Got to recabinet our Generac 21KW standby genset, the one that supplies the farmhouse with emergency standby power when the utility fails (which is frequent out here in flyover country).
When I bought the units (I have 2 of them, one 21KW propane fired unit for the farmhouse and one 35KW diesel powered unit for the shop and outbuildings that runs from the 500 gallon diesel tank that I fill the tractors from), both units came housed in powder coated steel cabinets. Over the years, the unit that powers the house has slowly but surely corroded away, leaving the internals exposed to the weather which is no good at all. The diesel powered unit has never corroded at all (glad of that).
I had to special order a new enclosure from Generac to the tune of close to 5 grand delivered. The new enclosure is powder coated aluminum, not steel and we had the remove the existing and located it in the shop, completely take out all the guts and electronics and install them in the new aluminum cabinet (which also had to be assembled) and then reset the unit on the concrete pad adjacent to the house which was quite the undertaking tp say the least.
For the life of me, I cannot understand why Generac didn't just build aluminum enclosures in the first place (like they do today) as all new units are housed in aluminum enclosures and not steel, but it is what it is.
I'm glad it's finished and back to operating correctly and the old, corroded enclosure (what was left of it) went to the scrap yard.
I considered just purchasing a new unit already housed in an aluminum enclosure but the cost of a new 21KW unit was quite a bit more than the existing one and besides, what would I do with the old perfectly operating unit? Toss it?
I also suspect that there are a ton of owners that purchased the steel cabinet units years ago that are also corroding away and will have to make the same choice I had to make, strip out the guts from the steel corroded enclosure and put them in the aluminum cabinet or buy a new unit. Tough choice considering the cost of a new one today.
