SolarWiringSimLab

SolarWiringSimLab is a mobile application designed for educational, planning, and simulation purposes in the context of small-scale solar electrical systems. It provides a visual platform for users to create and analyze simplified solar wiring layouts for environments such as RVs, camper vans, tiny houses, boats, cabins, and other small off-grid setups. The app features a 2D Visual Wiring Canvas that enables users to build solar electrical systems and visualize how components—such as solar panels, MPPT charge controllers, batteries, DC busbars, fuses, breakers, inverters, DC and AC loads, and wiring paths—connect together.

The application allows users to perform calculations related to system values, including battery runtime, solar energy production, inverter load, wire size, voltage drop, fuse rating, and breaker protection. It also provides simplified safety warnings for common design issues, such as missing protection devices, low solar production, inverter overload, and insufficient battery capacity. SolarWiringSimLab offers ready-made templates for frequently encountered setups, including Basic RV Solar, Camper Van Power, Tiny House Starter, Boat DC System, and Off-Grid Cabin, which can be edited and analyzed within the app. Users can save their projects locally on their devices, with all project data—including component values and system parameters—retained only on the device and not uploaded to any external servers or cloud services.

The app operates entirely offline for its main functionality and does not require an internet connection. It does not request access to sensitive device permissions such as location, camera, microphone, or contacts, nor does it use advertising tracking, user profiling, or third-party advertising networks. SolarWiringSimLab does not require user accounts, registration, or the submission of any personal information, and it is designed to maximize user privacy and data security by keeping all data local. If the app is deleted from the device, saved project data is also deleted and cannot be recovered by the developer.

Payment processing, if a one-time purchase is required, is handled through the Apple App Store, and the app itself does not process or store payment card information. SolarWiringSimLab is not intended to provide certified engineering advice, professional installation guidance, or code compliance approval, and users are advised to consult qualified professionals for any real-world electrical work.
