Hi, I have my solar setup complete. I have a 4s 3p solar array with 4 48v 150ah lithium ion batteries in parallel and the Growatt SPF 6000 DVM inverter. Everything is working great but I am not getting any current from the solar panels to charge the batteries. The voltage is dead on but I am only getting like 25 watts a no current. I know there current coming from the solar panels because I accidently got a nice jolt by touching the wires. Any thoughts would be greatly appreciated.
