HI Gavin, hate to tell you but your LV6548 are just rebranded Voltronics units *JUST* like the EG4 6500. The physical hardware is the same, the biggest difference is that EG4 writes their own firmware on rebranded units so they can better support the unit. EG4 recently discontinued the 6500EX...

Totally agree with the EG4 manuals being terrible. They don't provide any context on how and when to use a specific setting. Here is something worth noting: EG4 doesn't make their own gear. They're more of an integrator of various other people's products. The EG4 6000XP really a rebranded...

They're not exactly the same, EG4 installs their own custom firmware on the unit to better integrate with their batteries. Whether or not they're physically the same, I'm not sure.

I can certainly relate to that. I struggled for months trying to get my stack of 8 EG4 Lifepower4 batteries to charge evenly while hooked up to a pair of EG4 EX6500. I got so frustrated with EG4's inability to properly support the unit, I did the upgrade program and now have a single EG4...

I sweared at my EX6500s and definetely didn't swear by them....

I dont know what else is good, but I will say to stay away from anything Voltronics makes. The units themselves seem ok, but if you do have any kinds of issues, the tech support they give to their resellers is absolutely abyssmal. I took a Voltronics Infinipower 6kw unit down off the wall...

It's not the 6000ex. The EG4 6500EX is a single phase unit and the voltronics 6000ex is a split phase unit, capable of producing 240V AC. Voltronics makes two versions of it's 6k split phase. One uses a high frequency transformer and the other one does not. The weight difference is at least...

They might have completely different transformer systems in them, which would account for most of the weight difference.

What is the relationship between EG4 and Voltronics? Why aren't EG4 dealers selling other voltronics units? And biggest question -- my EG4 dealer can actually support what they sell (more or less) but none of the voltronics folks can support their own gear. Can you point me to the...

I am trying to use mpp-solar to reset my EG4 EX6500 to factory defaults. I have set up mpp-solar on a Mint installation with a debian base and followed the ubuntu install instructions. Using a python VENV, I got everything installed. I'm using the factory EG4 USB serial adaptor and the OS sees...

So with everything I've read, should it be possible to use the serial cables directly to an older PC serial port with a 16550A UART and have it work ok? I know when trying to use the supplied DB9 to RJ45 cable that came with the inverter to update the firmware, the transfer would always bomb...

Perhaps try updating the firmware using a PC with a 16550A uart in it. If *should* have the proper voltages. I will try and test this myself maybe tomorrow and let folks know how it works.

Adding to this a bit, if your batteries aren't talking BMS to the inverter, the 6500EX will show the batteries as being very low and in need of charging. If you plug in your BMS cable from the fully charged battery chain to the inverter, it will show a full charge. I think this is because you...

I have a question -- will this command set Register #28 on an EG4 EX6500 inverter (where you can set the inverter to 2P1 and 2P2) back to default as well, which is a stand alone inverter and not a multi-inverter/multi-phase configuration??? Please advise!!

This is all good information, thanks for sharing. I guess if EG4 is developing their own firmware and not making any changes to the hardware on the unit, one should be able to run EG4 firmware on any of the corresponding units. Also if it's their own firmware, then they have to support what...

Signature Solar has a trade in program where they will give you $750 for the trade in of an EX6500. I'm kind of torn as to what to do. I really don't have the money to upgrade, but if I did upgrade, I am want to get the big 18k Sol-Ark with EMP protection. So, incremental upgrades are super...

Cha-Ching Cha-Ching! That's one expensive set up you got there. Nice looking professional installation too! It's be great if you could provide a parts list for everything, specifically interested in your ability to easily move circuits between grid and solar and then back again. I could...

if your strings are 8.2 amps or less, consider running them in parallel and run all four of your strings off the single 6000xp. I have older panels that are 7.5A and this is what I am planning to do once I get the other two strings physically installed.
