very good--thanks!

OK! after two days of trying to get my PowMr inverter to work with no avail I finally found your video. I hope I can ask you a couple of questions. I can't get my transfer switch to work. The red and black to the main panel are good. I'm using a single phase 120 on all breakers. My 24v 3000 w inverter has three terminal ac IN but only two terminals on ac OUT, no ground third wire. I wired the ac in to an extension cord for battery charging. I connected the ac out two wires to the transfer switch red and black wires. it does not work. I don't know how to ground all these wires and maybe that's the problem. I don't get it itwatching the video, i'm not too savy.

Great video as always, if you don't want to use an ATS, Can you make a video on how to connect AC input from grid to Inverter, i get confused a lot on how to do that.

Thanks for the video. So, having a transformer to generate L2 is not needed? Or maybe only needed for a critical loads panel when not using a transfer switch.

Congrats, great explanation! No any question :) You pass :). I will share video to friends from US. In EU\Poland we say a "grid - generator switch" for a "grid - off - generator switch" a transfer switch like you say :). BR and take care !.

¿Para un sistema off grid puedo tirar un cable ground desde el panel de breaker principal al panel de breaker off grid? ¿O deberia instalar un nuevo ground independiente especificamente para el sistema off grid?

I am left with a question: Is it a correct assumption to NOT bond a cheap inverter at the breaker box? Meaining one of those 60VAC HOT and 60VAC NEUTRAL type of inverters that are not bonded. I get that you shouldn't bond the neutral and hot of the inverter but you didn't mention about doing so at the circuit panel. At this point I wouldn't proceed before verifying this assumption but am assuming that is what you meant here... Sorry if this sounds confusing.

Dear Clear Media, We all need to be aware of the common neutral that seems to be inherent in these Manual transfer switches. This means that it only works with inverters that support common ground. Can you please make this more clear ?

how dangerous is to have unbonded ground?

Looks like your assessment on PWM is incorrect -- PWM does in fact aim to keep the same overall wattage by raising the current when it decreases voltage to match batteries. Albeit more efficient losses.

May i ask something please I just want to make sure. As i understand 1.If my inverter does not have neutal-ground bounding inside, i just bond it outside right ? and it will work for all cases. 2. If my hybrid inverter has neutral-groud bonding on the input side, i should not make neutral on the output side and ground touching together (bonding) right ?

The best information on Bonding off-grid systems I could find on the internet. Thank you.

One of the best instructional videos I've seen, hands down. Thank you.

Big thanx. I have watched this video 10+ times, directly front of the powerbox and inverter and have done everything according your explanation. Now my Jacuzzi has started working and if my wife is happy...I'm to :D The difference is only that I have a EU 220V system and all the values where 2x.

Good information, well presented. Thanks!

Thanks a lot great video… did you use the same breakers from the 220 ? Just removed the metal bar ?

Great teacher!

I saw 1 guy get inside and switch the red and black wires around on a 2000w wzrelb/Reliable. Is that a safe practice?

I have one of those giandel 24v 3000watt inverter. What size cable would I use to wire the terminal block to a breaker panel?

My average is less than 10 per day. Remote work, so lvl 1 charging works fine for me.

Do you have a patreon so we can support! Finally a CLEAR explanation with great visuals! What about grounding solar panels or batteries? My Sun Gold 5kwh wall mount battery has a ground symbol. Is that only if it's outside?

Excellent

Excellent...

I’ve got an EG4 3k inverter and battery that I tried to use for someone with no grid power due to a storm. Operating it in battery mode, I saw the same voltages as an unbounded neutral ground inside the inverter. When I ran it with a receptacle tester, it said I had an open neutral and was blinking. I tried plugging a newer Whirlpool refrigerator into it and it did not run. I plugged a lamp and/or a fan in the receptacle and they ran and the refrigerator then ran as long as either the light or the fan was running. Can I create a neutral ground bond in the receptacle. Is that a safer way to operate? FYI, I think the bonding screw was not put in the inverter in this version. If I were to plug in an AC in into the house receptacle, even though the circuit is dead, would it create a neutral ground bond?

while using SBU mode. always charge battery from the grid or solar. and again it use battery for night. like that grid charge and use battery. does this damage the battery. or reduce the performance off the battery.

I think this helped me to see if my inver is bonded it’s not but I can do it in a panel

Thanks very informative I learned a lot 👏👏👏

ok i got it will balance the soc during charging time and the question is did it balance also the soc during discharging time?

