Excess power?

[Bucho]

I design them professionally around 200 or so cell sites and a dozen or so weather and telemetry stations. I would never go off grid. I do have my ham shack that can run off-grid, but never ever been used except one night.

Thank you for answering my question.

I don't care. Just don't call me late for dinner.

OK you are like me then, a Red Neck joke.

PC is a weird Censorship huh? Anyone can call a white a Cracker, but use the N word and you loose everything unless you are Black.

Heck. Call me anything you want. I don't care. Just don't call me late for dinner.

Just stay out of the sun and wear a hat. That RED NECK will go away.

Now I can't do that to stop from being called a Fl Cracker.

For the record I had nothing to do with it because I do not whine or take offense when some disagrees or is wrong. Call me any name you want. I am proud to wear the badges especially the label of RED NECK.

We have been through this with dkpro1 before - he has a week to think about it.

unplug man and then shoot your numbers cell sites are far from living off grid

So what I see is a disagreement with someone that is living off grid and someone who understands the science behind battery charging.

dkpro1.

You believe that you are not really losing any energy because you have found a way to diverted excess power from the sun that is no longer needed to charge your battery system and instead is used to heat water or power some other load.

While you might feel that you are not wasting any energy you really are. It comes down to physics, science and math with respect to collecting, converting and using energy. There are built in "losses" that you can never recoup. You might be able to minimize those losses but never get rid of them completely.

Being able to happily live an off grid lifestyle has nothing to do with the math behind using the sun to charge batteries and run your appliances. Sure it can be done and a lot of people are living that way. Only most probably understand that there are "losses" in their system that can never be gotten back.

Talk is cheap King experience is not and you have none living off grid face it and eat it hot shot

That's a great response and all but it doesn't actually address what your experience with off grid solar is, have you ever been off grid?

Well my respomse was on here, it got deleted so let's try again.

dkpro simply does not know what he is talking about plain and simple.

Excess Power

Hello, please excuse me if my question is daft, but I would very much appreciate an answer. Having connected my batteries to the charge controller and inverter, how do I utilize the excess power produced by the panels (power not used for charging) there is a DC output on the controller for the excess power but if I connect that to the inverter as well as the batteries obviously I have a problem. Is it the case that I need to add a blocking diode of suitable size between the batteries and inverter, I have a battery monitor that places a shunt on the battery-inverter line, will this do the same job or am I barking at the wrong tree altogether? Thank you kindly for reading.

What make and model charge controller do you have Milo ?

most info is right here king but if you build a circuit that dump's extra power from array into a hot water heater when absorb is reached is it still lost king or are you lost?

I am not lost, you just do not know what you are talking about. Even beginners realize that in this thread. Read all the response, they get it and you don't. You lost the debate now get lost.

Several important points here:
1. As soon as you get to absorb? Then you run the risk of cutting back on the available absorb current, or else you are not using up all of the excess power.
2. With a more or less fixed array voltage (in the general area of Vmp) you have no way to modulate the power going into the fixed resistance heating element. Result is you either lose potential to charge the batteries or you do not use ALL of the potentially available panel power. Note my mention of the "inverse MPPT" output circuit.
3. Nobody (as far as I can see) ever said that you could not reduce the "waste" of potential panel power, just that it would never get as good as you can do with grid tie.
