Long story short. My EG4 18k had a short and batteries no longer would charge/discharge so it had to be returned. A day or so after I found this out the entire unit made a loud sound and completely stopped working. No lights or anything. Solar Sovereign said they were waiting for approval for...

I had same issue with battery short. I purchased from Solar Sovereign and now waiting for RMA approval from Signature Solar. Only mine basically blew up and won’t come on at all anymore. I heard a loud boom in my garage and power went out. Went out and no lights on screen or anything. None of...

Not sure if any of the settings are relevant to this but here are my current settings from the app

My initial post has alarm record when it stopped working

I can’t get alarm off or run on. I tried forced discharge to use the battery and ac charge to try and charge from grid since it won’t charge from extra solar it sells back to grid. Which is what I want but after batteries are full. They ran fine for first couple months then this. Only change...

It’s weird because the battery icon is green on app but orange on inverter. Also it’s showing 68% on inverter but both batteries are showing 75%+. The battery icon on inverter turns red when comm cable unplugged.

Battery 2

Battery one(master)

Are you saying to just disconnect communication wire from master battery to inverter? Or disconnect battery to battery? Also not surprised at all (sadly) I was told I’d be called back in half hour at 4:30 yesterday and wasn’t. Seeing as they did same thing when they couldn’t figure out my ac...

They are in my garage so between 65-75. Alarm is on and no power being supplied. Not sure about voltages but here is the battery section on inverter. Not sure if this helps at all. I hope they can fix issues because I wouldn’t even know how I’d send them back seeing the size and weight.

So I have 2 power pros that have been working for a couple months with my 18k pv. Last night they ran from 100% soc to 68% and stopped. I got temperature over range and they been working since. The inverter has the battery icon as yellow but it’s green in the app. Not sure why. Was on the phone...

I use Polaris connectors in a 12x12x36 or 48 box I think. Both switches bought at Home Depot.

I did a similar setup but wanted the option to isolate the inverter so I put a disconnect inline.

I have two powerpro batteries and wanted to add a third. My question was can the battery cable from the parallel batteries be different lengths? I read that the lengths should be the same on paralleled batteries. And is there a max distance with the wire size that is provided with the powerpro...

I turned on the batteries and I connected the 5 panels on the ground, restarted inverter and I’m showing wattage. Thank you again for the suggestions. It’s really cloudy today so not much production. I’d like to know what settings I need to keep my batteries as just backup for now but still...

I have a older SolarEdge system ac coupled. I shut off my power pros because they kept draining down when I didn’t have enough power coming in instead of drawing from the grid. I wanted the batteries as just backup for now until I get more solar hooked up that can cover my daily usage. I DMd...

I hooked my 8 400w Canadian solar panels in series and could only get volts no wattage in the #2 mppt on 18k. I then tried to just hook up 5 panels in series on the ground just to make sure it wasn’t something with the wiring on roof. Im still only getting volts. I double and tripled checked...

I had grid sell back set to off. I changed that to on. also, turned off " run without grid".

I changed some suggested settings and it appears to be working now. Thank you to everyone who replied

Anytime I try to change any setting in the app I get unknow error message or operation failed

I took screenshot of my settings and my inverter screen to help see what my actual settings are at

On the inverter the off grid out output is checked but I’m currently using all my power from the grid because I have no solar tied in yet. I wanted to get the current system i had up and running using the SE inverter ac coupled before I tie in the rest of my solar I installed myself that has...

I checked it with multimeter and had 0

SE6000

I have a SolarEdge inverter that worked good before I installed my 18k. I hooked it up to the 18k gen port and now I have no power to SE inverter. The ac couple setting is checked on 18k. But SE support said their is no ac power. I’ve been on the phone with eg4 CS for 4 hours total from today...

Would 8 gauge thhn be sufficient or no. I used 8 gauge solid copper for racking ground.

My current project is adding on to an existing system I had installed by a company. I checked and they have a green wire ran in conduit with pv wires. So what size wire do I need? It is 4.4kw additional panels in series at 25amps

I tried researching the answer but get confused between ac and dc systems. I want to make sure I do this right so I’m going to just ask for my specific installation. I’m running dc from panels with tigo rsd to Eg4 18kpv using the mc4 wire since it’s a short run, straight down from roof to...

where did you see the free shipping?

I see on specs of the 18k that operating mppt is 120-500vdc

Thank you for the reply. Its the tigo RSD. I was actually planning on two 11 panel arrays. But figured I’d concentrate on doing only one at a time. Plus they are at opposite ends of the house with the inverter basically in the middle. I came to the number of 11 because it was below the 600v...

So I’m wanting to run 11-430w sun power panels with tigo in series to a eg4 18k mppt port. Its going from panels on the roof—>junction box on roof—>attic—> inside garage(inverter location).im trying to find out 2 things: if what im wanting to do is correct setup. And if so, can I run a straight...
