Suddenly appear to have a controller problem. 2 x 160 panels in parallel. Output normally well in to 200w+ range, even over 300w on odd occasions. Smartsolar showing very low wattage much of the time despite clear (Algarve) sun. If I go into settings and switch off then back on, panels show 20.16v 245w output but, within a few minutes, status drops as low as 1w and at the moment is cycling between 39w and 70w @ 19.73 volts, 2.1A charge. No clouds, orientation to the sun unchanged. Any ideas?
P.S. Controller light says "Float" but according to App it's in "Bulk" mode
