Stop guessing which panels pair with which inverter. Voltz Energy pre-engineers complete matched solar arrays and high-capacity battery storage banks, fully installed with bi-directional smart metering, safety switches, and government rebate deductions.
440W bifacial high-density modules capture direct peak sunlight and ambient diffuse sky radiation with 22.8% cell efficiency.
Direct DC-to-DC battery charging (>98.2% round-trip efficiency) bypasses duplicate inverters and eliminates wall clutter.
Garage-mounted cobalt-free lithium storage with 10,000+ cycle lifespan, active thermal cooling, and 100% usable capacity.
Your 10kW rooftop array generates 8.2kW. Household appliances consume 1.8kW (air con, fridge, laundry). The remaining 6.4kW flows into your 28kWh battery at maximum charging velocity. Zero electricity is purchased from the grid.
When the street grid drops out, the integrated ATS switch forms an immediate microgrid keeping refrigeration, lighting, and Wi-Fi alive.
Cleanly energizes living zones, bedroom lighting, induction cooking, and climate heat pumps with bi-directional phase safety.
Federal STCs combined with state battery schemes (VIC VEU, NSW PDRS, QLD Booster) deducted point-of-sale in a single transaction.

Direct DC-to-DC battery charging (>98% round-trip efficiency) eliminates duplicate inverter hardware and reduces wall-space footprint.
One-day simultaneous commissioning of roof racking, panels, battery bank, and main switchboard backup isolation by certified CEC electricians.
Federal STC discounts combined with state battery loans and battery incentives deducted upfront on a single final invoice.
Installing rooftop solar and high-capacity battery storage together eliminates thousands of dollars in redundant hardware, duplicate tradesman labor, and split rebate administration.
When buying solar first and retrofitting a battery later, you end up purchasing two separate inverters: a standard solar string inverter, plus an expensive AC-coupled battery inverter with duplicate conversion losses.
Two separate installations mean double scaffolding, double roof-work safety setups, and two separate electrician callouts. A turnkey combo wires everything simultaneously in a single day.
Bundling unlocks simultaneous point-of-sale deduction of Federal STC discounts alongside state-specific storage incentives (VIC VEU / WA DEBS / NSW PDRS / QLD Battery Booster) calculated and deducted in one transaction.
Third-party retrofits often struggle with proprietary communication protocols, resulting in phantom standby drain and delayed blackout response. Our combo units communicate natively via high-speed CAN bus.
