The charger will still charge to full voltage even with long leads. As the battery charge level increases, the charge current drops and so does the volt drop. So it make take longer but will charge battery to full charger voltage.
Thanks for the comment. That’s actually not correct. The charger will think the battery is full before the battery is actually full and go to float sooner than it should. Leaving the battery less full than it should be. Having a charger many meters away from the battery is a poor design and all charger equipment manufacturers advise against long lengths of cable. Cheers.
Wouldn’t you just increase the cable size to minimise the volt drop though?
Thanks for the comment. These units have a very small terminal size built in and as such the unit can really only take a 6mm2 or 8b&s cable. They really are designed to be mounted as closely as possible to the battery.
Good stuff, new sub. Of course i have just purchased a van with a BMPRO Battery Plus-11-HA......
That’s ok. It may be fine for your needs. Otherwise as you can see from a number of our videos, it’s easy enough to upgrade.
@@outechoffgridit’s now on the list! Now to find a qualified installer as per your recommendations. We are in Wodonga, otherwise I would be giving you a call!
Thanks for the great videos.
In this example, how is the BMPro reading higher than the Simarine if its a voltage drop issue? I fully agree that voltage drop would be an issue when it's actually outputting charge to the batteries.
Just trying to get my head around that one!
Cheers.
Hi mate. Thanks for watching and commenting. In this example we had the 240v plugged into the van to show the BMPro charging the battery from mains. Hence why the higher voltage at the BMPro itself.
Surely the BM Pro must have a voltage sense input that can be wired to the battery? Surely?
It has an optional shunt with a voltage sense on it. The standard unit does not have a voltage sense.
Is the PM300 system a better option to go with? Or exact same issues? Which system is better to add extra solar to plus another MPPT to run it?
Thanks for your vids.
In our opinion, any all in one system that is limited to a maximum charge output of approx 30a is fine for simple and basic 12v loads such as lights, pumps usb etc. if you want to run a large inverter based offgrid system you are definitely better suited to larger output systems that have larger outputs in all in one systems or simply replace with individualised components to do the job. That was it’s a flexible system and can be designed to suit the users requirements.
