Considering the battery investment and warranty, I was just wondering if you should have held off on buying all of your batteries at the beginning.I think buying half of them would have been plenty. Reduced capacity until the house and shop were built, but easily made up with the generator, if needed.. Plus it would give you a break of almost two years between having to replace half of them, if you split the original purchase time by two years (during house building) Having them sitting there just for the contractor's minimal use seems like a big waste, dispite saving $10K on his costs.
Course I do realize that hindsight is 20-20...
