Hi David, I am very interested in this. When doing off grid (no permit), can we install panel on the roof of the house?

Thanks for the insight. I had the same problem with my 6000ex-48hv which I bought from S.S. Since day one, it was giving out some circuit board burning smell when under heavy load, and eventually stopped working. Fortunately I was able to sent it back and had it repaired and shipped back to me by S.S. under warranty. In the repair note, they indicated that the rectifier board and battery terminal board were replaced. The repaired unit has been working for almost 3 months now. No burning smell whatsoever.

thanks for taking the cover off and showing the problem... I bought a refurbished unit, wired it up, and it fails after about 20 minutes running light loads for testing. L2 output blinks off, re-sets, comes back on and runs for a couple minutes, and blinks off again. likely same problem that you show with bad connection to main board, but I can't repair that myself, and SignatureSolar does not return calls.

eg4 customer service is horrible I have this same inverter thanks for the video

What about the configuration ? This part is missing on the video

Good job. I have tightened up the bolts on my unit and will keep it. This is the Rosetta Stone for understanding the weak spot of a great unit.

your not to turn on pv until the batteries are installed... it can screw the capacitors

Eureka, you have found the weak part of this piece of equipment. I have run across this problem with other equipment. When you’re working with higher current levels, the wires on the circuit board at interfaces between wires and the copper on the board can cause heat and melt the solder connections. As someone else has mentioned, tightening the main Connectors will help but sometimes, you have to solder the connectors on the circuit boards. Sometimes even on both sides. I have this exact inverter, a low frequency inverter. I was shipped an EG5 6000XP, and I decided to send it back in Lou of keeping the 6000EX. There is a certain level of inherent noise on high frequency inverters. The low frequency, inverters have cleaner LINE outputs for Ham Radio use. The HF bands do not have as much noise. My electrical engineering, friends and solar installers, and Solar engineers have told me that historically the low frequency inverters last longer and are safer on critical electronic equipment. High frequency, inverters have a normal life expectancy of about 2 to 5 years. The low frequency units usually last longer unless if there is a Design Flaw. This looks like a design flaw. Thank you for identifying the main problem that has been seen with this unit. I will keep my eyes open and pop the top and check the circuit boards and resolder them if needed. Tom N8BKJ

I bet you that high frequency, transformerless inverter won't even last you a year. Should have bought a low frequency transformer based inverter instead.

Same issue. BP error. Shut downs on battery. Arcing and sparks. Opened it. Every battery DC nut was loose. Tightened and running perfectly. The issue it to catch it before it burns and you should have a good unit afterwards. The refurbished one I was sent by signature also had the same slack nuts. Tightened and that one worked as well. The tightness also clamps at the back and would be very shaky/wobbly without sufficient torque and cause the burn/arc

Very nice bro! I am also from Belize! I honestly don't know how I stumbled on your channel but I am happy I did. I also went solar grid tied, but one of my mistakes is not buying from signature solar. I have sungoldpower hybrid inverter charger but its glitchy right now. Manufacturer sent a replacement part, hoping that solves my problem! Cheers!

I bought a refurb 6000ex right before the 6000xp came out 😡. Have run my house on it for about 5 months and no issues so far. I’m definitely going to check the terminals and try to avoid the same issues. Will ultimately be replacing it with two 6000xp which appear to be vastly better built units. Thank you for showing the damage on your inverter and I hope the xp is a trouble free replacement for you! 👍⚡️☀️💡🔋

Hi, do you know where i can buy parts for this unit? S,S wont sell me any parts

they have discontinued it 1.5 yr ago

Schneider … pay the extra $ and rest easy

If you want to learn why you should never buy a Chinese made, high frequency inverter for offgrid use, search youtube for the term "low frequency inverter vs high frequency inverters"

With all of the well documented problems that the EG4 6500EX inverters are having, why on Earth are you promoting the purchase of these cheap, high frequency output transformerless inverters? There is very little difference between the EG4 6500EX and the EG4 6000XP. They both use low cost, high frequency inverter tech which yield a shorter life expectancy and a far poorer peak power capacities than "Real" heavy duty, low frequency, transformer based inverters. There were no major design changes between the EG4 6500EX and the EG4 6000XP. A change in color scheme and a few minor differences in the component layout is about it. The Chinese have been trying to get their high frequency inverter tech right for over 30 years and have not succeeded and probably never will. Don't take my word for it, Google or search youtube for "low frequency inverter vs high frequency inverters"

I had the same problem on my lvx 6048 mine was refurbished i notice the nut was loose and the solder over heated i change the nut and resolder it that fix it more than two years now

I repair inverters for a living have done so for the past 24 years. The burnt DC terminals in these inverters are indicative of either loose terminals causing an arc or a short circuit on your FET board probably from a shorted capacitor or shorted MOSFETs. Do you have fusing or a DC circuit breaker between your battery and your inverter?

