Everything You Need To Know - Enphase Micro Inverter Review

[@ram64man]

Team you need to stock iq8 models , for soft offline mode, and also battery backup mode for full off line support

I have old, (2013) Enphase Microinverters here in australia on 8 old but expensive 300w panels. I have a Solis string inverter (2019) on very cheap 300w panels. I have a brand new Sungrow string inverter (2024) on good quality 440w panels. Out of the three systems, suprisingly, the ancient Enphase inveters are the most efficient for their wattage. It's not a gimmick, they actually are by far the best. Out of the two string systems, the cheap one is every bit as efficient as the medium quality. SO my advise is this, buy Enphase if you can afford, but if you can't afford, don't hesitate to get even the cheapest alternatives because they still work well imo. Enphase micro's are the most impressive though, and the installation is by far the neatest and simplest.

If you have AC essentially coming off the roof with the IQ7+ does then that have to go through a conversion back to DC if you have a home battery to fill up from the Solar Array as well as using an off peak tariff to fill them ?.

[@Heatable]

Hey Andy, yes that’s right it converts to AC and back to DC when going back to the grid and battery storage.

[@andyballard1883]

thanks for the reply, does that mean you need a second inverter down at battery configuration to take it back to DC or is the battery interface and management software designed to handle that@@Heatable

[@Heatable]

@@andyballard1883 Hey Andy, yes that's right - the battery either has a built in inverter or the Givenergy battery, for example, has a separate gateway that converts it back to DC. More than happy to help with any other questions!

[@boldford]

Why oh why didn't Enphase make the IQ8 micro-inverters compatible with the IQ7 series?

[@ipedros7]

Immediate question then is if you want to put part/all of that generation into a battery you will have 15% conversion losses? From there, any generation then is pretty much designed to go straight to load and excess to grid. Considering the cost of each microinverter, which in effect makes PV panel + inverter becoming 250% of PV alone cost. In all, I cant see how microinverters stack up overall.

[@Heatable]

Hey! The total loss to convert would be around 6%. This conversion factor is similar to charging the battery from the grid.

[@TonyFromarty]

Are Enphase microinverters stand alone or do they need a controller to function or be set up and commissioned?

[@Heatable]

Hey Tony, the micro-inverters are connected with a metered Envoy that allows you to read your import and export data.

[@TurreTuntematon]

Enphase rocks 😊

I know it is not ideal but Can you use a 195watt solar panel with IQ7

[@Heatable]

You could but it would be limiting to performance. Generally, you'd oversize the panel by 30-40% to the gross output of the inverter.

[@DaverHacisabanoglu]

Thank you for your repsonse, can I combine two 195 watt panels in series and use one micro inverter for every two panel. @@Heatable

[@Heatable]

Due to the voltage of individual panels you wouldn't be able to feed two into one inverter. @@DaverHacisabanoglu

Hi friend you very skill are you like me very nice
