YOUR USE BEFORE THE PRODUCT
What is your project?
Choose the context that matches your project. The configuration then accounts for real-world use constraints.
OFF-GRID
Cabin / Off-grid
Systems designed for partial or complete autonomy, adapted to space, climate and access constraints.
View recommendations →
MOBILITY
Camper van / Adventure
Compact, lightweight and reliable mobile solutions, designed for real life on the road.
View recommendations →RECOMMENDATION METHOD
A clear, structured method
Each recommendation follows a clear method based on need, compatibility and real-world use.
Needs analysis
Real-world use is the starting point: home, cabin, RV, desired autonomy and technical constraints.
Technical comparison
Capacity, weight, efficiency, compatibility, service life and operating conditions are assessed objectively.
Usage context
Climate, mobility, available space and budget directly influence the choice of solution.
Clear recommendation
Suitable options, their limits and less appropriate choices are presented clearly.
STARTING POINTS
A few recommendations for the most common uses
Residential lithium battery (10–15 kWh)
- Ideal for
- Home or cabin requiring storage and partial autonomy
- Strengths
- Long service life (6,000+ cycles)
- High safety (LFP technology)
- Easy to expand over time
- Watch for
- Sizing must match actual consumption, otherwise the battery will be undersized or oversized.
Compact solar kit for RV / Camper van
- Ideal for
- Converted vehicles and mobile use
- Strengths
- Lightweight and compact
- Relatively simple installation
- Good output for the available surface area
- Watch for
- Space and weight are critical. An overly ambitious system quickly becomes impractical.
Three-season cabin autonomy system
- Ideal for
- Intermittent off-grid use (spring through fall)
- Strengths
- Good balance between generation and storage
- More reasonable cost than complete autonomy
- Suited to the real needs of most cabins
- Watch for
- Solar production drops sharply in winter. This must be planned for.
