Setting up the 24 volt to 12 volt Converter

The new grid that is off which we’ve in place creates 24 volts DC, which in turn would go to the inverter and it is transformed into 240 volts AC, therefore it can power most of the 240 volt material in the home.

Nonetheless, you will find areas of the old 12 volt system nevertheless being used, including all of the lights, a little pump and a few other equipment.

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

The response to my prayers ended up being a tiny DC to DC converter (ie 24 volt to 12 volt converter), which will allow us to run the old material regarding the brand new system. We nevertheless wished to manage to run the old material on the old lead acid battery pack bank if We had a need to. Getting the lights operating on the old system proved become specially handy once I had been bedding the brand new system 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 lost the lights aswell but since they remained running regarding the old system, i really could at the very least see to work through exactly what I experienced done wrong using 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 which may have a battery pack to operate 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 to make certain that if you need to, it is possible to separate the battery that is staring the machine and get away from 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 rotary switch that would simply 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 additionally the positive and negative through the household circuit and I also could simply alter among them. Whenever I got your hands on the switch it just had space for 3 wires – battery 1, battery 2 in addition to typical wire. 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 on me personally that the best way to run it absolutely was to assemble all 3 negative cables and run them to a basic website link so they really had been linked.

You learn one thing brand brand brand new every single day and whenever we went to my neighborhood electrician supply destination 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, we went cables through the negative and positive terminals of my 24 volt battery pack bank into the input part regarding the 24v to 12v converter. When I went a poor https://hookupwebsites.org/xpickup-review/ cable through the production regarding the converter to your link that is neutral. We took the wire that is negative went from the 12 volt batteries to your negative supply point for the home circuits, cut it by 50 percent and went both ends to the basic website link, hence doing the negative region of the circuit.

To perform things we shot to popularity the rear of battery pack isolator switch, exposing 3 threaded terminals fitted with a nut and lock washer which accepted spade or ring terminals. We went a cable through the good terminal associated with the converter to your “1” terminal for the switch then broke the good cable from the 12 volt batteries to your good supply point for the home circuits, soldered on a few ring terminals and then linked battery pack side to your “2” terminal plus the household supply region of the cable to your “C” (or “common”) terminal.

This means as soon as the switch had been looked to “1” the illumination ended up being running on the 12 volt system as soon as it had been turned to “2” it had been powered by the latest 24 volt system through the 24 volt to 12 volt converter. (demonstrably as soon as the switch had been turned 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?

Fortunately it did, working well whenever switched to either the old 12v or the brand brand new 24v to 12v part. Additionally, to date, operating the lights straight from the system generally seems to work very well as well as usually do not eat that much power over and above everything we had been currently utilizing. The device is currently quite versatile, permitting us to perform the lights on either the old or brand new system, as needed.
