I've got a $1000 saltwater reef tank with corals.............yet procrastination doesnt' allow me to wire this up........
For fish tanks, I'll explain it but I'm too lazy to google it.
A 12VDC output trickle charger plugs into your wall, both charging a 12 volt deep cycle auto battery, and holding in a double pull double throw, or quad pull double throw relay/contactor. Through the relay (while engaged) contacts, (10-15-20 amp or more contact rating) sends 120VAC powers (sourced from the wall power) for a multi-outlet power strip (or strips) that powers your fish tank.
Oooops Oh No, the House power goes out and you're not home................ the AC trickle charger plugged into the wall goes off line, and so does the contactor coil and thus the contacts feeding the wall power to the power strips. BUT on that double throw relay contactor, in the non-engaged contacts position, is now engaged the output of a 120 VAC output Inverter ( say 1000-1200 watts) to power FishTank cirulation/air pumps, that is now powered off of the battery, giving you 120 VAC to the tank
so in a nut shell, an Fish Tank power source:
A or B circuit..... 120VAC power from the Wall, or the Inverter, that is auto switched by a relay/contactor that is held in or disenguaged from the Wall Wart trickle charger, that not only holds in the relay when Wall Power is present, but also charges the car battery while Wall Sourced 120VAC power is present.
But when house wall power isn't present, the contactor switches over to A/C inverter output to power to the fish tank.
Class, any questions?
Gads, I should of just googled it, but to a Sparky Wiring guy with a soldering iron, that "should" make sense.
it's somewhere on here.

Meanwhile when I'm away for weeks on a scuba vacation, a neighbor just comes over and turns on my 2000 watt Honda Generator ( that runs for like 8 hours on a gallon of gas at ubber quiet 58 dB) to power my 135 gallon reef tank.
