Most rectifiers for “float “ service have current limiting. And yes the batteries will present a heavy load and it will take some time for the voltage to come up. If the lvd reconnects the batts the voltage could drop so much they will disconnect again and flop for a while. You need a rectifier that can pull the live load plus a heavy charging current. I would go twice my load or more for this reason. BTW not a fan of lvd. Do you really want to totally kill your customers in the unlikely event the bats go that low? I quit using them 20 years ago and have never regretted that decision.
