We spent 27 hours on research, videography, and editing, to review the top choices for this wiki. Modern battery technology is one of the most important advances of our era, especially for anyone with residential and mobile solar setups. Of the several varieties available, the absorbent glass mat and lithium iron phosphate types have emerged as the safest, most efficient, and most consistent. Here are some of the best secondary deep-cycle models, with options in a wide range of prices. When users buy our independently chosen editorial picks, we may earn commissions to support our work.

Editor's Notes

December 06, 2018: First of all, flooded and gel-type lead-acid batteries are simply not recommended for modern solar energy systems. They're inefficient, expensive to produce, and potentially dangerous. So, until Elon Musk figures out something new, it's LiFePO4 vs. lead-acid, each of which have advantages and disadvantages. If you don't want to make a huge investment, the Universal is a perfect choice. Those in search of more capacity and better regulation should look at the Orient Power, but keep in mind that LiFePO4 batteries lack the nearly fool-proof safety of the AGM variety. The Renogy LFP offers about the most usable energy storage you'll find, though at a high premium. And the Battle Born is a seriously solid device; it's probably the longest-lasting of all.
