here is a link to the actual device: they say you can use on of those portible cars batteries and can get about 30 hours on it. I just ordered for of the tunze 6105.50. also here is a link for the battery backup infoI am planning on getting the Tunze 6105 and the controller.
I noticed the Tunze site has a device that would divert power from a DC source in the case of power outage. Has any one used these or have a better option?
thanks guys. I think i will get one. any suggestions on batteries and chargers?
Wes do you need two safety connector one for each pump and could I hook up two pumps to one battery. Thanks for the information
wes, which battery would you recommend for 4x 6502 pumps and how long will it run the pumps, also will i need the same charger you posted for the larger batteryyes you need a safety connector for each pump. The safety connecter only has an outlet for one.
Wes
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.
The "Safety Connector" i have one. it's great! use it with a Sealed Lead Acid Battery connected to a float charger thats always plugged in and you have alot of backup time. The float charger will only charge the battery as it's needed. I like this better than the vortech battery backup because this connector gives you the flexibility of using any DC source you like.
I use this battery on a 6101 with a float charger...An estimated backup time of 55+ hrs. Im not sure about the 6105, but according to Roger from Tunze, the 6101 uses 12w on backup and runs about 1 hr per aH on a fully charged battery.
The Sealed Lead Acid battery is safe for indoor use and good for this type of application.
