   This charge controller is a beast! It can handle a lot of power from my solar panels, and I seem to be getting pretty efficient energy delivery from my panels. Currently running up to 300 watts at 12v through it, and planning to add more panels soon (I have the 50amp version… FYI the 25amp version would limit out at 300). I really like how easy it is to connect everything. The connectors just snap on and off, which make it incredibly easy to hook up and disconnect the wires. This is a huge plus any time I need to work on the system or add a panel. The only downside is that it doesn’t have a screen. I’d love to be able to see things like how much power is coming in and how my batteries are doing. It does get warm on high-sun days. There are vents and the heat dissipates but plan for some space to let the heat go.

   Overall, it’s a great option if you need a powerful charge controller. Just wish it had a screen so I can see what it’s doing without additional instruments.

   I had a nice sunny day to put this charge controller through some tests. It has some nicer features, such as it tested fine with higher end LiFePO4 and SLA batteries and is extremely simple to set up. The settings are all preset, so all that’s needed is to select the correct battery chemistry. The connections are very convenient, with a removal terminal block and more than ample room for heavier gauge wire than most. The manual states 130V max input on its first page (not in the specs grid, though it should be clearly noted there) and 600W max in the spec sheet. I ran one of my spare 540W 49VOC bifacial panels into it for testing, but I will be connecting two of them in series mounted on the RV and the charge controller will feed our 300Ah LiFePO4. While it performs well, it’s worth noting that it lacks some features that are pretty common in similarly priced units. There is no way to change the presets, there’s no communication capabilities, no LCD, no temp sensor (optional add-on), and the aluminum case is the heatsink but there’s only around 1/4″ space in the back of the unit. At least it’s not mounted totally flush, but when it’s quite hot out, the solar string is pushing lots of power, and the battery is soaking up the charge, the unit would likely benefit from more clearance and better airflow. It seems a bit spendy when comparing it to many of the bargains out there right now, however, many of those bargain units have a huge fail rate. If I run into any issues with this charge controller I’ll update the review.

   Got it with the wrong manual but that’s OK I’m a bit confused the description claims it’s compatible with gel batteries nothing in the manual that I see on line gives every battery except gel
   

4. So far so good Verified Buyer – 17 March 2025

   I got the 25amp, and two 50amp models for my solar battery bank. I have used 4 other brands of solar charge controllers and these by far are the best! They cab not be programed but the simple selection of battery type there is no need. Use these for my AGM battery and if latter on I wanna upgrade, no problem just a press of a button and it can change the battery type. Love it!

   The EcoBoxx MPPT Solar Charge Controller comes is offered in two size 25A and 50A. I got the 50A model. It is rated for max PV input of 135V, current 40A and power of 600W. Nominal output voltage is 12V/24V (auto selected) with a charge capacity of 50A. MPPT controller as the most efficient. It measures about 10 1/4″ L x 7 7/8″ W (counting the mounting brackets) x 2 3/4″ T. It is designed to be wall mounted with two fans at the top and intakes on each side. Hookup is made easy because they use a module system, where you attach the leads to a connector bus which slips into a collar (for easy removal) and both push into a set of connectors in the unit. Once connected you use a simple push button to select the battery type (flooded, AGM or Lithium). Its a simple, but powerful charge controller that does what it suppose to. Having a readout or Bluetooth connectivity to get numeric data would be nice. It has a temperature sensor socket, but no details on a sensor (which I do not need here in S. Fla.). It is perfect for a small to midsize solar power system like in an RV, camp or part of an emergency power backup for storms.
