Two days ago, (after about almost two weeks since installation), my Growatt SPF 5000TL HVM-WPV started showing warning indicator code 19. From the manual, it says "battery disconnect".
The battery is a Rosen...48v, 4.8KW. Its voltage is now completely low and the inverter doesn't charge it. Was charging previously though. Note that I don't have solar panels connected to the inverter yet. It's currently connected to grid power AC. Power from Grid comes in as AC input. The picture below shows when I first got it installed and was working. You can see the green State of Charge light on the battery. Now, the battery doesn't turn on at all. And like I said, the voltage is completely low.
Also, the battery terminals on the Growatt inverter show very low volt measurement (.009)just like the battery. My guess is the invert isn't charging the battery. What doesn't make sense is how the battery drained suddenly.
