I just noticed that under the heading FAQ Batteries, the statement is made "You shouldn't charge LiFePO4 batteries below 0°F because it causes irreversible damage (video ref). " Shouldn't it read 32 degrees F? Thanks for reviewing this.

Question about a pool pump - JP21-19/900 - 72VDC, 900w, 1.2HP, 62ft, 92GPM, Solar MPPT Controller -
I have 4 x 270watt @ 35.5v Solar Panels.
Will the controller handle 142 volts coming in and deliver the required 92v and 900w if connected in series?
Or will I have to connect 3 panels in series and 1 panel in parallel to them?
Or possibly 2 pairs of panels in series and then connected in parallel?
Trying to get a handle on grounding array and system.
Watching video on 48V All In One system, but there is nothing in that video concerning grounding. Building ground mount rack for 4 350 W panels.
