My bet its one or several MOSFET, thats the typical part that breaks on these inverters, 99.999999% of the time. Plus i have a good BMS in the chain set to 150Amps that would have avoided frying the whole bank of transistors.

To all looking into this thread, the inverter ran well for a couple of weeks and then blew up. If you encounter the same random W028 overload message with nearly no load on the inverter your unit will most likely die soon. See this thread for details...

My inverter was throwing Overload messages, randomly shutting down with as little as 200Watts connected to it right out of the box. Strangely the problem went away as soon as i lifted the Battery voltage from around 50 to 58 Volts by adding two more cell blocks. Of course EG4 never replied to my...

@saggys i had plenty of second thoughts rolling the dice on a chinese inverter, especially after watching this video: I still went for the EG4 thinking that the lack of a transformer and reliance on sensitive MOSFET transistors is neglect-able due to the low cost and (so i assumed) readily...

Just a quick update , my system is down for over a week now. I still have no official response from EG4. @SolarGuys started a a quality claim at their end but do not keep me informed, i sent several emails to get a status with no response, called in yesterday a guy named Adam promised to...

Just sent DM to you. Thanks for the support!

SolarGuysPro contacted EG4, i have still no News. Nobody even asked for the serial Number of the Inverter to look into its Data Log. Not sure if EG4 products should be marketed as "Off Grid". If i was really of grid right now i would have a real problem with that lack of customer support and...

I am a automotive master technician working on Tesla vehicles, i guarantee you the unit is connected correctly, there is nothing to see in a picture with 7 connected wires. I am waiting for official response from Eg4, solarguyspro.com opened a quality ticket with them. Lets see how long that...

That does not describe what table should be applied, 14.1 table is labeled Error/Warning codes, the codes start with an "E" . Why wouldn't they use a "F" and call it "Fault table" instead, to be consistent with the page you quoted and the "W"used for warning codes in table 14.2? This manual is...

yes, correct, online log brought clarity, w026 battery voltage low a 6:33am. The detailed log shows that the inverter started to charge the battery at about 7am. It went from 0% charge to 6% until about 9am when i stepped in and rebooted the unit thinking its the 029 internal fault. I checked...

Like many other battery banks mine do not have pre-charge resistors, nor is it required to do this by the inverters specs. Anyway i have stopped and started this inverter many times before, nothing ever happened.

Yes, thats the normal startup procedure i followed. Everything off, then turning battery on first. How does that pre-charge capacitors?

it only showed code "26" on the front panel, to this day i dont know if that should be taken as W026 or E026. Pre-charge the capacitors? Can you point to the page describing that process in the EG4 manual?

My new EG 4000 was running happily for a couple of weeks until this night the battery ran low and the inverter switched off power supply and threw a 26 Error code on the front panel. Checked the manual, it stated code number 26 to be a "internal fault" and to restart the inverter. So i turned...

the Lux manual is a bit better but not much, https://luxpowertek.com/wp-content/uploads/2023/08/SNA-US-6000-User-Manual.pdf

i think i found the problem. The inverter seems not work properly with 12S lithium Batteries like the 2x6S configuration from the Tesla Model S i used. I noticed that the Inverter often shut down when the Battery was nearly full at around 51Volts, even though it would accept that Voltage in the...

any conclusion here?

I just installed my new EG4 6000XP inverter connected to 2 used Tesla model S battery modules and about 5KW of Solar panels. Have been able to connect the inverter to the new JK BMS, charging algorithm works flawless as far as i can tell. ( Battery Model 2 in inverter settings) The inverter is...