That's what you get for buying an inverter from Sig Solar. I would never buy any of their inverter products. Especially their high frequency, transformerless inverters.

I just watched this video and see you are not in the States which would make exchanges hard. I would like to live there a while, but I know it will never happen.

They were offering a trade in for the new one. There was a cost but you would get something for the one you replaced.

Good video. 👍

Nice work. Are you using both outputs. 120 and 240 v ? What is your main voltage?

what size battery cable you use?

Why do these EG4 inverters have so many reported issues?

Waste of time

Very nice!

I am going to take it for granted that you plan on adding more storage to the system later. Hope the inverter works well for you.

I recommended a friend use signature solar because they had a good reputation. Turned out to be the worst recommendation I could have given. They proved to me they have the worst customer support ever. Their "chargeverter" almost burned a buddies house down, and then they totally ignored the emails. It turned out to be a faulty solder point for the smoothing capacitors.

Great Job!!!

Nice job! Maybe put the batteries up on the wall, just in case. That little slice of paradise is really close to the water!!

Good luck if you ever need Customer Service.

I thought the max voltage was 480

Hope your head is healing up and your no longer have any pain! Blessings and Health in the New Year!

thank you so much your the first personthat show installing eg4 inverors.

You may want to put on marine grade heat shrink on your DC cables to prevent corrosion over time.

Nice solar module installation but next time, I would highly recommend using a low frequency, transformer based inverter instead of that lightweight, low surge, high frequency, transformerless inverter. High frequency inverters have a shorter life expectancy than low frequency inverter and they also offer a poorer surge capacity.The reason for this is that all these high frequency inverters lack a very critical component. That critical component is an iron core, copper wound output transformer. Without an output transformer to act as a buffer to absorb electrical surges provided by the “Flywheel Effect” inherent in the physical amount of a transformer’s iron, these surges and damaging reverse voltage spikes must be handled directly by the inverter’s MOSFET transistors, essential shortening their life. You might be able to start and run some high surge loads when these solar generators are new, but every time you fire up that inductive load, you're shortening the life of the MOSFETs in your solar generator's inverter. You may be able to start and run some of these loads when your high frequency solar generator is new, but every time you power up and power down an inductive load, you're shortening the life of the MOSFETs and capacitors in a high frequency inverter. They also run much hotter than low frequency, transformer-based inverters which makes the low cost, off spec, Chinese made components such as capacitors, diodes, MOSFETs, resistors and ICs that are used in these cheap inverters, far more prone to early failure. Another major consideration with these high frequency, transformer free solar generators is safety. All it takes is for the AC output circuitry to fail and one of their MOSFETs or IGBTs to short to ground in the H-Bridge and a high frequency inverter can send dangerous, high voltage, high amperage DC current straight to your connected AC loads which will not only damage most AC appliances but can also set those AC appliances on fire. Another major consideration that is never mentioned by the majority of the paid CZcams product hucksters, is that the vast majority of these solar generators are non-repairable. After the warranty runs out, you're not going to be able to ship a high frequency inverter back to the manufacturer in China and have them repair the unit. At a typical shop rate of $125 per hour in the US, with no schematic and limited parts availability, it makes no economic sense to even attempt to repair one of these units. Once the FETs have fried and have taken a good portion of the inverter's PCB with it, (And trust me, sooner rather than later, they will fry.) they basically become a brick. A far better alternative is to invest a little more money and purchase a low frequency, transformer based inverter charger. Low frequency transformer based inverters last far, far longer and can easily power high surge loads without being damaged. That's why the big name brand inverter manufacturers like Schneider Electric, Outback Power, Sigineer Power, Magnum Energy, Victron and others, all use a low frequency topology in their offerings. I know this to be true because I've spent the last 23 years repairing inverters. High frequency solar generators/inverters simply don't last when powering inductive loads.

What batteries do you have?
