12V/24V Auto PWM Solar Char Controller With LCD Dual USB 5V Output Solar Cell Panel Regulator PV Home ,Easy to Use

The lower the system volta, the smaller the no-load loss. Light control on 5V, light controloff 6V (light control onplus1 V) Automatic recognition of12V/24V An upgraded 3-sta PWM charging algorithm is adopted.Application of an equalizing char to the battery periodically or when over dischard can effectively prevent the battery from non-equalization andsulfuration,thus extending the battery's service life (with the exception of Land lithium batteries).
