I just installed my inverter with an EG4 wall mount battery, I liked the simplicity and how it worked right out of the box. My issue is that the fans run full out even at a light load (battery discharging 225 watts with the load being about 170 watts) and never stop running until I am pulling less than 100 watts. I have adjusted the fan speed settings from 20% to 100% and it has no affect on the fan speed, I have also done a firmware update, is this normal?

What version of the firmware did you install and how did you install it? Also I recommend you return to factory settings as a baseline.
ccaa-190D0E, installed as directed by Signature Solar through the website and wifi dongle. The technician said that there was no code that came up as a fault with the fans, they reset it to 70% but it was no change to what I had it set to. With approximately 300 watts of pv input and approximately 300 watts of load, it kicked on the 3rd fan, which was blowing at 100% (I’m guessing) as it was a bit faster than the other two, all were blowing cold air.

If I recall correctly there's an issue where the pv cooling fan runs flat out versus the ramping of the other two fans, not sure if that's fixable with firmware.

Mine does the same thing before the latest firmware update and afterwards. I have not tried to change the fan settings. The inverter is in my garage and therefore it does not bother me. I would be pissed if I had to live with the fan noise in my house.

I had read that thread, my biggest issue is the fact the fans never shut down if I am pulling over 150-200 watts, plus there’s no pv or other input. I could understand if I was pulling 1.5-2k, but 200 watts is such a low threshold for output. Also, having 300 watts of pv kicking on the 3rd fan can’t possibly be necessary, is it a poor design, a defective unit, or a software issue… and are Signature Solar technicians capable of handling anything except simple settings questions?

Hi! I'm so sorry you're having trouble with your unit! The team is definitely capable of more that just simple settings, however we do use tiered support. Have you been escalated to tier 2? I can get you reconnected, ensure you're escalated and taken care of.
I would appreciate that, I felt as if I was getting the run around with the technician I spoke with yesterday.

I apologize! If you'd like to dm me with your contact information, I'll get you connected.

That seems more than my two 6000's do. What kind of temperatures are you seeing? The local app doesn't display that but maybe the web version?
After 2 business days, no word from a tier 2 technician from Signature Solar as promised. Very disappointed they didn’t do as promised. Are the fans supposed to run continuously when pulling less than 200 watts, and are the fan speeds actually supposed to change when you change them on the unit?
At least my 6000XPs are set to "slope". They do change their velocity and ramp up depending on the load and PV production. Keep in mind that the fans for PV are different than the one for the inverter side. So, when PV production is high you would see the lower fan ramp up to full speed and the two upper ones at approx. 500watts or less are basically stationary.

Where is your inverter installed? If your fans are running more than other inverters then either the inverter "thinks" it's running hotter than it is or it is running hot. It's not the design or the firmware as mine has the same firmware. Also is any charging going on? Either solar or AC?

I’m so sorry for the misunderstanding. After listening to your call with Tyler, it seems he mentioned that he was asking a Tier 2 technician a question and would be right back with an answer, during the call. It doesn’t appear that he indicated the issue would be escalated directly to Tier 2. When I escalated the issue, the team gave it to an experienced tier 1 technician as it did not warrant a tier 2 to troubleshoot.
From our understanding, the unit is functioning as intended. However, to confirm this and ensure you get the most accurate information, I’d like to connect with @EG4TechSolutionsTeam for clarification on the fan speed adjustment and operation.
I truly appreciate your patience while I work on getting confirmation and a clear answer for you. I will follow up here with the response from EG4!

My pv fan does ramp up to full speed when it starts getting input, im not sure what the threshold is for it to run continuously, as we have been socked in by the clouds except for one day, since I have installed it. But the top two fans never shut off once my system starts pulling 150-200 watts.
It’s located in a cool location, no charging occurring, we are completely off grid, last night I was running a consistent 192 watt load and the 2 upper fans never shut off until we turned in for the evening and lowered the load to around 60 watts.

Yeah mine doesn't do that. I use Solar Assistant which shows the inverter temps. My fans cycle on and off depending on load and charging. All three on heavy charging or load but are often off completely when only lightly loaded.

EG4 got back to me, they're looking into this for us and will be coming here to comment!

Good morning!
@Seaward Please send us a DM with your inverter's serial number so we can look into this for you.
This is when the fans should be turning on for the 6000XP.

This is when the fans should be turning on for the 6000XP.
- When charging/discharging power exceeds 300W: Both left and middle fans activate.
- When PV power exceeds 300W or load consumption exceeds 5000W: The right fan activates.
The fans on my unit run continuously with loads under 200W. I DM you on my unit, looking forward to seeing what you find out.

Understood! Thank you!
EG4 now is trying to pass my fans running constantly, as being normal, even though it is significantly below the parameters they laid out in this thread. Inverter is in a cool location, blowing cool air, no pv or other input, and constantly cycles up and down without stopping between 120-150 watts and runs full throttle above 150W. Not a hint of heat coming from the fans. Also they refused to acknowledge that the fans speed option on my unit is non responsive. Plus now after connecting my generator input, the unit won’t allow any more than 1100W of input. There’s 3 settings on the inverter that can affect this, and the Signature Solar techs are at a loss as to why it won’t do more.

Does the EG4 website show the inverter temperature? I can't remember as I don't normally use it. Solar Assistant does which is what I use. It would be good to know if the inverter "thinks" it's running hot or if for some reason it is. You might remove the grills on the right side and temporarily take out the filter material and see if there is any change.
