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 creates 24 volts DC, which in turn would go to the inverter and is transformed into 240 volts AC, therefore it can power all the 240 volt material in the home.

Nevertheless, you can find areas of the old 12 volt system nevertheless being used, including most of the lights, a little pump and some other odds and ends.

as opposed to get and change every thing, i desired to help keep it operating as it had been, additionally one bank of batteries continues to be working and I also wish to ensure that is stays running provided that I’m able to.

The solution to my prayers had been a little DC to DC converter (ie 24 volt to 12 volt converter), which will allow us to perform the old material from the system that is new. We nevertheless wished to have the ability to run the stuff that is old the old lead acid battery bank if We had a need to. Getting the lights operating on the system that is old to be specially handy once I ended up being bedding the latest system straight straight down. Once in awhile i might get things incorrect, over extend the brand new system so that the inverter turn off and then we destroyed energy. If this occurred during the night, we might have forfeit the lights too but simply because they remained running from the old system, i really could at the very least see to work through exactly what I experienced done incorrect utilizing the new system.

I needed some way to switch between the two, and the easiest way was to install hookup mobile 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 that have a battery pack to perform devices in addition to a battery to start out the car. Battery pack isolator switch enables you to draw current from either or both batteries to ensure that if you need to, it is possible to separate the staring battery pack from the machine and steer clear of flattening it, therefore stranding yourself down in the bush someplace.

The image in my own head of the battery isolator switch had been a switch that is rotary would use 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 and also the negative and positive through the household circuit and I also could simply alter among them. It only had room for 3 wires – battery 1, battery 2 and the common wire when I got hold of the switch. As it happens so it just switches the positive cables and I also had to take action else using the negative cables of each and every circuit.

It dawned on me personally that the best way to run it absolutely was to collect all 3 negative cables and run them up to a basic link so that they had been connected.

You learn one thing brand new every single day and whenever we went along to my local electrician supply spot i came across which they made neutral links with varying opening size and I also surely could get one utilizing the size which will make the (quite dense) 12 volt cables effortlessly.

Therefore to create all of this up, I ran 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 a poor cable through the production regarding the converter into the link that is neutral. We took the negative cable which ran through the 12 volt batteries towards the negative supply point for the home circuits, cut it in two and went both ends to the basic link, therefore doing the negative region of the circuit.

To accomplish things we became popular the rear of battery pack isolator switch, exposing 3 terminals that are threaded with a nut and lock washer which accepted spade or ring terminals. We went a cable through the good terminal regarding the converter to your “1” terminal of this switch then broke the wire that is positive the 12 volt batteries to the good supply point for your house circuits, soldered on a few band terminals then linked battery pack part into the “2” terminal therefore the household supply region of the wire towards the “C” (or “common”) terminal.

This means if the switch had been looked to “1” the illumination ended up being running on the 12 volt system so when it absolutely was looked to “2” it had been running on the newest 24 volt system through the 24 volt to 12 volt converter. (clearly once the switch had been looked to “1 + 2” it might draw energy from both systems).

Now the acid test! Would everything work when switched towards the system that is new?

Fortunately it did, working well whenever switched to either the old 12v or even the new 24v to 12v part. Additionally, to date, operating the lights straight off the system generally seems to work very well and so they usually do not eat that much energy over and above that which we had been currently making use of. The machine is currently quite versatile, enabling me personally to run the lights on either the old or system that is new as required.
