Replacing two grid tied LVX6048 with a EG4-18Kpv. Going to keep the 4 SOK server rack batteries, 5kw of solar mounted to the top of the shipping container. 10kw ground mount SMA AC coupled system will be connected to the EG4-18k Generator input. Is powering a 100% electric house, and one EV.
Old System
Still a work in Progress, rushed to get online before the hurricane. Waiting on some line side taps so I can clean up the wiring and put the covers on.
Install and setup went smooth, AC coupling was very easy and worked right away after I enabled it. I installed it on a Saturday but had to wait tell signature solar was open on a Monday to call and get the customer code "Signature" so I could register it and setup the app for remote access, they should include the code in the order confirmation E-Mail so you don't have to call them.
The only problem I am having right now is I am running the batteries without comms because the manual doesn't really give any information on what comms settings to use with different brand batteries. Signature solar recommended I E-mail EG4 and ask them about it. I called current connected and they are looking into how to get the comms to work with there batteries.(current connected called me back and said I just need to change the setting on my master battery to "pylon can" , I changed the setting on master battery and the comms are working now.)
I still need to. Feed inverter with line side tap before main breaker box in shipping container than feed container and house breaker box off of inverter load output so it will all be backed up. Going to use a back feed breaker with interlock to feed main panel from inverter so I can bypass inverter if needed.
Once wiring and comms are done I will simulate a grid outage to check the transfer time, see how it does with the 2hp Well, 1hp booster pumps, 2hp air compressor and two air heat pumps. Really interested to see how the AC coupling works when grid is down. I can already tell I need more batteries to be able to run air conditioners off grid over night, will also need more solar during the winter to run the heat pumps. I will post more updates after I do more testing. (Did a quick test of a grid failure and it switched over without interruption everything stayed on and lights didn't flicker. SMA Ac coupled inverter kept working tell I turned the grid breaker back on then the SMA inverter stopped feeding for the 300 second timeout then kicked back on )
