i have 4 x 290 watt solar panels connected in parallel. All-in-one inverter by Growatt SPF 3000TL LVM 24v.

on the display panel i am getting solar input
27v
7amp
450watt

my clamp meter measure the solar input cable, about 18amp

is the amp display on the display panel of Growatt not as important as the wattage ?? Should i just pay attention to the wattage only ??

Or should i connect my panels differently ???

battery bank: 24v 200AH Battle Born Lithium. 4x12v 100AH battery. Connect in series, than parallel



thanks for any advise

frank

27 volts is not enough to charge those battleborns to 100% state of charge. Read my reply to your other thread.

Summary, connect those panels differently.
