Built for the Shouse. Sorted for the Weekender.
If you're building a shed house, finishing off a weekender, or setting up a small off-grid home and you want a proper system — not a cobbled-together mess — this is the kit.
The 48V 8000VA Budget Kit is the most popular system we build. It's powerful enough to run your aircon, fridge, lights, TV, and everyday appliances without sweating it. And it's built around gear that actually lasts.
🎁 Every kit includes 3 x free 30-minute phone calls with Landon — a licensed sparky who designed this system. Use them to plan your install, troubleshoot on the day, or get your Victron app set up properly. You're not buying a box of parts and getting left to figure it out yourself.
What's in the Kit
Inverter
- 1x Victron MultiPlus-II 48/8000/110-100 230V
The heart of the system. 8000VA of continuous power with a built-in charger — so if you've got a generator as backup, it handles the switching automatically. Victron is the gold standard in off-grid. There's a reason everyone uses it.
Monitoring
- 1x Cerbo GX MK2
- 1x GX Touch 70 Display
- 1x VE.Direct Cable 0.9m
- 1x 2m UTP CAT5 Cable
- 1x VE.Can to CAN-bus BMS Type B Cable 1.8m
Keep an eye on your system from your phone, tablet, or the wall-mounted display. The Cerbo GX connects to Victron's free VRM portal so you can monitor from anywhere — great if the property isn't your primary residence.
Solar Charger
- 1x SmartSolar MPPT RS 450/100-Tr
- 1x 4 Pole DC Distribution Centre
- 2x Noark MCB 25A 360VDC 2 Pole
The SmartSolar MPPT RS 450/100-Tr features 2 independent solar trackers, each capable of handling up to 4000W of solar input — giving you a total solar capacity of up to 8000W from a single controller. This means you can run two separate string configurations (different orientations, different roof faces) without needing a second MPPT unit.
Solar panels are sold separately — check out our range of fixed solar panels here and get in touch if you need help sizing your array for this kit.
Distribution & Fusing
- 1x Noark MCCB 160A 500VDC 2 Pole
AC Distribution
- 1x 8 Pole AC Distribution Board
- 1x 32A Double Pole AC Circuit Breaker
- 1x 20A Double Pole AC Circuit Breaker
Batteries
- 3x BSL 48V 5.12kWh Rack Mount LiFePO4 Battery (15.36kWh total)
Lithium iron phosphate — the safe chemistry. No thermal runaway, long cycle life, and rack-mounted so they look tidy in any install. 15.36kWh is what I consider a great starting point for a shouse or weekender — enough to get through a night comfortably without solar input.
The best part? The battery bank is fully scalable. As your energy needs grow, you can simply add more BSL batteries to the rack at any time. No need to replace the inverter or rewire the system — just plug in and expand. It's one of the reasons I spec this setup as a starting point rather than a ceiling.
Cables & Lugs
Everything you need to wire the DC side of the system:
- 2m of 6mm² 2Core+Earth 240V Cable
- 2m of 4mm² 2Core+Earth 240V Cable
- 3m of High Quality 50mm² DC Flex Cable
- 8m of 6mm² Earth Cable
- 1x Pack 50mm² Lugs with 8mm Hole (10 pieces)
- 1x Pack 6mm² Lugs with 6mm Hole (10 pieces)
- 1x Pack Bootlace Pins 6mm² (10 pieces)
Wiring Diagram
A professional wiring diagram is included with this kit. It's been purpose-built for this exact system so you know precisely how everything connects together — no guesswork, no Googling. Whether you're handing it to your sparky or working through the install yourself, it makes the whole job a lot smoother.
What Can It Run?
A typical shouse or weekender on this system would comfortably run:
- Split system air conditioner (2–3.5kW)
- Fridge/freezer
- Lighting throughout
- TV and entertainment
- Laptop, phone charging, small appliances
- Washing machine (occasional use)
Note: This kit does not include solar panels or solar mounting hardware. It also does not include AC wiring beyond the distribution board — your sparky will handle that on-site.
Is This a DIY Kit?
Yes — everything here is designed to be installed by a competent DIYer or licensed electrician. The DC side (batteries, inverter, MPPT) can be self-installed. The AC connections must be done by a licensed electrician to comply with Australian standards.
