Lithium ion solar battery bank
Introduction
Lithium batteries are a great choice for solar power systems. They are especially forgiving when it comes to the level of discharge they will tolerate. Said another way, you can safely go up to a 100% depth of discharge (DoD) while maintaining nearly 98% efficiency. Many of the lithium deep cycle batteries we offer have a cycle life north of 10,000 cycles (at 80% DoD)!
Lithium batteries work well in solar systems with battery backup because they can be charged up and do not require maintenance.
Many lithium solar batteries come equipped with a built in battery management system (also known as a BMS). Battery management systems are designed to protect batteries by ensuring they are operating within the manufacturers' desired parameters. Parameters monitored by the BMS could include state of charge (SoC), voltage, or temperature of the battery. It’s no secret there is a higher initial capital outlay when buying lithium deep cycle batteries. The BMS is a great built-in feature because it automatically helps protect your investment in the battery by shutting it down if the BMS detects something wrong.
Advantage
Higher depth of discharge (DoD)
The DoD of a battery is the amount of the stored energy in the battery that has been used, as compared to the total capacity of the battery. Most batteries come with a recommended DoD in order to maintain the health of the battery.
Lithium ion solar batteries are deep cycle batteries, so they have DoDs around 95%. Many lead acid batteries only have a DoD of 50%. This means you can use more of the energy that’s stored in a lithium ion battery without having to charge it as often.
