Many people misunderstand the manual. I have a Balmar and this 18 minutes is confusing as it is modified by another parameter which lengthens this time dependent on how long it takes to get to the Absorption voltage. So it can take hours at Absorption or minutes.

The battery is not charged when the Boost voltage is reached! The charger needs to stay at Boost voltage maybe for several hours before it drops to Float. Even at Float the battery will still be charging for several more hours. All the time in Boost and Flot it will switch on and off to keep the...

Why Are My Water Pipes Vibrating Randomly? | ESTES SERVICES Some harm will have been done because with batteries disconnected their voltage will have slowly fallen from about 12.8v to 12.5v or less because of self-discharge in the electrolyte, which then causes lead sulfate crystals on the...

Their current brochure uses exactly the same description as to how the unit works..... "We put a "load" on the alternator to pull the alternator voltage down. This fools the alternator into thinking that there is a major drain on the system and as such, the standard regulator works at full...

On the face of it is a very clever idea to save the cost of having to modify the alternator, or buy a new one, but it is very very inefficient in electrical terms. It just puts a heavy load on the alternator to lower the voltage and sucks as much current as it can and then amplifies the voltage...

Charge efficiency has been mentioned twice now and it is a very good reason why battery monitors cannot be 100% accurate - no mater what the age of the batteries. Battery Charge Efficiency is not to be confused with battery Charge Acceptance which is the amount of current that a battery will...

I really have to challenge this because it is full of errors. After 42,340 posts I expect you to know what you are talking about. Simple - wrong - It has a very clever algorithm that has about 260 variables that it evaluates by reading the voltage over 1000 times a second. It learns the...

It may be easy for you, but not for most readers here. You have to do a capacity test by discharging to 10.5v at the battery designed current draw, and you have to maintain that exact current draw by turning on more loads as the voltage falls. (Ohms Law) and you have to do this for 20 hrs...

Yes it will give an accurate SoC but only when the batteries are new and the BM is programmed with the correct information. The information needed is the Ah capacity of the bank, the Charge Efficiency of the batteries, and the Peukert value for the batteries - this modifies the calculated Ah...

You seem to have been asking all the right questions and done the right things - but maybe not exactly right!!! This is such a common problem where a small amount on knowledge leads to a lot of confusion and a lot of errors. Trojan are one of the top deep cycle batteries so you either have...

To try and stop the bull.hit that is spoiling this thread I have e-mailed Victron and described my reverse polarity light illuminating with just a 5v Earth/Neutral voltage that I get in old marinas. I hope people aren't still calling this a 'fault'? I've also asked them what is causing the...

This is only your opinion. I see it as just pointless semantics which only ruins threads. Put simply the Multiplus is in Series with the shore power as opposed to in Parallel. Most Inverters are wired in parallel with shore power which is why this is a difficult concept for many who don't...

You need to appreciate the the Victron Multiplus is wired exactly as Vic describes. It synchronises itself to the incoming AC phase so that its output is the same so when needed it takes extra power from the battery - eg. if the shore power can only supply 16 amps and the boat demands 20 amps.

Thanks for the link - diagrams certainly help to explain the situation. Many thanks for your very detailed response. I suspect that my 'fault' may be my Victron Multiplus Charger/Inverter that is wired in series with the AC mains and senses the earth/neutral 8v imbalance and is not happy. I...

You initially said - I think you have a fault - now you know I have a fault - WHY? You can't keep posting the same thing without explaining where the error is in my detailed response to you. ​Most of your other posts are in the Lounge - you are not known for your knowledge on electrikery.There...
