Review on ⚡️ Flexzion PWM Solar Charge Controller with LCD Display (30A amp 12V 24V volt) - Multi-Function Adjustable Load Regulator, Battery Charger, Street Light Timer - Dual USB Port for Solar Panel Battery and Renewable Power by Rodney Gonzalez

Basically you buy an original Epever Tracer 2210A at a much lower price. Never waste time and money on inferior PWM controllers. Get this for almost the same price. The MPPT process (via a huge inductor inside) always charges your battery at the optimal efficiency point (regardless of which solar point you use). This make/model has all control settings available to you on the LCD or via available expansion modules (Wi-Fi/Bluetooth/Remote Wired Panel/PC Control Software). A true professional product with full documentation/software available on the Epever manufacturer's website. .I'm adding a Bluetooth module so you can see what's happening on your system at a glance.
