Putting together off-grid system for Mexico. I was thinking I would go with 2 lvx6458s from mpp solar but see a lot of people like the growatt units (6k or 8k). They seem similarly priced so am wondering if there are advantages/disadvantages to one or the other? System will be 10-12kw solar array with about 30kw lithium battery. Totally off-grid in remote location so like the redundancy of the two split phase inverters in case one goes down I can at least run system off the other one while repairing the other.
