Our in house designed and pre-build Solar Homes Systems are available in 2 versions:

1) 5kW/48V
2) 3kW 24V

Each system incorporates a unique all-in-one inverter/charger that is able to charge batteries from solar with the integrated MPPT solar charge regulator as well from a generator/grid connection while at the same time supplying loads with AC power. This all-in-one unit is manufactured under German quality control at an unbeatable price. Flexibility in the upgradability of the systems is a given.

Compatibility to PylonTech Lithium batteries is guaranteed.

Both systems allow for remote monitoring and supervision via an additional (not included in the system)

5kW/48V Solar Home System
This Solar Home System is designed to power medium to large houses excluding any workshop and consists of the following components:

a) Solar Home Board 5kW/48V
b) 8x PV Modules
c) 8x 12V AGM Batteries
d) Mounting accessories and manuals

The client can either choose between AGM maintenance free 12V batteries or lithium batteries.

The above configuration allows the connection of the following loads:

Adding additional loads to the system requires addition PV modules as well as an increase in battery capacity.

3kW/24V Small Solar Home System
This system is designed to cater for a small to medium home and consists of the following components:

a) Solar Home Board 3kW/24V
b) 4x PV Modules
c) 4x 12V AGM Batteries
d) Mounting accessories and manuals

Although compatibility to PylonTech lithium batteries is given, system upgradeability is limited as only one PylonTech battery model is suitable to be connected to the system. The maximum number of PylonTech batteries that can be connected is limited to 6 (12kWh) while AGM batteries can be expanded to 10 (24kWh).

The above configuration is designed to cater for the following loads:

Adding additional loads to the system requires addition PV modules as well as an increase in battery capacity.

PV Modules

PV modules are the heart of any solar electric system. They convert the visible sunlight into electrical energy.

Inverter

Inverter converter DC energy obtained from PV modules or batteries into AC energy that normal household equipment uses. High efficiency inverters are a must to efficiently convert the limited available energy form DC to AC.

Batteries

Batteries are used to store energy for night time usage. Different battery technologies are available on the market with a large variety of application. Lithium is one of these technologies which is rapidly expanding the footprint worldwide.

Pre-assembled solar home systems for every day use

Accessories

Accessories such as remote monitoring devices or system displays are available from us for all our products we supply in the solar sector be it SMA, Victron, Fronius or Phocos.

Supply and Installation of Laundry Equipment at Katima Mulilo State Hospital

Ministry Of Health And Social Services

2011

CTS was awarded the tender in July 2011 for Katima Mulilo’s Hospital laundry. The scope of the work included the supply, manufacture and assembly, delivery to site, installation, testing, commissioning and maintenance of laundry equipment.

Safety is born of experience. In the field of clinical practice, medical know-how and professional laundry care ensure optimum treatment and care of patients. For this, systematic cleaning, disinfection, drying and sterilization of linen and operating garments are prerequisites for avoiding risk to both patients and staff.

Katima Mulilo’s Hospital has to process over 1 ton of laundry per day. Our high speed washer extractors have a spin factor of 830rpm, greatly reducing tumbling time. With built in soap dispensers, the correct amount of soap is used each time, and the perforated lifting ribs mean more mechanical action and lower water consumption. The high speed washers significantly reduce water and electricity consumption, and still ensure hygienically clean laundry.

Miele offer rotary ironers with roller diameters ranging from 210 to 500 mm. Aluminium heater plates instead of steel guarantee an excellent distribution of heat and considerably reduced heating up times. The foot control ensures that the roller can be easily stopped, eg. for steaming.

A pneumatic lifting device creates a high pressure ironing action for an excellent finish. Katima Mulilo’s Hospital has the largest Miele rotary ironers in Namibia.

Oranjemund Airport - Supply, Install and Commission of an Aviation Weather Monitoring System

DeBeers Marine Namibia

2015

DeBeers Namibia published a tender for the supply and installation of a weather monitoring system at the Oranjemund Airport. CTS was awarded the tender based on price, knowledge of the meteorological measuring equipment as well as quality of products. At time of installation the station was the most advanced aviation weather station in Namibia.

Technical Details of the system installed:

Ceilometer at end of runway 20 to measure cloud height at three levels up to 7,500m
Runway Visibility and Present Weather sensor at stop end of runway 20.
Present weather sensor monitors 7 different types of precipitation
visibility sensor takes background luminescence into account
Wind speed and direction a touchdown runway 20.
Wind speed and direction, rain as well as barometric pressure at stop end runway 20
AviMet server for processing of all data
3 workstations spread along the buildings for weather monitoring and supervision purposes
ATIS voice system transmitting on aviation frequency as well as telephone dial in the current weather conditions

All communication between the equipment and the AviMet server is based on wireless transmission to reduce cabling costs.

The weather information can be picked up rough 100 NM away from the airport by all approaching aircraft.

Quality Tyres Namibia

2018

A 200kW PV peak grid tied PV system was installed at Quality Tyres Lafrenz Industrial Area. Remote monitoring of all 10 inverter allows for early fault detection and system degradation as well as maintenance planing.

System Specifications are:

680x 295W Canadian Solar modules
10x Fronius Symo 20.0-3 Grid Inverter
Roof mounting structure for IBR roof sheeting
AC surge protection
configured for remote monitoring

Containerized off-grid solar solution for the Omusati Region

Ministry of Mines and Energy

2013

CTS was awarded the first ever containerized off-grid solar electrification tender for the Ministry of Mines and Energy beginning of 2013. This project entailed:

Upgrading of all government building wiring as per national standard for 9 sites in the Omusati region
Manufacture, supply and install container power units for these sites.

The power containers consisted of ca 2.8kW of PV modules installed on the roof as well as 3,000 to 4,500 Ah of battery capacity depending on site requirements. Five KVA inverter charger and two 70A Blue Solar Charge regulator all from Victron Energy complete the system.

With a total of nine containers, school, hostels and other government buildings were electrified. Each container was subdivided into two rooms for batteries and inverter technology respectively.

With our 36T/m crane truck CTS was able to transport the container to site, navigating through thick sand with ease.

Installation of 4 Containerized off-grid PV systems in the Otjozondjupa Region

Ministry of Mines and Energy

2019

Central Technical Supplies was once again awarded the tender to electrify 4 remote localities in the Otjozondjupa Region of Namibia. Custom build containers where installed on site with SMA Sunny Island 8.0 inverter installed. In addition the offered lead acid battery technology has been replaced by state of the art lithium batteries reducing system maintenance. The use of AC coupled technology did allow for the SunnyBoy solar inverter to be in installed inside relevant buildings on which PV modules are mounted. All components are interlinked by means of wireless technology to allow for remote monitoring where GSM signal is of sufficient strength. System sizes vary form 3kW, 12kW, 15kW to 20kW of PV power while inverters are as much as 3 in a single phase cluster.

Sites that were electrified are:

Nhoma
Aasvoel Nes
Kanovlei
Grashoek
