1. The Brief Introduction of UPS and Solar Gel Battery
The Classification of UPS
The UPS classification methods varied, according to the power size can be divided into large
and medium-sized mistress power capacity; the output waveform can be divided into square
wave, trapezoidal wave or sine wave; according to the input and output can be divided into
single phase into single-phase, three-phase to single-phase or three-phase to three-phase;
according to the work principle can also be divided into dynamic UPS and static
uninterrupted power supply two categories. Dynamic uninterruptible power supply is
dependent on inertial flywheel stored energy to maintain the load power supply continuity, the
uninterruptible power supply with heavy, large noise, low efficiency, long switching time and
other shortcomings, has been replaced by a static uninterruptable power supply. Static UPS
to batteries as the energy storage tool, city normal AC power is rectified into a DC electrical
and electrical energy stored in the batteries, when the utility power is cut off by the inverter
will be stored in the storage battery DC power into AC power to maintain power to the load.
According to the different working modes, static UPS can be divided into the backup UPS,
on-line UPS, online ups systems and Delta transformation uninterrupted power supply four
kind of types.
The Brief Introduction of Solar Gel Battery
The prime function of solar gel battery is to store the power generated from a power source
like solar rack and discharge it when the power is required. There are two popular types of
battery used for solar photovoltaic (PV) and wind turbine installations. These are called GEL
and Absorbed Glass Mat batteries and are in fact types of lead acid batteries. Both solar gel
battery and AGM They store their charge very well and do not degrade as easily as the
common lead acid battery. Because of the type of material used as the electrolyte, there is
very little chance of a hydrogen gas build up that can lead to an explosion and these
batteries do not experience corrosion. They are very safe batteries and are therefore ideally
suited to solar PV and wind turbine installations. These are well proven technologies that
have been in use for a long time. Therefore, what players offer as new batteries are modified
versions with added features, while the technology remains the same. The batteries in solar
photovoltaic systems can last up to 20 years with proper care. Most solar rack systems use a
set of deep-cycle, flooded lead-acid batteries. Each battery is essentially a box of lead plates
surrounded by battery acid, composed of distilled water and sulfuric acid.
