RV Solar + Battery Designer is a connected RV electrical-system design tool. It is designed to model the loads you actually use, then consider solar, batteries, charging, inverter demand, vehicle/DC-DC charging, air conditioning, generator support and system limits together rather than sizing each component separately.

No. A battery can be large enough in amp-hours and still be unsuitable because it cannot accept the required charging current. A solar array can have enough watts and still exceed an MPPT voltage limit. The Designer is built around the complete electrical system and the relationships between its components.

The design structure supports caravans, motorhomes, campervans, converted buses, expedition trucks and custom RVs.

Both. You can start from the requirements and design a new system, or enter equipment you already own and analyse how that system performs before deciding whether anything needs to be changed.

No. Guided Mode is intended for RV owners with basic electrical knowledge. Advanced Mode exposes more technical inputs for experienced owners, installers and suppliers. Both modes work with the same saved design.
