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 inside your home.

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

as opposed to get and change every thing, i needed to help 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’m 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 me personally to run the old material regarding the system that is new. I nevertheless wished to have the ability to run the old stuff on the old lead acid battery bank if We necessary to. Getting the lights operating on the system that is old become especially handy when I ended up being bedding the brand new system straight straight down. From time to time i might get things wrong, over extend the brand new system so that the inverter turn off and now we destroyed power. If this occurred during the night, we might have forfeit the lights also but since they remained operating in the old system, i possibly could at the very least see to work through exactly what I had done incorrect using the brand new system.

If i needed to help keep running both systems (12 volt DC for lights and 24 volt DC – 240 volts AC for the rest) We required a way to change involving the two, and also the simplest way would be to put in a battery pack isolator switch. They are found in 4WDs and RVs which may have a battery pack to perform devices along with a battery pack to start out the car. The battery pack isolator switch lets you draw current from either or both batteries in order for if you need to, it is possible to separate the staring battery pack from the device and prevent flattening it, thus stranding yourself down in the bush somewhere.

The image in my own head of a battery isolator switch had been a switch that is rotary would simply take the positive and negative cables through the 24 volt system (through the converter to 12 volt), the positive and negative through the initial 12 volt system as well as 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 needed to make a move else using the negative cables of each and 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 and every day so when we went along to my neighborhood electrician supply spot i discovered 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 wires through the negative and positive terminals of my 24 volt battery pack bank towards the input side for the 24v to 12v converter. When I went a bad cable from the production of this converter towards hookupwebsites.org/green-singles-review the link that is neutral. We took the wire that is negative went through the 12 volt batteries to your negative supply point for the home circuits, cut it in two and went both ends to the basic website website website link, hence finishing the negative part regarding the circuit.

To accomplish things I became popular the rear of battery pack isolator switch, revealing 3 terminals that are threaded by having a nut and lock washer which accepted spade or band terminals. I went a cable through the good terminal regarding the converter towards the “1” terminal regarding the switch after which broke the positive cable from the 12 volt batteries towards the good supply point for the home circuits, soldered on a few band terminals then connected the battery part to the “2” terminal as well as the household supply region of the cable towards the “C” (or “common”) terminal.

This means if the switch had been looked to “1” the lighting ended up being running on the 12 volt system as soon as it had been looked to “2” it had been run on the latest 24 volt system through the 24 volt to 12 volt converter. (clearly as soon as the switch was looked to “1 + 2” it might draw energy from both systems).

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

Thankfully it did, working well whenever switched to either the old 12v or the brand brand new 24v to 12v part. Additionally, up to now, operating the lights directly from the system appears to work very well plus they usually do not eat that much energy in addition to everything we had been currently making use of. The device is currently quite versatile, enabling me personally to perform the lights on either the old or system that is new as needed.
