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] 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.
[pdf] 3 000W continuous / 6000W surge power inverter, pure sine wave output, has selectable DC 12 / 24 / 48 volts input, and AC 110/ 120/ 220/ 230/ 240 volts output, 50/ 60Hz.
