Another way to buy more time with simplyphi would be to minimize LBCO hysteresis voltage and LBCO delay time. This would shut down the inverter sooner. They appear to be set at the defaults and could go lower.

Some have already implemented closed-loop integration such as Discover, other we are working with open-loop integration with Simpliphi, Fortress, Blue Ion, others. For the manufactures that are open loop, we have done extensive work with them, which included lab testing as well as support with the documentation. I have personally supported most of the manufacturers listed above; this includes Simpliphi and support of their documentation, related to the Schneider Electric setting. With the Conext XW Pro we are moving to SOC for many of these settings, that will integrate better than using voltage. Additional work of integrating these manufactures using Gateway through Modbus communication. I know that at times it seems very simple to make a programming change, but we as the manufacturers must look at the full picture of all the applications of the product and not create a conflict. An alternative would be a Simpliphi specifically firmware, this sounds very simple, but it is cost-prohibitive, as the product would have to be UL tested again. Each time we have to run a product through UL it will add to the cost of the product. It is a balance between the feature and staying competitive. I hope this help to cl;arify, let me know if you have any question Sandra Herrera sandra.herr...@se.com FROM: RE-wrenches ON BEHALF OF Ray SENT: Saturday, March 21, 2020 8:46 AM TO: re-wrenches@lists.re-wrenches.org SUBJECT: Re: [RE-wrenches] Lithium Ion Batteries [External email: Use caution with links and attachments] ------------------------- We've been having good luck with SImpliphi, the pricing has recently gotten much more competitive. As it's names states, its simple. Each 3.8 kWh unit has an 80 amp breaker built into the top, weigh about 75 lbs, and are a bit smaller than an L16 but with carry handles. We use an insulated 2 pole combiner block to run all the parallel conductors to the main 2/0 cable. No monitoring, but they do have an handy setup guide with recommended settings, specific for each manufacturer (including Outback). Note to all: Schneider XW can still not set its LVD above 48, which basically makes it incompatible with most Li+ batteries. Their tech support has been abysmal as well. We're looking forward to them as one of the larger companies in the business, to put additional resources into their engineering, and come out with at least a firmware update to correct this problem.

They are considering using Discover, Blue-Ion, Battle Born or SimpliPhi batteries. Does any one have any recommendations of which battery functions best with the Outback system.
