Adverc

[lustyd]

Can anyone explain what the Adverc does? I have one and had pretty much ignored it but about to fit a bunch of new things including a B2B and Lithium battery and it feels like a good time to understand this other box! a half arsed look this evening suggests that it connects to the alternator and the house bank, which seems weird since the Adverc is right next to the VSR and switches so no idea why there's a wire going all the way to the battery terminal.
It has very thin wires so I'd be surprised if it's participating in the 30A charge from the alternator directly but I can't seem to find a useful doc on what it's up to.

 

[lustyd]

I am being a bit lazy because I'm sure someone here will know. Otherwise I'd trace the wires and do a better search for info

It is an external battery sensed alternator regulator

The vsr will be doing its normal job of charging a second battery.

I assume the Adverc should be sensing the battery to which the alternator is directly connected.

I had assumed the alternator was directly on the engine battery. So how does it regulate, does it connect to the alternator and control it somehow while the power goes through other cables?

I will end up tracing wires tomorrow but would be good to know how it works when I do

I have one - fitted several years ago. Charges both house & engine battery. Works fine, no problems with it. I do have the instructions at home but am away for a week at the moment. I could send a copy to you when I get home?

 

[lustyd]

Thanks might be useful. It doesn't have cable thick enough to "charge" anything so VicS seems to make sense in that it controls alternator output somehow. My alternator often pushes 30A and the cables seem to be 1.5mm or maybe a little thicker

An alternator produces charge only when a current flows in its field coil(s). This current is small and controls the output. What the Adverk does is control the alternator output by controlling the field current. Other controllers have functions like limiting the time of maximum output and operating in float mode on long runs.

 

[lustyd]

Ah that makes some sense. So I probably want to reconfigure it to the engine battery and let it do it’s thing while the b2b takes some charge to the house bank

Are you going to tell us. Iithium nuts, what you went for lithium wise and why?

The alternator output is still carried by the original wiring.

If you are fitting lithium batteries as the domestic battery the Adverc sensing will have to be transferred to the engine start battery. The B2B charger will take over the charging of the domestic bank making the vsr redundant. As there is no real need to boost the charging of the starter battery the Adverc is unnecessary.

 

[Tintin]

The alternator will have been modified so that the Adverc controls the voltage.

If you remove the Adverc you'll need to reinstate that.

If you are getting rid of the adverc please drop me a message, I'd be interested in buying it.

It overrides the internal regulator in the alternator so that you get 3 stage charging and hence better battery performance. It has a sense wire to the battery and an extra control wire to the alternator field brush to achieve this. A good bit of kit, keep it as long as you are sure that your lithium batteries will be OK with it.

I got a Fogstar Drift 300Ah battery. I got it because it was reasonably priced, had all the features I need, is available in the UK easily with support and warranty, and because it had the right dimensions. It turned out they didn’t include the handles in the dimensions so doesn’t fit the battery box after all, but they agreed that cutting the handles off won’t void the battery warranty so all good.

 

[lustyd]

Thanks all really great info. I think for now I’ll just move the sense wire. I’ll look into removing in the future as I don’t think it’s needed with the other stuff.

 

[PCUK]

You will regret removing it as charging will be badly affected without it!

That is the battery I would have bought if I was going the drop in route. Good choice.
Did you buy one or two? I currently have 280Ah at 24v but will be adding a second battery in a couple of months. We average 230Ah of consumption per day at 12v

No. It will be unnecessary as its current purpose is to improve charging to his lead acid service bank which will not then exist. His new service bank is lithium and charging will be controlled by the B2B charger from the starter battery which will always be fully charged.

 

[Boater Sam]

But if you just remove the sense wire it will overcharge your battery! It will not sense the voltage! Disconnect the extra wire at the alternator, then the alternator will run on its own internal regulator.

Just the one due to space. We also probably don’t need more capacity as we’re not living on board yet. Coming from 2x120A AGMs it’s a huge step up

I can attach that wire to the start battery though?

Also just found a relay that seems to connect the two banks independently of the VSR which I assume is part of the Adverc?
