Re: meaning of this ccs code http: if(s&8) OUTPUT_HIGH(PIN_A3); else OUPUT_HIGH(PI
You may not find this in CCS programming manual. This is just C code. Search the internet for Bitwise operations in C.
8 in binary is equal to 00001000. So it is the bit 3 which is one and all other bits are...
from the data you provided, now I have the follow comments
1. This kit have two optocoupler, one op amp, one 28 pin microcontroller, one LM555 IC and three POTs.
2. Most probably this is a sinewave KIT.
3. Since the Kit uses two optocoupler 4N35 and generally one opto is used for Input AC sense...
From the pictures you attached, I have the following conclusions
a) This UPS doesn't have low cost KIT.
b) There are two POTs (Variable resistors) for adjustment but regarding their purpose the picture is unclear.
c) I may be able to comments further if you can provide the ICs Number (Mark Red)...
From the detail you provided it seems that the kit used inside the UPS doesn't have voltage regulation / fix volt option. This type of kits (low cost) works the way you describe. The output voltage is intentionally set high and is reduced as you put load on it.
If you want to have a stabilized...
Yes, sure, you can contact me via private message or mobile phone. But publically I cannt as this is a commercial product and I have to seek prior permission.

You can obtain solar charger for high voltage in Lahore from QPS www.qps-intl.com
Due to contractual obligations, I cannot publish my design/code for MPPT charge controllers. But if you need assistance, in your design, I surely will help the best I can.
I have designed, developed and installed a number of solar controllers and panels. I never have faced any performance degradation. No adjustment is needed. Yes, a 24V controller cannot be connected to 12V.
Nothing will happen. In most cases the charge controllers will not turn ON because they...
ch wazir is using identical charge controllers. So this should not be a problem.
The transition from bulk charge to float will not harm anything even if there is some difference between float voltage level of both controllers.
I never heard /experienced that current flow back from battery to...
The output of two 24V MPPT charge Controller can be combined. I would not recommend to combine the input of the controllers.
The best solution could be, connect half the number of solar panels to one charge controller and the remaining to other controller and combine the output to the battery.
Most stabilizer have an output specification such as 220V ±10%, which means that the output can be in range of 200 to 240V. So from the data you provided, one cannot deduce whether your stabilizer has any problem or not. You should check the output voltage below 200 Volts. e.g. output voltage...
As per your schematic, you are using the transistor in common collector mode. In this configuration the output voltage at buzzer will be from min 3.8V to max 4.4V. In real hardware 3.8V should activate the buzzer. But I will recommend to check the minimum operating specification of the buzzer...
