Off-Grid Appliances Planning Guide

An off-grid appliance plan is a ranked list of loads with honest hours. These sections build that list for one building.

1. Inventory every load

Walk the building and write down everything that will draw power: fridge, air conditioner, lights, fans, pumps, chargers, tools, entertainment and the small items everyone forgets, such as routers and phone chargers. For each, note whether it runs all day, cycles, or runs in bursts, and the hours it truly operates. An inventory written from memory underestimates the building; an inventory written on a walk-through does not.

2. Rank by consequence

Rank the loads by what happens when each stops. Cold storage failing costs stock and health. Lighting failing costs safety. Cooling failing costs comfort and sleep. Entertainment failing costs very little. This ranking is the plan: generation and battery are sized to protect the top of the list through the worst week, and the bottom of the list accepts interruption first. The appliances comparison shows the duty patterns behind this ranking.

3. Decide the backup expectation

State plainly how many sunless days the critical loads must survive, and what the building does on the day after that: reduce, reschedule, or use a backup source. Naming this in advance is the difference between a system that feels reliable and one that feels disappointing, even when both are the same hardware.

4. Confirm and inquire

Bring the inventory and ranking to the inquiry. The family pages for the solar fridge system and the solar air conditioner system explain how each is configured, and the remote sites guide covers buildings far from service networks.

Before ordering, confirm minimum order quantity and lead time for your configuration.

Run a one-week load diary

Before finalising the inventory, keep a load diary for one ordinary week. Each evening, note which appliances actually ran, roughly when, and anything unusual: guests, a market day, a hot spell, a delivery that kept the fridge door busy. Buildings routinely surprise their owners in these diaries: the water pump that runs more often than anyone thought, the freezer that arrived last year and joined the battery without a discussion, the staff member whose heater appears only on the coldest nights. The diary converts the inventory from a list of possessions into a picture of behaviour, and behaviour is what the battery experiences.

The diary also gives the backup conversation its facts. If the week's worst day still left the plan comfortable, the worst-week expectation may be generous. If one ordinary hot day already strained it, the ranking needs revisiting before the purchase, not after the first disappointing night. Either finding is valuable, and both are nearly free.

Assign the plan an owner

Finish by naming who owns the load list after the system is installed. That person approves additions, keeps the diary habit alive for the first season and is the one who says the sentence every off-grid building eventually needs: that load can join when something else rests, or when the system grows. Without a named owner, the inventory in section one is accurate for exactly one day, and every later change is invisible until the battery reports it at night. With one, the plan on this page stays the building's working constitution, amended openly as the building's life changes.
