Review on 💡 TWTADE SSR 40A 3-32V DC to 24-380V AC Solid State Relay by Norman Costello

We have created an additional safety shutdown for a mobile solar power plant. Our control circuit measures the voltage of the battery and when one of them exceeds the set tolerance it turns off a small relay which then turns off the power supply to that device. This unit then precisely cuts off the input from the solar array, effectively preventing overcharging and improving the overall safety of the system. The device has been in continuous use for several months and works reliably. Our load is much less than rated (about 10 amps at 30 volts), but the unit doesn't seem to heat up even when running.
