Testing EG4 6000XP AIO inverter.

[Zapper77]

Thanks for doing all this testing for us @Zapper77 ! Seems the 6000xp is a pretty comprehensive unit. I also have one test if you don't mind. In the discharge settings, if you set Discharge Current Limit to say 50 amps and when running off battery and the loads are high >3000w and require more than the limit, will the inverter just shut down or automatically switch to grid bypass? This would be with the grid up and connected. Curious if I could hook this to a battery I currently have and get the PowerPro later this year.

It will switch to grid bypass.

I got a new one for you to test. I was testing the "AC First Start/End Time" settings and noticed something peculiar.
Start Time 1 = 19:00
End Time 1 = 22:00
This is prime TV, lights, dinner, etc power usage and we've had days of rain and gloom. So I wanted to use this setting to "bypass" back to grid for a few days to keep my batteries up.

I would expect it to switch into grid bypass at 7pm, which it did, and back to batteries at 10pm, which it also did. However from 7-10 there was also around 60w coming from the grid to charge the batteries for some reason. Note, no incoming solar during this time either. I tried it over two days, same result both times.

This is unlike when I fail over to grid using the "On Grid EOD SOC" setting I just get Grid = Load demand, nothing goes to batteries except any incoming solar. This AC First Start/EndTime setting has me stumped as to why I also see batteries being charged at the same time, unless there's a bug in the code.

Interesting. I kinda like the small battery charge amperage.

I’ve noticed my EG4-LL V2 batteries charging at about 1A when EOD (eco) has been triggered… I’m on latest firmware..

 

[Key77]

I have a 6000xp set up in an off grid cabin paired with a powerpro wall mount. At this point we only have one array finished with 1800w going to the inverter.

It is only powering a starlink set up when not at the cabin so I can monitor the system. We had a very cloudy period and it drained the battery below 20% which I had set for the off grid disconnect SOC. Inverter disconnected the loads as expected.

However, after 4 days (partly cloudy) the starlink hasn't came back online.

So does anyone know what setting would determine when the EPS switches back on after a low battery SOC disconnect trigger? Most other inverters I've delt with have a reconnect trigger point but I don't see any setting like that in the manual given it has no grid to charge from.

I don't remember the exact percentage but I'm thinking 3-5%, but that could be wrong...its been a while.

Same here. 6000xp charges batteries at 50-60 watts when no solar available and on grid bypass.

Thanks for your input, I think you are right. I just check after posting and the system had finally come back online showing 25% battery SOC. I have 2 powerpros hooked up so I suppose it can take a while for a little 1800w array to overcome the idle current and charge 5% during cloudy weather.

That being said it would be nice to have a setting to adjust this value to prevent short cycling with smaller batteries.

Depending on temperature...the BMS won't kick on until the heaters do their job.

Looks like that generator doesn’t have or allow 2wire start. Might need to find a compatible generator if you want any inverter to trigger generator start/stop.

Edit. Looking further into it, seems like that generator has something called a st switch that be hooked up to an extrtnal transfer switch. Might be able to figure out 2 wire start/stop with that, not sure.

This is my plan too. I have this generator now and see videos of folks using ST Smart switch to get it to autostart as ChrisG reports.. The contacts on the 6000XP work as youd expect and I am pretty sure this will work and already bought all but the the ST switch. I'll report back when I get this working. Also, I don't think you need a chargeverter between this gen and the 6000XP. This gen is clean enough without it and has a 7600W continuous and 10kW surge capacity.

 

[iannecj]

Thanks for the continued testing. Odd that it behaves differently if SOC under your start charge. Assume on the 2nd test when grid was available it acted like the previous test and powered loads and charged?

First, @Zapper77 love your videos and wanted to thank you for your moving collective knowledge forward. Also, if you answered this in your note to @ChrisG I didnt absorb it so apologies for asking you to repeat yourself.

Question: Can you gents make sense unexpected battery shutdown behavior for me?

Related Findings/Issue: When testing battery EOD/CutOff behavior and restart with gen, settings in XP dont seem to reflect behavior and there is risk of BMS undervoltage protect which I believe is not recoverable unless I use another seperate source used to bring battery out of UV protect.

Details: During garage testing before moving to my offgrid property, I have no AC input, no PV input, and simulate generator with a breaker which is tied to Gen Input. Battery is an EG4 48V100AH waterproof unit that is not serially communicable but does have bluetooth (bought this for sale price and WP feature attractive for parts of application (not be able to get to BMS not so attractive). . I asked CC to give me installer role in my account and this allows me to see more setting in app and on monitior.eg4electronics.com. Those settings are below. Note battery warning is set for test purposes at 50V and both discharge cutoff and on-grid EOD 49V. I am test loading with heat gun and toaster on one leg with between 1600W and 2800W of load on inverter. I would like to set both of these settings at even higher voltages for test purposes but ger error when I try to go higher.

I'd expect on a 1600W discharge to get a warning at battery voltage of 50V and the inverter to drop loads at 49V and 6000XP remain powered at very light battery load until PV or generator are available at input and then recharge OR battery depletes to BMS UV protect setting at 44.8V for this battery which ever comes first. By adjusting this setting I could leave alot of time before the battery would get to BMS UV protect was my hope and I could check on it,

That's not what happens.
6000XP will discharge to lower than 49 without any notice/warning on panel. In fact it will give me a notice around 46.5V and eventually drop inverter loads at much lower than settings at 45.3V ish In fact it will get dangerously close this battery's BMS cutoff at 44.8V. I would prefer to be able to set this up a good ways from BMS UV protect setting because if I hit that the battery BMS UV cutoff I believe I will need to use a power supply to get the battery out of BMS UV protect as I did when I received the battery meaning no restart possible without disconnecting the battery and a good bit of user intervention and I wont be often at this property.

Below find pictures of settings and the unit operating AC loads below these settings with and without low battery warning annunciated on front panel.

You may need to adjust for voltage sag under load. Can you try 51v instead of 50v?

What firmware version are you using?

 

[Quattrohead]

There are some great firmware updates being tested to improved generator functionality enormously. All you generator people are going to be very pleased.

Can you elaborate? Ability to limit use? My6000xp is being delivered this morning supposedly (come on FedEx!).

I've personally noticed that when I receive firmware for testing, that the public release occurs between 2-4 weeks after. So if all goes well end users will have the ability update in a few weeks.

Hopefully that includes a better, user intuitive, UI.

The LCD screen? Nope.

It may be nothing, but I’ve always had my discharge cut off below my on grid eod setting. From your pictures it doesn’t look like you have a grid connection, so not sure the on grid eod setting is even used.

The LCD screen? Nope.

Yes, the lcd screen. Another YTuber said a month ago that an update was in the works for it.
