Cost of living pressure is real, and electricity is one of the few household bills that keeps climbing. Victoria's minimum feed-in tariff is low, so exporting your solar for a few cents a kilowatt-hour is worth far less than storing it and using it yourself after dark.
A well-sized battery lets you shift the solar you're already generating into the evening — when your household actually uses most of its power — instead of selling it back to the grid for next to nothing. That's real money back in your pocket, every single day.
Your battery is imported and supported by a local entity based in Cheltenham, Victoria — ready to provide direct customer support, not just an overseas marketplace listing.
A large-format home battery built around CATL's automotive-grade LFP cells — the same cell family trusted by major EV makers — paired with a compact, whisper-quiet hybrid inverter designed and rated for Australian conditions.
Mercy Rays installs the Mango Power M AU as a massive 28.6kWh system — two 14.3kWh modules on one 6kW hybrid inverter — sized to genuinely take a big bite out of your daily electricity costs, not just top up a small buffer.
