I got the email from MPP with the DSP and MCU firmware updates. The older unit update went smoothly but the newer unit failed immediately. I soldered the 3m ohm dealio onto the data line in the cable still no luck. Shut the unit down and it would not come back on. Just 1 red flashing led...
Waiting to hear back from MPPSOLAR. They had me check to make sure both inverters were set to 120v in setting 10. Verify comms cables are connected and no current sharing cables are connected. Surprised they didn't ask me to check the firmware 1st.
Inverter 2 saved 2p2 180 change without an...
I just purchased another LV6548 for Split Phase operation. One unit is on Firmware 45. xx and the other is on Firmware 69.xx. This doesn't seem to be a concern with MPPSOLAR's support because the 1st thing they had me check was to make sure the comms cable was connected, and then no current...

I have 2 lv6548's running in splitphase. w/1 Jakiper 5kwh battery and 1 DIY 16s 15kwh lifepo4 battery. Can I hook each battery up to 1 inverter rather than having the 2 batteries connected to both inverters via a bus bar?

USB to RS232 Male Adapter with PL2303 Chipset connected to the cable that comes with the inverter. I located the correct win 10 driver and no errors in device manager. I...
well you are getting there....let me help you out some more. Sungoldpower makes sp6548 (recently had the mfg modify their model to handle pv input 399v (I think they couldn't go to 500v because of the exclusive deal with signature solar) signature solar makes 6.5kW Off-Grid - EG4 6500EX-48...
I understand that English may not be your 1st language and you seem to have gotten off track by jumping on a few trigger words which clearly have clouded your ability to understand what is happening here! So let me help you out with some hints. If you had to pick the clone, (not saying it is...
They are an established distributor for MPPSolar with over 6064 sold units with 100% Feedback. They were the ones that gave me the info on how to contact MPP solar. So what you are saying the clones are taking out other clones not MPP solar (mfg). Sungold power 6548 is running fine. I...
