Does anyone know how to use the dry contacts on an EG4 6000EX inverter to trigger a dump load? As described in the pathetic manual, the dry contacts seem to be for starting a genset to recharge the battery, the opposite of what I want. According to the manual, with the inverter set to SBU, the...

Timselectric, thanks for the note. When you say "sees a grid", do you mean that the inverter has to detect a 60Hz sinewave? If so, I wonder if there is any way to spoof it? Maybe a couple of megaohm resisters to couple the sinewave, but not any current.

This is long-ish, please bear with me. Thank you. Has anyone ever tried using the grid back-feed, or grid-export functionality in an inverter to power a dump load? First some background, then I’ll explain my idea. I built an off-grid solar power system using an EG4 6000EX inverter. I now have...

Note: you need to power cycle the batteries after changing the the BMS address (dip switch) for the new address to take affect.

I encountered the same issue and solved it by flipping the mounting ears. This moved the batteries forward just enough to reinstall the back cover

I use a Dymo Rhino label maker. Very durable. I labeled some irrigation equipment, which has been outdoors in the weather for eight years and the labels are holding up very well; no fading. Also, the label achieve is increasable. Once applied to a smooth surface, they will not come off. As seen...

Folks, The EG4 6000EX-48 does have an internal NG bonding screw for the AC output. Confirmed by SS tech support and my own testing. I did not attempt to remove the screw for fear of voiding the warranty.

Mr. galstaf, Regarding monitoring app and firmware for EG4 6000EX.... Here is response I received from Signature Solar while I was trying to get it to work. Hope it helps you a bit. In my case, I think I made the most progress after switching from a Win11 laptop to Win10 and getting a new...

Regarding battery addressing, it was my idea. I was an initial charge on my four batteries one at a time. Started at the top, set address to 000, charged it with solar, turned it off and moved down to the next battery, etc. When done with charging batteries individually, I end up with the...

Hello galstaf, Yes, I got the Solar Power app working, but it's pretty disappointing software. First I resurrected a Win10 laptop that has an actual CD drive (versus sharing CD drive via network). Then also bought a new USB-RS232 dongle with up-to- drivers. Once installed, I switched over to...

Oh jeez, get out now!

I recommend a small UPS meant for home PCs or small business. CPAP machines draw very little power and I bet a small UPS would last a whole night.

Just got an email from Universal Devices that they are dropping support for the ISY994i. That's the final nail in the coffin, I'm migrating from Insteon to Yolink.

jfpetesn, thanks for the lead. I have not heard of Yolink. With 1/4mi range it might just work for my remote switches. I will have to decide either to patch up my Insteon network or abandon it and migrate to Yolink.

BentleyJ – Thank you for the great insight. If I may paraphrase, you suspect that the inverter is generating electrical noise that is drowning out the PLC signals. Putting a TDK line filter on the input side of the inverter could do the trick. Please see amended diagram. You reminded me that I...
