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

CTS has electrified two schools in remote northern Namibia funded by the Hanns Seidel Foundation with the aim to provide electricity for lighting, thus extending learning hours for learners well into the night. Both systems are based on BlueNova 4kWh lithium ion batteries, Victron Energy charge regulators and inverter technology. Remote monitoring is possible via the integrated Colour Control GX from Victron. Special attention has been given to the system configuration to prevent total battery shutdown. This is achieved by switching the inverter off at a predefined battery state of charge (typically 20%) and only reactivate the inverter once the batteries are charged beyond a predetermined threshold.

The systems where officially inaugurated by the Ambassador of Germany in June 2018.

The installed photovoltaic system at Elavi Clinic caters for the power supply to the clinic as well as the nurse houses. A 6.2kW PV module array generates enough power for the energy requirements. Should this not be sufficient the batteries can be charged by a backup generator.

The system consists of the following:

• 6.24 kW PV array
• 2x Victron BueSolar 150V/70A MPPT regulator
• 600Ah Battery capacity
• Inverter/Charger, Victron Multi, 48V/8000VA
• System Monitoring (BMV700, Color Control GX)

CTS was instructed to supply, deliver, install, test and commission laundry equipment for the Mine Complex Change House, Plant Complex Change House and the FPR Change House at the Husab Mine in 2015.

The Husab mine has to process nearly 2 000 overalls and towels on a daily basis. Emphasis was made on equipment that is energy efficient, safe to operate and cost effective to maintain.

Miele equipment fulfills every requirement when it comes to the economical processing of large amounts of laundry. Miele’s tried and tested programs ensure the correct washing process for every type of material. The tumble driers complement the washer extractors and are highly economical, thanks to short running times. Thus you have a perfect solution to process large amounts of laundry, fast, hygienically and economically.

CTS installed washer extractors fitted with water recovery units and heat pump tumble driers. Laundry-care requirements vary significantly according to the customer’s needs. Whichever your requirement, CTS can offer you the ideal solution.

This is a typical photovoltaic (PV) medium scale farm system found on many farms around Namibia. Over the past three years this system grew in PV size from 350Wpeak to ~1200Wpeak.

System specs are:

• PV modules with a total capacity of 1220Wpeak
• 1200VA, 24V Inverter charger
• 40A Solar Charge Regulator
• 360Ah battery bank@24V
• Battery Monitor showing: state of charge (%), charging/discharging current (A), Battery Voltage (V) and time to go (h)
• Switchgear for submersible pump control

The PV modules are mounted on frames facing true north for optimal energy harvesting. During times of limited sunshine, especially the rainy season, battery charging can be increased by starting the generator. Should the AC load increase behind the inverter rating, the generator can support the system to cater for the increased load. No automatic generator start function is included.

Furthermore a second PV system for the Farm workers has been installed to cater for lighting and a TV.

• 2x 90Wpeak PV modules
• 20A Solar Charge Regulator
• 2x 105Ah batteries
• 350VA, 12V inverter

CTS removed old and obsolete laundry equipment and installed new machines.

The installed equipment consisted of:

1. 2 x new Primus FS40 high speed washer extractors
2. 2 x Maytag energy saving tumble dryers
3. 1 x Miele through-feed drying ironers
4. inculding laundry trolleys, ironing trolleys and other small accessories
