Ordered a 500a BMS from Daly.
It arrived in 14 days as promised.
I connected battery “sampling” wires as directed but Bluetooth doesn’t work properly or stay connected.
I contact customer support and they tell me to mail it back so they can repair it.
They accuse me of shorting it and...
so here’s what I’m wondering
Why is my SCC shutting down after lunch?
Why is my SCC getting unbearably hot at 5pm pushing 14v/40a?
Does anyone know the thermal properties of these SCCs?
When SCC shows 600w from panels, that’s a fair amount of wattage to dissipate as heat energy.
Is there a...
An MT50 is a device to read/write parameters on the EPEver charge controllers.
I use around 300ah daily on an offgrid mobile setup, sometimes I don’t get much sun due to shade, rain, travel, or a combination of factors thus I would like to keep my cells charged to the top when light is...
The MT50 doesn’t allow for temperature input (especially on BN series which doesn’t support temp at all), which is a big reason I am switching to the AN.
Battery built of raw cells #8 3.2v LiFePO4 400ah cells wired 2P4S for 12v, 800ah with a 250a Daly Smart BMS.
Panels are #3 250w wired 3S for...
Not useless. But “before the sun goes down” means the SCC is still charging, means the voltage won’t be precise, but FWIW I can tell you my voltage won’t go above 13.3v from 13.15v on a single 12v/40a MPPT.
The only time my battery voltage goes above 13.4v is when both 40a MPPTs are charging...
Not to hijack this thread but I have a question about setting as well.
I’ve set my battery type to LiFePO4 numerous time via the Bluetooth app but it still says “User” on the basic settings screen.
The Advanced settings screen doesn’t seem to reflect LiFePO4 parameters, can someone tell me...
A single charge controller working between lunch>supper can’t really move my voltage: my bank is 12v 800ah and two 40a SCCs would have to work at near max capacity all evening to “fill” my cells. Voltage isn’t a great indicator of charge for LiFePO4 anyway, but I can tell you that the BN MPPT...
Here are my settings currently.
Note that I can’t get the battery type setting to change to LiFePO4. Not sure what I’ve done but the other parameters are not problematic to change.
They are at 13.2v nominal voltage bc my other EPEver BN series MPPT is still charging at >9a.
If I open breaker on BN MPPT voltage drops to 13.1v yet the AN MPPT still does nothing after lunch.
Float voltage is set to 13.4v and Boost reconnect is set to 13.2v.
As title says, I have a Tracer AN series connected to my batteries but after the MPPT reaches some voltage (boost I assume) the current to batteries drops to zero.
If I reset the Tracer 4215AN (open panel AND battery breakers to MPPT) it will begin a normal charge cycle again, boosting to 14v...
@Damon Ye this is what I am talking about.
Shorting the Daly works to start it, does it also void any warranty?
My 2cents for @tsenator would be to avoid doing this. I shorted my 500a Daly maybe 10x in a few months to start it, and eventually this cooked my Bluetooth port. Daly sales helped me...
My Daly had this setting and Bluetooth connection was never any problem, in fact best Bluetooth I’ve used better than Xantrex or Schneider!
About my 500a BMS:
I used a wire to jump the Daly because it would not turn on otherwise, if you look back you can see many posts about this issue and...
