Based on SolarEdge’s HD-Wave technology, the world’s most installed residential inverter, the Genesis gives you a cost-effective solution that fits any shape of roof and any budget. It combines the traditional SolarEdge benefits such as DC-optimised production, advanced safety and long-term warranties with new levels of convenience giving you easier designs and faster installations. For systems up to 6.7kW DC (with a 5kW Genesis inverter), only one PV string is needed with just one DC isolator. That’s as simple as it gets – especially when installed with SolarEdge smart panels. As with any SolarEdge system, you’re free to design without any restrictions regarding panel type, orientation, or azimuth. Installers can continue to leverage SolarEdge’s panel-level visibility for remote system monitoring and troubleshooting, while mySolarEdge gives homeowners a Dashboard view to simply track their system production and consumption (with an external energy meter).
MS Series is GoodWe’s answer to the residential segments expanding needs. This 5-10kW Single-Phase model with 3 MPPT-s, is a powerful and versatile inverter. It is truly a champion in terms of DC oversizing, offering as much as 100%, way above the competition, making it possible as well to achieve 10% AC overloading. With a start-up voltage of only 80V, the MS is able to generate electricity earlier than equivalent products, achieving a high efficiency of 97.7%. This inverter is compatible with bifacial modules and outstandingly, as its maximum current input reaches 12.5A per string. Its light weight allows for an effortless installation.
MPPT, or Maximum Power Point Tracker, is a circuit within most new inverters which acts to optimise the energy production of your solar power system by making it operate at the most efficient voltage, ie; the maximum power point. You need multiple MPPTs if you have your solar panels mounted across multiple roof areas, and each roof area points in a different direction. This is because you each string will have different amounts of sun falling on it due to their different directions, therefore they will have different shape IV curves, and different max power points. So you need an MPPT for each string to get maximum performance from your system as a whole.
It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.
Inverter efficiency is the ratio of the usable AC output power to the sum of the DC input power and any AC input power. Typical grid-tied inverter efficiencies exceed 95% under most operating conditions. Efficiency changes as a function of AC output power, DC voltage, and sometimes inverter temperature.
Many customers ask if the inverter will be noisy, especially if installed near bedroom windows etc? The high quality inverters are usually very quiet and you will hardly be able to hear them. Cheaper models, particularly older generation inverters with transformers, are often characterised by a monotone hum and buzz, especially during periods of high output. Consider that even if installed near a bedroom window, the inverter switches off during the night. Nevertheless for shift workers etc the lesson is – buy a quality inverter and try to install the inverter near the switchboard and not direct outside the bedroom window. Suggest your preferred position to the solar system installer and also do not put the solar inverter where it is exposed to direct sun for long periods of the day.
Inverter warranties have to this point almost always been for five years. Some manufacturers like Fronius have been offering special +5 year upgrades if you register the inverter and your details with them. It is important to understand though that these bonus warranty upgrades may not cover labour or freight and may just cover the product. Still, this is good value considering a replacement 5kW inverter can set you back up to $2500 installed when a +5 bonus warranty turns this into a callout or two and some interstate freight costs.
We are starting to see some manufacturers increase their warranties to 10 years or more. For example, Enphase warrant their microinverters for 10 years and SolarEdge warrant their inverter for 12 years (SolarEdge also warrant their optimisers for an incredible 25 years)
Most manufacturers also offer upgrade options that can extend the warranty up to 10/15/20/25 years. These extensions are generally not free and may be offered at the time of the sale or the time of the installation. Additional warranties can provide good value if they are low in cost, but it is important to understand how much the price will rise.
The brand and reputation of inverter brands is really an important factor to the customers. The main criteria that qualifies a brand to be recognised is:
According to the criteria, Goodwe, Sungrow and Solaredge are the manufacturing brands has a good reputation amongst all the solar inverter brands.
Understanding the role of inverters in your home solar PV system is essential to calculating the performance, output, durability, and cost of your solar panels. The vital role played by inverters is the conversion of DC electricity into usable AC electricity.
Sungrow proudly boasts over 87 Gigawatts of Solar Products Sold across the globe. Widely recognised as being among the top World Class Solar Inverter Manufacturers. Well designed and high performing solar inverters with efficiency rates over 99%.
SolarEdge is so good because the DC optimisers optimise solar panels performance while giving users panel level monitoring. The products also have some of the best safety features to also give you peace of mind.
Solar Run recommends Goodwe when both quality and price are important. They consistently perform well in independent testing. Our Goodwe Review rates the performance, value, battery ready and the monitoring application.
We have warranty information for all the leading solar panels, inverters and battery storage systems. Solar Run also provides product reviews for all the major brands like Goodwe, Solaredge, Sungrow and more.
