Hi, I've got a battery back-up system for my Harman pellet stove. Works like it should, no problemo! I've just acquired a Fahrenheit 50f furnace and it's not behaving like the Harman, ditto! Here's the set-up I have; Iota 30A tranfer switch, TBS 600-12 puresinewave low frequency inverter, Cotek charger and two Trojan 6 volt batteries in series. The pellet stoves and a light is connected to the system. The TBS inverter has a Automatic Standby mode(ASB) which checks every second for a load to automatically turn on. Works well with the Harman stove which a slight dip in electrical supply doesn't stop it from continuing running. But with the Fahrenheit furnace and a slight dip in electrical supply, the furnace goes into a shut down mode. Not fun to come home to a cold house with the furnace down. There's a remote switch on the inverter and I tried hooking up a fail close(on) relay but the furnace still shuts down. I was thinking of adding a capacitor set-up to buy me 2-3 seconds of electrical power to soft shut the power but giving my inverter time to kick in before the power dips or stops. Can this be done? Or suggest something else? Thanks in advance
I would think once there is a call for power it would kick on. How would adding a capacitor change it? I see capacitors for stored potential... but... does your inverter meet the required specs for the furnsce blowers draw amount? I skimmed it sorry . I am an electrician on locomotives for mostly DC power but the newer ones are all AC. Still learning as I'm relatively new at it..
Most inverters will have a threshold setting for the ASB. Maybe you can turn it down? Or, if the problem is that the Fahrenheit shuts down when the inverter goes into standby, you might consider a small battery or rewiring a DC feed to run the Fahrenheit's logic circuit. Usually those are DC, and you might be able to directly run just the logic off the batteries rather than the inverter, then just use the inverter when the bigger AC loads kick on in the furnace.
Should this be in the D.I.Y forum? I'll put it up there and see if more activity i Stored energy to buy time for the inverter to come on and have a smooth transition with no dip in power is what I'm trying to achieve.
Unadjustable. I can had a computer ups but not enough durantion(3 minutes or so). Pigging back them together wouldwo4k but not recommenďed. Tampering with the control board could lead to undesirable consequences, sounds like a way to make it work.
