Setting up the 24 volt to 12 volt Converter

The new off grid system which we’ve in position creates 24 volts DC, which in turn visits the inverter and it is changed into 240 volts AC, therefore it can power all the 240 volt material in the home.

Nevertheless, you can find components of the old 12 volt system nevertheless being used, including most of the lights, a tiny pump and some other equipment.

as opposed to get and replace every thing, i desired to keep it running as it absolutely was, additionally one bank of batteries continues to be working and I like to ensure that it stays running so long as I am able to.

The solution to my prayers ended up being a little DC to DC converter (ie 24 volt to 12 volt converter), which will allow us to perform the old material regarding the system that is new. We nevertheless wished to have the ability to run the stuff that is old the old lead acid battery pack bank if We had a need to. Getting the lights operating on the old system proved become especially handy once I had been bedding the brand new system straight down. Once in awhile I would personally get things incorrect, over extend the brand new system so that the inverter turn off and now we destroyed energy. If this occurred during the night, we might have lost the lights aswell but simply because they remained running regarding the old system, i really could at the very least see to sort out exactly what I’d done wrong with all the new 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 that have a battery pack to perform devices in addition to a battery pack to start out the car. Battery pack isolator switch lets you draw current from either or both batteries in order that if you need to, you can easily separate the staring battery pack from the machine and get away from flattening it, thus stranding yourself away in the bush someplace.

The image within my brain of a battery pack isolator switch ended up being 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 additionally the negative and positive through the household circuit and I also could simply alter among them. Once I got your hands on the switch it just had space for 3 cables – battery pack 1, battery pack 2 plus the common cable. As it happens it only switches the good cables and I also needed to take action else because of the negative cables of every circuit.

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 brand new each day and whenever we decided to go to my local electrician supply destination i came across I was able to get one with the size which would take the (quite thick) 12 volt wires easily that they made neutral links with varying hole size and.

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

To perform things I shot to popularity the rear of battery pack isolator switch, exposing 3 threaded terminals fitted having a nut and lock washer which accepted spade or band terminals. We went a cable through the good terminal of this converter to your “1” terminal of this switch after which broke the wire that is positive the 12 volt batteries towards the good supply point for the home circuits, soldered on a few ring terminals then linked battery pack part to your “2” terminal therefore the household supply side for the cable into the “C” (or “common”) terminal.

Which means as soon as the switch had been looked to “1” the illumination was 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. (obviously as soon as the switch had been looked to “1 + 2” it might draw power from both systems).

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

Fortunately it did, working well whenever switched to either the old 12v or perhaps the brand new 24v to 12v part. Additionally, to date, operating the lights straight from the system appears to work very well and additionally they try not to eat that much energy in addition to everything we had been currently making use of. The device happens to be quite versatile, allowing me personally to operate the lights on either the old or brand new system, as needed.
