I have this unit, no manual was bundled, recommended to watch this video clip:
The robot voice is terrible, but that’s out of the point. It features a model not exactly like mine and find no other YouTube clips or google information for my model. (I hope somebody who speaks proper English makes a detailed video for this particular model!)
At the end the mad voice goes through the settings in the app. He skips a few settings and doesn’t describe all I need.
Perhaps you guys can help
It is being mounted in a sailboat. I don’t want to have to give it start current every time the BMS cuts off.
The sailboat will be left unattended for long times so it must be fully automatic. Bilge pumps, alarm etc are dependant on electricity.
I was told by the solar MPPT regulator, Morningstar Corporation, I need to reprogram their TS-MPPT-30 to cut off earlier than the BMS cuts off charging as the MPPT can be damaged it battery power is cut off all off a sudden while charging.
I need to draw up to 200 A to a inverter sometimes. It is rated to 200 A draw so should be fine. When testing at home with a 2 kW fan via Inverter it cut off at 1350 W already, way to early. Probably because I haven’t set the BMS up properly. I am certain it was not the inverter which cut off, it is the BMS.
When that happens it turns off and gets grumpy, have to wake it up with 5 V power from a battery pack. Again, unacceptable on a sailboat.
I used to have AGM so some of this is new to me. What is SOC etc, how should I configure all values to make it work like the requirements I outlined above? Will I need to put a USB outlet next to the BMS and always feed it with 5 V to that port? If so, will it draw a lot of current that way all the time of just when waking up is needed? Should I connect that to my lead acid start battery? That is a separate battery bank, they share a common minus but separated on the plus side by a charging relay. What if they get connected? Big fire?
Seems like a bad solution to have 5V always on from a separate battery bank but if it is what it takes so...
The settings I need are:
Balance always gray, how to turn on.
SOC number
Board settings
Temperature difference set to 255, seems wrong?
Max voltage
Min voltage
charge connect/disconnect
MOS (what is it)
thanks!
