  We evaluate a pre-production BACHES \'{e}chelle spectrograph in terms of its
usefulness for radial velocity surveys of binary stars with small telescopes in
a remote and autonomous. We use the Solaris-4 observatory located in Casleo,
Argentina, that is part of a global network of autonomous observatories as the
test-bed for the instrument. The setup is designed in such a way that
spectroscopy and photometry can be carried out using the same telescope without
the need to mechanically modify the imaging train. We observe single
spectroscopic standard stars as well as binary stars up to 9.75 mag. We present
results of mechanical tests of the instruments and spectroscopic observations
carried out between Nov 26th and Dec 8th 2013. We conclude that BACHES is a
very compact and capable spectrograph well suited for remote and autonomous
operation. Coupled to a 0.5-m telescope it is capable of obtaining spectra of
10 mag targets with a SNR of 20 for 30-minute exposures. This is a very good
result considering the price and size of the instrument. It brings new
possibilities to the scientific community and opens a whole new range of
research opportunities available to new and existing observatories.
