Having peaked the rank for the third-largest inverter manufacturer in the world just behind Huawei and SunGrow, SolarEdge is a common name in the inverter industry for their spectacularly-designed DC optimized-based inverters and their cutting-edge technology. After embarking the journey in 2006, this Israeli new kid on the block had observed their magnificent performance in terms of sales growth by installing over 250,000 power optimizers, along with 12,000 inverters alone.
This company has 2,400 ongoing employees, and thus, being able to construct the monitoring sites globally in over 130 countries. As one of the best solar inverters Australia, other offices of SolarEdge is located in the USA, France, Japan, China, India, Germany and Australia.
Efficiency: Any residential inverter requires 95% to 98% efficiency, whereas the SolarEdge inverter has surpassed that limit by maximizing the efficiency to 99.5% ¬– the highest efficiency producer of all. This highest efficiency is achieved due to its DC optimizers set in every solar panel, which work like microinverters. Shading or any obstacle can be forfeited by the presence of this sheer amount of DC optimizers.
Warranty: SolarEdge with their highest years of warranties, 12 years for the inverters and 25 years for the power optimizers, guarantees that they are certainly the most reliable and ROI-based inverter in the world. You can claim to extend your inverters’ warranty up to 20 or 25 years – yet the longest warranty period any inverter manufacturer ever offers.
In the case of replacement of the faulty inverter or optimizer (hardly any cases though), your first installer must inspect that. However, if the whereabouts of the installer is not known, only then the company will hire an accredited and licenced installer for you to sort out your issues.
Customer Support: SolarEdge, despite showing no faults or complaints in their inverters, still tends to be proactive all the time to deal with your queries. Even during this covid-19, and storm ahead in Australia, SolarEdge is still manufacturing their inverters to meet the supply and hence undertaking various schemes to tackle your problem during this crisis. The company and its team are always ready to adapt to any changes that they have to make to satisfy the customers across Australia as their office is located in Double Bay, NSW.
From troubleshooting to online tutorial videos, along with many other comprehensive knowledge base libraries on inverters are available in their websites. Still, the customer representatives will be delighted to explain them to you verbally if you wish.
Monitoring System: SolarEdge’s inverters’ monitoring system is, in a word, “splendid.” Their inverters generally come with the standard monitoring option, but that lacks some of the important details regarding your usage. Hence, paying an extra tad of cash can get you the premium monitoring system. By using it, you can track each panel’s efficiency, their voltage, self and building consumption, data presentation at module, string and system level, and export limit.
Its graphical presentations with a lot of pictures and diagram to illustrate you the detail are ravingly awesome. You need the SolarEdge Setapp from the smartphone to use this system. Using this software, the technicians can also get an insight into your inverter’s faulty responses and act accordingly to save time and labour cost.
Battery Storage: SolarEdge has recently proclaimed its SolarEdge battery solution system at Intersolar Europe 2019, including the SolarEdge residential and larger-scale modular commercial battery storage system, which are due to be released in late 2020. Kokam, a leading Lithium battery manufacturer taken over by the SolarEdge in 2018, has been in partnership with the SolarEdge to develop a new 10kWh battery by taking the Kokam Lithium (LFP) cells into account.
These batteries are unique in design with no need for special cables. Solar energy is directly entered into the battery and has the DC-coupled system to prevent any accident from happening during outage or blackout. In fact, you don’t need any AC port to retrofit or convert AC to DC or vice versa.
Unique Feature: The great speciality of the SolarEdge inverter is its presence of individual DC optimisers. With the help of the single or multiple MPPTs, these DC optimisers boost the efficiency to a greater extent up to 99%. However, to do this, you need this inverter to run at a voltage of 380. With the individual panels’ workout and the power of the MPPTs, this inverter can generate this voltage.
However, if one or multiple panels are affected by the shading, still, the rest of the panels’ optimisers can compensate for recouping the voltage up to 380V.
Pricing: Apparently, it won’t seem apt to see a huge figure of the price of the SolarEdge inverter. Still, when you delve into comparing its latest and up-to-the-minute features, then you can realise that their asking price is fairly legit.
|Range of inverters||Estimated Price in AUS$|
|SolarEdge SEG-SE5000H 5KW||$1,200 to $1,400|
