Review on ⚡ Enhanced Surge Protection Device by MidNite Solar - MNSPD-115 by Richard Ahmar

I connected this piece of junk to the output of my 280 watt PV panel. The panel was rated at 7.7 amps and 36.4 volts. The day was beautiful, clear and bright. All wires were hooked, as Mfgr. suggested. with the arrester connected I got 0.02 amps at 46 volts. My batteries were only charged to 11.8 volts when I started monitoring them. I pulled out the arrester and the current went up to 7.7 amps and the voltage dropped to 36 volts. .The power of my Tristar TS-60 controller went from 0.92W to 280W when the spark gap was removed. Midnight Solar reported that the arrester must have been damaged in transit. so that the shipping cost of returning the failed device to Midnight Solar will be incurred. the same back.
