[RE-wrenches] DC Solenoid Coil Current

[Larry Crutcher, Starlight Solar Power Systems]

...600 Watt HOURS per day….

It must be active 24/7. If deactivated, the battery is disconnected. Thanks but this is irrelevant now since I found a 500 amp solenoid that only consumes 41 WH per day.

OK So if you only have the 600 watts per day when you are either on shore power or on a genny can you design the system to not be needed when they are off and kill that load

Hi Jerry,

The no-fault condition from the CPU is +12Vdc. A fault causes 0 volts. These are the contactors I plan to use: http://www.alliedelec.com/search/productdetail.aspx?SKU=70062412

So Ian clear does the fault activate the relay or does the absence of the fault activate the relay because its usually best to have a absent or no fault hold the relay on and if anything fails as a the relay will rest this can be done with motorized on or contactor high load switch, you should also look at the switch AIC rating also
