I’m tired of buying a new 12 V battery every 1-2 years. I have about 4 small (rated ~ 300 W [not VA]) UPSes with 7 Ah, 12 V, maintenance free batteries.
I’m thinking about replacing them with one, powerful unit. But the more powerful the unit, the more it costs - non-linear.
Do you have experience with some DIY solutions? Like 12V DC to 230V AC inverter, battery charger, some UPS controller (simple relay?)?
Or maybe you have some other idea that is cheap(ish)?
Not only is a DIY UPS unreliable, but it could be potentially dangerous unless you are an electrician, an electrical engineer, or somebody that has extensive knowledge of both the engineering side and safety side. How many CyberPower units do you have? It’s impressive that you have enough UPS power to run a NAS for that long.
I have 3 - but I get that runtime out of one of them. Depends on load, but idle the nas doesn’t draw too much.
What’s the chip in that NAS?
Quad core atom I believe
That makes a lot of sense. Great low power chip.
What is your NAS? Is it something you built or a Synology?

Ah, I thought as much because they’re really power-efficient unlike something DIY.
