Tunze/Power outage

[djay]

i have 4 of these Tunze 6105.5 Safety Connector

this will be for 4x 6205. should it be 12 volt or should i be looking for a 24 volt battery. can someone be more specific on how to hook these up to the battery

i'm looking at this, what you think

i was told by a good friend this will be the break down to the backup time i will have

"ok i looked up the 6205 = 55 watts

55wx4 = 220watts / 2 = 110watts usage on backup if all 4 are running at 100%

9.16 amps

98amps / 9.16 = almost 11 hours or backup time if all four pumps are running constantly at 100%

you will get more than that if the pumps are pulsing on a controller because they are not running at 100%.. for example using interval 1 on the tunze multicontroller would more than double the 11 hours because 2 pumps are only running at a time and they are pulsing.

i'd say 24hours is a good rough estimate if you are using them on a controller w/ interval setting."

At 12V the pumps will produce roughly half the flow they do at 24V and they will draw less power overall (about 25-30W). If you need the full flow you will usually need two 12V batteries running in series. I don't know of any 24V batteries. Usually big diesel trucks are 24V and they use 2 12V batteries in series. That charger is probably a bit of overkill. For how infrequently the system will be called upon a small 1 amp trickle charger that looks like a wall pack transformer is likely all you need.
