Ray: I once submitted a warranty claim to Rolls which was rejected. There was a valid reason the claim was rejected along with some very suspect reasons. For example I was told that temperature compensation settings in the charge controllers did not meet spec, which was true, However the temp. comp. settings I used were more conservative than required. I acknowledged the valid reason and dropped my claim.
I have had many occasions where a client has asserted that batteries did not meet performance or longevity expectations and asked for warranty relief. My personal criteria is for the claim to include logging to prove the batteries were consistently charged sufficiently and never over-discharged. It should not matter one rip how the battery charge was maintained, be it by generator, grid, solar, thermonuclear reaction or black magic. It sounds like Rolls may be trying to duck the claim by asking irrelevant questions and making the process overly tedious. Good luck.

Greetings Wrenches and Steve Higgins; I'm having an issue with a recently installed single series string 48 v of Rolls S6 L16s. They are just over a year old, and we already have a dead cell in one of the batteries. My local supplier already gave us the pass, so we're going through the truly onerous warranty process directly with Rolls. They are literally asking for serial #s of the solar panels! Their online support portal is rough, it doesn't even have Outback on the drop down menu of inverters, and literally won't let me submit the info without choosing the inverter. We already filled out the and submitted the PDF form, but the portal wants me to reenter all the info again. Seems the idea is to waste so much time and energy, that we run away screaming and buy replacement batteries on our own. I now have several hours of my time and my customer's time wasted on what is an obvious manufacture defect. First: In 30 years in the industry, I have not had bad cells in the first year. This is not a good omen for the already dimming future of FLA batteries. Rolls L16s Did have a decent reputation. Second; I understand Rolls needs to weed out all the DIYers that trashed their batteries, but I'm a very long time reliable professional installer, and I need a replacement battery immediately. This is a single string, and we can't just rewire around the bad cell. Our Denver local supplier: Continental Battery Systems quit carrying Rolls, or any L16s now. We are totally dead in the water with this system, and very frustrated with both Rolls and my long time supply chain. Thanks, Ray Walters Solarray, inc. _______________________________________________ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org List Address: [email protected] Change listserver email address & settings: https://lists.re-wrenches.org/mailman/options/re-wrenches_lists.re-wrenches.org/ There are two list archives for searching.
