Is this necessary to do when setting up a battery system for the home? I will have the AC input, for charging the battery in case of cloud cover. But primarily using solar to charge the battery, to power a Hybrid AC unit in the evening and on cloudy days. Thank You

to unlock it does it work on talaria sting r mx4

I just checked mine its oct 2022 and the screw is there already but is that a good thing ? From what I understand is if the bond is there and you plug in (shore power) then there is 2 grounds and I think they cancel each other out (I think thats why they just started leaving that screw out but the board is the same)? Why don't you design a switch for the neutral ground bond that switches off when you are plugged in and on when you are on solar power? If you designed that neutral switch I think they would take notice as when I called them about this issue they suggested I follow the steps of your video ie: theres a video that shows that hack on you tube...

How long is the screw that you used

Ty for the video. But. The wire gauge: 10 vs 12 is a total mute. *bc; the 10-gauge handles 600v. The 12-gauge handle 470v. It will trip the main breaker well before any wire/circuit damage occurs. So Gauge wire isn't a "plus" when comparing these 2.

Did the instructions indicate that the closer to the inlet voltage the better? Being in the bottom corner The Surge still has to pass all the other Breakers before reaching the bottom of the panel

What is the installation method if the breaker box is recessed in the wall with drywall around it. Will the surge protector fit inside the breaker box?

FYI Thecspecvin the Siemens fs140 was only tested with the cable st 6 inches Siemens tech support told me when I asked. He explained that if any longer cable to the panel to shorten cable as much as possible. He slso said to twist the wires from the fs140 uniformly as muvh as possible before connecting to panel if I recall. I forgot exactly what he said butbif I recall, twisting the wires if using longer than 6 inches helped reduce the difference in the spec. I had the data somewhere after talking yltoma seasoned electrical engineer which showed me the Siemens spec was significantly worse in the specs if cable 36ninches versus 6 inches. Of course the Siemens manual doesn't discuss this but I sm positive via double checking with Siemens that the spec is for a 6vinch cable length only

I have this unit in an rv and when plugged into any gfci outlet, (which is most campsites) it trips the outlet after a few seconds. I installed the screw hoping it would fix that issue but it still trips. Anybody else with this unit have the same issue?

With NG screw in, will my 30A generator sense a ground fault or will it automatically unbound NG when connected and receiving a charge?

Having error code 19(no batt comm) I'm using just an ethernet cable from Walmart to connect to the batt. Do you think that's my issue? I didn't even look at the cables it came with lol! I will tho😅😅

I was told the fs140 was used on many military installs it does'nt list them because it's classified

I installed this unit in my home. I am not tied to the grid. I have power in from an outlet. I have check for the bond between ground and neutral but I get not signal meaning it’s not bonded. Do I need the bonding screw?

Thanks for that tip.

That was my question. Thank you.

Midnight solars SPD?

That's what you get when you buy a cheap Chinese made high frequency inverter.

Great video, ran into the exact same issues as you.

where did you terminate the ground on the ac output in the trailer?

Is the lug screw tight??? If the screw is not tight the screw does not have any connection to the terminal conductor..

I am glad you made this video. Signature Solar tech support told me how to un-bond N-G bonding and they pointed out wrong screw- the one near by heatsink- they even sent me pictures with red circles around the wrong screw head. After watching your video the N-G bonding screw was at different location. Signature Solar's tech support is just pathetic. The unit that I got from them was already un-bonded. I needed to NG bonded when the inverter is in off-grid mode. When the inverter was NG unbonded my furnace emitted flashing error code - 'polarity was reversed' and the gas furnace did not come on. So I followed your instruction to bond NG and it worked as I expected. In grid mode the neutral is connected to the ground of AC-in but in off grid mode the neutral of AC output is bonded to ground of AC out. Nick

Did any of you successfully get this stupid wifi dongle working correctly with the app? OMG what a huge pain. So turns out you need to use the SmartClient app to set the dongle up with the house wifi credentials while connected to the wifi dongle in your devices wifi access point list. I got that to work. Then you are supposed to use SmartESS to do the rest. This is where I got stuck. I was able to add the datalogger but that's it. When you click the little icon to the right of the datalogger and scroll down it shows disconnected.

thank you for pointing out the different cables and settings. Im sure you have saved many headaches from happening by releasing this video. I have mine on order so this is good info to know.

Thanks! This helped me to solve my problem this evening!

