[RE-wrenches] EG4 18kPV Correction - does have frequency shift AC Coupling

2023-11-07 Thread Jeff Clearwater via RE-wrenches
Hi Folks, Just wanted to make a correction on the EG418kPV of a statement made during the AC Coupling thread. The EG4 18kPV does have frequency shift based AC Coupling.  The confusion comes from the fact that like Sol-Ark there is a SOC set-point override feature for AC Coupling but the

Hi Dave, Yes we were one of the early adopters and installed a 32 KW Nuance system last year in CA. Mixed results though I think it's a very exciting concept and believe in it going forward - they are working out the bugs. The new version is much better execution as far as the above ground

Hi Mac and All, If you are about to do a Supply-side tap I'd encourage you to look into the many advantages of using a Feeder Tap instead - one of which is that since it's not on the load side of the Main the equipment need not be Service Rated. (not that you might not want it to be anyway.)

We've transitioned from using supply-side taps to using Feeder taps re: 705.12(B) almost exclusively. The advantages are numerous - and you just added one more - not needing line side listing on your tap hardware. One of the most dangerous things I see looming in the present code is the

Hi Esteemed Wrenchies, Love this discussion. It is clear to me after many years of watching this that the industry needs to have an Emergency Shutdown standard that includes an emergency shutdown of the BMS of every battery as well as the inverter's circuits including MPPTs if all

Hi Kris What voltage do you have your charge settings at? I recommend that bulk or absorb voltage for lithium iron phosphate not be set above 56 V - there is no reason for it even though many manufactures suggest higher settings. In cases where total storage is sized generously enough

Coming back to this Blake - seems to me you need a platform type rack that has a tilt-up set of legs. The Nuance Osprey is such a rack - though I think they only go up to 35º but I think it could be easily adapted.  They use Earth Anchors but can also be mounted to sonotubes or even ground
