 November 2026. Installation can happen later, although the company warns of longer lead times.

The pairings are myenergi libbi 2 with zappi GLO, Fox ESS CQ7 with Fox ESS A-Series, and Sungrow SBR or Sigenergy SigenStor with a choice of those chargers. Each included charger is 7kW single-phase. Sigenergy’s DC charging module is excluded, as are Powerwall 3 and charger-only purchases.

One charger and standard installation are supplied at the same property, during the battery visit. Switchboard upgrades, longer cable runs, trenching and three-phase work can cost extra and must be quoted before acceptance. There is no cash alternative or stacking with other Revcharge promotions.

The company’s battery service-area page currently names NSW, Victoria and South Australia. Confirm your postcode before assuming coverage, particularly outside metropolitan areas. This is not a verified nationwide battery offer.

Compare the finished system

Ask for an itemised total including GST, the exact battery and inverter models, usable storage, the charger and all electrical work. Then obtain another quote for a genuinely comparable system. Comparing a small battery with a much larger one tells you very little about the value of the free charger.

Usable capacity, measured in kilowatt-hours, tells you how much energy the battery can supply. Power output, measured in kilowatts, limits how much it can deliver at once. The government’s battery guide also makes clear that blackout support needs the right configuration. Ask which circuits are backed up, what extra hardware is required and whether your existing solar inverter can stay.

Warranty paperwork deserves the same attention. Check years, throughput or cycle limits, remaining-capacity guarantees and who handles labour and support locally. A handsome battery cabinet is not much comfort when the installer and manufacturer are pointing at each other.

The rebate has its own rules

The advertised battery prices already include the federal discount, so do not subtract it again. Eligibility is separate from the charger promotion. The Clean Energy Regulator requires an eligible battery connected to new or existing solar, approved equipment and an appropriately accredited installer.

Timing matters too. The regulator’s base rate falls from 6.8 certificates per usable kilowatt-hour in May–December 2026 to 5.7 in January–June 2027, with additional tapering for larger batteries. Accepting a November charger offer does not itself settle the eventual rebate calculation. Ask what happens to your fixed price if commissioning slips into 2027, and get the answer in writing.

Make the battery justify itself

Before signing, use your actual electricity bills and solar generation to test the savings estimate. Include when the car is usually at home, how much evening energy the household uses and the tariff you will pay. A household charging its EV during sunny hours has a different problem to one arriving home after dark.

My view: this is worth including in your quote comparison if you already need both products. Choose the battery system on its own merits first, then see whether the bundled charger improves the total. If the battery only becomes appealing because something else is free, put the calculator back on the table.
