Yes, wait to buy your spare. I did not have a bad one for 4 and 1/2 years. I think my spare one was on sale $152 shipped five years ago.
I could have saved $100 by waiting. I have 54 microinverters and have had 3 failures one was just 20% off in producing but they replaced it. No cost to me they wanted that one back and paid shipping to get it back. The two others went to 0 watts output and they did not want those back. Unlike a string inverter I only lost production for one panel not the whole array or ˝ the array.

My ground mount will have shading issues as well, so unless I get permission to cut down the neighbor's trees... I'm in for $540 worth of Enphase M215's. I don't think I can touch a 4.5kw SunnyBoy and 20 SolarEdge Optimizers for $540. Back on the subject of rebooting my misbehaving M215, I'll have to do that tomorrow evening. I neglected to attempt to reset it until after it had already gone to sleep for the night. I head out the door to work before the sun wakes the system up. Looking at the input power graphs for this unit, the voltage readings are normal, the current readings are down at 0.210A or less. |

My spare microinverter is installed and ready to make power tommrow. They shipped my replacement microinverter today. I hope this is the last replacement but not very much down time is a very good thing.
They made is simpler to do a replacement in Enlighten Manager just go the setting tab and to the section. Then to the “Self Service” Select Install Replacement You then enter original serial number then the replacement serial number select submit that’s it, you are done. It is back to working 100% again.

Logged in through my Envoy, the bad inverter lists "DC Power Too Low" while the other inverters show "OK". As a result, I didn't seem to be able to determine whether I was able to successfully perform a reset on this inverter. In any event, the very courteous woman at Enphase was apparently able to look at the graphs and determine it was not performing as it should. She gave me a reference number, setup the RMA, then said there may be a 2-3 week delay before it ships. I told her I was in no rush, I had 22 new M215s in boxes to go on an addition to this 4.4kW array. I can use one of them while the RMA is in transit. |

Glad support took care of you. It is because I bought so many of them at a much higher cost they take care of me. (Not really I just got lucky)
Even know I will have my replacement next week I do not want to have one panel not making power that long that is also why I have a spare. Gasstingy did you call support I would love to see you get your issue taken care of.

After living with microinverters for several years I would say it's a good idea to have a couple spares on hand. Mine seem to be prone to high outside temps. I've never lost one in the winter. |

I think I'll save this for my 270W panels in the garage. |

12.5 kW array we generated 1,843 kWh June 2018
June 2018= 1,843 kWh June 2017= 1,823 kWh June 2016= 1,952 kWh June 2015= 1,994 kWh June 2014= 1,995 kWh Highest one day June 2018 = 78.1 kWhs Our system lifetime production is 97.6 MWh We have banked for the winter. 1,486 KWh Other solar producers show us your numbers for August when you have them.
