Using a metal cabinet to store the batteries of an already built hybrid or
off-grid solar system is the most reliable and recommended option for this. The
cabinet is suitable for the installation of up to 4 batteries with a capacity of
2400 and 4800Wh, while protecting at the same time the batteries and adds
compactness and completeness to the system. The ability to lock the limits the
compromise of equipment in places with random access to people, eliminating the
possibility of accidents. Ventilation holes are provided on the housing and the
door is made of mesh steel for proper cooling of the batteries, in rooms with
temperatures from 0-50°C. In rooms with high temperatures, it is recommended to
install an additional fan, and in winter or in rooms with temperatures below
-10°? a heater to ensure optimum temperature. In the free installation method,
without using a storage cabinet, optimum temperature levels are much more
difficult to maintain and cost considerably more than the investment in it.
Ensuring the optimum working temperature of the batteries, in turn, increases
their lifetime and their mode of operation.
