What is the Best Solar Inverter to Buy in 2019?


Hello solar enthusiasts! Have you been wondering which inverter to
use on your upcoming solar project? If so then this next video is for you! Intro

the inverters that do all of the work in the solar energy system. Central string inverters that came with solar
systems of the past, let’s say up until 2018 used to manage the conversion of DC to
Ac voltage that you can use I your house for the entire solar system. That meant if one panel went down because
of shading or mechanical issue, the entire system would not produce very effectively. Then microinverters were developed out of
Fremont, California by a company called Enphase. These guys were working on the central string
inverters for a big company until they decided to go out on their own and figure out a way
to make n inverter that would convert the energy produced by the panel into usable AC
voltage for your house. Nobody else is doing this, and it’s really
thrown the central string inverter companies for a big loop because these new inverters
are warrantied for 25 years instead of 10 years. The undeniably best thing about Enphase is
their inverters are double insulated and small enough to be placed at each individual panel. NOW each panel has its own inverter and if
a panel goes down because of shading or some mechanical, then just that panel goes down. All your other panels will continue producing
clean energy for you. These microinverters are UL Listed relating
to voltage and frequency, synchronization, disturbances, faults, and reconnect time. This UL Listing ensures that your grid direct
system meets IEEE 1547.1-2005 which specifies the type, production, and commissioning tests
that have to be performed on these microinverters. To me it’s so interesting how one company
can change the composition of an entire field like Enphase has done with solar. The old DC inverter companies are now trying
to play catch up. The way they are duplicating Enphase technology
is by creating these “DC optimizers” at each panel acting just like a microinverter
in the way that allows the rest of the your solar system work even if one or two panel
goes down. They had to! I was talking to my territory manager who
gets me my solar parts and equipment in Sacramento and he said his top 3 grossing solar companies
all use Enphase microinverters. DC inverters were getting dropped quickly
as outdated technology. Happens all the time… Fox Family installs Enphase microinverters
because they are the best technology for today’s quality driven customer. The price comes out to be the same. The industry did a good job of pricing them
similarly. We also use Quickmount PV flashings and racking. I’ll leave a link to Enphase and Quickmount
PV in the space below here if you want to go visit them. Both companies are engineered right here in
California. They are produced in China, but there isn’t
one inverter company manufacturing their own inverters here in the US, unfortunately. I’ll have a video about Quickmount PV flashings
soon as I’m super excited to be using the industry’s most weatherproof flashings to
mount your new panels on! Okay, just to geek out a little bit, I wanted
to point out a couple of things I really like a bout Enphase microinverters? Probably the most important is since they
are located right at each panel, the maximum power point (MPP) of each module is tracked
and sent to your monitoring app on your phone. Enphase’s is called Enlighten. I’ll have a video out soon about Enlighten
and the cool features it has like monitoring your production. Of course we already talked about how Shading only affects those modules, not the
whole system. The Solar panels can be installed at different
angles and azimuth orientations unlike central string inverters that require all the modules
in each source circuit to be at the same tilt and orientation. We’re not running high voltage DC circuits
through your attic or across your rooftop. We are running AC voltage instead. You know how your central string inverter
is probably gonna go out after 10 years right? If one microinverter were to go down before
its 25 year warranty, the rest of the system keeps producing lowering your down time, lowering
your production time. ☹ Sad face… If you’d like to see Fox Family installing
one of our recent projects, I’ll place a card up above here and you can see us in action. If this is your first time visiting Fox Family

project.

  1. Guy Marsden has been using the individual inverters since 2010 and has realtime web connected interfaces on his website. Clearly the shading advantage is considerably more important than the warranty argument. Once people realize that conventional setups lose power from all panels just because one panel is in shade, they appreciate having individual inverters. It is one of those logical designs that was only limited by cost in the past. The current downsides include difficult access when each inverter is mounted directly under a panel that is often sandwiched between other panels up, down, left and right. Clearly environmental exposure may be a concern without incremental cooling. Marsden has experienced recent failures requiring removal of extra panels, not great if the owner is paying labor. But the power advantage is real. Perhaps thoughtful remote placement of the inverters needed for the middle of the array should be considered. It would seem the advantage of individual inverters could still be achieved even if the electronics were mounted inside and dc connected to the panels. I suspect future generations will further optimize maintenance and cooling capabilities as well. https://www.arttec.net/SolarPower/index.htm

  2. We just took a look at Dean Sanders home located on the Mokelummne River just down steam of lake Commance I Installed 20 panels there ground mount back in 2015…the home run was over 500 feet from the meter,so we used a string Inverter in this case…but on my bosses house we used Enphase for his 65 panel roof

  3. Yup got Enphase under my panel's, yes it has 25 year warrant, but i dont they're anyone who had there system for that long yet in my area. Hope it last longer.

  4. in first excuse me for my english .Hello I am from Algeria North Africa I am in the field of cold and air conditioning for 24 years, and I really find you are great, professional and slender in your job felicitation I am honored to follow you I still learn and I rediscover this trade with you, thank you I remain faithful to you.

  5. THIS ADVERTS FOR ENFASE HAS LOT OF LIES. TO GET 10 MICROINVERTERS AND HAVE TO REPLASE 5 IN THE WARRANTY, THE LABOR COST WHICH IS NOT COVERED IN VARANTY WILL BE MORE THAN CHANGE STRING INVERTER. MOST OF THE STRING INVERTER HAS 2 mppt CONTROLER AND CAN MANAGE 2 DIFFERENT PANEL GROUP. YOU HAVE TO PAY 500 DOLAR EXTRA FOR MONITORING THE MICROINVERTER TO HAVE THEM CONECTED TO INTERNET, ALL STRING INVETRER HAS WIFI WITH FREE MONITORING. YOU SAY CHANGE MICROINVERTER ON THE ROOF IS EASIER THAN STRING DOWNSTAIRS IN THE HOUSE??? NICE JOKE.

  6. im totally off grid and i thought you were gonna talk about inverters in general i dont care much about micro inverters

  7. From my knowledge With enphase inverters you cant go off grid and store batteries since they put out straight AC current. So that system is suitable for selling power to the grid and using it when the sun only shines.

  8. What's the price difference between string and micro inverters? In Australia micros are pointless given that they are 20% plus more.They are good for medium shading but pretty pointless if you have good sun coverage

  9. Fair bit of misinformation here. String inverter can be used on multiple orientations and assuming that a string won't last past 10 years is pretty silly.There are pros and cons to both.Like for like string to enphase the difference is only 8% and given they are a lot more to purchase its pretty pointless
