Re: The best voltage to regulate AGMs to?

Discussion Board - 30 min 6 sec ago
I think your 14v is a reasonable compromise with the occasional boost to 14.5 as long as you make the correction for temperature. Unless you hear them venting they should not dry out but long periods above 14.5 probably should be avoided. AGM need high...

Tooltime66 : what you have essentially is a standard electrical system with a substituted electrical supply not all that different from taking a  house when the grid power is down and using a generator to power it

 If you had stack-able inverters that...

Depending on your area they are starting to want to know if there is a fire if you are off grid. Fire Departments want the disconnect to be visible and marked  for their safety. With two inverters you may have to have a single disconnect disconnecting ...

It seems I may have been thinking along the right lines, at least. The voltage I have been currently running is a compromise between the standby & the cycle voltages, which is 14.0 volts. But the system doesn't hold it there all day, once the bulk char...

Looks like I won't be needing my wind turbine.  I have it for sale if there is anyone looking.  What I understand is that this is a grid tie turbine.  You can refer back to my post in the wind section of this site and you can see what I found out.  PM ...

Ok, That is the info I was needing.  That being said.  I need to make decide what to do or not to do.   The tower is going up no matter what.  For a wfi repeater and ham radio.  Sure would like to put some sort of wind turbine on top.  I know that pv m...

Actually , those 6V folding panels are very useful to me.
I use one most everyday to recharge my cell phones. The output is perfect for a USB to micro-usb cable to charge put my personal and work phones.
Once they are charged, I then plug in a freebie-...

Not had dealings with one but I think Harold is right. It is an induction generator and gets its excitation from the mains supply and relies on the mains being stiff to hold frequency and volts.

It generates above synchronous speed, but the speed incre...

 From what I remember, the Enertech machine was an AC motor, that is under braking, until the wind reaches a preset MPH. Then, the brake releases, the motor runs up to speed, then gets driven "over speed", to produce current.

 I believe that "1800" c...

A lot of this is going to be dictated by the area you are planning to build.
  But you mentioned electrical a little out of the norm You should at least  follow the minimum NEC standards for all wiring.

Has anyone built a off the grid home and delt with the home inspectors with things like not installing a furnace, water system that will include a 500 gal water tank in the basement.  A electric system that is slightly out of the norm?

I believe it is more reasonable to regulate float current, not float volts.

Someone here told me it is reasonable for the battery to absorb .01C charge rate (100 hour charge current) without losing any water.. I would run it lower than that, at a C/200...

The brushless generators will not be a candidate for what I described.

So yes 60vac makes 84 volts. -2 volts for the diodes.

To be honest I'm not sure what is going to happen if you run a regular brushed generator at significantly lower rpms. the maxim...

sealed batteries are a bit of a compromise on a solar system - if you use the cyclic voltage then you're going to dry them out fairly quickly (assuming you're not cycling them down to 80% dod every day - in which case using the cyclic voltage would be ...
