Comparing efficiencies for AC vs DC-coupled batteries

Reading Time: 3 minutes

As is the case with comparing solar panels and inverters, when comparing solar batteries, there are a number of different technical specifications that differentiate one battery from another: power ratings, usable energy capacity, warranties throughput or cycles, start-up power, and the efficiency of the battery. Unlike solar panels and inverters, though, the stated efficiency of each battery is not necessarily directly comparable to the efficiency of other batteries. Here’s why:

AC vs. DC solar battery coupling: what you need to know

Reading Time: 4 minutes

Solar batteries are becoming popular additions to solar energy projects of all scales. When it comes to the way your solar panels, batteries, and inverters are all wired together on your property, there are two main options: alternating current (AC) coupling and direct current (DC) coupling. Both AC and DC coupling have advantages and drawbacks that are dependent on the specifics of your solar plus storage installation.
