Solar Commissioning Toolkit

The Blueprint Tells You How to Build It. The Toolkit Proves You Built It Right.

When your system is commissioned and running, three people may ask to see your documentation: a building inspector, a homeowner's insurance adjuster, or the buyer when you sell the property. Most DIY installers have nothing to show them. This is what you hand over.

Four Documents. All Field-Tested. None of Them Filler.

The 50-Point Commissioning Checklist

Five phases. Fifty line items. This is the go/no-go sequence you run before you energize the system — not after something trips. The phases follow installation order: pre-wire inspection, battery and BMS verification, charge controller setup and programming, inverter configuration and load testing, and final system sign-off. Each item is a checkbox with a specific condition to verify, not a vague reminder. When you reach item 50 and the last box is checked, the system is commissioned. That is what the document is designed to produce.

Wire Gauge and Ampacity Table

Covers conductor sizes from 18 AWG signal wire through 4/0 AWG main battery cable, with ampacity ratings for both open-air and conduit installation. Voltage drop percentages included so you can verify your run lengths before you pull wire. Formatted for a clipboard or a binder. You will not need to search anything when you are in the field.

Battery Maintenance Log

LiFePO4 banks are low-maintenance — not no-maintenance. This log gives you a structured record of your quarterly checks: resting voltage, state of charge, cell balance deviation, terminal torque verification, and any BMS events or alerts. A completed log is proof the bank was maintained to spec. It is also how you catch a drifting cell before it becomes a replacement.

Bill of Materials Template

Structured for an off-grid solar build: component name, manufacturer, model number, quantity, ampacity or wattage rating, purchase source, and cost. Fill it in as you build. When you are done, it is your system's permanent parts record — the first document a qualified electrician or inspector will ask for.

Who This Is For

This Toolkit is for builders who finish the job on paper the same way they finish it in the field — completely. If you want documentation you can put in front of an inspector without flinching, this is the set of documents you need. If you are buying the Blueprint and you are serious about the build, add this at checkout. It is fifteen dollars and it closes the loop.

A professional does not just wire it clean and call it done. He signs off on it. These are the documents you sign off with.
