Review on 🌞 bayite BYT-7A006: Quiet DC 12V Solar Hot Water Heater Circulation Pump with 3M Discharge Head and 2.1GPM Flow Rate by Keith Maynard

Worked well for the first few hours but blew out after the fourth hour. The engine just hums. Wires are thin 20 gauge, should be 1 size larger. It drew 0.75A from my 12.5 volt battery, 0.9A from the 16.5 volt solar panel. I measured about 1 gpm at a head height of about 5 feet. A little less with a battery, a little more with a solar panel. There were no instructions so I was never told what not to do. I tested partial panel shading and had no problems. Maybe he won't survive the sunset. But I thought that was the point. This is a solar water heating pump, so pump when it's sunny, stop without sun. I've emailed the seller, let's see if he responds. Only worked 4 hours :-( I was only checking for that reason because if the pump ever fails your solar water heater will trip the P/T safety valve and water will flow all day. If the P/T safety valve fails, The Hose near the solar water heater may burst.
