So my inverter is connected to the BMS and I can't modify the settings with the LI option that I have chosen. If I set it to USE defined option do I have to unplug the communication to the BMS? US2 it says suitable for lithium batteries when not using BMS cables

sorry about that... I'm charging with my growatt 6k inverter. only get about 50% with solar right now as I have 2 strings that are not connected. I usually top it off with my generator when cloudy. I noticed the last couple weeks that cell 8 is lower voltage than the others.

Hi, I have a 48 volt 200 ah battery that won't charge to 100 soc. It stops charging at 30 AMPS...and charges at 4amps until volt drops below 51 volts...then starts charging at 30 amps again. I checked the cells and they look out of balance. Does this mean I have a bad cell? I sent my issue to...

Oh they will replace the BMS.... for free plus 275 can for shipping.... what a ripoff...I paid 450 us to ship the battery and inverter..... something fishy...but they got me by the short hairs.

I'm wondering if I could find a BMS locally for the Rosen Battery? Any ideas?

So update from Rosen... I took the battery cover off... was no power on battery leads to inverter... but 48 volts on battery leads before bms...

The generator is a Costco brand inverter generator 8000 watts, It charges through the inverter at 30 amps. Funny you say the inverter needs more battery.... I bought them both from Rosen with the BMS exactly for the inverter. They never said anything about not being enough battery. I have close...

Hi Folks, I have a major issue with my system and I'm hoping its just me...lol ... I have been running this system for almost a year with no major issues. I have a growatt 6000 split phase with a rosen 10kw lithium battery. Last night I decided to top off the battery a little with my...

ya I'm in Canada... nice gene though!

5399 for a honda 7000 watt inverter generator.

Has anyone have a regular generator that works with Growatt inverters? I was able to test the inverter to grid power and it charged the battery. I want to make sure its not my generator before spending 5000 on an inverter generator. Thanks Rick.

Yes the setting for charging are set to utility first, then solar CUE 14.

Hi Folks, Newbie here!! I have been off grid for a few months now, and just got my solar gear installed. Of course the first week that it's setup is cloudy. I purchased the inverter with the intent that I could charge the battery with my generator when needed. Well it shows that I have ac in...
