The solar charge controller

Science/Technology / Help With Diy Solar Installation by afotrick(m): 7:59am On Aug 01, 2023 |
So I have a 2.8 battery backup by luminous installed by a professional installer. I currently want to upgrade it to also charge with solar but I would like to do it diy. I have been doing a lot of research about it but I will like to peer review my math and numbers so I don’t damage my appliances. So I have a charge controller rated for 30amp pmw from an earlier time. It’s connected to a 150 watt solar panel 12 volts. The current inverter is a 2.8kva inverter with 2 batteries. Which makes a 24v system. Now I plan to order 2 more panels 1 200watt 12v panel 1 300 watt 24v panel My plan is to connect the existing 12v 150watt panel to the new 12v 200 watt panel in series to make a 24v Then connect the 24v in parallel to the 300 watt 24v panel. This should give an output of around 28amps and 24 v Which is about 650watt in total The charge controller has a max of 780 watt for 24v Is there an issue with this setup or am I making any mistake. Is there any other device I need? I know I need a surge protector and a DC breaker but not sure where to get those yet. Please house I need your help. |

Webmasters / Re: Post your PHP Problems Here by afotrick(m): 11:11am On Sep 29, 2015 |
satmaniac: Hello ur script is alittle buggy cause of ur use of single and double quotes. Try this instead $query = "INSERT INTO user VALUES('', '$firstname', '$name', '$email', '$password', '$confirmpassword', '$username',' $sex')"; The mistake u made is pputting . which means concatenation in php between the sql query will only cause problem if u dont break it will double quote like u statted with. If u started with single quote then wen u concatenate. U end each string with single also. |

Politics / Re: Nigerians Tweet On Buhari 100 Wasted Days- #100wasteddays by afotrick(m): 6:46am On Aug 27, 2015 |
sorry to say. Nigerians are hypocritic in nature. i dont see any hash tag #6years wasted. yet after six years i see our youths begging for alms jobs, our mothers fighting for little food in the market our fathers paying taxes they dont get any return from. only to be paid into the accounts of some bastards sorry to say. so now a man comes in less dan 100 days, even if he does notin, is trying and we can all see is trying to put us all back on track. yet we want to nail him to the hauge. its a pity anyway. |

Programming / Help With A C Program Code To Solve A Differential Eqn Using Rungekutta 4th Ord by afotrick(m): 9:26pm On Feb 23, 2015 |
hello.any one advanced in runge kutta 4th order and c programing? Am just an undergraduate working on it. I need help with this code. It sussessfully solves a system of differential equations using runge kutta 4th order, but my lecturer wants something else. something i dont know how to do. the code originally has the question already in the program, but what am required to do is make the program ask the question like an interface asking the question and parameters to solve. i believe u will understand when i post the code. #define X0 1.0 #define Xn 2.0 #define STEPLEN 10 #define Y1 1 //initial condition for y1 at x=0 #define Y2 0 //initial condition for y2 at x=0 #include <stdio.h> #include <math.h> #include <stdlib.h> double f1(double x,double y1,double y2) { //a function to solve the functions 2 using x and y return(y2); } double f2(double x,double y1,double y2) { //a function to solve the functions 1 using x and y return(x*log(x) - (2*y1)/(x*x) + (2*y2)/x); } main() { double x,y1[STEPLEN],y2[STEPLEN]; double xmid,k1[2],k2[2],k3[2],k4[2],h = (double)(Xn - X0)/STEPLEN; x = X0; y1[0]=Y1; y2[0]=Y2; int i; printf("This are the initial values. y1=%.10f y2=%.10f and h=%f\n\n", y1[0], y2[0],h); //printf("x\t|k1\t|k2\t|k3\t|k4\t|y\n\n" for(i=0; i<STEPLEN; i++){ k1[0]=h * f1(x,y1[i],y2[i]); k1[1]=h * f2(x,y1[i],y2[i]); xmid = x + h/2.0; k2[0] = h * f1(xmid, y1[i] + k1[0] * 1/2.0, y2[i] + k1[1] * 1/2.0); k2[1] = h * f2(xmid, y1[i] + k1[0] * 1/2.0, y2[i] + k1[1] * 1/2.0); k3[0] = h * f1(xmid, y1[i] + k2[0] * 1/2.0, y2[i] + k2[1] * 1/2.0); k3[1] = h * f2(xmid, y1[i] + k2[0] * 1/2.0, y2[i] + k2[1] * 1/2.0); k4[0] = h * f1(x + h, y1[i] + k3[0] , y2[i] + k3[1]); k4[1] = h * f2(x + h, y1[i] + k3[0] , y2[i] + k3[1]); y1[i+1] = y1[i] + (k1[0] + 2*k2[0] + 2*k3[0] + k4[0])/6; y2[i+1] = y2[i] + (k1[1] + 2*k2[1] + 2*k3[1] + k4[1])/6; printf("When x=%f\n",x+h); printf("k1 for y1=%.10f\n",k1[0]); printf("k1 for y2=%.10f\n",k1[1]); printf("k2 for y1=%.10f\n",k2[0]); printf("k2 for y2=%.10f\n",k2[1]); printf("k3 for y1=%.10f\n",k3[0]); printf("k3 for y2=%.10f\n",k3[1]); printf("k4 for y1=%.10f\n",k4[0]); printf("k4 for y2=%.10f\n",k4[1]); printf("y1 when x is %f=\t%.10f\n",x+h,y1[i+1]); printf("y2 when x is %f=\t%.10f\n\n",x+h,y2[i+1]); // printf("%f %f %f %f %f %f %f %f %f %f \n",k1[0],k1[1],k2[0],k2[1],k3[0],k3[1],k4[0],k4[1],y1[i+1],y2[i+1]); x = x+h; } system("pause" } please if u dont mind contact me by email @ afotrick2011@gmail.com Please. your help will be very much apprciated. 1 Like |
