Three questions that are really one: what goes in, what comes out, and what is actually left.
Almost every autonomy problem aboard is an accounting problem. The bank is rated at one figure and usable at another, the panels are rated in a laboratory and shaded in a marina, and the appliances draw what their plates claim until you put a clamp meter on them. The Electrical and Power Command Kit is the whole cluster bought at once, so the three sides of the sum are measured the same way and meet in the middle.
What is in the kit
Generation, storage and consumption, measured the same way
- Lithium & DC System Record, configuration, commissioning and sixteen cell-balance entries over the life of the bank, 37 pages
- Solar & Hydro Yield Record, array configuration, a ten-observation shading survey and twenty-four months of specific yield, 43 pages
- 12V Load & Energy Budget Worksheet, 28 loads with the plate figure beside the measured figure, split across four operating regimes, 38 pages
02Why the three together beat the three apartUsable capacity comes off the lithium record.1 min
Usable capacity comes off the lithium record. Daily generation comes off the yield log. Daily consumption comes off the load worksheet, measured at the shunt rather than read off a data plate. Only when all three are yours do the autonomy models mean anything, and the gap between the plate and the shunt is usually the reason the sum never balanced before.
03Where to start, by how you use the powerThe boat at anchor for days at a time.1 min
The boat at anchor for days at a time. Load worksheet first, measured at the shunt. Autonomy problems at anchor are almost always consumption problems that were never measured, and generation cannot be sized against a guess.
The boat that has just been refitted to lithium. The commissioning pages, this season, while the bank is new. Cell balance is only meaningful against the day it was installed, and the verification page with the electrician's qualification on it is what your insurer will want.
The boat on passage. Yield by month is your page. An array that carries you through July does not carry you through a passage in the shoulder season, and specific yield across twenty-four months is what tells you which months are which.
The rule every document in the kit obeys
Not one published voltage, current limit, charge parameter or cell tolerance anywhere in 118 pages + 9-page Kit Guide. Those belong to your cell maker, your BMS, your charge controller and your inverter. Each document opens with a reference page where you transcribe your own figures from your own documentation, and the lithium record keeps a separate sixteen-line page recording that a competent person verified the installation, with their qualification and date.

As a kit, the three documents cost less than bought one at a time (the price block on this page works out the exact figures from current prices), and the three sides of the energy sum are finally measured on the same terms.
05What it is notThese documents record and organise.1 min
These documents record and organise. They are not an installation guide, not electrical advice, and they reach no conclusion about the safety of any system. Lithium installation and commissioning are work for a qualified marine electrician.
Instant download. Your links appear on screen the moment payment clears, and a copy arrives by email, usually within a few minutes. They do not expire.

Questions
Before you buy the Electrical & Power Command Kit
The five questions asked about every document, answered for this kit.
Which file do I open first?
Open the Start here page, then the Kit Guide: it sets the order of work across the three records. Every document and the Kit Guide come in two editions, each in A4 and US Letter. Type in Adobe Acrobat Reader, which is free, or write by hand in GoodNotes, Notability or on paper.
Does it calculate on iPhone or Android?
Yes. In Adobe Acrobat Reader on iPhone or Android every document in the kit calculates as it does on a computer, and the Kit Guide sorts every check by date for you. Entries are saved into the files: no app of ours, no account, no connection.
What does it deliberately not contain?
An installation guide or electrical advice. The three records keep your own figures and reach no conclusion about the safety of any system; lithium work belongs to a qualified marine electrician.
Does the kit suit a power boat?
Yes. Any boat with a DC system, 12V or 24V, any chemistry, with or without solar or hydro.
A4 or US Letter?
Both, for every file in the kit, in both editions. Choose by the paper you print on: A4 in Australia, New Zealand and Europe, US Letter in the United States and Canada. The pages and fields are the same in each.
