Features

  • EASY-READ BACKLIT DISPLAY: To check the PV status and the Battery status easily, the 20A solar panel regulator will cycle the PV input current and the battery voltage on the main interface with real-time value every 3 seconds, also has color code icons. With a larger screen and 50% brightness in no operation, the solar charge controller is easy to read in dim light. Allows you to see exactly what the controller was doing and how much power is being drawn in from the panel(s).
  • Li COMPATIBILITY: Not only compatible with traditional battery, the PWM controller also has clear and special icons for various Lithium batteries on the LCD screen, such as LFP for LiFePO4, Li for Ternary lithium battery, LTO for Lithium-Titanium-Oxide. With setting to Li battery type, this solar charge controller also has a function to jumpstart your lithium battery in case it gets overly discharged. Don't need to buy a new controller for the upgraded Lithium-ion batteries.
  • BATTERY COMPATIBILITY AND MAINTENANCE: Compatible with various 12v or 24v batteries, such as SLD, FLD, GEL, AGM, SLA, LiFePO4, ternary lithium battery and LTO battery. Including the ability to program the solar charge controller for best charging and maintenance of various battery types. The solar panel regulator is dependable to be your battery maintainer.
  • SOLAR PANEL REGULATOR: Max PV input voltage 55 volts, while most controller can only handle 50 volts PV input. This solar panel regulator can handle 300 watts input for 12 volts battery system, 600 watts input for 24 volts system. The Max PV input voltage is higher than most controller, which can produce more power as well.
  • NEAT AND SAFE WIRING: Come with 3 pairs of spade terminals, it is easy to grip the wires more firmly and make a neat wiring. Please note that turn the screwdriver counterclockwise first, in order to open up the wire clamp holes. hook up the battery first, positive wire, then negative wire. After that, connect the controller to the solar panel, please note that do not disconnect the battery when the solar panels are active.

This review is for the "30A Black" version, which has a more traditional look than the other 30A, which may be different internally. I am very pleased with the simple nature and good performance, given it is just a Pulse Width Modulated output. You might gain 15-20 percent output from your panels with a MPPT controller, but at a much higher price. For occasional use, charging 12v nominal batteries with a 18-21v solar panel, this will do just fine, as an extra 20% in panels is usually cheaper than the fancier controllers (depending on the size of your array of course). This controller is able to charge both lithium and lead acid batteries to the proper voltage, and there are multiple choices for chemistries within those 2 types. Cycling through the different options is easy, starting with a long press of the red button, short presses to get to the option you want to modify, and another long press to change the option. Options are stored, so it will keep them even when powered off. There is a way to do a unit reset as well, if you really mess up the options. The automatic equalization charge for lead acid batteries is nice if you keep them topped off for long periods of time. This should help prevent stratification of the acid inside the cells. The product arrived in a little cardboard box, not much protection needed for it's shape and size. The slide in terminals also appear to be nickel plated, which is a nice touch, even though the unit isn't weatherproofed at all (it doesn't claim to be either). I took off the back aluminum cover, and was surprised to see 6 MOSFETs. I lifted 1 up, and it was a CR Micro, N channel MOSFET. They are rated up to 180 amps. Both sides of the MOSFET are heat sinked (only one side has thermal tape to the back cover, the other is against the ground plane of the PCB), so there should be no problems passing 30A. This appears to be a very well engineered product. The PCB design is very good, and manufacture is good as well. The microprocessor is actually a ST micro, and it truly is a 32 bit, although it is probably overkill for this application. Upon initial power up, the controller goes through a quick boot, ~5 seconds of a spinning tick mark on the LCD. It is then ready for operation. Make sure you connect the solar panel after the battery, and not before. The load side is also controlled using MOSFETs, and will shut off when the battery voltage becomes too low, which is a nice feature. The unit will flash E01 if this is the case. Otherwise, the load can be turned on and off with the red button. I measured initial power draw at ~40mA during boot up, which settled to ~24mA after 45 seconds. Turning off the output lowered the power draw to 10mA or less. This is important if you plan to leave it on overnight, as it will slowly drain the batteries. Turning on the LCD back light with the red button adds 15-20mA, which is expected for an LED. The backlight shuts itself off automatically after a brief period, saving power. Total power dissipation within the controller was measured using the voltage drop across the positive and negative terminals, separately. The positive terminals had 5mV of drop per amp, while the negative was 1mV per amp. This is very low (positive must travel through the MOSFETs, this more drop), and represents only 0.2 watts at peak amperage at 12 volts. Upon initial use, the amperage reading displayed was consistently high, at 4.2 amps above actual. I unplugged the solar, and unplugged the controller, then replugged everything back in, and it was working normally, current was within ~0.1A of actual, accurate enough for a 30A range. I can only assume the controller makes a measurement at startup for a zero point, and somehow it was incorrect the first time, but correct since then. ... show more
