Power cuts

Nice setup, you were running 3 tanks on your system. Would you suggest the same UPS but less batteries for a tank setup.

Actually 4 tanks. But excl. lights, chillers and all but 1 heater. Cannot use fewer batteries - 5 are needed to provide 60V.

On your website "It has five 102A, 12V batteries"

Are these car batteries or Lead Calcuim batteries (ouch - expensive)

Dunno. It is the Deep Cycle Deltec 1250 batteries. I paid R998 per battery... So is it Calcium?

The UPS is there to convert the 60V to 220V pure sinewave, to handle brownouts as well as blackouts, to perform buck and boost (AVR) compensation - and automatic switchover. The batteries support the UPS - not the other way round.

The UPS, is that only to regulate the power from the batteries then?

It does regulation but also auto switches when the AC power is down. Te unit is also inverting 12/24V to 220V.

In my case 60V to 220V. PS: It looks like the batteries are Lead-Calcium.

Those are lead calcium batteries.

hi guys and gals hope u all had a good christmas and new year, and are are all ready for a heavy year with eishkom's power cuts.
I have heard about a smaller electric generator which is plugged into a normal 220V and kicks in when there is a power cut and runs for average 5 hrs and when the power is on again it recharges. Has anyone heard or seen about it they are about R4000 and are suitable for the tanks. My father has only seen them in Jhb not in Dbn.

hi guys this sounds like a ups
mekaeel im using a 3kva ups which can run my tank for 7 hours

How about this:

APC Smart-UPS 2200VA 230V - R 6 - 7K

4 x M1100 powerheads = 60 watts
2400 l/h return pump = 65 watts
no skimmer, lights or heater/chillers

Total power needed = 125 watts

at this consumption you would get approx. 4 hours usage

check this table for consumption times

Cool UPS

I have the 1000VA. Nice, but the battery is small. Not designed for extended run times. With my external battery pack on my other UPS I can run for 5 hours on 90% load - which is about 1800W. But it all depends on how long you want to run what equipment.

Likefish, your system is great and for extended hours ideal especially because everything runs as normal.

I was just suggesting a more economical back-up for power cut period 2-3 hours. Which have been scheduled for the next 6 months

so what would be the ideal UPS,just to run the return pump and 1 resun wavemaker and cost wise?
