Welcome to the battle front Cliff! I remember we spoke on the phone early
in October. Good to know that the list is recovering from sign-off

I once connected 4 90AH batteries to an APC BACK-UPS600 and it worked
beautifully. Powered our server for one year before lightening fried it
and the cyclades multi-I/O controller. I am not sure Jos beats Ibadan in
My company does make and sell very nice UPS systems adapted for Nigerian
conditions (Randomized White-out, Brown-out and Black-out). They are 3KVA
beasts packaged in Baby AT cases. A cage on tiny wheels holds the 8 of
60AH batteries, configured in a series parallel configuration to give 48V.
In my office, we have 12 Clones running off it, giving us close to
2.5hours of backup time. The Server runs off another (1.2KVA version) that
gives it an all-night protection. We are discontinuing the 1.2KVA version.
Power availability in my street (Best performance) is 4Hrs on, 20Hrs off.
Asking price? N120,000 for the 3KVA, and N60,000 for the 1.2KVA. For our
International friends, At 85:1 - that is circa $1400, and $700.
