Hi there. I am considering purchasing this Envertech 360 micro inverter. I have a question regarding this. It accepts input up to 450W from 12V panels but only offers 360W output. Why such a loss? 90W is a lot... Even if I plug in 450W, I get 360 if I understand correctly. Is this normal? The rest go into heat?

no, in 48 V to be confirmed. https://www.ase-energy.com/Files/133004 ... asheet.pdfdarwenn wrote: It accepts input up to 450W from 12V panels
These are 2 different routes:
Input MPPT controller
Output mains inverter.
and that's direct without battery storage these inverters.

It's not abnormal. The peak power (Wc or Wp) of the panels is a value measured under standardized and ideal laboratory conditions. In "real life", with panels more or less well oriented, more or less dirty, and in our latitudes, they will never produce this value (or so a few hours a year), but let's say, at random, at most, 80% of it. Hold 80% of 450Wp, that's 360 W real....
All this is well explained on this page from SMA Solar, a well-known inverter manufacturer. There seem to be up to 200% "oversizing" (peak power value/inverter power value) in countries like Belgium.

Re: Question about Envertech micro inverter
Thanks for your precisions. The voltage range goes from 16 to 60v which logically works for 12v panels which deliver about 22v. The fact of not storing on battery is precisely what I am looking for.

1. what I wrote is what I think I understand, but of course you have to have it confirmed by the supplier.
2. On the voltage, it's beyond my competence, but I read "22V starting voltage".

In 12 V the performances will not be optimal.darwenn wrote:Thanks for your precisions. The voltage range goes from 16 to 60v which logically works for 12v panels which deliver about 22v. The fact of not storing on battery is precisely what I am looking for.
The kits are equipped with 24 V PV.
You can couple them in parallel series, without forgetting the bypass diodes.
