Once again, thanks @RCinFLA and @400bird
Proposed Setup:
New Backup Inverter: SW/B, Original Inverter: SW/A
SW/B AC OUT -->AC IN of SW/A - AC OUT -->MAINS<------ M215s. Both inverters connected to the same battery bank.
Here is what I am taking away from your comments:
1. It may be possible...
Thank you. It's certainly a possibility, but it won't increase the overall system capacity - just for those added individual breakers. Some balancing issues might be involved. One other concern is overlapping neutral/ground bonds in an inter-connected dual system (I think). It may end up being...
My system: Schneider Conext SW4024, 3kw DC coupled panels, 3kw Enphase AC coupled panels, 2 Conext MPPT 150/60 SCCs, Combox and SCP. Approx. 25kwh of batteries (20kwh of Gyll, EG4, Lifepower4 and 5kwh of refurbished BYD/TechDirect). Off-grid for 30+ years. Original SW4024 online since 2013...
RCinFLA:
Would that scenario (adding an identical unit to the AC in) work with two Schneider Conext SW4024s? Schneider has discontinued "stacking" support for the SW series. I'm already AC/DC coupled off-grid to one SW4024 - I've considered adding a discrete panel with another SW - but I like...
It does. I have been using a Combox in an Schneider SW system for almost 7 years - and it stores that data with varying degrees of detail to a usb stick. Also Very Handy for monitoring and making system changes from an ipad, computer or iphone.
I've been running off-grid AC coupled with the Schneider SW4024 and 3kw Enphase M215s (plus 3kw DC coupled panels) for over two years now. The M215's frequency shift is only slam-bang (on or off) - but it does work seamlessly, provided your battery bank is sufficiently sized to take the full...
Yes, closed loop only works with the inverter, not the CCs. With that in mind, it seems the only benefit is informational, and the ability to (perhaps) regulate charge current from an AC source according to SOC. We can already do that in open loop according to voltage. Let me know if you decide...
Fully off-grid (AC and DC coupled) for many years. In my case, I'm wondering what's been happening to my electronics:
As my batteries reach a full charge, my 3kw of old school Enphase AC coupled M215 microinverters are "turned off" by my hybrid Schneider SW4024 inverter - it does so by raising...
Could you give a little more detail on running the Gateway with two xanbus connections. I've been considering getting a Gateway - and running another SW4024 alongside my original unit (not sync-tied, but used for discrete loads and as a backup "generator" in pass/thru mode). Already maxed out my...
