24 volt battery pack hookup. Energy Our Off Grid Adventure Installing the 24 volt to 12 volt Converter

Setting up the 24 volt to 12 volt Converter

The new grid that is off which we now have in position generates 24 volts DC, which then would go to the inverter and it is changed into 240 volts AC, so that it can power all the 240 volt material in the home.

But, you can find components of the old 12 volt system nevertheless being used, including all of the lights, a tiny pump and some other odds and ends.

as opposed to get and change every thing, i needed to keep it running as it absolutely was, additionally one bank of batteries continues to be working and I also like to ensure that it stays running provided that I am able to.

The response to my prayers had been a little DC to DC converter (ie 24 volt to 12 volt converter), which will allow us to operate the old material in the system that is new. We still wished to manage to run the stuff that is old the old lead acid battery pack bank if We needed seriously to. Obtaining the lights running on the system that is old become specially handy once I ended up being bedding this new system straight straight down. Once in awhile I would personally get things incorrect, over extend the brand new system so that the inverter power down and now we destroyed energy. If this occurred during the night, we might have lost the lights also but I could at least see to work out what I had done wrong with the new system because they were still operating on the old system.

I needed some way to switch between the two, and the easiest way was to install a battery isolator switch if I wanted to keep operating both systems (12 volt DC for lights and 24 volt DC – 240 volts AC for everything else. They are utilized in 4WDs and RVs which may have a battery pack to operate devices in addition to a battery to start out the automobile. The battery pack isolator switch lets you draw current from either or both batteries to ensure that if you need to, it is possible to separate the battery that is staring the device and prevent flattening it, therefore stranding yourself call at the bush someplace.

The image in my own mind of the battery pack isolator switch had been a switch that is rotary would just take the negative and positive cables through the 24 volt system (through the converter to 12 volt), the negative and positive through the initial 12 volt system while the negative and positive through the household circuit and I also could simply alter among them. Whenever I got your hands on the switch it only had space for 3 cables – battery pack 1, battery 2 therefore the typical cable. As it happens I had to do something else with the negative wires of each circuit that it only switches the positive wires and.

It dawned so they were connected on me that the way to run it was to gather all 3 negative wires and run them to a neutral link.

You learn one thing brand new each and every day as soon as we went along to my neighborhood electrician supply spot i discovered which they made basic links with varying opening size and I also managed to get one with all the size which will use the (quite dense) 12 volt cables effortlessly.

Therefore to create all of this up, we went cables through the negative and positive terminals of my 24 volt battery pack bank to your input region of the 24v to 12v converter. Then I went an adverse cable through the production of this converter to your link that is neutral. We took the wire that is negative went through the 12 volt batteries towards the negative supply point for your house circuits, cut it by 50 percent and went both ends in to the basic website website link, therefore doing the negative part associated with circuit.

To accomplish things we became popular the rear of the battery pack isolator switch, exposing 3 threaded terminals fitted having a nut and lock washer which accepted spade or band terminals. We ran a cable through the good terminal associated with the converter towards the “1” terminal for the switch after which broke the good wire from the 12 volt batteries to your good supply point for the home circuits, soldered on a few https://hookupwebsites.org/matchbox-review/ band terminals then linked the battery pack part to your “2” terminal and also the home supply part of this cable into the “C” (or “common”) terminal.

Which means that as soon as the switch had been looked to “1” the illumination ended up being run on the 12 volt system as soon as it absolutely was turned to “2” it was running on this new 24 volt system through the 24 volt to 12 volt converter. (demonstrably once the switch had been looked to “1 + 2” it can draw energy from both systems).

Now the acid test! Would everything work when switched to your brand new system?

Fortunately it did, working well when switched to either the old 12v or even the brand new 24v to 12v part. Additionally, up to now, operating the lights directly from the system appears to work very well plus they try not to eat that much energy in addition to that which we had been currently making use of. The machine has become quite versatile, permitting us to operate the lights on either the old or brand new system, as needed.
