Review on 30 Amp EPEVER MPPT Solar Charge Controller - 12V 24V Auto, High Input Voltage, Negative Grounded Solar Regulator for Lead-Acid and Lithium Battery Charging/Discharging by Zachary Ester

Imported charge controllers are fantastic. It's highly customizable (pro tip: bring a USB programming cable. If you can find software for it, programming will be easier), and the MODBUS communications port begs for custom configuration. . Seems to have very efficient conversion efficiency. I opened it up and looked around the inside and was impressed with the quality of the PCB processing. Often the electronics imported from this part of the world contained rather poor build quality. This device showed no signs of poor performance. I set up one of these in a remote cabin, set up an Arduino with a GSM module and plugged it into the data port on that so the system can text me every day telling me how my solar system is doing. Because it's Modbus, it's an industry standard, so you don't have to understand custom data formats. The manufacturer offers a full connection to Modbus, so it was up and running in no time.
