I purchased a dual EG4 6500 Inverter system from Signature Solar in December of 2022 and they sat unopened in my barn till November 2023 when I was finally able to get them installed. I also ordered a Load Center for the dual EG4 6500 system a few months before the install. There were other items in my order and install, mainly batteries, but I'll skip those for simplicity here. After the install the system seemed to be working OK, except I was having a problem with flashing or strobing lights in the house (dirty power?). Support said I needed to upgrade firmware on the EG6500's so I did that on both inverters, but that didn't fix the flashing lights. Then support said we needed to do some "gound bonding" work, which my installer friend understood and performed that work, but again it didn't fix the problem -- I think these steps improved the lights-flashing a bit, but didn't fix it. The flashing is not consistent either: sometimes the lights appear steady and OK, other times they flash a little and sometimes they flash a lot. I took a video to show a couple examples this past weekend (I sent these to Signature support):
Generator Issues: I have a high quality 20kw backup generator (1800 rpm, liquid cooled, Onan, has worked flawlessly for years) which was connected during the install, but later when the generator was tested, it would start up and run OK, but the EG4 6500s refused to use its power to charge the batteries. So we reported this problem to Signature. They verified some system settings and we sent them this video and they then agreed that the primary inverter is defective:
Signature's proposed solution: I am to return my two defective inverters for store credit, rather than giving me a refund. But store credit doesn't help me buy a replacement inverter (their EG4 18K), which I have to do before returning these defective units that are currently installed. In order to use their store credit proposal to help me pay for the replacement inverter, I'd have to remove the current eqpt, ship it to them, buy the new Inverter and apply the "store credit", they then ship that back to me and all this time I'd be without power. With their proposed store credit "solution" I either have no power for several weeks (too ridiculous to consider), or else I wind up with a large store credit that I doubt I'll ever use. They sold me defective equipment and they won't even try to reduce my pain a bit by offering a refund rather than a store credit -- of course I wouldn't expect to get the refund until the defective equipment is returned to them later, after the new inverter is installed. It's also an out-of-pocket issue that they want the secondary inverter returned as if it is A-OK, with me paying shipping and a restock fee, despite the flashing light problem shown above, which I believe it is partly responsible for.
Unhappy with their proposal, I asked for the contact info for the supervisor of the support person who seemed so insistent on the "store credit" proposal. He said his supervisor is on vacation till Jan 16th and gave me no contact info. On the 16th I sent him a reminder, but never heard back. Nothing on the 17th either. Today is the 18th and I've heard nothing, so I decided to post this and share my unhappy experience with my EG4 inverters and SignatureSolar.
