Hey Guys!
I have some Second Life telecom Lithium Batteries "Powercube 1000 ESM-B02" from Huawei.
They run with 48V and have 100Ah. I want to connect those with our GroWatt Inverter, but haven't
success so far.
1. I tried to connect the batteries' BMS with the Inverter via a RJ45-cable, but they would not comunicate.
I don't know which of the more than 50 protocols to choose and even don't now if the GroWatt does support the
Huaweis Protocol. Does anybody now where to find a list of the supported protocols by Huawei?
2. My seccond attemp was to connect the batteries like "generic" ones without data cable comunication.
So I would start the batterie by connecting its PWR-Port directly to + and - pol of the battery by opening the batteries case.
The batterie would but and after aprox. 3 Minutes the batteries BMS would switch the internal relais to ON and I could use batteries for discharging and charging.
BUT after a couple of hours the relais would switch to OFF again. If I am restarting the batterie again the SOC is indicating 0% even so the volmeter shows fully charged batteries! The relais does not switch to ON again either. That already happend to 3 batteries and realy don't now what to do anymore.
Can anybody help me please?
