My nine year old lead acid bank was dead, and I was tired of dealing with replacing another bank of lead batteries. Most of my neighbors also struggle with lead acid banks at one time or another. Conversely, the Ni-Fe cells don't have the same inherent problems. They make my system so much easier and more dependable.

I went with the Iron Edison battery because I was needing a battery to supply power to my home and workshop. We are in a grid-tied situation, but I would like to eventually switch to an off-grid system. The Iron Edison batteries are well made and sturdy looking. I really like the large lugs for connecting cables. Brandon and Maggie were both great to work with and I would definitely recommend Iron Edison to others. I had been searching for some time to buy batteries and all the accessories from, and I feel I have found the right place.

My problem was that I did not understand how to put all the proper components together to form an off-grid system. Iron Edison helped explain everything to me. My Iron Edison batteries are 100% reliable and the service is second to none.

I enjoyed working with Iron Edison. They helped me solve my problem quickly and were honest and reliable. I would recommend working with them again.

I chose the Iron Edison battery due to its long life and low maintenance. How could anyone not be pleased with Iron Edison's product and the after sales follow up? The experience was most enjoyable and rewarding.

I have a trailer with solar panels and I have to leave them alone for winter when I cannot reach the place. A lead acid battery would never survive the freezing cold. Also, I was really happy to see everything was included to get my battery up and running.

Cost was not why I bought Ni-Fe batteries, it was in consideration of the environment. It would be cheaper for me to use utility power, but that's not why I do it. I do it because we have a power monopoly here in Hawaii, I don't support monopolies, no matter what the price is. I was worried about batteries not delivering high current, they do. I was surprised when the battery capacity got better with hard use. I'm learning that the battery likes to be cycled hard.

I like that I don't have to worry about running these batteries under 50% state of charge. We have drawn our battery all the way down, with no ill effects on the capacity. Flooded lead acids would have likely been destroyed, or at least we would have taken a few years off their life span! Here we are unloading the batteries.

I really like the people at Iron Edison. The regular updates/communications were above and beyond. I would ABSOLUTELY recommend my friends, family and co-workers to Iron Edison!

We were switching from grid-tied to off-grid, and I wanted a US distributor of nickel iron batteries due to their long life. I enjoyed the one-on-one conversations with Iron Edison to determine which battery was right for me.

Off-grid in Hawaii

I came to Iron Edison because a friend here on Hawaii strongly recommended them to me. Even requiring the shipping, he said, it is well worth buying batteries from Iron Edison. He said I wouldn't regret it. As well as my batteries I ended up buying my entire solar system from Iron Edison because I found the price was comparable to buying here on the Island despite the shipping. I found my initial phone calls with the owner Brandon, very informative and personable yet highly professional and I felt very encouraged. Since then Maggie (who is the other owner with her husband) has worked diligently with me, her system designer and my solar installer to make sure the whole process run smoothly for me and I get the best possible system for my particular needs.. She has always been very available and graciously accommodating with the details and any changes that had to be made and a pleasure to work with. I have found myself in excellent hands.The piece of mind has been invaluable. A company as conscientious and with the kind of integrity I have experienced working with Maggie is extremely hard to find!
