It depends on may factors. For example, many of our customers are only using their system seasonally. When away for up to 6 months, an AGM or GEL battery will be far superior unless you have a knowledgable person servicing the bank every month. If your customer is not fully dedicated to understanding and then actually caring out all the requirements of owning a flooded bank (watering, equalizing, keeping a log book, testing, cleaning, …), then I would not suggest FLA. </div><div><br></div><div>Chris, designing and installing battery based systems require lots of understanding. You will likely be the one educating your customer and resolving problems for many years. The single most important item to install in any off grid system is a battery capacity meter. Its like a fuel gauge so you can see what you are doing with your battery bank. Check out Blue Sky Energy and Bogart Engineering.<br><div><br></div><div>Suggesting Rolls (very high quality) and Interstate (cheapest battery from JC) in the same sentence…well, that just made my teeth hurt. <div><br><div apple-content-edited="true">Larry <div><br><br></div>

Also nickel iron no not metal "iron" cost alot but you should never need to replace them my last set was 35k for 900 amps<br>

<div dir="ltr">We don't do a lot of off-grid systems so I am short on experience with battery systems. I have a 8KW Radian system for which I am considering Rolls Surrette or Outback 200RE AGM batteries. I know people like the Surrettes, what is the experience with the outback battery system? <br clear="all">
