    EG4 6500ex with Lifepower4 rack under performing

    So this is very interesting and likely the problem. I had the inverter setting 2 to 70A. Now it is set back to 10 on two separate but similar installations. This sounds like something is forcing the inverter to limit the amps at 10A and that seems to be what I'm getting. Anyone know what might...

    EG4 6500ex with Lifepower4 rack under performing

    Damn I love this site and all you guys who will help out. I think you may have gotten the issue. I went to Solar Assistant configuration to show you the settings and saw that it had max charging amps at 10A. My EG4 6500ex have setting 2 at 70A. Strange this is in conflict. Can Solar Assustant...

    EG4 6500ex with Lifepower4 rack under performing

    I doubt it is high as I have it in an air conditioned room. However, how do I get Solar Assistant to report that. Right now it says "no data". I just checked and can't find a place for the inverter to tell me either.

    EG4 6500ex with Lifepower4 rack under performing

    Ok, so I would call that 9s per inverter with no parallels? That is a testable hypothesis. I will give it a shot. Get 8kw running and see if the solar will support it. I'll be back to you.

    EG4 6500ex with Lifepower4 rack under performing

    I have two similar systems at two different locations that are acting the same. I'd love for someone to tell me what stupid thing I'm doing wrong. 36 panels 9s4p generating about 350v to 400v and rated for 455 watts each panel (ideally would add up to be 16kw) Panels are due south without...

    Confused about 6500ex programs 12 & 13 voltage

    I have two similar systems: 4 EG4 6500ex 10 EG4 Lifepower4 batteries 36 SolarEver 455w panel (9s4p) Generator backukp and 4 EG4 6500ex 6 EG4 Lifepower4 batteries 32 SolarEver 455w panel (8s4p) Grid backup On the second system (grid backup) I was getting error 61 when I read that setting-5...

    EG4 read/write cable

    I'm stumped...perhaps someone can shed some light. I have a USB cable and I'm fairly certain - from Signature Solar tech support - that I have the RJ45 end correctly wired with the black on pin 1 and the red on pin 2. Their old cable used the green and white pins but that evidently doesn't work...

    Switch between Grid power and Solar power AND use grid backup

    You've gone a little beyond my paygrade, but I think I understand the idea. Limiting the inverters charge rate from the grid/gen would work as long as it has two settings: one limiting the grid's max and a different one limiting the PV max. Obviously, I want the PV max to be as much as the...

    Switch between Grid power and Solar power AND use grid backup

    Thanks both of you for your comments!! I can't see the png image in Hedge's comments, but I've considered the interlock solution. But as you mentioned in your reply quoted above, it seems to me that charging the batteries at the same time as servicing the house would, almost by definition, be...

    Switch between Grid power and Solar power AND use grid backup

    Can you point me to the transfer switch you are referring to?

    Switch between Grid power and Solar power AND use grid backup

    I am building two homes that now have two similar solar systems. Each has four eg4 6500ex inverters (with pv and batteries, of course). One of these two systems is backed up by the utility and the other by a generator. My question is basically the same for both utility and generator backup...

    Confused by 5 awg wire supplied with EG4 48v battery

    Thanks everyone for your input. I see now, from the form filled out on WireSizeCalculator.net, where my error was. But, let me ask a different question then: Why pick insulation "open air" as opposed to "cable"? I chose cable and it leaps to a different gauge. What is the difference between...

    Confused by 5 awg wire supplied with EG4 48v battery

    I've just received a eg4 LifePower 48v 100ah battery. The spec sheet says it will serve up to 100 amps continuously. From wire gauge calculators 100 amps requires 1 AWG copper wire. However, I see the wires included are 5 awg (and I see everyone online using these supplied wires in their racks)...

    Planning new residential system

    Thanks for that chart!! I am not in any way practiced at this. I'm essentially winging it. However, I've thought a lot about it and this is my reasoning. I'd love to learn anything you can clear up. You said, 26kW output can deliver 216 amps. That is excessive for the house, but half of that...

    Planning new residential system

    Hi, I didn't even see this message come in. Sorry for not answering it. This is Brice in case we know each other. I'm actually building three places right now, but only one am I reporting on here as the other two will be mostly similar while hopfully working out the kinks. My main home I'm...
