GO GREEN – INTELLIGENTLY



Projects Completed

 

8000 Watt Installation in Hartbeespoort, South Africa.
36 x 210W PV Panels, 18KVA 3-Phase Inverter, 1660 Ah 48VDC Battery bank.

 

 

45,400 kWh Solar Energy per day. Installation in SKEERPOORT, South Africa.42 x 180W PV
Panels, 15KVA 3-Phase SMA Inverters, 1660 Ah 48VDC Battery bank. 6 X 200 Liter Solar
Geyser.





We have installed 60/120Kw of 3-Phase SMA inverters, 4 x 48V 1050Ahr Battery banks for 3
days autonomy and 35KW of PV Panels (210kWhr/d) to provide power to the two office
buildings. The offices will consume about 60 KWh hour of energy per day.
Central Airconditioners and external lights gets power from the grid.

 


The above picture is of a site at Nuarro Mozambique. 100Km south of Pemba.
They combined the use of a 40KVA generator with 36/72KW of inverter and 10 KW of PV to provide power to the Resort. We added and additional 3KW wind turbine to provide additional power in the evenings. The resort consumes about 80KW hour of energy per day. This low consumption is achieved via efficient lighting and AAA rated appliances, natural ventilation energy efficient building techniques and solar geysers.

The solution is balanced so that the generator only runs for 2 hours per day during peak season and not all during low season.

 

 



37,800 kWhr Solar Energy per day. Installation in SKEERPOORT, South Africa. 30 x 210W PV Panels, 10KVA Single Phase SMA Inverters, 1050 Ah 48VDC Battery bank.

 

 
CCTV Wireless Repeater Site at Madupi Powerstation (ESKOM), Lephalale.
1050 Watt of Solar Panels, 1kW Pure Sine wave Inverter, 630 Ahr 24VDC battery bank and Equipment Shelter.
As part of this project we have also supplied the 45meter Lattice Mast with all civil works.
 

Mobile Wireless/Cellular Outstations, at Madupi Powerstation (ESKOM), Lephalale.
We did the complete project of Solar Panels, 1kW Pure Sine wave Inverter, 525 Ahr 24VDC battery bank and Mobile Telco Container.
As park of this project we also supplied the 12m Lockable Telescopic Mast that can handle a mast load of 64g.
