The Perfect Starting Point for Your Tiny House or Granny Flat.
If you're building a tiny house, setting up a granny flat off-grid, or want a clean compact system for a small weekender — this is where to start.
The 48V 6000VA Budget Kit is built around the Victron Multi RS Solar — an all-in-one inverter, battery charger and MPPT solar controller in a single unit. Less boxes on the wall, less wiring, same gold-standard Victron reliability. It's a smart, tidy system that punches well above its weight for the price.
🎁 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 / Charger / Solar MPPT (All-in-One)
- 1x Victron Multi RS Solar 48/6000/100-450/100
This is the clever part. The Multi RS Solar combines a 6000VA inverter, a battery charger and a dual-tracker MPPT solar controller all in one unit. That means fewer components, simpler wiring and less to go wrong. It delivers grid-quality 230V power from your batteries, charges from a generator or shore power automatically, and manages your solar input — all from a single box. Victron's best value all-in-one for off-grid systems.
Solar Input
The built-in MPPT 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 the one unit. Run panels on two separate roof faces or orientations without needing a second controller.
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.
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.
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
- 2x BSL 48V 5.12kWh Rack Mount LiFePO4 Battery (10.24kWh total)
Lithium iron phosphate — the safe chemistry. No thermal runaway, long cycle life, and rack-mounted so they look tidy in any install. 10.24kWh is what I consider a great starting point for a tiny house or granny flat — enough to get comfortably through a night 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.
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 tiny house or granny flat on this system would comfortably run:
- Split system air conditioner (2–2.5kW)
- 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.
