I only have Hoymiles converters never had a problem now the over heating of my 1500 model I resolved with a 10 $ Fan whitch is connected to a temperature switch , problem resolved !! Now I’ll buy the 2000 model whitch can handel 4 panels of up to 680w each ! Not bad !

Thanks Mark for a thorough and insightful review.

Hi Mark, loving your vids. Can you explain what you class as "heavy shade" please? We have full sun from 10:30am -3pm in the summer but shaded by trees at all other times. Not sure whether to go microinverter or string inverter????

Amazing how successful Enphase Microinverters are around the world. Several companies only!! install Enphase Microinverters here in Australia.

about the pricing hoymiles is like almost 40 to 50% cheaper, it is also interesting that can you share the 6months of the testing, how about the generation power between two brands in the same conditions? is that a lot of different?

​@@markcavanagh 5% is way too much, i also would like to know where is it come from. For distributors, before choose a brand, they might need to think about the product reliability and also concern the profit and cost-effective which is also hoymiles pursue. about the DTU warranty we will make a change from 2022. your video is very great that we do thankful about what you comment, enphase product is great and also it is what we are trying to get close.

Trying the hoymiles for the house but cheating a bit. Have a central location for my inverters so access is better and can ensure good ventilation and some shading. Got to do a bit more research but looking at the 1600 watt micro in with 3 of them running in series.

What about AP Systems Microinverters? I've had good success with those with just a few failures on over 30 installations. Do you have any data about how they handle split cell panels? I mean, how is their MPPT tracking algorithm?

Hi Mark, thanks for your detailed comparison, whenever you do the AFCI video please share some details with us about the importance of the distance of the DC circuit, since I´ve heard that manufacturers say that the closer the better for the AFCI efficacy since with longer wires noise can build up in wires and confuse the AFCI or make it numb for arcs but they lack to share a distance / efficacy graph or guide. Thanks again !

Just upgraded 11 yo solar to LG/Enphase. I do like the panel monitoring, but Enlighten is very light on information. I agree, an instantaneous power meter should be standard in Enlighten, as too, additional basic information like array size, temps, voltage etc. My old Aurora inverter was able to display instantaneous power production, why not Enphase? My new system did not need micros, but for me, it was a personal choice. The IQ8 family of micros will have models to suit multi panel connection.

Well depending on the electronics quality 70c isn't an issues, even 100c can be no problem if the components are of good quality - so that a relatively mood point without doing a teardown and look what is actually inside

Mark, it seems a lot of your discomfort with Hoymiles is that they have not proven themselves over time. I'd rather you say that than give a slanted review. Also, should have highlighted some benefits (at least in the US) of Hoymiles: max continuous power of 480W (HMS-2000-4T-NA) versus 380W for Enphase (IQ8H-240), and higher branch circuit current with 10AWG than the smaller 12AWG used with Enphase. Unsure if I will choose Hoymiles or not, but I'm very glad Enphase has a strong competitor to push them especially in for support of the new higher power panels.

My bigger concern was the temperature it was running at. But the fact that they have not proven themselves over time is also a legitimate concern given they run so hot. But, each to their own.

@@mcelectrical Who cares if the inverter runs 10C hotter, if it is built to handle it and still performs. You're still saying that you expect them to fail. My first install with Enphase had 3 of 18 inverters fail in the first five years (certainly they have improved or they would be out of business). If you read Hoymiles documents, they say they expect the 4-in-1 inverters to run hotter due to the higher energy densities and have built them accordingly, including derating the output at extreme temps. So, you are either saying you are unaware of Hoymiles design (search hoymiles high temperature) or you don't believe them.

Thank you for the very informative video, great review. I have been wondering how Hoymiles perform in-field ever since I started seeing their content online this past year. Regarding the warranty documents and Australian Consumer Law: I think a lot of these PV manufacturers try to write as few warranty documents as possible (one document per series of micro inverter or product) and since Australia is one of several global markets they may not be required to cover labor in other parts of the world? But as you correctly pointed out, our consumer laws here supersede these warranty obligations.

​@@markcavanagh Yes you are 100% right. Lawyers are expensive and bill by the 15min. Lawyers write/review the warranty docs. I used to work at Q CELLS and Solar Edge, both their legal teams are based overseas (Korea and Israel HQs). Getting them to write anything, would take a while and have to go through several layers of approval before they could even see it. Local/Aussie engineering teams advise the lawyers who edit the final versions that get published

One more point I heared of: hoymiles make it Easier to add batteries.

An Internet connection is required? This is news to me. A warranty requirement for a continuous Internet seems ridiculous to me. No real-time monitoring system should require this. Especially for a piece of power electronics. Who else requires this? I am going to keep this in mind as I continue to evaluate solar options.

Great review. Looking at the tech specs Hoymiles look relatively decent, but your test results on operating temp worry me greatly.

Hey Brandon, the temps shouldn't, I've installed many Hoymiles Systems and they operate fantastically even in high heat, where I am in Alberta Canada we saw temps exceeding 40C with R-Humidity exceeding 90% and the HM 1500NT only reached an operating temperature of 49.1C which is well below the thermal degradation point of electronics (80C), they actually have the lowest failure rate of all inverters in the entire industry! I've used them on systems from as small as a 8 panel 3kW system all the way up to a 396 panel 146kW ground mount system. They kick the ever living crap out of enphase for price, quality, and longevity which has been a huge issue with enphase this past year.

In the USA it comes standard as 25 years. In Austria it is 10 years. I’d hazard a guess it it because Australian Consumer law is stricter about warranties and Enphase has to also pay for labour to replace the unit.

Can't be true that there can be difference on shaded solar panels and power produced based on microinverter manufacture. The same electrical rules for both and if panels used for tests are the same, results should be almost the same for any of microinverter. The only difference is solar electrical production start current that is different on model basis.
