Lowest OCV An MPPT Is "Worth It"?
There has to be some experience here on this forum to share. When I look at the MPPT manufacturer's data specs, the incredo-hyperbole gives me diarrhea.

Hi Señor. This is for my secondary system. The 1st 150kWh down here costs the eqvt of 4.6 CENTS USA per kWh so I use it and the 2nd tier 6.7 cents kWh 50 kWh allowed for a total of 200kWh. After that, the electricity costs soar to unbelievable heights.
It's when we have zero power, or 22.8 VAC available that I have to rely on alternative energy. We have giant scorpions down here that love the get underfoot, hide in rolls of tissue, towels, shower curtains.
Bathroom is separate from house. Rigging up high power UV emitters that will illuminate 1 minute before the lights come on. Decided to go fluorescent tube rather than LED because of the short run time. Scorpions glow bright green under UV light.
But rather than operate a DC / DC buck off the 24 volt system, I went to a separate 12 volt system. The 24 is for the 4024 Trace and primarily for the 32 cubic feet of freezers, and a PSW small inverter for sensitive loads.
