The Kit Ladder

Start where you are. Scale when you're ready.

Each tier is a complete, tested kit — not a parts list. Pick the one that matches your space today, and add tiers as your needs grow.

The Process

Four steps from box to powered.

No mystery, no middlemen. Every kit ships with everything you need and instructions written for DIYers, not electricians.

01

Choose Your Tier

Answer six questions about your space — size, existing power, intended use — and we'll confirm the right kit. Free consult call included for Tier 3.

02

Kit Ships to You

Pre-configured components, pre-cut wiring harnesses, and a laminated install guide. Everything fits in two boxes, sized for a standard truck bed.

03

Install in a Weekend

Most Tier 1 and 2 installs take 4–8 hours with two people. Video walkthroughs cover every step. Live chat support on install day.

04

Monitor & Optimize

The Craftstrom app shows live solar production and consumption. Open-source controls let you dial in schedules, temp setpoints, and grid response.

Curated Hardware

Every component earns its place.

We don't manufacture — we select. Every product in an EcoSnap kit has been installed, tested, and iterated in real small spaces across multiple climates.

🌡️

Quick-Connect Mini Split

Pre-charged refrigerant lines with a tool-free snap connection. No HVAC certification needed for the line set. Fujitsu and Mitsubishi units available by climate zone.

Heating & Cooling
☀️

Plug-In Solar (Craftstrom)

200W panels with a 350W HEDY microinverter that plugs into any standard 120V outlet. Stackable to 800W with no additional permits in most jurisdictions.

Solar Generation
🔋

Buffer Battery Kit

1–3 kWh LFP battery handles compressor startup surges and stores midday solar for evening use. Designed around our peak-constraint control system, not just efficiency.

Storage
🍳

Induction Cooktop

1800W two-burner portable induction — no gas line, no venting, no CO risk. Faster than gas, easier to clean, and safe for tight spaces with limited ventilation.

Cooking
📊

Smart Subpanel & Meter

Square D QO panel with Craftstrom PowerMeter integrated. Real-time production and consumption data in the app. Foundation for demand response and load shifting.

Electrical
🔧

Open-Source Controls

ESP32-based control board with community-developed firmware. Works with most mini split brands via IR or direct serial. Schedules, setpoints, and grid signals — all local, no subscription.

Controls & Automation

Built by people who've installed this stuff, not sold it.

No manufacturer lock-in

We curate the best components from multiple brands. When better hardware ships, we update the kit — your existing system stays compatible.

Open controls, not a subscription

Our control layer is open-source. Your data stays local. No cloud dependency that disappears when a startup pivots.

Tested across real climates

From Colorado winters to Pacific Northwest damp to Minnesota cold — our kits have field hours in conditions that matter, not just California sun.

Designed for the next step

Every kit is architected to be a building block — Tier 1 wiring is Tier 2-ready, Tier 2 controls anticipate grid response. You don't rip and replace.

The cheapest clean energy system is the one a competent DIYer can actually install.
