MOBILE STAND-ALONE PV GENERATOR 1.460 Wh
Mobile stand-alone PV generator 1.460 Wh was developed in cooperation with Slovenian experts and represents an
innovation worldwide. It has been developed with vision for conserving the environment by using renewable energy
sources in locations without access to electricity, improving the efficiency of public lighting, and ultimately for reducing
the costs of electricity consumption. Mobile stand-alone PV generator is ready for immediate "production" of
electricity. Unlike conventional fossil-fuel generators, the stand-alone PV generator only needs sun radiation.




In previous installations of solar panels (PV modules) in public areas, placing the batteries in the whole system was
the biggest challenge. Usually, the optimal solution would be to install the batteries underground or in the poles or
somewhere in a separate compartment. In our system, the batteries are installed in the cabinet directly under the PV
modules. Especially designed housing provides stability, ventilation and enables the inclination of photovoltaic
modules from 0° to 90°. This means that the optimum orientation of PV modules can be achieved, no matter the
location of PV generator. Therefore it is possible to achieve the optimum for maximum solar radiation throughout the
world. The stand-alone system is suitable for all public areas and locations where there is no significant shading and
direct light is falling on the PV modules.

The presented system is designed to differentiate the hot air through the housing, so that the components inside or
the PV modules does not overheat, ragardless of ambient temperature. Thus, the electronic circuits and the batteries
are protected from bad weather. It is also important to emphasize that the used batteries manufactured by
ThunderSky have a wide temperature range between -45°C to +85°C, which means that the stand-alone PV
generator is suitable for almost any climate.
Mobile stand-alone PV generator 1.460 Wh is using LiFePO4 batteries manufactured by ThunderSky. Electronics and
battery cells are mounted in housing directly under the PV modules. This elegant solution requires no additional
installation, which is usually needed in case the batteries are installed into the ground or in other separated casings.
The system contains 8 battery cells with nominal voltage of 3,2 V, 60 Ah. LiFePO4 batteries can hold up to 2000 full
charge-discharge cycles. Used battery cells have a wide temperature range between -45°C and +85°C and can
operate at temperatures where lead, NiMH and LiPo batteries fail. In addition, compared to conventional batteries,
they also have a low self-discharge. Fully charged batteries can provide continuous operation of used LED lamp up to
6 nights for 12 hours. Specific energy for LiFePO4 batteries is 90 – 110 Wh/kg (in comparison: specific energy for lead
batteries is 30 – 40 Wh/kg), which means they are lighter, plus they have a higher efficiency at charging and
maximum allowable current at discharge (to 5C, lead to 1C).

Stand-alone PV generator can be used multi-puropse, it can be designed with batteries from 30 Ah to 100 Ah and
battery pack voltage of 12 V or 24 V. It is also possible to select the solar panels of 70 W or 135 W.

Management system is composed of PV charger and battery management system (BMS), which controls charging and
discharging of battery cells and therefore prolonging the lifespan of batteries. It also regulates the battery cell-voltage
and controls switching the lamp on/off considering the lighting of surroundings (solar irradiation) and the time of the
day which we define for LED lamp to illuminate. Built-in timer allows you to set the lamp on/off switch using 46
configurable programs for each day of the week. It can also switch automatically between summer and winter time.
The main assignment of the BMS is to control charging and discharging of each individual battery cell. It has built-in
over-voltage and under-voltage protection; it provides balancing due to non-identical chemical composition of cells
and the effect of uneven aging of individual cells, etc. BMS can be connected to your PC via galvanically isolated RS-
485 connection. Especially developed software allows a wide variety of adjustable options and logging or it can also be
used for diagnostics of the system. LED indicators on top of BMS provide us with a quick overview of the cells state
and detect errors and possible deviations.

Introduced stand-alone PV generator is mobile and it can easily be transported to any location due to its weight and
dimensions. It also offers the option of upgrading the capacities of PV modules and batteries – according to the
energy needs required by certain applications.

Off-grid stand-alone PV generator is designed on the Plug&Play principle. The installation is simple: mount it on the
pole and set an appropriate angle depending on the location of installing the PV generator. All you need is a sunny
location. We expect that the Mobile stand-alone PV generator will serve in particular for applications in public areas –
for street lightning, collecting traffic data, powering weather stations, security cameras, etc.
