Review on 🌞 Morningstar TriStar TS-60M: Industry's Best 60A PWM Solar Charge Controller for 12V/24V/48V Batteries with Unbeatable Reliability and Advanced Diagnostics by Donald Cox

Very compact. Easy to install. Proper instructions provided you read and practice until it becomes clear (quickly) what the graphics mean. Lots of useful information available. Good backlight. The yellow arrow keys take a bit of getting used to as they don't feel like clickable keys at all, but once I got used to the feel they worked well, albeit erratically at times. When the block is in standby mode, pressing one of the buttons activates the block, after which the next button press actually performs its function. No problem if you know how it works (it's in the manual). I definitely recommend this calculator.
