WZELB makes a very good 36-volt inverter. It comes with cables, a replacement fuse, and numerous safety features, such as overload, overvoltage, short circuit shutdowns, etc. This inverter is flexible and easy.
[pdf] DC to Variable AC Conversion: Converts DC power back into AC with adjustable frequency (0–250 Hz). Operation Benefits: Rated motor torque is available at low speeds. Starting current is significantly reduced, typically between 0.5 and 1.5 times the rated current.
[pdf] The proposed inverter provides step-up and step-down operation in a single stage with a wide range of input voltage. It is implemented with a single output inductor, a high-frequency transformer for isolation and only one switch is switching at high-frequency at a time.
