I asked AI to design and buy a solar power system for me
And it worked.
- 3x Aiko Neostar 3P54 wired in serial at 123Voc
- 4x 220Ah 12V batteries wired as 2S2P for 440Ah at 24V
- SmartSolar MPPT 150/85-Tr
- MultiPlus-II 24/3000
- Ekrano GX
- Orion-Tr Smart 24/12-30
- SmartShunt IP65 500 A
- 2x Victron battery balancer
This is for a small village on a remote island halfway between Fiji and Tonga. They wanted to run Starlink with a Unifi voucher system, charge USB devices, have some indoor lights, and sometimes run the inverter for power tools or a fridge. It's very difficult to get batteries here, so the system is designed to maximize battery life.
The tool I built tracks components, costs, weight (everything was hand-carried on commercial airlines except batteries and solar panels), port types and terminal sizes, power requirements, current ratings, and other integration tests. It also tracks and stages Amazon purchases and tells me whether things will arrive on time.
I put the most work into the auto-routing and auto-layout system. All the components are positioned and connected automatically using an algorithm that is basically A* pathfinding over a 3d grid with carefully defined costs. The layouts and routes aren't perfect, but they are much, much better than what you might get out of the box.
My design approach for the app is that I didn't want any traditional UI for adding, removing, managing, moving, or routing. I wanted a chat-only interface. So this means there is no way to download or use this like an "app", but if you ask an agent to copy the repo then you'll have a good starting point for building your own system by describing what you want.
The installation is not perfect. The photo is from before the cables were tied down, before the batteries had a protective covering, and a few other details. But it works, and it has been working without a single change for about a month now.
