Pic16F73 50A PWM solar charge controller
12V,24V and 48V auto battery detect (connect battery first and then solar)
conman anode seven segment display (display bat-V, Chg-Amp, and overload )
short circuit and overload detection
optional relay output for external battery charger (when solar not...
thanks" BradtheRad "... I think disconnect the PV temporarily is better idea. because i want to energies a relay when PV voltages are lower then 13 volt.
I not understand the procedure of measuring SOLAR and BATTERY voltages. The time the MOSFET Q1 ON, the voltage will be nearly the same on solar and Battery side even if we start to charge the battery from low voltage level...so how could we measure the battery and solar voltage separately while...
voltage measure problem in solar charger
This technique is used in almost all Chinese PWM Solar Charge Controllers. But I not understand the procedure of measuring SOLAR and BATTERY voltages. The time the MOSFET Q1 and Q2 ON, the voltage will be nearly the same on solar and Battery side even if...
I want to design a Two switch Farward Converter. So is there Gapped required in this topology (like a single switch Flyback converter) or not. My second question is, can I calculate the transformer turns ratio of 2 switch farward converter like a single switch flyback converter or it is a...
