When transitioning from a tent to a camper trailer, understanding power consumption off the grid becomes essential. This blog post provides a brief overview of power considerations without delving into the intricacies. We’ll explore the shift from AGM to lithium batteries and the benefits they offer. Additionally, we’ll touch upon scalable systems and the importance of understanding your power requirements.

Lithium vs. AGM Batteries

There are two main types of batteries used in off-grid camper trailers: lithium and AGM. Lithium batteries are more expensive than AGM batteries, but they offer several advantages, including:

  • Longer lifespan. Lithium batteries can last for up to 10 years, while AGM batteries typically only last for 5-7 years.
  • Lighter weight. Lithium batteries are much lighter than AGM batteries, which can make them a better option for camper trailers.
  • More efficient. Lithium batteries are more efficient than AGM batteries, which means they can store more power for their size.
  • Faster Charging: Lithium batteries have a higher charge acceptance rate, allowing them to recharge at a faster rate than AGM batteries. This feature is particularly useful when relying on solar power or limited charging opportunities while on the road, enabling quicker replenishment of the battery bank.
  • Depth of Discharge: Lithium batteries can be discharged to a much lower capacity than AGM batteries without risking damage or significantly impacting their lifespan. This flexibility provides campers with a greater usable capacity and ensures a more reliable power supply even during extended off-grid adventures.
  1. The Shift from AGM to Lithium:

In the past, many setups relied on 2x 100Ah AGM batteries, roughly equivalent to a 100Ah lithium battery. However, with advancements in technology and the increased efficiency and affordability of lithium batteries, they have become a sensible choice. For those upgrading from a tent to a camper trailer, a minimum of 100Ah lithium battery capacity, paired with 200W of solar, is usually sufficient, however larger capacities may be required as your power requirements increase or if you’re looking to be off grid for extended periods of time.

  1. Scalable Systems:

The best power systems for campers are those that can be expanded over time. Premium manufacturers often offer 200Ah lithium systems as a base, with options to increase capacity down the track as needed. Additionally, these higher-end systems will likely run 400W+ solar arrays. Scalability is crucial, as it allows you to adapt your power setup to your evolving needs and ensures long-term usability & resale value as newer base systems capacity tend to increase overtime as the technology improves.

  1. Remote Solar Connection Points:

Manufacturers that focus on providing their customers with off-grid systems will incorporate a remote solar connection point in addition to their fixed solar array, such as rooftop solar. This allows for the addition of extra panels or solar blankets to be added, boosting charge rates on sunny days. Moreover, having a remote solar connection point provides the flexibility to park in shaded areas while still harnessing solar power.

  1. Calculating Your Power Requirements:

Determining your power consumption and the necessary system size can be challenging. Working closely with your supplier is recommended to assess your specific requirements. While it may seem daunting, remember that it’s better to have more power than you initially think you need.

  1. Advanced Monitoring and Controls:

Modern power systems often feature touchscreen live monitoring of battery status and consumption, such as the Rhinomax Digital Control System. This real-time feedback allows campers to stay informed about their energy usage and tailor their decisions for optimal power management & consumption when off-grid.


At Rhinomax, we understand the importance of tailoring power systems to our customers’ needs. Whether you’re a low-power user or require more comprehensive setups, we work closely with you to scale the system accordingly. Remember, power consumption off the grid is an essential consideration, and investing in the right system ensures a comfortable and uninterrupted camping experience.
