    Batrium balancing issue

    Well done for finding that, glad it is working for you now.

    Dual shunt on Batrium

    You need an outback Hub, and either an Outback axs port adapter or an Outback Mate3. You can then connect the outback mate or axs port via wired ethernet to your Internet router and have full monitoring and control from their opticsRe platform. It works very very well. I've just upgraded a...

    What's the absorption timer set to though?

    Batrium balancing issue

    You can always use a 12v car headlight bulb clipped across cell 7 to manually balance it, but to be honest it looks so close to the rest of the pack it looks more like cells 6 and 9 need a hard charge. You can start an absorption charge and then clip the bulb across the cell, watch what goes on...

    Batrium balancing issue

    This ^^^ You might need close to an hour or perhaps 2 hours of absorption timer to get this pack balanced, possibly even more. To do that you will need to cool the WM5. And you will need to limit the current from the charger, luckily the WM5 can ask the Victron charger to go into limit mode...

    Batrium balancing issue

    So, to understand your problem fully - you charge the pack and it balances when charging? You can bring all cells to 4.15v ok? As soon as you start to discharge the pack, cell 7 doesn't sag much and all the other cells drop from 4.15v very fast?

    Dual shunt on Batrium

    Yep, as has been said - the shunts go in series. I have an Outback FlexNet that monitors 1 shunt (it can monitor up to three) and right at the batteries I have the batrium shunt. Keeping the two in sync is a bit of a pain, they tend to drift a little over time and the genset %SOC start/stop is...

    Batrium balancing issue

    I don't see the problem here? It looks like your pack is pretty seriously mismatched and cell 7 is hitting it's upper voltage ceiling long before the rest of your cells are. You have a couple of options: Manually balance the pack then let the WM5 take over Put a cooling fan on the WM5 and then...

    Solar friendly Heat Pump for UK weather?

    Unless you want to retrofit UFH to all ground floors and take advantage of the reduced loop temperatures that brings, in turn enabling you to achieve a high COP from a heatpump, you're better going thermal store in my opinion. I'm a big thermal store fan, but then I have a unhealthy obsession...

    Batrium cumulus configuration howto

    I've asked for an update on the planned rollout of Cumulus. I have just upgraded my Outback system to a new Mate3S which supports their Cloud based control and visualisation system. I don't know how I managed without it and would really like the same ability from the BMS.

    Batrium cumulus configuration howto

    There is a link to the web portal on their new website, you can create an account and add devices... I've registered an account, I'll see if I can add my device.

    Batrium cumulus configuration howto

    Does anyone know if there is a howto out there for configuring the batrium cumulus web front end? Adding devices, configurations required on the toolkit end etc... Thingspeak is nice, but cumulus looks nicer. It would be great if it didn't need a host machine running the toolkit software too.

    REPACK MAKITA 3.0aH WITH MORE CAPACITY

    I would expect the original Makita cells to be more like 20a discharge rated cells, you might be out of luck putting in some low current cells like you have there...

    %SOC on/off under batrium

    I only picked that 'when all cells are in bypass = 100%' as what I would want batrium to use to recalculate 'full'. If you don't ever charge to those levels then you'd never hit 100%, which doesn't matter. You can tell it you are at 100% at any time, it's in the metrics tab iirc. A better way...

    %SOC on/off under batrium

    100% SOC is when all cells are in final bypass and your tail current drops below a certain value that you'll have to figure out. Cycle charge efficiency (that's what outback call it anyway) tells the shunt to discount a certain % of power that goes to charge the batteries, because of charging...

    %SOC on/off under batrium

    Give us an output that is on at X% and off at Y%, with X and Y programmable, that will do us. We'll work around that with our genset start controls.

    Can the MPP LV5048 clean up Line/Generator power?

    What makes you think your non inverter generator will put out dirty power? Is it really such a cheap pile of junk?

    %SOC on/off under batrium

    I mean it's hardly a complicated logic function to add... Hopefully they will add it in a future release

    %SOC on/off under batrium

    I use LiFePo4, I prefer %SOC vs cell/pack voltage because of my discharge curve
