Hello,
I just installed a 1,000 watt array with 2 series strings of 500 W each paralleled together. The panels are brand new (just released 100 W mono from Grape Solar). I have attached this array to a brand new Growatt 3000TL SPF LVM. The array voltage looks normal. However, the Growatt is showing only between 15 to 35 W being generated by the array. It is also showing 0 Amps for the entire panel array.
It is about 10 AM and there is still a lot of shade from the trees but why on earth would it say 0 Amps while the battery charger indicator LED is clearly blinking? And is it reasonable to expect such a low wattage for this 1,000 W array? I have another 2 strings left to add.
I did confirm that each string independently is showing a correct voltage reading in the Growatt panel. I also left a small fan constantly running as a load to test out the system.
This is my first system. Any help would be greatly appreciated.
