Hi all, We are scheduling our next Enphase system now using the new Envoy-S and S280 micros. Reminds me of the Tesla S for some reason, like the data sheets on the Envoy-S Envoy-S is the platform for total energy management and integrates with the Enphase AC Battery. The Enphase S280 also eludes to this The S280 is compatible with storage systems, including battery management systems.
Our primary reason for the S280 is more output with 310 watt LG NeON2 modules, not the potential with the battery interface, although this didnt go unnoticed! We didnt attend the shows, and now you have me wondering what is around the corner, as our client is also wanting to head into a battery based system one day.

It wouldn't be perfect, but a significant improvement.

Sounded like it would be another year at least before they staart selling it for battery backup systems. But...we will see. I also think the Outback GSLC175-AC-120/240 is a good choice for integration with Enphase. But since their ROCB is basically a blackout relay the system isn't likely to ever 3 stage charge lead acid batteries when the grid is down, so if this guy really thinks the grid is going down forever you might not want to mention that to him. This is much better design for grid-tied battery backup systems with lead acid which wouldn't be damaged  just hitting bulk voltage and not going through absorb the few times a year the grid is likely to be down. Rebekah On Mon, Oct 26, 2015 at 9:51 AM, Drake < drake.chamber...@redwoodalliance.org <mailto:drake.chamber...@redwoodalliance.org> > wrote: Hello Dan, We are preparing to install a similar system. Enphase now allows AC coupling. We have specified the Radian. The batteries will be Concorde AGM, either 305 or 405 AH. Concorde AGMs are useful because they can take a very fast charge rate. With over 6 kW available to charge batteries, the charge rate would exceed C/5 for an L-16 battery, which the Concorde L-16 (405 AH) can easily handle with one string. The Concorde 305 AH can handle it also. The Radian 8048 can AC couple 6kW. The Radian GSLC175-AC-120/240 load center is set up for AC coupling.

He has ~6kW of Enphase and wants to add battery backup for critical loads.....quite a few of them. I recommended he buy some Kill-a-Watt units and start to monitor kWh usage.à My first thought was the new Enphase "AC Battery system." Is this even available for purchase yet, and if so has anyone here tried it? I'm thinking ease if compatibility, tech support, warranty...... Otherwise will likely AC couple a new inverter.àI was thinking an Outback Radian, and lithium batteries (looking at Iron Edison) as my prediction is they will be mostly sitting idle for the next 10 years at least. Any pitfalls, horror stories, and no-nos anyone is willing to share? Crossed off NiFe; my house runs on them and they are fairly high-maintenance, as I predict this client will be.
