Powering the people – Inverter systems for smaller installations

At Netshield we acknowledge that not everyone can afford a mammoth renewable system, nor do they need one. Our affordable alternative energy solutions for smaller applications provide a cost-effective means for customers to remove their reliance on Eskom.

Our expanded inverter range now includes cost effective energy solutions, but we must caution that planning and understanding exactly what your specific energy objectives are, is critical to rolling out a new system. Where do you start? Ask yourself – what do I really need to keep on when my utility supply fails? Secondly, how long do I need to keep these devices powered for? Lastly, consider the expansion of your system by adding renewable solar panels to reduce your dependency even further and save on your utility bills. Click here to fill out a form to understand your energy usage and we will help you getting it lower and suggest an affordable solution.

We are well aware that SOHO offices and even homes are often the hardest hit when the power goes out, often because they don’t think they can afford a renewable energy solution. Nothing could be further from the truth, a 3KVA Inverter system like the one we are offering can help to power critical systems and keep the lights on without breaking the bank.”

The system

Our smaller bundled inverter solution is ideal for customers who don’t have high volume energy requirements, but simply need to power a small office or a home. The 3KVA and smaller inverter systems require less batteries, come in smaller battery cabinets and have direct integration into a solar array or solar panels. It is one of the most cost-effective ways by which to make use of alternative energy and supports multiple applications such as grid assisted, and generator assisted modes.

The units have a built-in solar interface, or MPPT, which means you don’t have to rely on only the grid or a generator to charge its batteries, but by directly connecting the panels to the unit you can rely on solar too. In the long term this helps bring down the total cost of ownership by reducing reliance on the power utility and/or the recurring the cost of fuel to run a generator. It can be bought outright or combined with an installation fee, where our engineers will help you scope, install and deploy the system in line with your exact requirements.

The system is perfect for customers who have identified their critical power needs and done the maths on what they need to run when the power is off and what they can live without. Smaller inverter systems are best used for critical applications, such as lights, computers and smaller appliances. It simply doesn’t make sense to try and run a kettle, washing machine and non-energy inefficient lighting on them – as this is where the cost lies.

Energy smart consumers boil water on gas, use solar geysers, have switched to LED lighting and have already purchased energy efficient appliances, making them ideal candidates for this system.

The application

The inverters, while smaller in size and scope are able to run in these applications:

Solar interactive mode – The batteries and the load are charged by the solar panels as the primary power source (when sun is available) and when the solar provenance and battery power runs out, the system automatically switches to the grid.

Grid Assisted – This is a hybrid mode and will use your solar panels and the grid connection to charge the batteries. It will always seek out the renewable feed first and switch to the grid when there is no sun, or run off the batteries when there is no sun or utility power available. Once either the sun or grid returns, the batteries and load will be fed and recharged.

Generator Assisted mode – This mode is applicable if you have no grid power but rely solely on solar panels. In the event that the solar can’t charge your batteries, or the charge runs out, it will charge the batteries from a generator and automatically switch back over to renewable when fully charged.

Power to all

We can’t stress enough how the true benefit of alternate energy supplies comes into play when consumption, usage and need is carefully and methodically calculated. Some smaller businesses have already invested in inverter systems, but have been let down by their ability, simply because the calculations have not been done properly.

Here at Netshield we work with our customers to develop a solution that matches their environment, we also advise them as to what they can and shouldn’t run on the system, as well as how to best scale the system later if their needs grow.

The solution? Our smaller 3KVA Inverter systems, provide customers with a plug-and-have-energy solution that is cost effective, can scale, and will provide them a qualified return on investment in the future as they lessen their dependence on the Eskom grid.
