Power Command Hub
Building your dream off-grid setup & want the government to help pay for it?
When you are moving past basic camp lighting and stepping up to a serious off-grid power system for a remote shed, a high-end caravan, or a bush cabin, a basic servo inverter just won't cut it. Getting the government to pay for your heavy-duty battery bank is only half the battle; you need an intelligent brain that can actually handle massive 240V loads without frying your entire setup.
The Heavy-Duty Hybrid Solar Inverter replaces thousands of dollars worth of separate electrical components and is fully compatible with subsidized battery builds. Available in a 4.2kW (24V) or an extreme 6.2kW (48V) model, it combines a pure sine wave inverter, a massive 120A MPPT solar controller, and an AC battery charger into one bulletproof unit. Boasting a huge 500VDC solar input, smart load-shedding dual outputs, and the ability to run 240V gear directly from your solar panels without a battery connected, it is the ultimate heavy-duty hub for your off-grid build.
If you want to claim the 2026 battery rebate, you need reliable gear to run it all.
- Maximise Your Gov Rebate: Using the Federal Battery Rebate for a massive 48V bank? Don't bottleneck it with cheap gear. This is the premium, high-efficiency brain your subsidized setup demands.
- Run Without Batteries: Looking to power a workshop just during the day? This unit can bypass batteries entirely and run your 240V power tools straight from the solar array.
- Smart Load Shedding (Dual Output): Wire your fridge to the primary output and your heavy tools to the secondary. Set the inverter to automatically kill power to the tools when the battery drops to 50%, ensuring your beer stays cold and your food doesn't spoil.
- Save Money on Wiring: The massive 60-500VDC solar input range means you can wire your solar panels in series. This keeps the amps low, meaning you can use thinner, cheaper solar cable from the roof to the inverter.
- Survive the Storms: Fully integrated AC/PV air circuit breakers and a built-in lightning arrester stop nasty power surges and outback lightning strikes from blowing up your expensive gear.
-
Revive Dead Lithium: Features built-in automatic lithium battery activation to safely wake up and recharge deep-cycle lithium batteries that have tripped their internal BMS (Battery Management System).
- Survive Outback Storms: Fully integrated AC/PV air circuit breakers and a built-in lightning arrester stop nasty power surges and lightning strikes from blowing up your expensive gear.
- Ditch the Battery Entirely: Looking to power a workshop just during the day? This unit can bypass batteries entirely and run your 240V power tools straight from the solar array.
Key Features
- Massive 120A MPPT Controller: Harvests maximum power from the sun, supporting a huge solar array on your roof (up to 6200W for the 4.2kW, and 6500W for the 6.2kW).
- On-Grid / Off-Grid Versatility: Use it entirely off-grid in the bush, or hook it up to the mains at home to slash your power bill by prioritising solar usage.
- WiFi & BMS Dual Communication: Connect your smartphone via iOS or Android to monitor your exact solar input, battery health, and power draw from the comfort of the campfire.
- Save Money on Copper: The massive 60V-500VDC solar input range means you can wire your panels in series, keeping the amps low so you can use thinner, cheaper solar cable.
- Harsh Environment Ready: Ships with a built-in anti-dust kit to keep out the brutal outback red dirt and workshop sawdust.

Specs
BushLine Pro Tip (Start-Up Sequence): To ensure maximum stability and prevent massive inrush currents from tripping your gear, always follow this start-up sequence:
- Turn on the Battery switch.
- Turn on the AC/PV input.
- Turn on the Load.
- Reverse this exact process when shutting the system down!
