Replaced a 45A EPSOLAR MPPT that I have had for about 10 years. It is clearly superior with greater accuracy of values and no errors so far. With the previous one, I experienced overvoltage problems at the input of the inverter, usually during midday hours, which led to system failure. It is smaller in size, lighter, with a cover made of thick plastic that is difficult to distort but does not break. It is designed in the Netherlands but manufactured in India. It accepts 4 different input voltages for the batteries, correspondingly expanding the charger's power. I am operating at 24V, which corresponds to about 1000W. It has a port called VE, where you can connect devices for information, updates, or charger configuration. Overall, I am very satisfied and have overcome my initial concerns. It has software and an application for mobile phones and computers, but it requires the purchase of additional components to be connected to the charger's port. The simplest one connects via Bluetooth, which means you only have information when you are within range... "Bluetooth". Yes, I highly recommend it, as well as the specific company in general, because it has very good support and many control devices for all unit sizes.
