Powering Your Journey: Navigating Battery Choices and Solar Options
Your trailer’s power system is what turns a cozy cabin on wheels into a true basecamp. It keeps the lights on, the fridge cold, and your devices charged when you’re miles from the nearest outlet.
Every powered Timberleaf starts with a modern lithium battery system and an integrated charging package. From there, you choose how much capacity you want on board and whether to add solar for true off-grid independence.
A Modern Foundation: Lithium Power, Standard
Every powered Timberleaf trailer ships with a lithium battery system. Lithium is lighter, more efficient, and delivers more usable energy than older battery technology. It charges quickly from shore power, your tow vehicle, or solar, and holds that energy reliably until you’re ready to head out.
The result is simple: more nights off-grid, less time waiting on a charger, and a power system that quietly does its job while you enjoy the trip.

Battery Size: Match Your System to Your Style
Your battery bank is your energy tank. The main decision is capacity: how big do you want that tank to be for the way you actually camp?
100Ah Lithium — Weekender Setup
A great fit if you:
- Take 2–3 night trips with occasional hookups
- Use cabin and galley lights each night
- Run the vent fan for sleeping comfort
- Charge phones, tablets, and smaller devices
100Ah keeps things simple, light, and efficient if you move regularly and don’t rely on a 12V fridge full-time. Solar is optional here, but adding a 200W panel extends your flexibility in sunny conditions.
300Ah Lithium — Off-Grid & Long-Stay Setup
Best suited for owners who:
- Camp 3–7 nights at a time without hookups
- Run a 12V electric fridge full-time
- Charge laptops, cameras, and drone batteries
- Want margin for hot days and cloudy stretches
Paired with solar, 300Ah turns your trailer into a compact, capable cabin that can stay off-grid comfortably for extended periods.
Most popular choice for off-grid travel: 300Ah lithium + 200W portable solar.
The Fridge Factor
A 12V electric fridge is one of the biggest “this changes everything” upgrades you can make. No melting ice, no soggy food, and no daily runs into town for a bag of cubes.
It’s also one of the largest continuous electrical loads in a small trailer. If a fridge is part of your plan, we strongly recommend building around 300Ah of battery capacity and a 200W portable solar panel. That combination keeps your food cold and your power anxiety low, even in heat or on cloudy days.

Solar: Turn Your Battery into a Renewable Resource
Solar lets you refill what you use each day instead of watching your charge level slowly drop. Park the trailer where it’s level and comfortable, set your panel where the sun is best, and let it quietly work in the background.
200W Portable Solar (Bluetti PV200)
Our recommended solar solution for every powered Timberleaf trailer. A 200W folding panel provides meaningful real-world output and pairs well with both 100Ah and 300Ah systems, especially when running a fridge.
- Typical output: roughly 60–80Ah per clear day in good sun
- Supports: full-time 12V fridge, vent fan, cabin lighting, and daily device charging
Every Timberleaf includes an exterior SAE solar port. The Bluetti panel uses standard MC4 connectors; we provide a dedicated MC4-to-SAE adapter harness so it plugs straight into your trailer’s existing port with no rewiring or guesswork.

Recommended Panel Snapshot: Bluetti PV200
- Output: 200W portable solar panel
- Cell type: high-efficiency monocrystalline (up to 23.4%)
- Lamination: ETFE for durability and UV resistance
- Connectors: MC4, paired with Timberleaf’s MC4-to-SAE adapter harness
- Form factor: lightweight folding design that stows easily in the cabin or galley
Paired with the Victron MPPT solar charge controller in every powered Timberleaf, the Bluetti PV200 is a simple, robust way to keep your system topped up wherever you park.
Which Power Setup Fits You?
Still deciding? These simple profiles map to how many of our customers actually use their trailers.
The Weekend Escaper
2–3 nights, some hookups, minimal electronics.
Recommended:
100Ah lithium.
Solar optional; 200W is a great upgrade in sunny climates.
The Off-Grid Explorer
3–7 nights off-grid with a 12V fridge running full-time.
Recommended:
300Ah lithium + 200W portable solar (Bluetti PV200).
Our most common off-grid setup.
The Remote Worker
Longer trips with laptops, cameras, and drone gear in the mix.
Recommended:
300Ah lithium + 200W solar + 375W inverter.
Smart Monitoring and Clean Integration
Every powered Timberleaf trailer includes a Victron BMV-712 battery monitor, Victron MPPT 75|15 solar charge controller, PowerWerx 8A DC-DC charger, and PD4045KA power center. Together, they handle charging from shore power, your tow vehicle, and solar as a single, integrated system.
The BMV-712 with Bluetooth gives you a clear window into that system: state of charge, voltage, current flow, and estimated time remaining. Instead of guessing, you can see at a glance how your usage and charging are balancing out.
If you’d like to power select AC devices, an optional 375W inverter can be added for items like a CPAP, laptop chargers, or small accessories—without relying on campground hookups.
Build the Power System Your Adventures Deserve
The right power system turns your Timberleaf from “a place to sleep” into a capable, independent basecamp. Whether you’re planning weekend escapes or longer off-grid routes, you can configure a battery, solar, and inverter package that fits how you travel.
