No, had a smaller Victron system. That fan was noisy too at higher loads.

Mine, before the ducts, were moderately noisy at 4kW solar coming in. (4kW here since I have 2 units, you have 1 I think)

Here is what I came up with. I used 2 layers of foil bubble insulation to make ducts that vent into the attic from the garage. This solution is great. --The garage is much cooler than prior (5-6 deg F), --The fan noise is much much less. I did not make dB measurements. --The cost was $32...

My 2 new 6000xp units will not go to float and I have yet to find an answer.

Yes, there is plenty of outlets in the attic. We have "off-ridge vents" and soffits here in Florida. I also have solar attic fans. I'm gonna give this a try and I will report back. Another advantage of the ducting is to reduce fan noise, which is a good thing.

The attic will be hotter than the garage most of the time but the forced air from the fans will still get that air moved to the attic. Let me know if you disagree. I plan to use a 6" diameter metal duct going straight up about 3 feet to get to the attic. This is the piece I would use coming...

Since that is the case, and I want to get the max power from my unit, I am thinking of building ductwork from the hot fan exhaust side of the unit up into the attic directly above. This should greatly reduce the amount of waste heat produced by the unit into the garage, which will keep the...

There does not seem to be any information I have found on how the EG4 6000XP derates its MPPT output or inverter output with elevated temps. However, my 2 units seem to be doing this since they heat up my garage in Florida to 95F as they run during the day. I do see that the data it records...

I lowered the price for the Multiplus2 3000VA 48V 120VAC to only $790

Has anyone else with a 6000XP seen this? Or even checked their system for it?

Jared, I noticed this error too. When will a new firmware update fix this?

No. It does not have the smaller, round vent holes at the bottom. It has the vent slots. The UL version is also 1" longer. Other than that and the certification, they are identical from what I've learned..

My 2 new 6000XPs are set to charge at 56.2V and 54.0V for float. No battery comm. Firmware is the latest. They get to 56.2V and then stay there until the sun goes down. They never go to 54V. It is damaging to the batteries to have them stay at the high V once full. That's why we switch to a...

Dang it! Next time....

I bought them all new and used them for about 1.5y without issues. They work great. No dents, no scratches. Babied. I have the original boxes they came in for shipping. Still under the 5y warranty. Multiplus2 3000VA 48V 120VAC $790 MK3 USB interface $45 Plus shipping. I am in the central...

I see this Start Quick Charge button on the webpage and phone app. No mention of it anywhere in the documentation. What does it do exactly? What max current does it use? I'd rather hear from you than just blindly trying it.

I am using the "self consumption" mode where priority is PV and battery with grid as a backup. I do not see a way to manually switch to grid when I am on PV/battery (and then back again). Is the only way to do it by setting the "AC first start and end time" values to non-zeros? If so, that...

So it seems that there are no "modes" that you choose from. Its just conceptual ways of using the system. They have room for software improvement.

Jared, how is the Working Mode changed? I dont see a way to directly select a Mode.

What was your solution?

What did you end of doing?

Dale, what is the status of your issue?

This does not sound as though the system firmware has been well engineered. I am reading here to evaluate the 6000xp and am not liking what I've been reading.....

Hello, When not using battery communication.....does the 6000XP have a setting to power loads from the grid when the battery SOC gets below some %? Then, back to battery once the SOC is above some %? I assume so but do not see this in the manual. As many of us know, using voltage to define the...

Yes, they get within 7mV or so when at 3.55V. The issue does not depend on the time but rather when the battery first hits 100%SOC for the day. Its looking like a problem with the BMS not consistently delivering the current. The next step is to replace it with another. Thanks for the help...

3s2p config, but thanks for checking!

All cells are being properly balanced as shown in the battery display. All connections are good.

I do not have another 48V inverter to test with but I would if I did.

I dont see how this could be an issue with the inverter, just the battery. How could this be?

Meter update is 0.5s or so. Smaller loads, <100W, drop V also but not as much. The cells are all in balance when this issue happens, which I can see from the BMS. I have run the system with the SCC breaker off, same issue persists. So, you'd say it a problem with the BMS ? That was my...

The alarm is from the Victron Inverter. The BMS does not give an alarm. There is no significant V drop between any terminals (SCC, inverter, battery terminals). Cables are only 1-2 ft. All connections are new, clean torqued. I've tried lowering the charge V down to 55.5 from 56.8, same result...

It is a "High DC Ripple" alarm caused by large voltage swings that the MPPT cannot maintain since the battery is not acting as a battery. So, bad BMS?

Setup: off-grid Victron 250/60 MPPT, Multiplus 3000W inverter, Trophy 48V/100Ah (installed 11/2022) Here is my problem -- To keep the inverter from having a “High DC Ripple” alarm and then shutdown, the battery cannot get to a self-reported 100% SOC. When it does get to 100%, it disconnects...
