Update to this. I have not tried to contact SE on this and as of now, probably won't. I do not know how it does it (way beyond my paygrade) but my system has recognized the new optimizer that I installed, including the serial number. At $40 for it, I'm not too incentivized to harass SE over it...

Thanks, I'll give that a shot next week. Their website does say that, now that I look at it. I knew that $1550 for the repair was out of line and on top of it, they guy told me that my warranty was only 5 years. I don't know what that guy was thinking but when all is said and done, I'll write...

Thanks for that information. It's all above my paygrade but now I have a direction to look and some things to learn.

I bought a portable power supply so I'll have some power at my primitive camp and I want to connect some solar panels to it for charging. It is a 2000W power supply and the specs call for not more than 48V input through the solar connector. I am not finding anything regarding maximum wattage...

Thanks for everything, I watched one video on it and am starting to understand it. A question that I have on my existing system...it looks to me like the panels have a combined VOC of 684V but my inverters are only rated for 500 DCV input. I do have a friend who is more knowledgeable than I am...

Hi folks, thanks for having me. If I'm in the wrong spot with this, please help me find the right spot. I'm pretty much in the dark on my system but it looks like time for me to figure it out. I have 72 Peimar panels on my garage roof. Each one has a SolarEdge optimizer on it and it appears as...

I was just digging in the depths of my monitoring system and it looks like voltage tops out short of 400 VDC. I have four pairs of wires coming off of the roof into the inverters, which leads me to believe that it's just four quads. And when I open up the inverter stats, it shows two strings on...

Wow, I wished I was as smart as you.

OOOO you and your math. :ROFLMAO::ROFLMAO::ROFLMAO: I'm so glad you stepped in here with all your knowledge to help me out.

Have you gotten a shot of the specs tag on these?

Forgive me for my ignorance but I am a retired working man and have little knowledge of these things. I have a grid tied array on my roof and I want to know if it would be feasible to add at least some battery storage capabilities to it. I have 72 panels on two Solar Edge inverters. The array...

Well...how's 400/560=80% sound?

Thanks for the information. That takes the wind out of my sails. I was also hoping to use it for long term in the event of a loss of the grid for long periods of time. So if that were to happen, I'd need to go up there and remove the optimizers.

Like I say, I am clueless and all I can do is tell you what the specs are on my system.

Thanks for the heads up but it's not quite what I seek.

I have a SolarEdge 19.4K system and recently added an EG4 18K PV inverter and backup battery. Battery is homemade 48V LiFePO 43K setup. I had a guy install the system and he did a great job and everything worked as it should until I changed a setting and selected forced discharge to see how long...

Can the sinewave to activate the inverters. Can the sinewave to activate the inverters come from something like a generator or another battery with an inverter on it? Would it be possible to bring the system up that way and disconnect it when the batteries get close to full charge without...

I am looking into adding a Tesla Powerwall 2 to my system and have a meeting scheduled with one of their guys this week. I'm curious to hear what he has to say.
