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
10-4, makes sense.
I hadn't read the Tech Specs before, just did and the trailing two numbers of the model numbers is the rated Amps. That would indicate I most likely do have a 30A SR-HP2430.
Then it would appear the main differences are the 10A delta and most importantly, the ability to fine tune the charge programming via BT.
Again, appreciate all the comments, and keep 'em coming, as this is helping me to learn.
