I have a 24VDC return pump & need a battery backup to keep it running during power outages.
The diagram below shows the AC power entering the pumps Driver, & 24.18V DC leaving it.
My thought is to place two 12V batteries connected in series in between the pumps Driver & the pumps Controller. The Driver will keep the batteries charged, & when the AC power cuts out, the batteries take over & run the pump.
So (1), is there any possible problem with this design?
and (2), the output from the Driver is 24.18 volts, & the batteries Standby voltage is 27 - 27.8 volts (fully charged). Could the higher voltage of the batteries damage the controller (do I need a voltage regulator in line?).
Thanks for any feedback.
