Green Bank Solar builds complete off-grid solar power systems for Australian homes, farms, sheds, rural blocks and factories. Every system pairs a Green Bank or Deye inverter with our own LiFePO4 lithium batteries in a pre-wired, plug-and-play cabinet — delivered ready to connect, from our Melbourne warehouse to anywhere in Australia.
We've been in solar since 2012 and manufacturing our own lithium batteries since 2019. Our systems run everything from tiny houses to a university campus in Vanuatu housing 200 students, and our battery banks scale to 16 × 30kWh — 480kWh from a single installation, the largest lithium bank we offer in Australia.
Send us your appliance list or your current power bill and our Australian team will size the system, quote delivery to your address, and tell you honestly which package fits. Fast, straight answers — see our Google reviews.
Pick your size
Start from how much power you use in a day and how big your largest loads are. These are our most popular pre-wired packages — all expandable later.

Prices are for the pre-wired cabinet with inverter and battery, excluding delivery. Solar panels, rail kit and freight to your address are quoted on top — see below. Need more capacity? Every system takes additional batteries in parallel.
What's in a Green Bank package
- Pre-wired cabinet — inverter and battery mounted, cabled and tested before it leaves us. Connect your panels, your loads and a generator input and you're running.
- LiFePO4 lithium battery — our own Green Bank batteries, 8,000-cycle CATL cells, compatible with 16+ inverter brands if you ever change inverter.
- Off-grid or hybrid inverter — Green Bank MITS series or Deye, single or 3-phase, with generator auto-start.
- Solar panels (optional) — Trina 475W panels; most off-grid systems use 14–22 panels depending on inverter.
- Rail kit (with panel packages) — rails and extenders, brackets, mid and end clamps, earthing clips, DC isolators, MC4 and Y connectors, and 30m of 4mm PV cable.
Prefer to build it yourself? We also sell items-only packages — the same inverter, battery and panels without the pre-wired cabinet, for installers and experienced owners.
How to size an off-grid system
Three numbers decide it:
- Daily energy (kWh) — add up what you use in a day. A typical household is 10–20kWh. Your battery should cover at least one full day without sun.
- Peak load (kW) — the biggest thing you'll run at once. Air conditioners, pumps and welders decide your inverter size, not your daily total.
- Solar array (kW) — enough panels to refill the battery on a winter day. Rule of thumb for most of Australia: panel kW roughly equal to daily kWh divided by three, so 15kWh a day wants about 5–7kW of panels, and more the further south you are.
If that's more maths than you want, send us your appliance list and we'll do it for you — no obligation.
Supply only, or installed?
Most customers buy supply-only: the cabinet is plug-and-play and needs minimal installation, and a local electrician or solar installer mounts the panels and makes the final connections. We also install directly across the metro areas of Melbourne, Sydney, Brisbane, Adelaide and Perth, and in regional areas we service including Lightning Ridge and Bundaberg. Ask us whether your location is covered.
Delivery and warranty
Systems ship on a pallet from our Truganina, Victoria warehouse to anywhere in Australia, with freight quoted per order based on your location. Pick-up is welcome. The GB48200 and GB48300 batteries carry a 10-year warranty; ask us for the warranty terms on other models, and support comes from our own Australian team — call or email and you'll get an answer from someone who knows the system.
Off-grid solar: common questions
How much does an off-grid solar system cost in Australia?
It depends on your daily usage, peak loads, panels and location. Our pre-wired packages start at $9,999 for inverter and battery (plus delivery), and complete installed systems range from around $10,000 for a small weekender to $120,000 for a large farm or commercial site.
How many solar panels do I need?
Most off-grid homes use 14–22 × 475W panels (6.6–10.5kW). Each inverter has a maximum PV input, so the ceiling depends on the inverter you choose — we'll tell you the limit for your system.
Can I add to the system later?
Yes. Batteries connect in parallel, and panels can be added up to the inverter's PV limit. Many customers start with one battery and add a second within a year or two.
Does it work in winter?
Yes. Winter days produce less solar, so the system is sized with a margin and a generator fills the gap on long cloudy stretches. The inverter can auto-start the generator when the battery gets low.
Do I need a generator?
Every off-grid system must have a generator backup. It may run only a few hours a year, but it's what gets you through a week of rain or a fault without losing power.
Or email contact@greenbanks.com.au with your location and what you need to run. We'll come back with the right package and a delivered price.
