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 it is transformed into 240 volts AC, so that it can power every one of the 240 volt material inside your home.
Nevertheless, you can find components of the old 12 volt system nevertheless being used, including all 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 it it is running so long as I am able to.
The solution to my prayers ended up being a tiny DC to DC converter (ie 24 volt to 12 volt converter), which may allow us to perform the old material from the brand new system. I nevertheless desired to manage to run the stuff that is old the old lead acid battery pack bank if We needed seriously to. Obtaining the lights operating on the system that is old to be specially handy once I had been bedding the brand new system straight straight down. From time to time i might 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 forfeit the lights aswell 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.
If i desired to help keep running both systems (12 volt DC for lights and 24 volt DC вЂ“ 240 volts AC for anything else) We required a way to modify involving the two, as well as the easiest method would be to use a battery pack isolator switch. They are found in 4WDs and RVs that have a battery pack to perform devices in addition to a battery pack to start out the car. The battery pack isolator switch enables you to draw current from either or both batteries to ensure if you need to, it is possible to separate the battery that is staring the machine and give a wide berth to flattening it, thus stranding yourself away in the bush somewhere.
The image in my own head of a battery pack isolator switch had been a switch that is rotary would use the negative and positive wires through the 24 volt system (through the converter to 12 volt), the negative and positive through the initial 12 volt system therefore the negative and positive through the home circuit and I also could simply alter among them. Whenever I got your hands on the switch it just had room for 3 cables вЂ“ battery 1, battery pack 2 while the typical cable. It turns out so it just switches the good cables and I also had to take action else using 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 new every single day as soon as we went along to my regional electrician supply place i came across I was able to get one with the size which would take the (quite thick) 12 https://www.hookupwebsites.org/malaysiancupid-review volt wires easily that they made neutral links with varying hole size and.
Therefore to create all this work up, we ran cables through the negative and positive terminals of my 24 volt battery pack bank towards the input region of the 24v to 12v converter. When I went an adverse cable through the production for the converter into the basic website link. We took the wire that is negative ran through the 12 volt batteries towards the negative supply point for the home circuits, cut it in two and went both ends in to the basic website website link, hence completing the negative region of the circuit.
To accomplish 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 band terminals. We ran a cable through the good terminal associated with the converter into the вЂњ1вЂќ terminal regarding the switch after which broke the wire that is positive the 12 volt batteries to your good supply point for your house circuits, soldered on a few band terminals then linked battery pack side into the вЂњ2вЂќ terminal and also the household supply side for the cable into the вЂњCвЂќ (or вЂњcommonвЂќ) terminal.
Which means that as soon as the switch had been looked to вЂњ1вЂќ the illumination ended up being run on the 12 volt system as soon as it had been looked to вЂњ2вЂќ it had been running on the brand new 24 volt system through the 24 volt to 12 volt converter. (clearly once the switch had been looked to вЂњ1 + 2вЂќ it can draw energy from both systems).
Now the acid test! Would everything work when switched into the system that is new?
Fortunately it did, working well whenever switched to either the old 12v or perhaps the brand brand new 24v to 12v part. Additionally, up to now, operating the lights straight from the system appears to work nicely and additionally they usually do not eat that much energy in addition to that which we had been currently making use of. The device is currently quite versatile, permitting us to operate the lights on either the old or brand new system, as required.
