Basic UPS battery safety best practices

It seems like the EcoFlow systems are starting to get support in NUT too, and the river 3 plus specifically has a merged PR.

This is great news for sure, and should make it a viable option hooked up to a network wide nut server setup.

Looks like goldenmate is adding a version of their battery backup with communication capabilities for automated shutdown.

I own one of the goldenmates, I agree - very basic, no data readout, but it’s been quite reliable.
Anyone have suggestions on lithium based UPS’s I can get mailed to Puerto Rico? Goldenmate wont ship :confused:

Anker Solix C300 (or larger)?

46

I recently picked up a Solix C300 to replace an aging APC UPS unit.

Pros:

  • The Solix is smaller.
  • The Solix has a light on it, which can be controlled through the smartphone app (bluetooth or wifi connection). Nice when I’m working under my desk and trying to read labels. The light has various brightness settings.
  • The Solix tells me real-time power usage. Previously I had hooked up my Kill-A-Watt to check what the APC unit was pulling.

Cons:

  • The Solix needs a power strip to support the 4 devices (1 tower, 1 Dell SFF, 2 NUCs) I have on my desk here.

Running for a good 48 hours, so far so good. :+1:

I’ve disabled most of the “fancy” features as they are designed for if you’re using this thing as a portable power bank. I don’t want the AC outputs to ever shut off, so turning off “Smart AC Output Mode”.

Almost two months later - this thing is great, haven’t even thought about it since install.

I was similarly impressed by what I had heard and read about these units. I now have a smaller one for the network stack and a larger capacity for the hypervisor and NAS. They replaced two APC UPSs that were due for new batteries. No real complaints so far although I miss the UPS integration and comms that were possible for metrics and alerts.

Did you try this yet? My experience with trying to put two APC UPS was not successful. Even “pure sine wave” UPS could not pass the power quality check. Limiting the input power to the downstream UPS could be helpful.

Either this or plugging a smaller UPS into larger one My best guess was that they were too electrically noisy as either a source or load or that the demanded charging current tripped the inverters. possibly work.

I never picked up a Goldmate unit so was not able to test if this would work.

Has anyone found any good solutions for rack mounting these lithium power stations from Anker or Ecoflow? I’m redoing my network setup and a clean rack-mount solution plus a better power system would be a nice reason to upgrade.

I bought one of the Goldenmate 1500 VA / 1000 W UPSs. It seems to work well. Its pretty quiet for the most part, it occasionally makes a faint, low hum. The display is nice, but I haven’t figured out how to get it to stay on. It has done its job through several short power outages. The biggest surprise was how big it was. The APC 1500 VA UPSs I’ve had in the past were fairly compact, but this one seemed easily twice the size (volume). The dimensions are: 16.73"D x 6.3"W x 11.81"H.

I didn’t realize how much power printers take, but I plugged in my small brother laser printer, it made an overload alarm come on the UPS (but it didn’t drop load, it was on line voltage). Steady state and printing its uses very little. So I will probably only plug things that are absolutely necessary into the UPS.
