Sierra Leone 3KW Household Off-grid System Upgrade Case
African 3KW household off-grid system upgrade case:
The customer previously purchased a PWM controller and a 12V2KW modified wave inverter power supply system locally, but from the date of installation, the whole system can only drive refrigerators or televisions to work alone, unable to meet daily needs, and then found Nuocheng Photovoltaic's store for technical help. Through door-to-door inspection for customers, MPPT controller with higher conversion efficiency and 48V3000W pure sine wave inverter have been replaced, which can not only drive the freezer and TV set to work at the same time, but also make the 5 electric fans and 3 ceiling fans in the home work at the same time, which perfectly solves the daily needs. The customer said that he would buy air conditioner next time and let us upgrade the solar energy.
