Off-Grid Sprinter Electrical System

I'm looking for a skilled electrician or solar power expert to design and install a self-sufficient electrical system in my sprinter van. The system needs to be powered by solar panels and should be adequate for full-time living.

The primary usage of this system will be running climate control (AC), and the fridge is the most critical component that needs constant power. Occasionally, I will also be using a cooktop, air fryer, fan, and charging devices.

Key requirements:
- Solar panel setup
- Sufficient battery storage
- Reliable power management system
- Safety and code compliance

Ideal skills and experience:
- Experience with van conversions
- Knowledge of solar power systems
- Electrical system design and installation
- Familiarity with living off-grid

Please provide a detailed plan and itemized budget.
