Hi all,
I am looking for suggestions on the best way to combine TWO separate offgrid systems that both consist of a Multiplus 2 and their own separate battery banks. One Multiplus 2, let's call it MP-A has a significant solar input however the other, let's call it MP-B currently does not have any solar input so is just batteries feeding the Multiplus.
Now what I am trying to achieve is for the second system (MP-B) to receive AC from MP-A but only daily between 10am and 2pm to top up MP-B's batteries. I want this to happen automatically.
The systems are in separate buildings on a rural property 70m apart but there is already an electrical line from MP-A's output over to the building where MP-B is being installed . MP-B will supply a separate set of loads than MP-A does and the wish is for it to use it's own batteries as much as possible and as such I do not want this as a simple transfer switch arrangement at MP-B.
If I have MP-A's output fed into MP-B's input, use the ESS assistant on MP-B, and select a country code is there any chance that MP-B will fed back AC on MP-A and do damage?
Look forward to hearing your responses,
Jesse
