UPS recommendations

[astones153]

Any recommendations for UPSes in general here? I'm looking for something that will run an estimated 180-ish watt load for about 15 to 20mins whenever theres a power trip due to heavy storms. Afaik the "reputable brands" we have locally in Singapore are Eaton, APC and Prolink, and I've been searching up and down for any long-term reviews but to limited results.


Interested to hear your experiences with any of them if you've purchased and used them. How well do they switch over to the batteries when the power goes out? Whats the expected life cycle of the lead acid batteries? I've scoured reddit and they all seem to unanimously agree on Eaton being the most reliable brand. I'm willing to spend up to $300 on it, because I plan to connect my ONT, Router, PoE switch powering a wifi 6 AP, and a mini pc homelab to it and I wanna keep it running for at least 15 mins when the power goes out (which isnt very often, but still happens). I mostly just want to not worry about damage to these electronics and maintain internet access while the power is down. My initial plan was to slap together some Lithium Iron Phosphate (LiFePo4) batteries with a solar charge controller+inverter and run that as my main UPS, but I know I am nowhere near skilled enough with any kind of electrical engineering to attempt that, and any ready-made solution will cost in the thousands.

Just get an APC-UPS from online store. Preferably with local warranty.

If you need the system to properly shut down on its own after a certain period of power lost, get one with an USB communication port. To do that, your network equipment (usually the router/firewall) must also support features to configure the UPS.

An example of a UPS configuration page on a firewall appliance with properly setup notifications:

Which brand of UPS have cheap or long term battery replacement support?

Also is it a must to get pure sine wave over simulated sine wave for desktop ups?

None I know of for home users. Your warranty (or support) likely over when the battery is due for replacement. You can go with some model of UPS which you can replace the battery yourself. But I suggest only for the know how. Recently, I will prefer the rackmount UPS series from Prolink over APC.

For home users using OTS desktop PSUs, I dun think you need sine wave. For those who run mission-critical or high powered servers at home and deploy hot-swappable server-grade PSUs, I think it should be a must; otherwise, it will likely cause disruption during power switching.

Example of server-grade PSU:

Yeah, I'm confused about the simulated vs pure sine wave. Asked chatgpt and it said those psu with active pfc require pure sine wave, else will cause issues such as desktop not able to switch and causing shutdown in the end.

I'm looking for line interactive UPS that output pure sine wave. Unfortunately in Singapore, CyberPower not selling the CP1600EPFCLCD model that I found that is cheap and fit my criteria.

I'm hesitatant to get double conversion or online instead of line interactive because I think double conversion don't last and are less power efficient.

This apc match my needs but need import from Korea... https://s.lazada.sg/s.g7SIa?c=v&t=p-i3tbqW5-sPjlFub

I find the lack of replacement battery sale troubling for apc ups.

Seems like prolink does sell replacement battery

Can consider this model from Prolink. Also comes in 1KW, 2KW and 3KW models or more:

Does anyone know how to find out which non-official battery can replace the OEM battery ah?

For example, 9ah for APC battery such as APCRBCV203

https://www.se.com/sg/en/product/AP...ery-cartridge-vrla-9ah-24v-dc-2year-warranty/

how to see and match to buy cheaper non-OEM/official battery from elsewhere?

can use car or motorcycle battery to replace UPS batt??
