Our MPPT solar charge controllermainly have two kinds, one looks like above picture, it is waterproof IP67, we call it SMR-MPPT series and another kind have LCD display with information shown on the screen, which is installed in home, RV, power station and so on, we named it Magic (MT)series. Now we talk about the first series, SMR-MPPT1575, it suits for lead acid battery and lithium battery, 12/24V system, max module 400W.
It has two Led indicators, green led and red led, green led shows battery charging status and red led shows protection functions. Now in order to meet customers’ demand, we upgrade this item and add yellow indicator, its status tell users battery status, low or normal or over voltage protection/low voltage protection. The new item also increase charging efficiency. Its charging conversion effiency up to 96.5%.
