Setting up the 24 volt to 12 volt Converter

The new off grid system which we’ve in place generates 24 volts DC, which in turn would go to the inverter and it is changed into 240 volts AC, therefore it can power all the 240 volt material inside your home. Nonetheless, you will find areas of the old 12 volt system nevertheless being used, including all of the lights, a tiny pump and some other odds and ends. As opposed to get and change every thing, i desired to help keep it running as it absolutely was, additionally one bank of batteries continues to be working and I also would you like 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 may allow us to run the old material from the brand new system. We nevertheless wished to have the ability to run the old material on the old lead acid battery pack bank if We necessary to. Getting the lights operating on the old system proved become especially handy whenever I had been bedding the brand new system straight down. From time to time i might get things incorrect, over extend the brand new system so the inverter power down and we also destroyed energy. If this occurred during the night, we’d have lost the lights also 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 needed to keep running both operational systems(12 volt DC for lights and 24 volt DC – 240 volts AC for anything else)

we required a way to change between your two, additionally the simplest way would be to put in a battery pack isolator switch. They are utilized in 4WDs and RVs which may have a battery to operate devices also a battery pack to start out the car. The battery pack isolator switch lets you draw current from either or both batteries in order that if you need to, you are able to separate the staring battery pack from the machine and give a wide berth to flattening it, therefore stranding yourself call at the bush someplace.

The image in my own brain of the battery pack isolator switch ended up being a rotary switch that would make 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 from the home 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 good cables and I also needed to make a move else aided by 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 new each and every day as soon as we went along to my regional electrician supply destination i came across which they made basic links with varying opening size and I also surely could get one using the size which may use the (quite dense) 12 volt wires easily.

Therefore to create all this up, we went cables through the negative and positive terminals of my 24 volt battery pack bank into the input part associated with 24v to 12v converter. When I went a bad cable through the production for the converter towards 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 in to the basic website website link, hence finishing the negative part associated with circuit.

To perform things we shot to popularity the rear of battery pack isolator switch, revealing 3 terminals that are threaded with a nut and lock washer which accepted spade or ring terminals. We went a wire through the good terminal for the converter into the “1” terminal regarding the switch after which broke the good cable from the 12 volt batteries towards the good supply point for your house circuits, soldered on a few band terminals then linked the battery pack part into the “2” terminal while the home supply region of the cable to your “C” (or “common”) terminal.

Which means if the switch had been looked to “1” the illumination had been running on the 12 volt system as soon as it had been looked to “2” it had been running on the brand new 24 volt system through the 24 volt to 12 volt converter.

(clearly if the switch had been looked to “1 + 2” it can 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 even the brand new 24v to 12v part. Additionally, to date, operating the lights directly from the system generally seems to work very well plus they don’t eat that much energy in addition to that which we were currently utilizing. The machine has become quite versatile, permitting me personally to operate the lights on either the old or system that is new as needed.
