Many don't know but on the market there's 90% of LED lights for the house that actually have a forward voltage between 35 and 45 volts. I bought some dimmable led lights everywhere on Aliexpress and tested this myself. So perfectly suitable to drive with 48v.The driver is to lower the voltage...

I see though many houses going to evolve through a standard of 48v.

The Electrodacus looks a nice system but has only Max. 8 cells in series. With the ENNOID BMS you can put theoretically as many in series as you want. ENNOID has the choice in 2 different MASTERS. One can go as from 30v high as 150v 500 amps continous! This is the Low Voltage model!!! The high...

Forget it, it is not because it has a CAN-Bus it has support for the Victron and especially Daly's technic manuals are extremely poor translations. I gave up on them. Want to buy my Brand-new 20s 400A from me for half price. That one is never used. New in the box. My other 2 I blew up. Hate...

Like I said I've found a very interesting information and a specialized chip the LTC68xx series. Each chip can handle max 12, 15 or 18 channels or battery-cells with a accuracy of 1.5mV. And it has a isoSPI bus to connect multiple chips in series, completely galvanic isolated at 1mbps over max...

Hi Steve, I did some research in the mean time and read many reports from real specialists like engineers from BMW, cheap active BMSes are no good option either. It's better to have a good passive BMS than a the cheap Chinese based on capacitors only. I forgot what it was but these are not good...

Hi to you all, I'm decided, I'll trow all my Daly BMS-es in the garbage bin. ? I started to hate them after I broke 2 of them because I disconnected them in the wrong way to test and swap to the other again, I should have known better to disconnect the “-“ to the battery as last, but I was...

I just blew up 2 new Daly controllers by disconnecting in the wrong order. I followed the instructions in connecting in the right order but I didn't pay attention to unplug the other way around. I just wrote Daly an e-mail what they can do about. I'm really pissed of. I hope they can give me...

Seems like a good idea but what about the balancing, if the charger stops charging below the threshold of the passive balancing than no balancing at all happens, right?

I read about MPPT controllers blowing up because of disconnection of the batteries. But what I didn't know was that the output voltage of the MPPT rises before it blows up. That would go faster when the power of the Solar panels is on the limit that the MPTT can handle I think.

But I am not 100% sure about the stability of the Arduino. That depends more on the libraries I will be using I think and of course I can make a mistake myself. I'm thinking about using even a secondary Arduino or something else that functions as a watchdog for every few seconds. If the watchdog...

Thanks Craig!!! That's actually the answer I was hoping for. So, the overvoltage message will come from the Daly? I was thinking from the MPPT? And I wonder how many milliseconds are needed to react? Anybody an idea how fast that overvoltage builds up?

But wait, than I have a problem when the MPPT is disconnected from the batteries. How to take care of that? That is why I've put the MPPT controller directly on the batteries. I don't plan to buy a new Daly with separate port on 400 amps. What I'm going to do with this one?
