Schneider XW+ 6848 grid tie testing?
After reviewing the Schneider XW+ install manual (pg 3-30 OR page 78 of 174) looks like I am going to need two separate cables to hook up my Shipping Containerized Solar System to the home I am testing/ commissioning it on and since it is sitting over 100 feet away, 60 amp rated cable is going to get very expensive! I may have to consider moving the Container closer to the home which can be done but is less than ideal since the home is on the side of a mountain and it takes time and money to relocate.
My goal is to have any and all excess solar energy generated sent to the home to offset the homes loads, however I do not want the batteries to be used at all, unless of course I manually configure that to happen. I'll use the Sun to keep the batteries healthy and happy, and also the grid will be there (as there is no generator yet installed) to charge/ equalize batteries every 3 months or as is required if there is no Sun.
Since I am only testing the System I don't need it to function fully as a Grid Tied System does and as such am hoping there may be a way to only run 1 cable to the home from the load side of the 60 amp breakers in the PDP. I figure that when I need to top up the batteries in the cloudy winter months I can connect the single line feeding the home to the grid input side of the 60 amp breaker and charge from the grid. Kind of a pain in the but don't yet see why it would not work?
I guess the system would be utilized in an "off grid" type situation and I would only use the grid to maintain batteries as necessary. Is it possible to do this without pulling any power from the battery bank and only "sell" or push power to the home when the sun is shinning.
Another concern that might make my idea not feasible is the "Islanding" Issue. If the grid is down I would still be supplying solar power to the home which is not an option...... For the inverter to shut down with a grid down situation, It may need to hooked up with the two cables - one feeding the container grid in and one feeding the home....
I'm sure I will figure all this out as I move forward with this project, but thought I'd post this to gain any insight that may be avail through members with experience with this type of situation. Appreciate the forum and the time members put in.
