Re: Serial connections for three panels?
??? If connecting them in series, what use is there for a "combiner box or 3 into 1 Y branch connector?" They just get daisy chained.1 · -
Re: PC MeterBus Adapter FYI
As I already said, it uses an open-collector (aka open-drain) bus. Much like I2C, except it "talks" 9600 bps, half duplex, Modbus.1 · -
Re: Voltage drop when plugged into charge controller? (18-19V -> 12.7V)
Stop being pedantic. This is "Solar Beginners Corner." The difference is only the voltage drop, which wouldn't be much with a 100 W panel. The OP was expecting the panel voltage to st…1 · -
Re: Voltage drop when plugged into charge controller? (18-19V -> 12.7V)
What's important is the current, not the voltage. A PWM controller basically act like a switch. When bulk charging, the panels are simply connected directly to the battery. The voltage you see w…1 · -
Re: Over paneling a charge controller
RTFM? "PV Overcurrent: The controller will limit the battery charging current to the maximum battery current rating. Therefore, an over-sized solar array will not operate at peak power."1 ·
