20A Solar Charge Controller Solar System Protection Regulator 12V/24V Max480W Sl02A-20A Review

Pros:
Loaded with features / programmable / LED
Light output terminal for dusk/dawn control (programmable)
Works with a variety of battery chemistry (flooded, VRLA, Gel, Lithium) based on voltage, float parameters (programmable).
Various LED status - indicates solar panel output / battery status / separate light output status
Affordable
Beefy, sturdy feel overall
Consumes very little power itself
Auto-sensing 12v/24v operation

Cons:
The screw holes are a bit small, requiring small flat bladed screw driver
The 6 terminals are a bit on the flimsy side (not very sturdy) and can only accommodate smaller gauge wires (like 14, 16, 18 etc)
The programmable features & LED are unnecessary. This adds to the cost of manufacturing process. A series
of jumper blocks could work instead, since users would not be switching back and forth often.
Difficult to program with one button
Difficult to understand manual

Recommended buy - YES
