Trip Power Planner
Use this tool to estimate how your battery, solar panel, and charging sources work together on a typical day. The numbers are planning estimates for a 12 V system—real-world conditions will vary.
Trailer & Trip Basics
Trailer model
Trailer year
Simple mode uses model + year to estimate your battery and charging setup. Advanced mode lets you override everything.
Usage style
Presets assume an efficient 12 V fridge plus a mix of fan, lights, and small loads common to Timberleaf trailers.
Solar
Panel
Sun conditions
This scales the solar estimate up or down from a clear, good-sun day.
Simple mode assumes typical mixed sun for the solar estimate.
Battery
Battery type
Lithium can safely use more of its capacity. AGM is usually planned around 50% depth of discharge.
Battery size
Driving & Charging
Trip length
We’ll ask how much you drive on each day to estimate DC-DC charging.
Driving per day
Post-2024 trailers include an 8 A DC-DC charger. We’ll estimate vehicle charging from your driving hours.
Vehicle charging
Charge rate
Most Timberleaf trailers use an 8 A DC-DC charger.
Driving per day
Estimated hours of driving per day.
Shore power
Charge rate
Auto-filled based on battery + trailer year.
Hours on shore
Solar & Battery Overview
| Panel watts | 0 W (effective: 0 W) |
|---|---|
| Solar charging | 0.0 Ah/day |
| Vehicle charging | 0.0 Ah/day |
| Shore charging | 0.0 Ah/day |
| Total charging | 0.0 Ah/day |
| Battery size | 100 Ah (Lithium) |
| Usable capacity | 80.0 Ah |
Charging estimates include solar, vehicle DC-DC, and any shore-power charging you’ve entered.
Daily Balance
| Daily load | 0.0 Ah/day |
|---|---|
| Total charging | 0.0 Ah/day |
| Net balance | 0.0 Ah/day |
On a typical day, your charging should keep up with this load.
Runtime Estimates
| Battery only | ∞ |
|---|---|
| Battery w/ charging | ∞ |
| Days to recharge | ∞ |
Estimates assume similar sun, driving, and plug-in time each day.
Trip Overview
| Daily load | 0.0 Ah/day |
|---|---|
| Total charging | 0.0 Ah/day |
| Net balance | 0.0 Ah/day |
| Battery only | ∞ |
| Battery w/ charging | ∞ |
| Days to recharge | ∞ |
This is a planning estimate based on your trailer, year, trip length, and driving time.
