Voltage on battery backup for sump pump Bluetooth#

I must have missed it, but I read the input range on the phoenix inverter as up to 17 volts, which would be within the output of the charger at 15.8 volts? So maybe no reason to worry? I'm also concerned about running into some trouble by having the charger connected at all times, specifically in regards to the protection against high voltage and 'DC ripple too high?' The latter being something I briefly read about in another post, so to be honest, I'm not really sure what exactly this is all about.

Voltage on battery backup for sump pump Bluetooth#

I do plan to get the VE.Direct to Bluetooth accessory to be able to use this functionality. I hope that the adjustable low voltage shut down would be able to protect my battery from dipping much below a ~50% charge?įurthermore I trust the dynamic cut off functionality would prevent false shut downs from loads etc? How would all this play along with the 12v Victron Phoenix 1200VA inverter? 15A max, supposedly rated for lead acid batteries up to 300ah. Varta dual purpose 12v 240ah sealed lead acid battery.(* The main pump is on the grid, so this one is purely for backup and only powered by the inverter, and will be mounted in way so that it only kicks on if the main pump fails) The setup is as follows: ( I already purchased these items)

I know my way around the basics, but lack experience and knowledge regarding all the more complicated aspects concerning off grid power. I thought I had everything figured out when I purchased all the necessary equipment, but just before connecting it all, it dawned on me that the inverter in got only shuts off at a battery voltage of 10v, which would ruin my battery. It's crucial that we get a battery backup for this system in case of grid failure, which are rare but do happen, I also need a backup system in case of mechanical failure of the main pump. I have a 550w sump pump in the basement, which runs for ~40sec every ~10 minutes or so.

Hi, I'm hoping there might be some bright people out there willing to help me out with my project.
