Since the solar panel''s maximum Voc (50.882) could be slightly higher, how can I reduce it to be below 48V? Would any of below solutions work and practical, or are there better alternatives?

Before we delve into the solutions, let''s find out why your solar panel voltage is low. To solve the solar panel low voltage problem, it''s important to grasp the reasons behind it.
Customer Service
In the overwhelming majority of cases, the real reason is far simpler and much less intuitive: the solar array does not supply sufficient voltage for the MPPT charge controller to operate correctly.
Customer Service
The solar panel voltage must exceed the battery voltage by at least 5 volts for it to start charging. If the battery is already at 52 volts, you need at least 57 volts on the panels.
Customer Service
If voltage is much lower: The panel may be defective, shaded, or wired incorrectly. If voltage is zero: Check for broken wiring, loose terminals, or internal damage.

Solar cells actually produce lower voltage when they get hot. On a 40°C summer day, your voltage may drop 10–15% below the rated value. If your battery or inverter draws more power than the panel

Is your solar array losing voltage while under load? If so, the cause may be natural degradation or one of a few easy-to-fix issues. However, the problem can also be something more ominous. In this blog, we

Using a higher voltage panel, or lower voltage battery are your only choices. Remember that your mpp will be around 75-80% of Voc. You could find a smaller panel with the same Icc (I closed circuit) to put
