I have just ordered a 12V DC 250VA Phoenix Sine Wave Inverter and cannot find any reference to whether it will be damaged, a fuse blows, or whatever, if the 12 Volt input wires are reversed.
I can add a Mosfet protection unit on the input lead if necessary. The inverter will be used for temporary use and is therefore at risk of the supply being accidentally reversed.
Thanks
There is no reverse polarity protection on the DC battery connections.
Connecting the inverter in reverse polarity will destroy it.
Wow, that's not good. I will need to add one of my Mosfet protection modules into the cable. You guys might want to consider using such simple protection, check Analog Devices LTC4368 data sheet. I use their IC and two Mosfets in my protection boards. The circuit is in the data sheet and can carry in excess of 50 Amps.
