Used, in good working condition Outback Power Solar Inverter GTFX2524 2500w 24v on-grid off-grid. It is capable of grid-tie, but you can use it in grid-interactive mode or off-grid mode and does not have to sell (disable export using the Outback Mate controller). It is used to charge battery and invert from DC (24v) to AC.
It provides a single phase at 120v. You can use two in parallel to have split phase 120v/240v (use mate to configure master/slave), or use a big outback transformer, or nothing if all you need is a single phase 120v. This is the sealed version with turbo fan - good for dusty or salty air environment. Please do your own research and make sure this is what you need. I also listed the GVFX3524 (vented version no turbo fan, so it has more power) separately, also the transformer and other stuff one by one.
But I have all the components needed to make the whole system (including Midnite ePanels - left and right, Midnite Classic 150 charger, Outback MX60 charger, combiner boxes, breakers, etc). Please note that in off-grid mode, a regular AC generator is not recommended due to the imperfect sine wave. Solar/wind and battery would be the normal combination. If you have a pure sine wave generator that produces clean sine wave within the spec, it might work as well.
