For several years I've been researching why my Solaredge inverter was tripping, mostly from 10AM to 2 PM during sunny days and usually during cloud edge peaking. I started seeing "ARC Detected" on the inverter alarm log using Setapp. I have an SE7600HD and a 7.04 kw system with 20 panels. These...

That optimizer never allowed power production like the one removed. Tried cleaning connector, as well. I replaced with new one from SolarEdge and now it is back to the best performing panel, again. I quess all optimizers are not created equal! I'm going to try and return it.

Using the layout and analysis screens. It's supposed to be partly sunny tomorrow, so may be a good test.

I have P401 SolarEdge power optimizers on 8 - 370w bifacial panels. (P400's on 12 - 340w non-bifacial.) For almost a year the SE7600HD inverter would trip and restart on days when there was a lot of cloud edge power peaking. I narrowed it down to one of the P401 panel/optimizer using the...

Same here!

It is: US 240V No-Neutral. If you have a neutral there is a grid code listed for that, as well.

I have a Sol-Ark 12K with a SolarEdge SE7600H AC coupled to the Gen input breaker and have not had any issues. I have grid code 14 on the SolarEdge and with the grid protection set at 60.5 Hz the unit will receive a 60.5 Hz signal from the Sol-Ark in one second and shut down.

Either at the contacts or in the load panel. I put it in it's own metal box close to the pressure switch. It does get warm so I wanted it isolated. I have a 3/4 HP 240V pump and they sent me an SL22 4R014.

I was was looking at a soft start for my 2.5 ton A/C last year. I found a company called Ametherm that makes NTC thermistors that are designed to lower inrush current. NTC = negative temperature coefficient. Sent the nameplate data to them and they sent me 2 to try for free. Only need one and it...

Can you explain how the Sol-Ark responds when Power is set to 9000, 50% on battery and charge selected? Using Limited to load. Thanks!

If a time period had Power at 8000, Battery at 50% and charge selected would the system get confused at the 50% point?

No load idle is supposed to be around 60 watts on this model.

Thanks for this! I was only using about 350 watts. First time I've seen this drawing!

Today I just started using My Sol-Ark 12K in Time of Use mode. At 5 PM I have it set to 9000 watts, Battery at 25%, no sell or charge checked. Limited to Load, Time of Use and Grid Sell in upper left corner of screen checked. When my furnace started I noticed that the Emporia Vue I have...

Thanks for the time you took to type all this! It helps! With my usage and battery size during the winter I could probably go 24 hours on the batteries alone with not much sun. In the summer with no sun, it would, also, be close. I could tweak a few areas and monitor the results. I like the idea...

Thanks for the recommendations! Couple of things: I don't understand checking the "Sell" checkboxes as I don't want the batteries to discharge to the grid. (AC coupled to Gen Input.) Am I missing something there? What does Power at 0 do? Is it to ensure nothing pulled from the battery at that time?

The 13:00 setting on yours has 50% and no charge checked. Does that mean at less than 50% the load will transfer to the grid?

What will the TOU do differently if all the 100% time periods "Charge" were not checked or, even at a lesser percent?

I have a Sol-Ark 12k with AC coupling to the Gen breaker of 7 kW and no solar on the DC side. I have 15.3 kWh of batteries. Loads out to a critical loads panel. My utility is going to Time of Day on April 1st. (No joke) They are going to have 3 rate periods. 5 AM to 4 PM 11.45 cents/kWh. 4 PM to...

Are you AC coupled through the Gen Breaker or DC coupled with this setup?

This is information about what I did to prevent my Solaredge SE7600HD from tripping due to high AC voltages. In April of 2022 I discovered my inverter was tripping off during the day mostly due to when the clouds align and make power spikes. My system is about 120 feet from the main panel and...

I wish the Sol-Ark 12K I have would be able to "Throttle" my Solaredge inverter using frequency like your MPP does! Maybe they'll get there someday! Seems like it would be just a software update.

Under the "Reactive Power" screen you show a "Priority" and "Reactive Priority" to the right with a > after it. Click on "Reactive Priority" and see if it gives choices. Reactive Power Priority is enabled by default when setting the appropriate USA Rule 21 country code. "Active Priority" is what...

From my experience it seems that Reactive Priority is more of a California grid thing. It could reduce inverter power if voltage gets too high. The country code I'm using (USA 240V no neutral) doesn't give an option to go to Reactive Priority.

Why did you use "Reactive Priority" over "Power Priority"? I see that your current limit goes to the 7071.87 amps just like mine on about anything that is done with Setapp. I always return that to what my system is designed for. Don't know if it matters.

My 15K only shows the one screen. On page 5 of https://www.sol-ark.com/wp-content/uploads/2022/08/Battery-Communications-Integration-Guide-V2.8-1.pdf, it shows that for CanBus it will only show limited data. Page 6 is for RS485 connections and they get detailed battery data. Also, for others...

MCU: 6212 updated this week. Comm: 1432-0717. BTW, the only solar I have going to it is AC coupled.

For the 12K outdoor model I've seen 80 watts draw for the short amount of time I've had it installed. Would love to see 50 watts!

Battery firmware? Emailed Sol-Ark today and this is their reply: "Right now we don't have any on-going test with the EG4 LL, we don't have any request from Signature Solar to test and get the close loop comms with the battery. All tested batteries will appear in the battery integration guide...

Just installed a 12k in the last couple of months. Did the initial software update and occasionally look to see if any new one is available. I think Sol-Ark recommends updates if I remember correctly. Looks like I'm 2 versions behind after checking today. I have EG4LL batteries and understand an...

Just wondering if anyone has used the "Alternative Power Source" mode on their SolarEdge HD inverter when off-grid and AC coupled to a Sol-Ark 12k? If so, what did you set the P(f) and P(V) values to on the SolarEdge and would you explain how it worked for you? If you don't use the "Alternative...

I have the manual and have watched many You Tube videos, but haven't seen any how to's, yet!

I know I should be able to, but where?

I am setting up a Sol-Ark 12 K to be used only for grid outages. I have a Solaredge Inverter that I will AC couple to it. I was wondering what people do to ensure their batteries are charged for the evening? Is there a setting to make sure they are fully charged late in the afternoon off the AC...

Thanks, I'll have to look into that!
