Hi Danial you may find that the way you wired the panel might be the problem. The regulator should be wired as close as practical to the battery as the MPPT section of the regulator will take care of the resistance of the wire to the solar panel. If the resistance between the battery and the regulator is too high then the voltage drop between the regulator and the battery will be too high and the regulator will think the battery is fully charged and wind back the power. I have 3 of Voltx panels and they all come up to specifications. You can always do a rough test of the panels to see if they are working correctly. Measure the open circuit voltage (cold) should be above 20Volts that will tell you that each cell is working and none are shorting. Next short circuit the solar panel and measure the currant with a DC clamp meter with the panel in full sun light, it should be above 9 amps this also shows you haven’t any weak cells
Hi Daniel, do you find the Alvolta 200W solar panels to be good? I'm thinking of buying them for my 150Ah lithium setup (paired with my Redarc BCDCN1240). Thanks!
Hey Haiden They are alright, I wouldn't complain about their performance. I have two 200w foldable panels. The Alvolta, and a Renogy. The Renogy is very similar in weight and size, and it works slightly better than the alvolta. It is next to the Alvolta in the video. If I had to buy another panel I would go Renogy.

The Alvolta does 150w to 165w on sunny days, the Renogy sits some 5 to 10w above the Alvolta most of the time.