Given the number of small components and dependence on extreme cooling in an HF inverter can I trust it like an LF to last for years of abuse? HF has evolved over the last few years but so have LF inverters. I'm still skeptical when we are 100% off-grid.

Aptera info is a pack of lies and it just vaporware.

Click bait!

Adapters are everywhere... new laptop without ethernet port and adapter. Maybe next episod about grounding a pv modules and surge protection as final part4 :).

For me in additional information at webpage we have a excel file "VE-MPPT-Calc-4_0" and we can specify own a pv modules and compare how many of them are ok for a charger and on what configuration parraler/serial - this is awesome and a litle of ppl use it :( I unlock a protection and add own entry about popular charger like easun 6048, soyosource 1200lim48 etc. to select a modules who are best for many setups.

Unfortunately, my IQ seems not to allow the numerous videos I have watched about basic electricity stuff to make sense. Your video seems great for the person knowledgeable in the jargon, but I am lost. I assume that the batteries have a continuum between 0% full and 100% full? Is there a way that I can check the current "fill level?" I don't know if that is called volts or amps or watts or something else. I definitely have not been able to find it on the panel.

This should be your first movie. Nice app.

End is litle complex, if you show a graph of both box-es and show a marked line in grid/off/gen position then this will build a easy to understand path of cable connections. But, of course perfect video !.

Very impresive way who you do a video mounting :). Nice.

Biggest question is about self consumption from battery, ~50-70W ?

You can only connect Bluetooth one piece of equipment at a time ie phone or tablet etc

Hey mate, my victron app doesn't show any wattage only under load. So you think it's in mt settings? Thank you

I don't have a ground coming from my inverter. Actually a Growatt with a transformer splitting the single hot 240v into split phase L1,L2 and neutral. Edit: So I called Signature Solar and inquired about my Growatt 5000 ES, they told me it is not internally bonded. I also downloaded the manual for the Pro/Tran2 306C and on page 11 it states "The Protran2 does not switch the neutral wire. As such, it is intended to be used with a generator that has a floating neutral (ground and neutral not bonded) configuration" Which is what the Growatt is, essentially it operates as a gas generator as far a a floating neutral. The Pro/Tran2 should be able to run off the Growatt with L1, L2 and a neutral, but, I need to figure out how to ground it in case of a short circuit without creating another bond in my system. If I was to provide a ground, that I do not have coming from my inverter, but provide it from my panel box, would that create a double bond?

Sounds like you got a new mic 😊

Unless i missed it you did not cover what to do when using 2 mpp solar inverters in split phase with grid input. Do i remove the bond screw in the 2nd inverter or will it work as it comes from factory letting the ats manage the bond in both inverters. Thanks

Hi. Thanks for the videos. So I currently have 2x mpp solar lv6548 inverters wired to a sub panel in split phase operation. Based on your video, i would have a bond loop as these inverters come with an internal bonding screw.. each having their own screw. As I understand it each inverter provides seperate 120v circuit to each bus bar seperatly in the panel. I will perform these tests to verify. These units also have internal ATS wich as I understand connect and disconnect the bond as needed when switching to grid ac in for bypass or charge. I soon will be connecting the ac in from my main panel to the inverters. Do I need to remove the bonding screw in the 2nd inverter when in off grid mode no ac input on either inverter. There seems to be a catch 22 here. When switching from grid to no grid ac input you cannot very well open the inverter each time to reinstall the screw just cause u need some juice to charge battery. Can you clarify what to do in each senerio keeping in mind that the inverters also switch between off grid and "grid" mode when needed. Do we have a design flaw here.. ty

This worked perfect for me. Thank you soo much for doing this video.

Question, i have my mpp solar inverter running as a ups, i have it plugged in a gfci outlet and when i have hooked up to a direct load or sub panel everything works fine, but when i hook it up to the transfer swith to the main panel it trips my gfci outlet for the input. how do i keep it from tripping? i removed the ground neutral bond in the inverter.

Very well explained!!!!!! Thank You

Hi, I really enjoyed your videos. What type of junction box did you use to extend the wiring from the flush-mounted sub-panel to the transfer switch? I need to do the same thing for my transfer switch. Thanks.

any chance of an in depth vid as to why these cheapo inverters are wired like this? seems dodgy as hell.
