I wanted something to see the battery data without the need for a laptop or booting the Pi with Solar Assistant. So I decided to pick up the EG4 Communication Hub. Just spent a few hours trying to figure this out. EG4 manual is worthless. The last time I contacted EG4 and SignatureSolar about...

Well, I was wrong. The serial to USB cable turned out to be the issue. Received the new srial cable (SABRENT USB 2.0 to Serial (9-Pin) DB-9 RS-232 [FTDI Chipset] (CB-FTDI)) and the firmware updated on the first try without a hitch. Rebooted and the MCU and CPU are both up to the latest. The...

First time crimping using a 12 ton crimping tool and these types of lugs. Tested converting the 6AWG cable that comes with the EG4 batteries and M6 lugs to ones that use M10 for the bus bar I plan to use in the future. (I also plan to use larger wire gauge) On the first attempt the lug...

I submitted my serial number for a 6000EX I bought from Signature Solar. I’m interested in s trade in for the 6000XP but haven’t heard back. Is there a timeline for the upgrades?

Awesome! Thanks!

Thanks! I'll give the tape idea a try and see what happens.

Yes! Someone eventually called me directly and shortly after I had a PayPal invoice. I paid it, received the return label for the 6000EX and started to wait. It took a few weeks and I just received the 6000XP. I opened to box to check on it but haven't had time to test it. The unit's a bit...

I picked up a 50 male / 50 female set of "Amphenol Solar Photovoltaic 8 awg" on eBay for under $30. Worked great with 8 AWG wire using an AMZCNC 12 ton crimper from amazon. They connect fine to MC4 but from my understanding aren't going to pass any inspections.

I'm trying to update the firmware on the EG4 6000EX. I've successfully updated the remote display MCU firmware to 61.15. However when I try to upgrade the CPU firmware I get a message on the display "YES PG". I've tried to update with, without and from grid input with the same results. The COM...

Thanks! I believe I found your other posts where you (or someone) mentioned exactly the same. I tried that but I get the same message right after I reflash the display f/w; "YES [PG]". I only get the error 32 if I physically unplug the display cable and reconnect it. The inverter starts up and...

Thanks. That was my understanding, the fuse should burn out before the wire. But I feel like everything I read mentioned to increase the fuse size when increasing the wire size. L̶o̶o̶k̶s̶ ̶l̶i̶k̶e̶ ̶L̶i̶t̶t̶l̶e̶F̶u̶s̶e̶ ̶m̶a̶k̶e̶s̶ ̶C̶l̶a̶s̶s̶-̶T̶ ̶f̶u̶s̶e̶s̶ ̶t̶h̶a̶t̶ ̶s̶h̶o̶u̶l̶d̶ ̶f̶i̶t̶...

I'm hoping to keep everything inside the Lynx. The whole setup is mounted on a 24U rack and somewhat portable. The current setup works but I'm trying to tidy up the wiring. I may be able to drill out the JLLS Series 110-200A T-class fuses to make them fit. The center to center stud distance is...

I'm modifying a server rack PDU as an alternative to a Siemens Talon TL77US to use with a 3000w 120v inverter for a portable/backup system. The PDU is spec'ed as 240v and had an L15-30 plug; looks like it was designed for 3 phase. I'm debating whether to rewire it to only use the single pole of...

I'm having issues trying to understand the fuse size dependency on the wire size. If the breakers on the EG4 LP4's are 100A and I switch from 6AWG to 4AWG for batteries, would I need to increase the fuse size to protect the wire to 150A? From what I've read the fuses on the batteries aren't...

Are you using different size cables to each inverter? Do they mention that you can substitute cable length with size?

Great thread! I read the discussions in earlier posts on the EG4 ISC limit and how it would only cause an issue if theres a short circuit. I’m considering using four 48v 445w bifacial panels with the EG4 12k unit. The panels have a potential to provide ISC of 15A at 30% gain. I’m guessing...
