Even Smartgauge makes a VSR and the Balmar Duo Charge can be wired to work as a simple VSR. Blue Sea Systems is not the only manufacturer of “Combiner/VSR’s” and today the competition is actually quite wide spread including Yandina, Sterling Power, Victron, BEP and many, more. Wayne has been retired now, for at least a few years, and that number is now likely much larger. of Blue Sea Systems, a number of years ago, he suggested that over 500,000 ACR’s had been sold world wide. The Blue Sea Systems ACR’s (automatic charging relays) are one of the most common charge management devices in existence today. Unlike a diode type isolator, which causes an approximate 0.6V volt drop to the batteries being charged, the combiner/VSR’s were simple voltage triggered paralleling switches and both batteries could be charged without human intervention or the voltage drop associated with diode type isolators. Back in the early 90’s the first of the voltage sensing relays were hitting the market, thus no longer requiring the owner to do anything to the battery switch in order to charge both battery banks. Many a boater has succumbed to two dead banks due to what we refer to as HEF (Human Error Factor). However, when the owner stopped the boat the switch was often forgotten about and left in the PARALLEL position thus draining both batteries while on the hook. This was all well and good, charging in parallel, so long as the motor was running. The most ubiquitous of these methods was simply switching to the BOTH/ALL or 1+2 setting on a 1/BOTH/2 battery switch. In days of old a boat owner had to use the battery switch to route/direct charging to the bank or banks they desired to charge. It does this automatically with no human forgetfulness. You read that correctly, in its simplest form, all an ACR really does is parallel batteries when charging is present and un-parallel batteries when there is no charging present.
