Many so-called MPPT controllers on the market lower than $30 cannot reach >99% tracking efficiency beause we had tested them. Even worse, when you look at the result list by searching MPPT solar charge controller, many of them are cheap PWM controllers, they are hiding MPPT and PWM words on the product and listing to let customers forget it's a MPPT or PWM controller. The GreeSonic MPPT1575 controller promise the tracking efficiency >99% and the charging efficiency is about 20% higher than the traditional PWM controller, which can make the cost of the whole system much lower! What's more, it's the most compact, warterproof, simple-operated and best price MPPT controller.
