Battery technology has come a long way in the last several years, bringing better and safer options into the realm of affordability for the typical homeowner. We have many years of experience installing battery systems from large to small, for backup, self-consumption, or as the main storage unit of an off-grid system.
Batteries come in many shapes, sizes, and chemistries. Two of the most popular types are lead acid and lithium, both of which have several sub-categories. Flooded Lead Acid (FLA) batteries are a type of lead acid battery and have been the standard workhorse for backup and off-grid systems for many years, and we have installed many of these systems. However, lithium batteries have become much cheaper and more widely available in the past decade, and we now recommend lithium batteries in most circumstances. One of the safest chemistries is Lithium Ferro-Phosphate (LiFePo) which is used by in the batteries we most commonly install.
