Fellow Wrenches, Two requests, please, for the same job: We have a GTWB (grid-tie with backup) job coming up for which we need to include an ATS (automatic transfer switch). The utility pays RECs, but the critical loads must pass through the REC meter > main load center > transfer switch > critical loads panel in order to be counted. The customer has requested an automatic transfer switch, rather than the usual manual switch, for this application. It's an Outback GVFX3648-based system, that may or may not include a PSX-240 autotransformer to produce 240VAC - it depends on whether we have any mulitwire branch circuits that can't be reconfigured. My request is for recommendations of a basic and inexpensive, but adequate and reliable, 30A 240V ATS, to switch from grid to inverter when the grid goes out. I would also like a recommendation of a 60A version, either straight 120V or 240V, in case we don't need the transformer. The home also will need a full service upgrade. There are now All-in-one meter base/main load centers offered as PV-ready - to satisfy NEC 690-64(b)2 bussbar issues. I have seen mention of such on this list, but can't find the posts. Could someone post or send me a link to such a panel? We're upgrading the existing 100A to 150-200A, mainly to correct old New Mexico funk. Thank you for any assistance. Allan --
