The Anker support team confirmed that the F3800 throttles down to a 700 Watt maximum charge input when the batteries are below 15 degrees C (59 degrees F)!!! They do not disclose that limitation in any documentation. The 700 Watt max input applies to the DC input and the AC input. This is due to battery absorption limitations related to temperature and battery health. I am attempting to suggest to them that with a software change it should be possible to allow 1400 Watts when an external battery is plugged in since the external battery AND the internal battery can accept 700 Watts EACH. As it is designed now, each battery is only receiving 350 Watts each when an external battery is connected since 700 watts of input is distributed to 2 battery packs that could technically accept a combined 1400 Watts when under 15 degrees C. I’ll provide an update if I hear anything else from the Anker support team.
Interesting, I will have to check out mine, thanks for the heads up. I am sure there will be a lot of firmware updates as this is a new launch for them
@neilljones33 1 day ago I received one f3800 in December (part of Kickstarter) and the other f3800 in January (new order). Anyway I've experienced the problem you had with the AC Input being limited to around 700W. Through support at Anker i was made aware of the limitation to battery charging being a temperature issue. As part of the Kickstarter order I received two of the 400w Anker panels. My understanding is the XT-60 inputs can be used to charge the batteries while the f3800 is outputting to my load panel. I haven't tried the Anker Panels yet. My loads through the Reliance Load panel are modest...less than 1000w, most of the time less than 400w. I have the Home Power Panel on order, but won't be here until March. This in turn will supply my needs for the whole house, which includes Central HVAC. My question per se is having to do with the EG4 Chargeverter. I too have an old GENERAC gas generator of the 5500 running watts 8500 starting watts. I liked your EG4 Chargeverter you had set up. On the DC output you had a terminal pad where you connected cables to the XT-60 input of the f3800. I was wondering WHERE you got the terminal pad and the cables to the XT-60. I'm just guessing, but maybe the Anker Home Power Panel has an input port to plug the 240V AC from the GENERAC Generator. Meanwhile I need to charge the batteries on the f3800 either from the generator or the solar panels while the f3800 is running...
Regarding the XT60 DC input ports, it is apparently not possible to have both ports supplied from the same power source using a Y adapter. I also tried isolating the two branches with a Victron Argofet battery isolator but that didn’t work either.
Wonder if you could re-try your test at the 4:00 mark with the two separate sources on two ports (the Chargeverter and the Victron)? I just started testing my Solix F3800 with two separate 200W Anker solar panels on the two inputs, and I'm finding that the rightmost XT-60 port appears to "dominate" over the left XT-60 port, in other words if the right XT-60 input is active, my left port goes inactive. Either input works fine with one panel by itself, but my left port won't work if the right port has any input. So I'm wondering if your test with two sources still being capped at 700W was actually two sources, or when you plugged in the Chargeverter on the right port, whether your left port with the Victron became inactive or not. So if you could re-run the test with the Victron on the right port, and the Chargeverter on the left, would you only see 139W from the Victron and the Chargeverter not inputting at all?
I found the issue I was having only occurs at high SoC (around 92-93% SoC when I tested), when I tried again at 40% SoC both inputs worked fine together or separately. So probably a different "feature" than the 700W limit you're observing.
Try doing the reset on the unit (that little pinhole on the panel) I was running into your 700w issue and then I did the reset and I was able to charge at ~1075w on one input. Please note that I was not able to test charging via both inputs. I DID try it with two sets of solar panels when I first opened the thing and was running into some strange issues like only one input was working. However I haven't been able to test to see if the reset fixed that issue. But LMK.
Have you been able to resolve this issue? I was intending on using the solar inputs this way to be able to utilize the 240V output while charging without using the home panel.
I’m in the process of working through the issues with Anker support. As of now I’ve been informed that the two PV input ports will not support power from a single source. Also, apparently the F3800 will throttle to 700-800 watts if the battery is under 15 degrees C or 60 degrees F. I’m not happy about that news at all.

Anker has not notified me of a fix or workaround as of yet. I’m still hoping they will consider allowing more than 700 Watts input when the unit is colder than 60 degrees F. Particularly when an expansion battery is added.
I am having the same issue. I have solar panels connected to it but it appears I can only charge from only one XT60 input. I can push about 900W in from that one but as soon as I plug the second one, it turns both off. I have been emailing back and forth with the help center of Anker but so far no solution is offered. Please let us know if you come up with a solution.
I noticed on mine that at high SoC (93%, 59F when I tested), any input on the right XT-60 input would disable the left XT-60. It wasn't throttling the total, as I was only trying to push about 120W of solar on each input, and any partial or complete shading of the panel on the right input wouldn't allow any amount of power to come from the panel on the left input. Depending on the order of plugging and unplugging inputs, the relays can reset and power drops to zero, have to wait 3-10 seconds for it to detect power on each input, and ramp back up slowly from zero - so takes some patience to observe what's happnening. That all said, when I drained the SoC to 40% (battery temp now at 89F), both inputs worked fine with up to 155W per input (from a 200W panel on each input). I don't have any higher DC or solar power sources to test at higher watts.
Thank you guys for your comments. I am in the same boat as you, waiting for a solution via firmware update. I'll keep you posted with any new learnings. Thanks in advance for doing the same.@@warrenwu8559

Thanks for the video. Please keep us updated

It would seem the manufacturer is trying to protect your batteries, I suggest you follow their lead.
Any updates? im close to buying one of these for my mobile food truck business. but this glitch is somewhat of a concern.

Update the firmware from the phone app.
Yup. I’ve done that.
