A 2,000 W or larger inverter runs the everyday loads of an off-grid cabin or a workshop: a well pump, a microwave, a coffee maker, power tools and a fridge together. Check the surge rating against your biggest motor, since a well pump or compressor can draw three to five times its running power for a moment at startup. These are inverters only; if you also want to charge the bank from the grid or a generator and switch over automatically, see the inverter-chargers.
