Any way to switch power source at nighttime?

    Hi everyone. I'm running a giant quarry with a Fast Electric Engine hooked up to 1 Advanced Solar Panel. The engine sucks the panel dry so no energy can be stored for the quarry to operate during nighttime. Right now I have two aux redstone engines that slowly run the quarry when there's no power.
    So I crafted another solar panel and a mfe that stores energy during the day.
    Question: Is there any way to automatically switch between given power sources?

    For IC2 power, you can use power switch cables and a solar detector:


    Code
    SL
CI




S = single solar panel
C = detector cable
L = lever set to on
I = induction furnace or other advanced machine


    Ill go ahead and explain this,


    Induction furnace acts as a EU sink.
    Lever sets Induction furnace to "Always hot" mode causing it to build heat. (Consumes exactly 1EU/t)
    Single solar provides the required 1EU during the day but 0EU during the night.
    The detector cable is used to sense the change in EU flow.


    voilà! A perfect light detector.

    What if people don't have RedPower2?


    Da horror! Y wud you evar assume da ppl dun't play w da same mods az u?!?!22111?1?1!!!


    Joking aside, It's a clever setup, really... Course it would be better if the OP invested in other power alongside his solar setup... /shrug

    Every Mod Author, in existence. And yet, you STILL say otherwise.

    instead of a energy sink like an induction furnace, you could actually use the detector to power a splitter cable, while as energy sink you use a sufficient large storage blok (mfe/mfsu)


    That way the energy won by the solar panel(s) is not wasted but instead used to fill the night supply. once the sun goes down, the panels dont produce eu -< detector cable switches off, splitter cable enebles current, and your mfe/mfsu starts emitting power to the engines.

    Except if the MFSU fills up it totally breaks your system.
    When some friends were designing a city (this was before RP2 had the light detector) they had a few solar panel scattered about (because even RP2 wires have their limits) and a mass fab for each one.
    The mass fabs dumped their uu-matter into an ender chest where it got converted to snowballs with a BC autocrafting table and wasted with a dispenser.

    thats why I said a sufficient large storage block. an mfe is enough when using a few solar panels. then again, it wont last a full night.


    It's a bit mix and match in how many resources you are willing to spend versus the amount of nightwork required


    you might aswell replace that induction furnace with a mass fab in the original post. or even place it parallel with the mfe/mfsu. that way there will still flow current even with a full storage block.
