Choosing Your Batteries
Whether you live in the wilderness off grid batteries or have to stay off the grid due to environmental factors, off grid batteries can give you the peace of mind that your home has a way to power its electronics when there’s no electricity available. They can also help you to avoid the costs and inconveniences of using the utility grid.
Choosing Your Batteries
There are two main battery chemistries used in off grid systems; lead acid (flooded or sealed) and lithium. Each has its own advantages and disadvantages and is ideal for different situations.
The most common battery chemistry is flooded lead-acid, but there are many options that can meet your needs. Lithium iron phosphate (LiFePO4) is an ultra-safe, maintenance-free and highly durable chemistry that’s designed for a significant number of charge cycles.

Another type of battery that is popular among preppers are nickel-iron batteries, often referred to as Edison cells. They are extremely long-lasting and resist damage from over- and undercharging, making them an excellent choice for many off-grid applications.
Both chemistries are available in a wide range of battery sizes, and each is compatible with an array of solar inverter-chargers. The best off-grid inverter-chargers provide programmable charge voltage settings and temperature sensors to precisely charge the battery under all conditions. They also allow you to match custom charge setpoints to ensure optimal battery health and safety. Moreover, they are compatible with most off-grid lithium batteries. The Morningstar Energy Storage Partner program is an excellent resource for obtaining the information you need to choose a battery system that works with your specific application.