Is this the version 2 hardware.. Curved sides. That version should auto handle the bonding depending on input source in software without a screw. On your inverter, if you hardwired the screw and it's unbonded in case of ac source, it must be bypassing that connection internally. Thanks for the video and your comments.

Mine unlocked: 28 mph eco. 54 mph sport.

What if I were to use a Honda 2200i pure sine wave generator as ac input. The Honda is floating neutral. Would the Ev 3000 “disable” the neutral bond in this case? I think with floating neutral ac input (and no earth grounded bonded ac load panel downstream) you’d still want the Ev 3000 in internal bind config right?

Is it easy to remove from the swing arm? And transition back to the original mounting plate to put outside ?

Ever helpful. Just ordered this system so watching videos on it. Sure thankful for the heads up!😅

They must have given me that 7,8 pin cable then, I kept getting error 19 I think it was. Doesn’t have a sticker label like that on it.

If in AC Bypass mode, the inverter disconnects the bond from the output neutral to the chassis ground, how is the output neutral ground bond maintained on the AC output? Is it just then passing the utility AC ground and AC neutral through to the output (which is already bonded at the house's utility panel)?

Spencer, exactly how did you verify the neutral-ground bond of the inverter disconnected when it was running on utility power?

Are you developing a detected screen display screen for the EG4 3000 if so could you send me a comment

It's my understanding that this unit has generator auto start wiring configuration on the bottom side, from a will prowse video... Can anyone tell me how to find videos instructing me on how? I want to make a off grid camper thing with primarily solar, when it bottoms out, auto crank my generator. Please direct me guys....

Where did you buy the display and how did you do it? I want to use it for a camper van that I’m building. Thanks

Hello, just ran across your video. I've bought the eg4 3000w inverter. Eg4 ll 48v battery. Made a hand cart install like Will Prouse on CZcams. Finally got my dip switch configured and got my battery fully charged from grid power. I have a power strip wired up for my a/c output. I show 120v output on my display, but have @ 4 volts between line and neutral output, when wires are in place. Take the wires lose, probe the a/c output terminals, I have 120v. Tried wiring in a light; 120v on display, light won't work, and probe the line & neutral, and it show's 4 volts. Wondering if this could be my issue??

So does that mean the inverter has a floating neutral best suited to hook into a sub-panel that has a bonded neutral at the main panel of a house. I'm looking to build a mobile system to use at night during a power outage. All of my generators have floating neutrals, and cause no problems using a transfer switch on a sub panel. This is all new for me, thanks for any advice from anyone who might want to help.

Official info from EG4 on this topic m.czcams.com/video/nmf5Qc0VoYg/video.html

mine wont unlock , the wire has been cut and the sequence has been done. any tips?

I had the same problem just a few days ago when I set mine up. I was as nervous as a cat at a pitbull convention as I attempted to figure it out. I wish I had known of your video then!

Thanks for sharing, very helpful.

Hello Spencer. This is a great idea. I leave our box blade on the tractor for long periods during snow removal season, so this could really come in handy. Looking forward to your future tractor videos. Take care, Ben

Do you have any videos of the tv mount located between the door and window? Great video and ideas on the added mattress space!

Same needed when putting two units together together for split-hase config? Both or just one unit? Need to do some more research I guess. :)

Please tell us (me) how to build or get one of those remote control panels. Is there a reason you did not include a power on switch? thanks for all this info

Do you have a problem with it over heating? The manual says it needs 19” of clearance on the top and bottom and I’m trying to figure out where to put mine.

How did you do this?

The MPPT charge controller on the EG4 requires 120v of solar voltage before it will turn on the solar charge controller. If you use it for an RV, with limited roof space, virtually all of your solar will be used to power the controller leaving very little to charge batteries. So in my case 6 of my 7, 180 watt solar panels are just turning on the controller. The 7th panel charges the battery... ugh

Dude... you gotta do that differently in my opinion. I have a all in one and i do my bonding in the panel on my camper and have a switch for the bonding. If its bonded when you use ac input you created the ground loop which can freakin kill you or someone else. It will most likely pop the gfci on the ac input side having it the way you have it but if it dont trio it then it will hurt someone. Yeah man thats not correct with what you did in the video. They removed that bond in the eg4 for a reason. To save people from having to remove it theirself to be safe. I use a relay and it does it automatically but you gotta have some type or relay or switch on the place you bond.

Nice.
