Grape 40 Amp PWM Charge Controller versus ?
I often see recommendations for the Grape Solar GS-PWM-40BT 40 Amp PWM Solar Charge Controller. The Grape controller was recommended as a potential replacement for my Renogy 30A PWM LCD Controller an...

The primary thing is the ability to program almost every single setting
Max charge voltage , boost time duration, low voltage return to boost mode, float flat voltage, i have no way y to know if it's more efficient aka (less internal loss)
But it is the most user adaptible controller i have come across
Mine is set so low voltage return to boost is the same voltage as float
If the voltage drops to lie set point , when i use the MW then, it goes right back to boost mode, aka set charge of voltage 14.8 , and not set around in float mode
You may not need the ability to do this, for me this is very helpful
