Max6048-E is a sort of solar controller 48V.
It means 12/24/36/48V system voltage, 60A maximum charging current, and 30A maximum discharging current.
They are a little expensive, but they deserve the price after testing sample.
The easy way to distinguish the quality of a PWM product is to test it. Generally, the temperature of good-quality PWM products is not high; the temperature of poor-quality controllers is high. After several cycles of testing, you can determine the true quality of this product. And some new customers who have strict requirements for new product standards will do this.
We know that some companies will use low-current PWM instead of high-current PWM. For example, the controller is 20A, but they use 30A stickers. Of course, you think the price is very cheap, but in fact, you bought a low-current product at a higher price. This is an act of deceiving consumers. We absolutely do such dishonest things.
