24V Off-Grid Power Kit ideal for Motorhomes, Large Caravans, or Yachts

This 24V off-grid power kit is built for motorhomes, large caravans, yachts, and full-time off-grid setups that require consistent and high-output energy. It runs fridges, lights, and essential appliances daily without relying on grid power. Designed for Australian conditions, it delivers stable performance for both mobile travel and remote living.

If you're travelling full-time, living off-grid, or exploring the open sea, our 24V Mobile Off-Grid Kit is built for serious energy demands and long-term independence. This complete solution is perfect for motorhomes, large caravans, yachts, houseboats, or tiny homes

At the heart of the system is a high-output 5kW 24V low-frequency pure sine wave hybrid inverter with a built-in 60A MPPT solar charge controller. Whether you're powering air fryers, washing machines, laptops, or even small air conditioners, this inverter handles it all — and automatically switches between solar, battery, generator, or mains input for uninterrupted operation.

The kit includes 4 x 440W Jinko Solar Panels (1760W total), providing fast solar charging even in shaded or low-light conditions. You’ll also receive a 24V LiFePO4 Battery Kit (100Ah–280Ah) made with genuine EVE cells, housed in a durable 24V case and managed by a JK SMART BMS with Bluetooth for real-time monitoring.

To keep you powered while driving or cruising, a powerful 24V 50A DC-DC charger is included — ideal for alternator charging from your tow vehicle or vessel engine.

Whether you’re exploring remote locations or living off-grid year-round, this 24V system delivers powerful, clean, and efficient energy — ready for wherever you roam.

The system includes:

  • 4 x 440W Jinko Solar Panels for efficient charging
  • 24V LiFePO4 Battery Kit (100Ah–280Ah) with JK SMART BMS
  • Bluetooth monitoring for real-time performance tracking
  • 24V 50A DC-DC charger for charging while driving

Flexible, Expandable & Built to Last

This system is designed to grow with your needs, offering long battery life, stable output, and flexible expansion options.

  • 4000+ cycle LiFePO4 battery
  • Expandable storage capacity
  • Reliable performance in real-world conditions

Important: All electrical work must be carried out by a suitably trained and qualified person. Battery installation and usage must comply with our Product Safety Guidelines. Improper installation may lead to safety hazards or void warranty.

Common Questions

Frequently Asked Questions

Which battery size should I choose?
Weekend trips with fridge and lights = 100Ah. Extended travel = 230Ah (most popular). Full-time = 280Ah or 314Ah. Call 1300 375 257 for help.
Can I install this myself?
DIY-friendly for 12V wiring. 240V AC must be done by a licensed electrician.
Will it run my air conditioner?
3000W handles small portable ACs. With 280Ah+ and solar, occasional use is feasible.
What warranty is included?
EVE cells 5yr, inverter 2yr, Jinko panels 25yr performance warranty.
Do I need the DC-DC charger?
If driving between spots, strongly recommended. Arrive with batteries topped up.
How long do LiFePO4 batteries last?
3,000-5,000 cycles = 10+ years daily use. 3-5x longer than lead-acid.
Why 24V instead of 12V?
24V systems draw half the current of 12V for the same power output. This means thinner cables, less heat, less voltage drop over longer cable runs, and more efficient operation with a 5kW inverter. Perfect for motorhomes, yachts & large caravans running heavy loads like A/C or washing machines. Your 240V appliances work exactly the same.
Will my 12V accessories still work?
12V devices need a 24V-to-12V DC converter (not included). Most owners use a small step-down converter. Your 240V appliances work perfectly through the inverter regardless of battery voltage.
What if something arrives faulty?
Contact us within 30 days with a photo or video. We replace any faulty component at no cost and cover return freight. No restocking fees on genuine faults.
Is this cheaper than buying separately?
Yes. The kit saves you 15-20% vs buying each component individually. Plus you get matched, pre-cut cables sized for this specific system.
Can I expand the system later?
Yes. More panels, bigger battery bank. We sell everything separately.
