DoD Explained—What Your Battery Really Delivers

When investing in a solar battery system, it’s important to understand one key factor that determines your system’s real performance — usable capacity.
Many people assume that the total capacity shown on a battery label is the amount of energy they can actually use. However, that’s not always the case. Let’s break down what “usable capacity” really means and how it affects your solar savings.
What Is DoD?
Usable capacity refers to the amount of energy your solar battery can safely discharge without damaging its lifespan or efficiency. For example, if you have a 10 kWh battery but only 9 kWh is usable, that means 1 kWh is reserved as protection to maintain the health and performance of the battery.
Why It’s Different from Total Capacity
Every solar battery has a total capacity (the full energy it can theoretically store) and a usable capacity (the portion that’s actually available). The difference comes from the Depth of Discharge (DoD) — the percentage of the battery that can be used before it needs recharging.
A battery with a 90% DoD allows you to use 90% of its total capacity.
High-quality batteries, like those offered by SolarMatchAu, are designed with higher DoD levels, meaning you can access more of your stored energy.
Why DoD Matters
Knowing your battery’s usable capacity helps you:
Accurately calculate how much power you can use during peak times or at night.
Avoid unexpected shortages when your home depends on stored solar energy.
Maximize your investment by choosing a system that truly delivers what you pay for.
