RE: [datacenter] Backup power for small sites
To do a 100A (12KVA) Solar Panel Project, you would need roughly 1600 SQFT
of solar panels (that is also dependent on the amount of sun available) to
power it. This does not include the inverters or the batteries to get
through power spikes.
Fuel Cells are still very expensive.
Have you looked at a micro turbine. You can get 30KW 480VAC three phase in
a unit little larger than a closet. You can recover the exhaust for
building use. They can be used as Primary or Secondary power. Designed to
run 8,000 hours before minor maintenance is required. They might not be as
Cheap as you want, but they are a good alternative. check out the link. It
is to Capstone

Subject: [datacenter] Backup power for small sites
I have a small site I need to provide backup power for.
requirement
100A expandable to 200A
Non roof
I'm powering a backup NOC, computers, switches, a PBX, and
a OC48 MUX.
Anyone recommend a cheap option outside of diesel generators
and battery strings? Would solar or fuel cells be worth invesitgating?
I need 8 hours of backup at a whack, replenishable in the event
of a multi day failure i.e. >24 hrs.
I've only done it diesel. I could consider natgas, or fuel cell.
