Guarantee.

Manufacturer guarantees are interesting when selecting an inverter technology. More commonly is a complimentary extension to base guarantee options in recent years. As guarantee obligations can often be shielded by installer incompetence, should a manufacturer define an adequately trained installer network with a complimentary warranty extension (added end-user benefit), such guarantee has been considered as a base warranty more likely of adhering manufacturer installation specifications.

  1. This comparison is not performed using the proper methodology and thus falsely gives the advantage to SolarEdge HD-Wave. The Enphase inverter works best with the IQ7+ using a 340-400W 72-cell panel that can be used on residential applications such as a 5kW system. In this scenario, the LCOE of the Enphase is far better than SolarEdge HD-Wave. In addition the software monitoring and remote diagnostics are far better with the Enphase than SolarEdge giving the product a better asset management capability.

    • What is “the proper methodology”? The comparison, in this case, is the Solar Review Assessment Criteria which is available for consumers to review and decide what is and is not important to their unique scenario. It is great that you have a select product combination where a solution works best for your clientele – Afterall one solar product doesn’t fit all. The downside to your ideal product combination is this solution doesn’t quite match a diverse array of installation scenarios.

  2. It’s doesn’t even give the correct info on the warranty for enphase iq7. On the enphase website it says 25 years. On this completely false review it states 10 years. What makes you think that any other specs it shows for both products to be correct?

    • In the U.S you are correct. Solar Review though is an international site and compares international specifications. Alternative countries where Enphase micro-inverters are subjected to potentially more testing environments, the product warranty is 10-years. As a standard, Solar Review compares international specifications only. Every technology should be considered on its own merits locally. This site has never stated otherwise. Isn’t it nice to know a world exists beyond American borders where other people may also consider solar energy?

      • In The Netherlands (so Europe) the warranty on Enphase is also the by Leonel mentioned 25 years.
        In addition to your comparison I’d like to mention the extra flexibility of Enphase with the possibility to extend the system with extra panels in the future. More need for power, for example because of buying an electric car? Then more panels within the same system.

      • You should then specify that. When you post 10 years, you would need to specify 10 or 25 years depending on territory. You also forgot to mention that solaredge wave inverters have a fragmented warranty depending on the parts the inverter system refers to. You also forgot to mention that in some other countries solaredge on their warranty document states that in some countries, it is only limited to 7 years. This looks like a very biased, and misinformed website paid by solaredge. I don’t see any objective reviews about it. Also if you look at both data sheets, the solaredge inverters have fans built in. It states natural convection which mostly refers to fans keeping the inverter cool. Good thing though is that the fans are not THAT loud since max db rating is 25. With enphase, there are no fans or moving parts with the enphase microinverters.
