Off Grid Living - Using Nickel Iron Battery technology

[Admin]

This thread is for those wanting to live in the country areas away from cities, and learn how to live off grid, making your own power.

We have specifically embraced the Nickel Iron technology and have set up webpage explaining how this is done.
If you are interested in Ni-Fe battery technology and want to learn how to do it, write your questions here.

What a fully completed off grid system looks like:



The link will give you set by set in setting up a Ni-Fe battery off grid system like this.

The overall cost is less than $18,000.

Batteries cost $9,000 and last forever

Inverters cost $2500 and last 5 years.

Solar controllers $1000 and last 10 years.

Solar panels $3000 and last 30 years.

Miscellaneous electrical stuff $2500



This system example uses 500 amp hour battery storage, designed for medium power users, who are used to consuming around 5 units of power daily. Off grid living is learning to do things based on sunshine and the time of day. My system is simple to set up and cheap to install. The Inverters run a single powerpoint with a maximum limit of 4 amps. This is around 930 watts, far less than your usual 2400 watts of a power point.
Your learn to look for appliances under 700 watts.

Thus no electric jug, no toaster and no vacuum cleaner. However you can find appliance solutions to such things as a 500W toaster? Does such a thing exist. You can even buy 24DC air conditioners.

Our biggest power appliances is the water bore pump and the water pressure pump. The rest of the 240V household appliances are chicken feed by comparison.

Going to purchase a battery hydrometer to test the gravity of the solution. I suspect the battery chemistry is spoiled by over charging?

This restoration process is not something you can achieve with Lead/Acid/

Another reason why I purchased Ni-Fe batteries. Hopefully I can get them to brand new again.

In the process of purchasing Jinko Solar panels, these come in at 34V and 10 Amp, just what is needed for a manually charging of the batteries if they become sluggish and do not reach their proper capacity.

I have not heard of anybody attempting a manual charge quite like this, so I will let you know how it goes.

The idea if to switch off Mppt solar regulators and associated solar panels. Switch off all battery loading.

Switch on the manual charging system, which will be 8 Jinko solar panels all wired in parallel to supply 80 amps at 34V for between 6 to 8 hours. This will overcharge the 500Amphr bank and hopefully restore the capacity of the batteries.

The manual charging system has no solar controllers. The amps comes in at the fullest rate with the voltage at 34V straight from the solar panels.

A benefit for having this system is to further increase the power to the inverters when used. I used to run 1500W water distiller, for only 30 minutes as the current solar panels cannot supply enough amps, especially on cloudy unpredictable days. Switching on the manual system along with the MPPT controllers should give my inverter the 50AMps it requires to distill water.
