I've been an AGM guy, but the last quote we did, it was about $777 for just the AGMs and $900 for LiFePO4 with everything in a neat and tidy rack-mount box.

But the other network engineer I work with prefers a dedicated PSU for each load. So you may not get a uninamous recommendation. Note I tend toward DC sites and other guy sees that as unnecessary expense and hardware. So if you are doing AC sites, maybe don't listen to me. And I'm still using AGM batteries while all the cool kids are using LiFePO4 with BCMs, so definitely don't listen to me. ---- Original Message ---- From: "Steve Jones" Sent: 4/26/2024 1:49:48 PM To: "AnimalFarm Microwave Users Group" Subject: [AFMUG] DC power supplies in parallel I have a bunch of various meanwell 48 vDC power supplies mostly 120 and 350 watt models with most loads being 45wattish and some 108wattish. One site im re-cabling has 1100w in PSUs taking a ton of space providing for a total demand of around 440w. Seems overkill and only accounts for the DC direct powered stuff, not the other 300w or so Whats the consensus on an AC powered site? individual PSUs for ever equipment. Big PSU/rectifier for all? Our battery capacity at this particular site is on the APC at the base providing just AC to the top, we are not bringing the batteries up for reasons and all electronics are up top. -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
