I don't understand why I received this protector when the listing clearly states that it is 110/220 V, but the one I received says 140-300 V.
T
Everything looks perfect from the outside. This is the only DC current limiter that we could find. We want to use it to limit the voltage from the panels 🌞 to the inverter in peak mode.
