MOSCET’S range of solutions

MOSCET offers a range of renewable energy and power protection systems to suit all customer needs and requirements.

Uninterrupted Power Supply Systems

UPS or uninterruptible power supply, is a power supply that includes a battery to maintain power in the event of a power outage. Typically, a UPS keeps a computer, plant or electrical equipment running for several minutes or hours after a power outage.

The standby UPS ensures that the inverter is energised when the input power fails, which opens the transfer switch. The transformer provides limited voltage regulation and output waveform “shaping” The isolation from AC power transients provided by the transformer is as good as, or better than any filter available.

The double conversion on-line UPS is the most common type of UPS above 10kVA (Volt-Ampere). Double Conversion On-Line UPS is the same as the Standby UPS except that the primary power path is the inverter instead of the AC mains.

In the design of Double Conversion On-Line operation, failure of the input AC does not cause activation of the transfer switch, because the input AC is not the primary source, but is rather the backup source. Therefore, during an input AC power failure, on line operation results in no transfer time. The on line mode of operation exhibits a transfer time when the power from the primary battery charger/battery/inverter power path fails.

Solar Energy Systems

Solar energy systems use less electricity and dependency on the grid as well as reducing our environmental impact.  Solar Power is the conversion of sunlight into electricity using Photovoltaics (PV). For smaller systems, this energy can be stored in a battery. The energy stored in a battery can either be used as direct current (DC), or it can be converted to alternating current (AC) by an inverter.

Wind Energy Systems

Wind moving at certain speeds possesses energy. The energy in wind can be converted into useful energy in the form of electricity by wind turbines. Large windfarms consist of consist of hundreds of individual wind turbines which are connected to the electricity transmission network. Smaller wind turbines can also be used for households, schools clinics and community needs.

Solar Water Heating Systems

Solar water heating systems include solar geysers.  For an average household, 30% to 40% of the monthly electricity bill goes to water heating. Our solar water heating systems use heat from the sun to heat domestic water.The benefits of using solar geysers are namely:

  • Cut your electricity bills: Sunlight is free, so once you’ve paid for the initial installation your hot water costs will reduce.
  • Cut your carbon footprint: solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.
  • Investment: Installing a solar water heating system increases the value of your property.
  • Independence: You get free hot water even during blackouts and erratic power supply.

High Pressure Solar Geyser

Solar power geysers together with a high pressure system are best suited for your everyday household. Very basic and reliable systems that ensure continued supply of hot water.

The water in the tubes is directly heated by UV rays from sun. Water pressure depends on the pressure present at the premises. No booster pump is necessary for this model of geyser. This product is available in 100L, 150L, 200L and 300L.

Low Pressure Solar Geyser

A low pressure solar geyser (also referred to as a close coupled unit) is popular for many reasons due firstly to the solar power aspect. There is no need for any external electricity sources.  Secondly, it is a very basic setup. To heat water on a daily basis all that is required is the sun’s radiation. These systems are also popular due to the fact that there are no moving parts involved which maintains the simplicity of the system.

Like the pressurised system, water in the tubes is heated directly by the UV rays of the sun. In this system, water pressure depends on gravity. A booster pump may be necessary where stronger pressure is desired. This product is available in 100L, 150L, 200L, 300L and 350L.

Split System

For this system the tank is installed on the wall of the premises or in the ceiling if desired. This product is available in 150L and 200L sizes.

Renewable Energy Systems

Renewable energy sources are clean energy. With the global concerns of climate change, rising electricity prices and rising demand for electricity, renewable energy sources offer a viable option for energy production.

Grid Tie Systems

Take advantage of the energy from the sun during the day to reduce the cost of electricity. A grid tie system is connected to the electricity grid of your house. This means during the day energy is used is free from the sun.

Grid tie systems consist of only 2 key components – solar panels and a dedicated grid tied inverter. All the electric power generated by the solar panels feeds through a mains synchronized inverter directly into your distribution board and offsets the power you would normally consume from your electricity distributor.

It will of course only do this when the sun shines! If the panels produce more power than what is being consumed at the time, the balance will flow back into the network and it will actually reverse the electricity meter (not all types of meters can do this though). Since no batteries are used, no independent energy can be stored for later use. This means that energy required at night will still be obtained from your electricity provider.

Using actual figures will explain this better: Let’s assume the typical daily consumption of a building is 30 kWh, over a 24 hour period. If the solar array can produce the 30 kWh during sun hours, a substantial amount of this energy will be flowing back into network and the meter will be turning backwards during this period, building up “credits”. At night, energy will be obtained from the network and the meter will turn forward again, using the “credits”.

If we get the balance right, the meter will show zero usage at the end of the 24 hour period! If our consumption were to increase to 40 units per 24 hour day, we would still get 30 units for free from the solar system and we will only buy the remaining 10 units from the network. If we only consume 20 kWh, we would have “exported” 10 kWh. Since we have now become a power producer, this electricity could theoretically be sold to the network.

The functionality of grid tied systems is such that they will only operate in the presence of an active grid network. If a power failure occurs, they will immediately shut down. This is a legally required safety feature to ensure that the electrocution of workers possibly working on the network cables cannot take place. Since no backup energy is stored in a battery bank, no electricity will be available whilst the power is off.

Hydro Energy Systems

Moving water or water that is stored on higher ground possesses energy. This energy can be converted to useful electricity by a turbine and then fed into the transmission network

As the leaders in renewable energy in Lesotho, we start with assessing requirement for each project in order to bring tailor made solution to the satisfaction of our clients.

Off-Grid Systems

Where an electricity provider is either not available or too expensive, the Moscet off-grid solution provides the ability to generate reliable power, reduce cost and minimize inconvenience.

The off-grid solution involves power generation through wind turbines and combined in hybrid systems with a solar panel.

A battery bank is supplied which is used to store electricity for periods of lower power generation and a power management system which protects and manages the devices while providing stable electricity as and when required.  These systems have recommended maintenance guides and a service team is available to assist with installations and any customer concerns.

The off-grid solution provides energy solutions from stand alone household lighting to off-grid power for rural communities.

Wind turbine options range from 600w, 800w, 1kW and 3kW system and is also available with maximum power point tracking charge controllers (MPPT).

Solar Street and Security Lights

With electricity costs rising and the constant need to control costs, solar lighting is the obvious choice.  Solar street lights are compactly designed and easy to mount.

Solar security lights can be Installed in front of steps, entrance doors, patios, garbage can areas, etc for optimum effect.

Mini Grid Systems

Mini Grid / Decentralized systems can be supplied from different sources of renewable energy. The source of electricity may be solar, wind or hydro. Ownership of the systems depend on the business model applied when implementing decentralised systems.

Mini Grids / Decentralised systems are ideal in isolated areas where the grid connection is difficult or not cost-effective, mini-grids/decentralised community systems are necessary.  The advantages are the low cost of energy supply, scalability, ease of addition of other energy sources like hydro or wind.

We design and install mini-grids focusing mainly on the technical, social, administrative and financial aspects in order to bring the sustainable models to customers and communities.

A community based model can be applied for where the community becomes the owner and operator of the hardware. In the case where profound knowledge and more capital is required, the private sector model can be applied. The private sector will own and operate the hardware.

A hybrid model can also be applied in which all other models are combined to benefit from the advantages of each of the models and to minimise shortcomings.
